This document discusses various methods and materials for recording occlusal relationships during the fabrication of removable partial dentures. It describes techniques such as direct apposition of casts, using interocclusal records with posterior teeth remaining, recording the relationship with occlusal rims on record bases, and establishing the relationship entirely on occlusal rims. Ideal materials for occlusal registration include polyether elastomers and zinc oxide eugenol pastes due to their accuracy, stability, and minimal resistance to closure. The document also outlines the objectives and procedures for different registration methods.
The document discusses various aspects of recording jaw relations and establishing occlusion for removable partial dentures. It covers topics such as determining vertical dimension, recording horizontal jaw relations in centric relation and centric occlusion, methods for establishing the occlusal relationship like direct apposition of casts or using occlusion rims, selection and arrangement of prosthetic teeth, and establishing an occlusal scheme based on the number and position of remaining natural teeth. The goal is to create a harmonious occlusion that provides an efficient and comfortable masticatory mechanism for the patient.
This presentation aims to shed light on the various aspects of the mandibular movement in the TMJ which is like a hinge axis. the presentation contains brief history, the various schools of thought regarding the validity and accuracy of locating the hinge axis. it talks about the various types of facebows and the various anterior and posterior points for reference employed by the arbitrary facebows.
This document discusses different types of articulators used in prosthodontics. It begins by describing the basic parts of an articulator including the upper member, lower member, mounting plates, condylar analogues, condylar guidance, and incisal guide pin and table. It then discusses various individual articulators in more detail like the mean-value, Hanau, Whip-Mix, and Denar articulators. Key features and components of different Hanau articulator models are provided. Programming and mounting procedures are summarized briefly.
Centric relation relevance and role in complete denture construction NAMITHA ANAND
This document discusses centric relation, which refers to the relationship between the mandible and skull when the condyles are in their most superior position in the mandibular fossa against the posterior slope of the articular eminence. It has gone through various changing definitions but is now widely accepted to mean the anterior-superior position. Recording centric relation is important for complete denture construction as it provides proprioceptive feedback and acts as the starting point for occlusion. There are various passive and active methods to retrude the mandible as well as intraoral and extraoral graphic methods to record the position.

This document discusses concepts of complete denture occlusion including the differences between natural dentition and dentures, goals of denture occlusion, types of occlusion including bilateral balance and neutrocentric, and factors affecting occlusal balance. It also covers posterior tooth forms, balancing occlusion, and lingualized occlusion.
The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against developing mental illness and improve symptoms for those who already have a condition.
This document discusses establishing occlusion for removable partial dentures (RPDs). It notes that occlusion plays a major role in RPD success. Several methods are described for determining occlusion, including direct apposition of casts if enough teeth remain, making interocclusal records with wax if some teeth remain, and using occlusion rims on record bases if areas are edentulous. The goals of occlusion are outlined as occlusal harmony with remaining teeth, improving relationships if malocclusion exists, restoring vertical dimension, and correcting mandibular rotation from tooth loss. Desirable occlusal contacts include simultaneous bilateral contacts in centric occlusion and working side contacts for distal extension dentures.

Bite registration is a technique used to record the relationship between the upper and lower dental arches. There are various types of interocclusal records including centric relation records and eccentric records. Common materials used for bite registration include waxes, impression plaster, modeling compound, zinc oxide eugenol, acrylic resins, and elastomers. Newer digital techniques involve the use of scannable bite registration materials that can be directly scanned without a contrast medium. Proper bite registration is important for accurate mounting of dental casts during the fabrication of restorations.

1. There are several methods for establishing occlusion in removable partial dentures, including direct apposition of casts, interocclusal records with posterior teeth remaining, occlusal relations using occlusion rims on record bases, and jaw relation records made entirely on occlusion rims.
2. Interocclusal records involve using softened wax or other materials placed between teeth to record the jaw relationship. Occlusion rims are used when there are no contacts between natural teeth.
3. Establishing occlusion involves recording occlusal pathways over 24-48 hours by having the patient wear a registration. The registration is then used to arrange the artificial teeth to accept eccentric jaw movements.

Use of modified tooth forms in complete denture occlusion / dental implant...Indian dental academy
This document discusses dental occlusion concepts and philosophies for complete dentures. 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.

