This document summarizes the effects of endodontic treatment on teeth and considerations for restoring endodontically treated teeth. Key points include:
- Endodontic treatment can result in loss of tooth structure, altered physical properties making teeth more brittle, and discoloration.
- Remaining tooth structure, function, and aesthetics must be evaluated to determine the appropriate restoration. Teeth with minimal structure may be restored with composites while those with heavier function typically need crowns.
- Temporary cements must be completely removed before bonding permanent restorations to avoid inhibiting the bond. Teeth exposed to sodium hypochlorite also require treatment to reverse its oxidizing effects.

This document discusses post and core procedures for endodontically treated teeth. It covers objectives, indications, considerations for post length, diameter and design. Ideal post length is 1-2 mm shorter than the root and diameter should allow at least 1 mm of dentin surrounding the post. A ferrule is important to improve structural integrity. Post types discussed include custom cast metal posts, prefabricated metal posts like stainless steel and titanium, and non-metal options like carbon fiber, fiber-reinforced and zirconia posts. Fiber posts are more esthetic and flexible but have less strength than metal or zirconia posts. Proper diagnosis and treatment planning is required to select the best post and core for

Restoration of endodontically treated teethAnish Amin
Restoration of endodontically treated teeth often requires posts and cores to provide adequate retention and resistance for weakened teeth. Key principles for posts and cores include preserving tooth structure, maximizing retention through post length and design, and providing resistance through features like ferrules. Posts and cores are indicated when there is significant loss of coronal tooth structure and the risk of fracture is high. The amount of remaining tooth structure, presence of a ferrule, and post length and design all influence the success of a post and core restoration.
This document provides information on restoring endodontically treated teeth. It discusses the historical use of posts, objectives of restoration, changes to teeth after endodontic treatment, and factors to consider in treatment planning. Custom made posts involve preparing the tooth and canal, making a resin pattern of the canal, and casting a post and core. Proper ferrule effect, post length and diameter are important considerations.

This document discusses the restoration of endodontically treated teeth. It begins by noting the increased interest in restoring such teeth and challenges posed by coronal tooth structure loss. The complete coverage crown is identified as the ideal restoration. Posts are needed when inadequate structure remains to retain a core. Key considerations for restoration include coronal sealing, preserving remaining structure, and distributing stresses favorably. Treatment planning depends on the extent of coronal and root damage. Post selection is based on length, diameter, shape, and location. Custom cast and prefabricated posts each have advantages and disadvantages. The document provides guidelines for restoration procedures and materials selection.

- Non-vital teeth require careful treatment planning and restoration to strengthen teeth and prevent fracture under stress.
- Key factors to consider include the amount of remaining tooth structure, the tooth's position and function, and esthetic needs. Teeth with little structure left require dowels, cores and crowns for reinforcement.
- Dowels provide retention for cores within root canals. Ideal dowels are retentive, protect remaining tooth structure and roots, and allow for strong bonding of cores and crowns.
- Cores build up coronal structure for crowns. Different materials include cast cores, amalgam, composite resin and glass ionomers, each with strengths and weaknesses for retention, bond strength

Esthetic crowns in pediatric dentistry.pptxgahanamuthamma
Esthetic crowns are used in pediatric dentistry to restore teeth damaged by decay in a way that preserves function and improves appearance. There are various types of crowns including strip crowns made of composite, pre-veneered stainless steel crowns, polycarbonate crowns, and ceramic crowns. Indications include extensive decay, fractures, discoloration or pulp therapy. Contraindications include non-restorable teeth. Placement involves tooth preparation and selection of an appropriately sized crown, which is then bonded or cemented onto the prepared tooth.

The Carolina bridge is an all-porcelain bonded prosthesis that can replace single missing anterior teeth without tooth preparation. It involves bonding a custom porcelain pontic to the adjacent teeth using resin composite connectors. It requires adequate surface area between teeth for bonding. The Carolina bridge provides an esthetic and reversible interim solution as it preserves teeth and bone for future implants. It is contraindicated when there is inadequate interproximal space, deep overbite, short teeth, or teeth with large restorations.