2. OCCLUSION
• The static relationship between the
incising or masticating surfaces of the
maxillary or mandibular teeth or tooth
analogues. (GPT-7)
www.indiandentalacademy.com
3. CENTRIC RELATION
• The maxillomandibular relationship in which the
condyles articulate with the thinnest avascular
portion of their respective disks with the complex
in the anterior-superior position against the
shape of the articular eminences. This position is
independent of tooth contact. This position is
clinically discernible when the mandible is
directed superior and anteriorly.it is restricted to
a purely rotary movement about a transverse
horizontal axis.(GPT-7)
www.indiandentalacademy.com
4. CENTRIC OCCLUSION
• The occlusion of opposing teeth when the
mandible is in centric relation.(GPT-7)
www.indiandentalacademy.com
5. MAXIMAL INTERCUSPAL
POSITION
• The complete intercuspation of the
opposing teeth independent of condylar
position, sometimes referred to as the best
fit of the teeth regardless of the condylar
position.(GPT-7)
www.indiandentalacademy.com
6. VERTICAL DIMENSION
• The distance between two selected
points, one on a fixed and one on a
movable member.
• OCCLUSAL VERTICAL DIMENSION : the
distance between two points when the
occluding members are in contact.
www.indiandentalacademy.com
7. • PHYSILOGICAL REST POSITION :the
mandibular position assumed when the
head is in an upright position and the
involved muscles, particularly the
elevators and depressor groups, are in
equilibrium and tonic contraction, the
condyles are in a neutral, unstrained
position.(GPT-7)
www.indiandentalacademy.com
8. OCCLUSAL REGISTRATION
• A registration of the positional relationship
of apposing teeth or arches; a record of
the positional relationship of the teeth or
jaws to each other.(GPT-7)
www.indiandentalacademy.com
9. OBJECTIVES:
To establish & maintain a harmonious
relationship with all oral structures & to
provide a masticatory apparatus which is
efficient, comfortable & esthetically
pleasing.
Necessary for distribution of functional
forces evenly as possible to all supporting
structures within their capability of
withstanding the stress.
www.indiandentalacademy.com
10. A harmonious occlusion contributes
materially to the control of damaging,
leverage induced stresses where as a
faculty occlusion compounds the
destructive forces.
www.indiandentalacademy.com
12. IDEAL REQUIREMENTS OF
BITE REGISTRATION
MATERIAL
Limited resistance before setting to avoid
displacing the teeth or mandible during
closure.
Rigid or resilient after setting.
Minimal dimensional change after setting.
Ideal recording of occlusal & incisal
surface of the teeth.
www.indiandentalacademy.com
13. Easy to manipulate.
No adverse effects on the tissues involved
in recording procedures.
Interocclusal record should be verifiable.
www.indiandentalacademy.com
14. IMPRESSION PLASTER
• Basically plaster of Paris in which
modifiers have been added. Modifiers
accelerates setting time &decreases
setting expansion.
www.indiandentalacademy.com
16. DISADVANTAGES:
Difficult to handle because the material is
unmanageable prior to setting.
The final interocclusal record is brittle.
www.indiandentalacademy.com
17. WAXES
• Thermoplastic waxes are frequently used
for interocclusal registration as records or
as a carrier for registration.
• Wax is widely accepted as an interocclusal
recording material.
www.indiandentalacademy.com
18. ADVANTAGES:
Easy to manipulate
DISADVANTAGES:
Inaccurate
Unstable
Inconsistent due to interference with
passive and active movements of
mandible.
www.indiandentalacademy.com
19. ZINC –OXIDE EUGENOL
PASTES
• Is an effective interocclusal registration
material
• ADVANTAGES
• Fluidity before setting.
• Fluidity is a critical quality of an
occlusal registration material because it
ensures minimal interference with
mandibular closure during record making
procedures.
www.indiandentalacademy.com
20. • Adhesion to its carrier
• Rigidity and inelasticity after final set
• Accuracy in recording occlusal and incisal
surfaces of the teeth
• High degree of repeatability
www.indiandentalacademy.com
21. DISADVANTAGES
• Lengthy setting
time
• Significant
brittleness
• The accuracy of
the registration
material may
surpass the
accuracy of the
casts, resulting in
improper fit. www.indiandentalacademy.com
22. SILICONE ELASTOMERS
Two types of silicone elastomers are
available as interocclusal registration
materials
• Condensation silicone
• Additional silicone
Currently, additional silicone has gained
acceptance because it is more stable than
condensation silicone
www.indiandentalacademy.com
23. ADVANTAGES:
• Accuracy
• Stability after setting
• Minimal resistance to closure
• Does not require a carrier
DISADVANTAGES:
• its resistance to compression of the set
material ,which contributes to difficulty in
seating of plaster cast
www.indiandentalacademy.com
24. POLYETHER ELASTOMERS
• These were introduced to dentistry in the
early 1970’s.
• Poly ether interocclusal registration
material consists of the basic impression
material augmented by plasticizers and
fillers
www.indiandentalacademy.com
25. ADVANTAGES:
• Accuracy
• Stability after polymerization and during
storage
• Fluidity and minimal resistance to closure
• Polyether can be used without a carrier
www.indiandentalacademy.com
27. DISADVANTAGES
• Resiliency and accuracy may exceed the
accuracy of the plaster casts. Both of
these factors can interfere with the
placement of the plaster cast into the
recording medium during mounting
procedures.
• The records are trimmed to remove
excess material and preserve only the
teeth indentations, avoiding distortions.
www.indiandentalacademy.com
28. ACRYLIC RESINS
• The most frequent application of acrylic
resins for interocclusal records is in the
fabrication of single –stop centric
occlusion records
ADVANTAGES
• Accurate
• Rigid after setting
www.indiandentalacademy.com
29. DISADVANTAGES:
• Dimensional instability of some
commercial formulations due to continued
polymerization resulting in shrinkage.
• The strength and rigidity of the material
can damage plaster cast and dies during
articulator mounting.
www.indiandentalacademy.com
30. STABILIZED BITE RIMS
• Stabilized rims may be constructed on the
replicas of the diagnostic cast. The rims
are transferred to the mouth and the
centric closure position recorded.
• Stabilized rims are indicated for the
positioning the cast prior to the formation
of the treatment plan and tooth
preparation.
www.indiandentalacademy.com
31. • LaDeane Fattore ,William F.malone and
associates conducted a study to compare the
clinical accuracy of various inter occlusal
recording materials (JPD 1984:51(2) 152-157) .
• THEY COMPARED
1.Two thickness pink base plate wax
2.Reinforced wax
3.Zinc -oxide eugenol paste
4.A modified ,non rigid poly ether recording
medium with a carrier
5.Poly ether without a carrier
www.indiandentalacademy.com
32. AND they concluded that
• Polyether inter occlusal recording medium
without a carrier was the most accurate
• Polyether and Zinc -oxide eugenol paste
with carriers were the next most accurate
recording mediums.
• Recording waxes were consistently
unreliable.
• Distortion occurred more frequently in a
vertical direction followed by an antero-
posterior direction.
www.indiandentalacademy.com
33. RECORDING OF OCCLUSAL
RELATIONSHIP
• It may vary from simple apposition of the
apposing casts by occluding sufficient
remaining natural teeth to recording of jaw
relationship in the same manner as for a
completely edentulous patient.
www.indiandentalacademy.com
34. • The horizontal jaw relation (planned
intercuspal position or centric relation) in
which restoration is to be fabricated should
be determined during diagnosis &
treatment planning.
• Mouth preparation should be based on this
determination including occlusal
adjustment of natural dentition wherever
indicated.
www.indiandentalacademy.com
35. METHODS OF RECORDING
OCCLUSION
Direct apposition of casts.
Interocclusal records with posterior teeth
remaining.
Occlusal relation using occlusal rims on
record bases.
Jaw relation made entirely on occlusion
rims.
Establishing occlusion by recording of
occlusal pathways.
www.indiandentalacademy.com
36. DIRECT APPOSITION OF CASTS
Also known as
“HAND
ARTICULATION”
coined by –
KROGH
POULSEN.
www.indiandentalacademy.com
37. INDICATIONS
• Sufficient opposing teeth that remain in
contact to make the existing jaw
relationship obvious.