The document discusses pontic design for fixed partial dentures (FPDs). It provides definitions of pontics, outlines requirements and basic design principles focusing on cleansability, appearance and strength. Key considerations in pontic design include biological factors like ridge contact, oral hygiene and materials used, as well as mechanical factors. Common pontic types are described based on their relationship to soft tissues, materials and retention features. Pre-treatment assessment of the pontic space and tissues is also emphasized for successful pontic design.
Fixed dentures are dentures that are permanently fixed in the oral cavity and cannot be removed without help from a dentist. They can be permanently cemented to a patient's own teeth or implanted abutments, or mounted on pillar implants with screws allowing for removal. Common types of fixed dentures include crown inlays, cast dowel crowns, veneers, crowns, and prosthetic bridges. Proper preparation of abutment teeth is important for fixed dentures and involves reducing tooth tissues while maintaining anatomical shape and creating parallel axial walls slightly converging at the chamfer.

It introduces key terms like physiologic occlusion and defines different occlusion schemes like balanced articulation and monoplane articulation. The document discusses advantages and disadvantages of using anatomic versus non-anatomic teeth for complete dentures. It also outlines requirements for maintaining denture stability, such as balanced occlusal contacts and control of horizontal forces. The goal of occlusion for complete dentures is to re-establish the homeostasis of the masticatory system disrupted by edentulism.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

4. INTRODUCTION
• Initially only extraction
• From past 20 – 30 years, increased interest in restoring.
• It is well known that with proper endodontic treatment and
adequate restoration, pulpless teeth can serve indefinitely as
an integral part of the dental apparatus, provided the
supporting structures are not compromised.
www.indiandentalacademy.com
5. • From the time of Pierre Fauchard till date a wide range of
materials, techniques and designs have been described to
restore endodontically treated teeth.
• However, there is no clear consensus regarding an ideal
system, this is because each tooth presents with a unique
requirement.
• A thorough understanding of the proper use of posts and cores
will enable clinicians of today to provide an optimum
restoration that uniquely balances between maximizing
retention of the tooth while minimizing the risk of failure.
www.indiandentalacademy.com
7. HISTORY AND EVOLUTION
• Restoration of endodontically treated tooth by a post to retain a
crown dates back more than 250 years.
• In 1747, Pierre Fauchard a French dentist used “Tenons”
which were metal posts (Gold or silver) into the roots of teeth to
retain bridges. He used heat softened adhesive called MASTIC.
www.indiandentalacademy.com
8. • Later wood replaced metal as the post material, and the “Pivot
Crown”, a wooden post fitted to an artificial crown and to the
root canal became popular. But they led to repeated episodes of
swelling and pain.
• In mid 1800 –Dr.F.H.Clark – developed a “spring loaded
dowel” a retentive device consisting of a metal tube in the
canal and a split metal dowel which was inserted into it. They
also had channels for continuous suppuration from the
underlying tissues.
www.indiandentalacademy.com
9. • G.V. Black developed porcelain fused to metal crown held in by
a screw inserted into a canal filled with gold foil.
• In 1878 , the “Richmond Crown”, a single piece post-retained
crown with a porcelain facing was engineered to function as a
bridge retainer.
www.indiandentalacademy.com
10. • During the 1930s, the custom cast post and core was developed
to replace the one piece post crowns, because of their drawback
of using in diverging roots and difficulty in removal and
replacement of FPD crowns.
• In 1960s prefabricated posts were introduced.
• 1990 Duret et al described a non metallic material for the
fabrication of posts based on carbon fibres reinforcement
principle.
www.indiandentalacademy.com
14. ENDODONTIC EVALUATION
• Good apical seal as revealed by radiographs.
• No tenderness on percussion
• No apical sensitivity
• No exudate
• No fistula
• No active inflammation.
www.indiandentalacademy.com
15. • Periodontal health is critical to the long term success of teeth that
have been endodontically treated and restored.