• Only few teeth are to be replaced on short
denture bases.
• There is no evidence of occlusal
pathology.
www.indiandentalacademy.com
39. • The opposing
casts are occluded
by hand.
• It can be moved
slightly in various
lateral
anteroposterior
direction of
movement by
observation of
facets on
remaining teeth.
www.indiandentalacademy.com
40. • The occluding
casts are secured
together either
with wooden
sticks/wire nails &
sticky wax .
• They are
mounted in a
articulator.
www.indiandentalacademy.com
41. ADVANTAGES:
• Though there are limitation, yet it is better
than using an inaccurate record between
the remaining natural teeth.
• It eliminates the clinical appointment for
establishing occlusal relationship.
www.indiandentalacademy.com
42. LIMITATIONS
• The principle danger is this method may
perpetuate the existing vertical dimension
and any existing occlusal disharmony.
• So occlusal analysis and correction of any
occlusal disharmony should precede the
accepting of such a jaw relation.
www.indiandentalacademy.com
43. INTEROCCLUSAL RECORDS
WITH POSTERIOR TEETH
REMAINING
INDICATION:
It is the modification of the first
method and is used when sufficient teeth
remain to support the partial denture
(Kennedy class III or class IV) but the
relationship of opposing teeth does not
permit the occluding of cast by hand.
www.indiandentalacademy.com
45. PROCEDURE
• A uniformly
softened, metal
reinforced wafer of
base plate or set
up wax is placed
between the teeth
and the patient is
guided to close in
centric relation.
www.indiandentalacademy.com
46. • All excess wax
should be removed
with a sharp knife.
www.indiandentalacademy.com
47. • The wax is
removed and
chilled thoroughly.
It is again replaced
in mouth to correct
the distortion and
chilled again.
www.indiandentalacademy.com
48. • The wax record should be further corrected
with a bite registration paste to obtain a
more accurate and dimensionally stable
record.
• For this procedure the opposing surface of
teeth is coated with petroleum jelly for ease
of removal of record.
www.indiandentalacademy.com
49. • The impression
paste is applied to
both the side of the
wax record and the
patient is assisted
to close in centric
relation guided by
the wax record.
www.indiandentalacademy.com
50. • After the paste is
set, the record is
removed and
excess is trimmed
off.
www.indiandentalacademy.com
51. • Record is secured
to the maxillary
cast and then
mounted in an
articulator.
www.indiandentalacademy.com
52. ADVANTAGES
• Provides an accurate interocclusal record.
• If an intact opposing arch is present stone
can be directly poured into the record to
serve as a opposing cast.
• Acceptable procedure in fabricating
unilateral fixed partial denture.
www.indiandentalacademy.com
53. OCCLUSAL RELATIONALSHIPS
USING OCCLUSAL RIMS ON
RECORD BASES
INDICATION:
• When tooth supported edentulous space is
long.
• When opposing teeth do not meet.
www.indiandentalacademy.com
54. •When one or more distal extension areas
are present.
www.indiandentalacademy.com
56. • Occlusal rims are
constructed over
the record bases
by wax occlusion
rims or modeling
plastic occlusion
rims.
www.indiandentalacademy.com
57. • Vertical dimension
is corrected .
Occlusion rims are
reduced in height
just out of occlusal
contact. A single
stop is added to
maintain their
terminal position.
www.indiandentalacademy.com
58. • Bite registration is
made by injecting
the recording
medium in
between the two
occluding surfaces.
www.indiandentalacademy.com
59. • Patient should be
guided to the
centric position and
should be held in
position till the
material sets.
www.indiandentalacademy.com
60. • Completed record
is examined and it
is trimmed so that
only cusp tips and
indices remain.
Cast are then
mounted on the
articulator by using
the record.
www.indiandentalacademy.com
61. JAW RELATION RECORDS
MADE ENTIRELY ON OCCLUSAL
RIMS
• When no occlusal contact exists between
the teeth, such as when opposing
maxillary complete denture is to be made
concurrently with a mandibular partial
denture.
www.indiandentalacademy.com
62. • When few
remaining teeth do
not occlude and
will not influence
eccentric jaw
movement.
• When only anterior
teeth is present
www.indiandentalacademy.com
63. OBJECTIVES
• Static relation of the maxillary and
mandibular casts to each other should be
established in three planes. This is
accomplished clinically by establishing the
vertical ,centric and orientation
relationship.
www.indiandentalacademy.com
64. • Dynamic relationship of the two cast to be
established by protrusive and lateral
interocclusal records. These records can
be used to program the articulator to
simulate the natural movements of the
jaw.
www.indiandentalacademy.com
65. PROCEDURE
• Stable record bases and rims are required.
• Vertical dimension at rest and at occlusion
is established by means of
NISWONGER’s precepts.
• Centric relationship can be established by
direct interocclusal method or by stylus
tracing is used.
www.indiandentalacademy.com
66. • Eccentric records such as protrusive and
lateral records are made.
• Facebow transfer is made and the casts
are mounted on a semi adjustable
articulator.
• Articulator is programmed to simulate
natural movements of the lower jaw.
Desired occlusion is obtained.
www.indiandentalacademy.com
67. ADVANTAGES
• Method of choice when edentulous areas
are to be restored are opposed by
edentulous areas in a opposing jaw.
• Better method when the prosthesis is
opposed by a completely edentulous arch.
• Occlusion can be developed rather simply
for a typical partial denture, in a minimum
amount of time.
www.indiandentalacademy.com
68. • Does not require patient co-operation as
that needed for generating functional
pathway.
www.indiandentalacademy.com
69. LIMITATION
• Skill and care is necessary to obtain the
intraoral records, accuracy and
thoroughness with which they are used to
program the instrument.
www.indiandentalacademy.com
70. ESTABLISHING OCCLUSION BY
RECORDING OF OCCLUSAL
PATHWAYS
• FUNCTIONALLY
GENERATED PATH
METHOD.
• It is a dynamic record
of movement of
opposing tooth
surface.
www.indiandentalacademy.com
71. • Theory:
when the pathways each tooth opposed
to the edentulous space makes throughout
all functional movements of the mandible
are recorded, the artificial teeth may thus
be positioned and formed so that it will
remain in harmonious contact with its
antagonist all the times.
www.indiandentalacademy.com
72. CLINICAL PROCEDURE
• Stable acrylic resin record base with
compound hard wax or hard inlay wax
(purple) can be used to record the occlusal
pathways.
www.indiandentalacademy.com
73. • Occlusal rims is
constructed slightly
higher than the
occlusal plane so
that the natural
teeth are apart by
0.5 to 0.75mm.
www.indiandentalacademy.com
74. • Buccolingual width
of rim is several
millimeters wider
than that of
opposing teeth.
This is necessary
to record the full
range of motion.
www.indiandentalacademy.com
75. There are two methods of having the patient
grind the occlusal pathways.
• First method : the patient is instructed to
wear the occlusal rims continuously for 24
hrs excepting when eating and drinking
hot or chilled drinks.
He should be told to close the jaws
intermittently and grind the wax in all
possible jaw position.
www.indiandentalacademy.com
76. • The patient is asked to wear the
prosthesis overnight so that any
involuntary or bruxism contacts can be
records.
• The resulting pathway will be record of all
possible jaw movements and tooth
contacts.
www.indiandentalacademy.com
77. • Second method: is for the patient to create
the pathway directly under the supervision
of the dentist.
• Advantage: dentist is able to observe and
correct the movement the patient is
making.
• Disadvantage: atleast 30min of active
movement of the mandible is necessary.
www.indiandentalacademy.com
78. • The wax pattern is
boxed and poured
in improved stone
to provide
permanent record
of the generated
pathways.
www.indiandentalacademy.com
79. • The stone record is
mounted on a
articulator and the
artificial teeth are
set to contact the
record.
www.indiandentalacademy.com
80. ARTIFICIAL TEETH SET TO THE
GENERATED PATHWAY
• The incisal pin is opened 1mm before the
artificial teeth are positioned. This increase
in vertical dimension will be returned to
normal by selective grinding of the teeth.
• The selective grinding develops occlusal
anatomy of the denture teeth to conform to
the functionally generated stone path.
www.indiandentalacademy.com
81. • After the teeth are set in correct alignment
the incisal pin is returned to correct vertical
dimension of occlusion.