• Periodontal condition must be assessed before endodontic
treatment, and the effect of planned restoration on the attachment
apparatus must be considered.
• Any structural defects of teeth should be considered that jeopardize
coronal restoration.
• Extensive caries, tooth fracture, previous restoration, perforation
and external resorption can destroy tooth structure at the level of
the periodontal attachment.
PERIODONTAL EVALUATION
www.indiandentalacademy.com
16. RESTORATIVE EVALUATION
Depends on,
• Amount of remaining tooth structure
• Tooth type
• Morphology
• Occlusal and prosthetic forces
• Periodontal support
www.indiandentalacademy.com
18. ESTHETIC EVALUATION
• Potential esthetic complication should be investigated before
initiation of endodontic therapy.
• Thin gingiva may transmit a shadow of dark root through the
tissue.
• Metal or dark carbon fiber post and amalgam placed in the canal
can result in unacceptable gingival discoloration from the
underlying root.
www.indiandentalacademy.com
19. • The translucency of All-ceramic crowns must be considered in
the selection of dowel and build-up materials.
• Tooth colored carbon fiber glass-reinforced composite resin, or
zirconia posts can be used in esthetic areas. Similarly, tooth
colored, rather than opaque, composite core material should be
selected for esthetics.
• An intact endodontically treated tooth requires critical control of
endodontic materials in the coronal third of the canal and pulp
chamber in order to maintain its color and translucency.
www.indiandentalacademy.com
20. • Gutta percha discoloration can be visible in the coronal aspect
of an endodontically treated tooth and should be limited to an
apical level in the root.
• Endodontic and restorative materials in these esthetically
critical cases must be selected to provide the best health service
with the minimum of esthetic compromise.
www.indiandentalacademy.com
21. TREATMENT GOALS
• to maintain the coronal and apical seal of the root canal
filling material
• to protect and preserve remaining tooth structure
• to provide a supportive and retentive foundation for the
placement of a definite restoration
• To restore function and esthetics.
www.indiandentalacademy.com
23. Post
The post is defined as a relatively rigid, metallic or non metallic restorative material
inserted into the root canal of a nonvital tooth to aid in retention of a core
component and to transmit the forces .
www.indiandentalacademy.com
24. INDICATIONS FOR POST
• To retain the restoration
• To protect remaining tooth structure
• Marginal integrity
• To stabilize radicular fractures
www.indiandentalacademy.com
25. CONTRAINDICATIONS FOR POST
• Abnormal root anatomy.
• Extensive caries including root caries.
• Perforations.
• External resorption.
• Short roots.
• Dilacerated roots.
• Blunderbuss canal.
• Young patients with coronal fracture, with incomplete root
formation.
• Patients with poor oral hygiene.
www.indiandentalacademy.com
26. Ideal requirements of post
• Simple and safe.
• Biocompatible.
• Should support the core and crown.
• Should provide resistance for stresses.
• Maximum protection of root.
• Adequate retention within the root.
• Pleasing esthetics, when indicated.
• High radiographic visibility.
• Easily removable.
• Less expensive.

32. CLINICAL PROTOCOL FOR RESTORING
ENDODONTICALLY TREATED TEETH
• Anterior teeth
• Pulp less anterior teeth can also be conservatively
restored with a bonded composite resin restoration rather
than artificial crown.
• A laminate veneer offers a conservative alternative if the
facial surface is intact with moderate discolouration. .
www.indiandentalacademy.com
33. • Anterior teeth that exhibit mesial and distal restoration should
be restored with a post and core prior to the placement of a
crown.
• Mandibular incisors and maxillary lateral incisors would
always require a post and core before placing an artificial
crown.
www.indiandentalacademy.com
34. Posterior teeth
• The need for a core or a post
and core is determined on
the basis of remaining tooth
structures as well as
expected occlusal and
prosthetic forces that will be
applied
www.indiandentalacademy.com
35. • Clinical consideration
• The apical seal, alveolar bone support, and root
morphology are all important considerations when
determining post size and depth. Anatomy and morphology of
teeth also should be considered when planning for a post
• When posts are to be used in maxillary molars, the palatal
canal should be used because of its relatively large and straight
configuration
www.indiandentalacademy.com
37. • . In mandibular molars, the distal canal should be used
because of the root morphology and size of the canal.
• The buccal roots in maxillary molars and the mesial root of
mandibular molars are not good candidates to receive a post
because of their size, morphology and curvature
www.indiandentalacademy.com
38. • When feasible, post placement should be carried out under the
aseptic conditions provided by rubber dam isolating the post
and prevents bacterial contamination of the radicular space by
salivary leakage.
www.indiandentalacademy.com
39. • Post length
• The length of apical seal remaining after post preparation
and the degree to which it was disturbed during post hole
preparation can influence the long term success of the
restoration. When ever mechanical preparation of the post hole
is required, 4-5 mm of undisturbed apical gutta percha should
remain after post preparation
www.indiandentalacademy.com
41. • Traditional view of post length have advocated that the post be
Equal to the height of the clinical crown.
One and one half times the length of the clinical crown and
Two third the length of the remaining root
www.indiandentalacademy.com
42. • Post Width
• The size of a post is dependent on the root width and
canal morphology. In general, the width of a post should not
be larger than one third of the root width at its narrowest
dimension. In addition, the post should be surrounded by at
least 1 mm of sound dentin
www.indiandentalacademy.com
43. • This point is especially critical in the apical area where the
root narrows and stresses are concentrated. Small diameter
posts provide greater resistance to fracture as compared with
larger diameter posts, and evidence exists indicating that the
post diameter has no significance effect on retention.
www.indiandentalacademy.com
44. FACTORS AFFECTING RETENTION OF POST
SYSTEMS
• Variables reported to affect retention include length, diameter
and design of the post, canal shape and preparation, luting
medium, method of cementation, and location in the dental
arch.
www.indiandentalacademy.com
45. . Post Length
• The post should equal the inciso-cervical or occluso-cervical
dimension of the crown.
• The post should be larger than the crown.
• The post should be 1/3rd the length of the crown.
• The post should be a certain fraction of the length of the root
such as one half, two thirds, or four fifths.
• The post should end halfway between the crestal bone and the
root apex.
• The post should be as long as possible without disturbing the
apical seal.
www.indiandentalacademy.com
49. • The length of the post has a significant effect on its retention
and in most instances, the more deeply the post is placed, the
more retentive it becomes
www.indiandentalacademy.com
50. • posts with a length of at least 3- quarters of the length of the
root offered the greatest rigidity and least root deflection
(bending) when compared with posts that were a half or a
quarter the root length.
• Short posts are especially dangerous and have a much higher
failure rate.
www.indiandentalacademy.com
51. Post Diameter
• Increasing the diameter of the post does not provide a
significant increase in the retention of the post, however, it
can increase the stiffness of the post at the expense of the
remaining dentin and the fracture resistance of the root.
www.indiandentalacademy.com
52. • Therefore post diameter must be controlled to preserve
radicular dentin, reduce the potential for perforations, and
permit the tooth to resist fracture
www.indiandentalacademy.com
53. • . Post Design
• 6 basic commercial systems available as follows:
1. Tapered, smooth-sided posts.
2. Parallel-sided, serrated, and vented posts.
3. Tapered, self-threaded posts.
4. Parallel-sided, threaded, split-shank posts.
5. Parallel-sided, threaded posts.
6. Carbon-fiber posts
www.indiandentalacademy.com
54. Posts systems
• Tapered post, Non threaded
• A tapered post is less retentive than a parallel post.
Tapered posts generally will have a wedging action on the root
and have a relatively low retention rate.
• These posts also have been shown to be less successful than
placement of no post at all
www.indiandentalacademy.com
55. • . For these reasons, this type of post is only recommended for
very tapered canals in which parallel sided posts would require
excessive tooth preparation.
•
www.indiandentalacademy.com
56. Parallel sided posts, Threaded or Non threaded and inactive
Parallel sided post design
offer increased retention
over tapered design.
These have excellent
clinical retention and
failures are caused most
often by dislodgement.
www.indiandentalacademy.com
57. advantages
ease of placement,
minimal stress production within the root,
and good retention,
as well as offering the added advantage of allowing final tooth
preparation during the same appointment.
www.indiandentalacademy.com
58. • . Parallel sided posts, Threaded, Active.
• They rely on some form of mechanical engagement of
cutting flute into dentin to gain increased retention.
• These are the most controversial type of post category.
• Posts in this group have been shown to induce increased
stresses with in the root, which may later lead to root fracture.
www.indiandentalacademy.com
59. • If a threaded post is selected for use, there must be an attempt
to minimize internal stresses from thread placement
• This category of posts is indicated only for very short root in
which use of a nonthreaded post would result in failure due to
lack of length for retention.
www.indiandentalacademy.com
60. Amalgam Coronal – Radicular Dowel Core
• It is not an absolute requirements that an endodontically
treated tooth should have a dowel placed in the root. As
already pointed out, this decision should be made after careful
evaluation of the previously described criteria of remaining
tooth structure, tooth type and morphlogy arch position,
occlusal forces, and periodontal status
www.indiandentalacademy.com
61. • Auxillary pins should be employed with this technique only if
additional retention is deemed absolutely necessary
www.indiandentalacademy.com
62. • Luting Agents
• Luting agents, including zinc phosphate, polycarboxylate,
glass ionomer, and filled and unfilled resin cements
• The choice of dental cement for post cementation is essentially
one of operator preference
www.indiandentalacademy.com
63. • Glass ionomer, resin, and zinc phosphate cements all have
been shown to the acceptable for post placement.
• The cementation of custom cast or prefabricated dowel and
core foundations must be carried out in an isolated
environment to minimize entry of bacteria into the prepared
canal and aid to moisture control.
www.indiandentalacademy.com
64. • . Any moisture remaining in the prepared canal will
significantly diminish retention of the post.
www.indiandentalacademy.com
65. • Canal Shape
• Because the predominant canal shape is ovoid and the
walls of prefabricated posts are commonly parallel, the
majority of luted prefabricated posts are unlikely to adapt well
along their entire interface with the canal walls.
• As a result, the post may not fit the preparation closely, and
the luting agent may not totally fill the interface.
www.indiandentalacademy.com
66. Preparation Of The Canal Space And Tooth
• When necessary, gutta percha should be removed with an
endodontic heat carrier until the desired length is reached.
• A minimum of 4 to 5 mm of gutta percha must remain to
preserve the apical seal.
www.indiandentalacademy.com
70. • twist drills should not be used to remove filling materials.
Twist drills also should not be forced but should passively
follow the course of the previously established canal. Stops
should be placed on engine-mounted drills at the desired depth
as an added precaution.
www.indiandentalacademy.com
73. .
Carbon fiber reinforced epoxy resin posts
• Most prefabricated posts are metallic, but there are several
newer nonmetallic system available.
• A post fabricated from a carbon fiber reinforced epoxy resin
was developed in France by Duret and Renaud, and became
commercially available in Sweden in 1992
www.indiandentalacademy.com
74. • Carbon fiber reinforced epoxy resin is a recently introduced
dental restorative material composed of unidirectional carbon
fibers that are 8 μm in diameter embedded in a resin matrix.
The material is radiolucent and appears to be biocompatible
www.indiandentalacademy.com
75. • In vitro studies have indicated that these carbon fiber posts
possessed inferior strength compared to metal posts
• their ability to bond to adhesive dental resins appears
unremarkable, and their bond can be improved with
mechanical retention such as serrations.
www.indiandentalacademy.com
77. Zirconia posts.
• With recent advances in ceramic technology, the all ceramic
crown has become more popular
• The response to the need for a post that possesses optical
properties compatible with an all ceramic crown, an all
ceramic post has been developed.
• This post is composed of zirconium oxide
www.indiandentalacademy.com
79. • The post is made from fine grain, dense tetragonal zirconium
poly-crystals (TZP), and the zirconia post has been reported to
possess high flexural strength and fracture toughness
• zirconia post was designed for use with an adhesive resin
cement.
• Ceramics are tough materials with high compressive strengths,
but are brittle when subjected to shearing forces
www.indiandentalacademy.com
80. Woven fiber composite materials
• The manufacturer of a cold glass plasma treated polyethylene
woven fiber has suggested this material in a resin composite to
provide corono-radicular stabilization for pulp less teeth.
www.indiandentalacademy.com
81. • These prefabricated posts
embedded in the woven
fiber composite were not as
strong as cast posts and
cores, but were less likely to
cause fracture of the roots
when subjected to failure
loads
www.indiandentalacademy.com
82. CORE MATERIALS
• When prefabricated posts are used, the core build up should be
either in amalgam, glass ionomer, or composite resin
www.indiandentalacademy.com
83. • Ideal properties of the core material
• High compressive and tensile strength.
• High modulus of elasticity (rigidity).
• High fracture toughness.
• Dimensional stability.
• Ease of manipulation.
• Short setting time.
• The ability to bond to both tooth and post.
• Biocompatibility.
• Inert (no corrosion).
• Natural tooth color, when indicated.
• Low plastic deformation.
• Low cost.
www.indiandentalacademy.com
84. Composite resin
• Composite resin cores are commonly used in the anterior
region. The final strength of these cores ranges from good to
excellent and they offer the option of preparation immediately
after placement
• They also lead to water sorption. Which results in core
breakdown. This expansion of composites due to water is a
potential concern due to generation of internal stresses.
www.indiandentalacademy.com
85. • . It is further seen that mechanical properties of composite
degrade with thermocycling and exposure of water.
www.indiandentalacademy.com
86. Amalgam
• The most commonly used core material with prefabricated
posts is amalgam. Amalgam is relatively easy to use, provides
a corrosion interface with the tooth, and has an excellent final
strength. Its coefficient of thermal expansion is almost double
of that of dentin and it is relatively stable in the presence of
water.
www.indiandentalacademy.com
87. • Amalgam is classified as to the shape of its particles.
• Spherical
• Spheroidal, or
• A blending of the two types known as an admix
www.indiandentalacademy.com
88. • . Fast setting amalgam is necessary if the practitioner wants to
prepare for the final restoration at the same appointment, and
the spherical alloys best meet this requirement.
• This type of amalgam gains strength rapidly and will allow
careful preparation after 15 to 20 minutes
www.indiandentalacademy.com
89. Glass Ionomer
• Increased use of glass ionomer has been reported recently to
restore the endodontically treated teeth
• The major drawback to their use is the question of adequate
strength to support the final restoration.
• They also require good isolation for placement. Which may
present a clinical challenge.
www.indiandentalacademy.com
90. • Their use is indicated primarily for blocking out small
undercut areas for crown preparation
www.indiandentalacademy.com
91. Cast Post and Core
• Cast post and core can be fabricated by direct and indirect
methods.
• Customs post and core patterns should be casted in Type III
and Type IV gold alloys or high noble alloys.
• They possess adequate strength and minimize corrosion.
• If a patient is not allergic to nickel, then nickel chromium
alloys should be used
www.indiandentalacademy.com
92. • nickel chromium alloys offer an acceptable strength
component, they also exhibit low resilience to loading and
may undergo corrosive change, making them less desirable as
gold substitutes.
• . It does not absorb water and has a coefficient of thermal
expansion very close to that of dentin
www.indiandentalacademy.com
93. • Advantages of the cast post and core include
• Preservation of the maximum tooth structure as the post is
fabricated to fit the radicular space.
• Provision of anti-rotational properties and
• Core retention, because the core is an inherent part of post and
does not need to be retained by the post.
www.indiandentalacademy.com
94. • Disadvantages include
• The appointments necessary to fabricate a pattern and then
seat the post.
• The decreased retention of the tapering design, and
• The wedging effect exerted on the root.
www.indiandentalacademy.com
95. ROLE OF THE FERRULE EFFECT
• The ferrule has been defined as a circumferential band to cast
metal at the margin of a crown which is placed on solid tooth
structure.
• A post and core in a pulpless tooth can transfer occlusal forces
intraradicularly with resultant predisposition to vertical
fracture of the root.
• “hugging action” of a subgingival collar of cast metal provided
extracoronal bracing that could prevent fracture of tooth
structure.
www.indiandentalacademy.com
97. • describe this 360-degree ring of cast restoration at least 2mm
apical to junction of the core and remaining tooth structure.
www.indiandentalacademy.com
98. CORROSION
• Recommendation have been made that the post and core, and
possibly the crown, be fabricated of the same metal as the
prolonged electrolytic reaction between dissimilar post and
core metals (stainless steel, silver, or brass posts reacting with
the tin in the amalgam core) may result in longitudinal and
oblique root fractures.
• The products of this reaction, deposit in the root canal, induce
volumetric changes and cause root fracture.
www.indiandentalacademy.com
99. CRITERIA FOR CAST POST AND CORE DESIGN
• maxillary incisors, requires locking notches or keyways
incorporated into the canal to resist rotational movements.
• The post should closely approximate the walls of the canals
without a wedging effect
• If the fit is too tight the forces of cementation may be
sufficient to fracture the root.
www.indiandentalacademy.com
101. • The cast post is roughened prior to cementation with a
sandpaper disk to remove the oxide layer of the casting and
increase the retention.
• The post is vented by flattening a small portion of the buccal
or lingual post along the length allow cement to escape
•
www.indiandentalacademy.com
102. PROCEDURES
• three stage operation.
1. removal of the root canal filing material to the appropriate
depth.
2. enlargement of the canal and
3. Preparation of the coronal tooth structure.
www.indiandentalacademy.com
103. Removal of the endodontic filling material
• It is recommended that the root canal system first be
completely obturated and then space made for a post.
• This will ensure that lateral canals are sealed.
www.indiandentalacademy.com
104. • There are two commonly used methods for removing gutta
percha –
1. with a warmed endodontic plugger
2. and with a rotary instrument
. Of these techniques, the warmed condenser is preferred
because it eliminates the possibility of the rotary instrument’s
inadvertently damaging the dentin.

105. • calculate the appropriate length of the post.
• Select and endodontic condenser large enough to hold heat
• Mark it at the appropriate length heat it, and place it in the
canal to soften the gutta percha.
• If the gutta percha is old and has lost its thermoplasticity, use a
rotary instrument,
• . Gates glidden drill. Para Post drill.
www.indiandentalacademy.com
106. • shape the canal as needed
• This is accomplished with endodontic hand instruments or a
low speed drill.
www.indiandentalacademy.com
107. Enlargement of the canal
• Prior to enlargement of the canal, a decision must be made
regarding the type of post system that will be used for
fabrication of the post and core
• Parallel sided prefabricated posts are recommended for
conservatively prepared root canals in teeth with roots of
circular cross section
• Excessively flared canals we use custom made posts
www.indiandentalacademy.com
108. For prefabricated posts
• Enlarge the canal one or two sizes with a drill, endodontic file,
or reamer that matches the configuration of the post.
• In the case of a threaded post, the appropriate drill is followed
by a tap.
• Use a prefabricated post that matches standard endodontic
instruments.
www.indiandentalacademy.com
109. For custom made posts
Use custom made posts in canals that have a non-circular
cross section or extreme taper.
Enlarging canals to conform to a preformed post may lead
to perforation.
Often very little preparation will be needed for a custom
made post.
However, undercuts within the canal should be removed
and some additional shaping usually is necessary.
• Be most careful on molars to avoid root perforation
www.indiandentalacademy.com
117. Preparation of the coronal tooth structure
• Ignore any missing tooth structure
• Remove all under cuts that would prevent withdrawal of the
pattern.
• Remove any unsupported tooth structure, but be careful to
preserve as much of the crown as possible.
• Be sure also that part of the crown is prepared perpendicular to
the post.
www.indiandentalacademy.com
118. • This will create a positive stop to prevent overseating and
possible splitting of the tooth. Similarly rotation of the post
must be prevented by preparing a flat surface parallel to the
post
• Complete the preparation by eliminating sharp angles and
establishing a smooth finish line.

119. Custom made posts
• A custom made post can be cast from a
• direct pattern or –with auto polymerising resin resin for single
root canals
• an indirect one. –for multi rooted tooth
www.indiandentalacademy.com
121. Core fabrication
• The core of a post-and –core restoration replaces missing
coronal tooth structure, and thereby forms the shape of the
tooth preparation
• . It can be shaped in resin or wax and added to the post pattern
before the assembly is cast in metal.
www.indiandentalacademy.com
122. Plastic filling materials
• The advantages of amalgam, glass ionomer or resins are that
• (1) maximum tooth structure can be conserved because
undercuts do not need to be removed, (2) treatment requires
one less patient visit,
• (3) there are fewer laboratory procedures, and
• (4) testing generally shows good strength characteristics,
possibly because of the good adaptation to tooth structure.
www.indiandentalacademy.com
123. Step-by-step procedure for amalgam
• Apply the rubber dam and remove gutta-percha-2to4mm
• Remove any existing restoration, undermined enamel, or
carious or weakened dentin
• if cusps are missing-adequate retention can be gained by
extending the amalgam into the root canals
• floor of the pulp chamber is thin-protect it from condensing
pressures with a cement base.
www.indiandentalacademy.com
124. • Condense the first increments of amalgam into the root canals
with an endodontic plugger
• Carve the alloy to shape. The impression can be made
immediately.
www.indiandentalacademy.com
125. Direct pattern for multirooted teeth
• A direct pattern can be used for multirooted posterior teeth,
although limited access may make the indirect approach easier
• . A single-piece core with auxiliary posts is used as opposed to
the multisection core recommended for indirect posterior cast
post-and cores
www.indiandentalacademy.com
126. • The core is cast directly onto the post of one canal.
• The procedure is simple, as long as smooth parallel sided or
tapered posts are used
1. Fit prefabricated posts into the prepared canals. One post is
roughened; the others are left smooth and lubricated.
2. Build up the core with auto polymerizing resin by the bead
technique.
3. Shape the core to final form with carbide finishing burs.
4. Grip the smooth lubricated posts with forceps and remove
them.
www.indiandentalacademy.com
127. 6. Remove, invest, and cast the core with the roughened single
post.
7. When this has been done, the holes for the auxiliary posts can
be refined with the appropriate twist drill.
8. After verifying the fit at try –in, cement the core and auxiliary
posts to place.
www.indiandentalacademy.com
128. Indirect pattern for posterior teeth
• Wax the custom-made posts as described previously.
• Build part of the core around the first post.
• Remove any undercuts.
• Wax additional sections and cast them.
• The use of dovetails to interlock the sections
www.indiandentalacademy.com
129. INVESTING AND CASTING
• A cast post-and –core should fit somewhat loosely in the
canal. A tight fit may cause root fracture. The casting should
be slightly undersized, which can be accomplished by
restricting expansion of the investment (e.g., by omitting the
usual ring liner or casting.

• When the mean retentive values were compared
between custom cast posts and parallel sided
serrated posts the diff was stastically significant
• The parallel sided serrated posts recorded
significantly higher retentive values than custom
cast posts
www.indiandentalacademy.com
133. SUMMARY AND CONCLUSION
• Although restoration of endodontically treated teeth has been
rationalized, information from controlled long term clinical
trials is still needed.
• As much tooth structure must be preserved as possible and
post and core is basically used to provide retention and support
for a cast restoration.
• There is not one post , core or final restoration that can be
used in all – clinical situations. So we have to learn with these
variables and understand the basic concepts of how to use
them to maximum advantage