• Prussian blue dye is painted on to the
surface of generated pathway. Opening
and closing tapping movements are made
of stone path against the denture teeth.
www.indiandentalacademy.com
82. • Spots of dye are transferred to the denture
teeth. selective grinding is done till the
incisal tip touches the incisal table.
• The articulator is not moved into protrusive
and lateral movements because these
positions are incorporated in the pathway.
www.indiandentalacademy.com
83. ADVANTAGES
• The method makes unnecessary the
registration of inter occlusal records or a
face bow transfer and dispenses with the
need for a complicated articulator.
• Jaw movements and tooth pathways are
reproduced under more nearly functional
conditions than is the case when static
registration are transferred to an
instrument.
www.indiandentalacademy.com
84. LIMITATIONS
• Not indicated when the opposing occlusion
is provided by a complete denture or when
all the teeth is not present in the opposing
occlusion.
• Resistance may be encountered by the
mandible as the teeth shear through the
wax, which may serve to deflect the
mandible from its natural path.
www.indiandentalacademy.com
85. • The patient’s masticatory force and
direction may vary with foods of different
types. So the masticatory pattern of the
teeth during actual function differs from
that which they follow as they generate
pathways.
• Cannot be used to replace the anterior
teeth.
www.indiandentalacademy.com
86. ESTABLISHING JAW
RELATIONS FOR A
MANDIBULAR PARTIAL
DENTURE OPPOSING A
MAXILLARY COMPLETE
DENTURE
www.indiandentalacademy.com
87. • It is the most common situation.
• The maxillary denture may be already
present or it may be made concurrently
with the opposing partial denture.
www.indiandentalacademy.com
88. ESTABISHMENT OF JAW
RELATION WITH EXISTING
MAXILLARY COMPLETE
DENTURE
• If the existing maxillary denture is
satisfactory and has acceptable occlusal
plane, it can be treated as natural
dentition. Face bow transfer is made and
the cast obtained from the denture
impression is mounted on the articulator.
centric and eccentric records are made.
www.indiandentalacademy.com
89. • The stylus must be carefully removed from
the denture and attached to the same
palatal location on the stone
cast.Mandibular cast is orientated by
means of centric records.
• After processing the partial denture is
mounted against the complete denture for
occlusal correction. It will ensure more
accurate cuspal relationship.
www.indiandentalacademy.com
90. • When the mandibular partial denture
replaces all posterior teeth and the
anterior teeth are noninterfering, a central
bearing point tracer may be mounted in
the palate of maxillary denture and centric
relation recorded by means of an intraoral
stylus tracing against a stable mandibular
base.
www.indiandentalacademy.com
91. • If the relationship of maxillary posterior
teeth to the mandibular ridge is favorable
and the complete denture is stable
functionally generated method can be
used to obtain the records.
• If the maxillary denture has be made with
occlusal plane too low and improper
interarch relationship due to any
malposition of the natural teeth and if
those teeth has been lost ,repositioning of
the maxillary posterior teeth should be
done before the construction of the partial
denture. www.indiandentalacademy.com
92. MAXILLARY DENTURE TO BE
MADE CONCURRENTLY WITH
THE PARTIAL DENTURE
• If the mandibular partial denture will be
tooth supported it should be restored first
and so the maxillary complete denture is
made to occlude with an intact arch.
www.indiandentalacademy.com
93. • If the mandibular partial denture has one
or more distal extension bases, the
occlusion on both the arches should be
accomplished simultaneously.
• All mouth preparations and restorative
procedures need should be accomplished
on remaining natural teeth.
www.indiandentalacademy.com
94. • Occlusion should be established with
favorable tooth-to-ridge relationship,
optimal occlusal plane and cuspal
harmony between all occluding teeth.
• After try-in both dentures can be
processed at the same time or the
maxillary denture alone is fabricated and a
record is obtained using functionally
generated pathway and mandibular partial
denture teeth can be set to accommodate
the record. This gives good occlusal
harmony.
www.indiandentalacademy.com
95. FIXED PARTIAL DENTURE
AGAINST REMOVABLE PARTIAL
DENTURE
• In this situation fixed partial denture
should be fabricated and then the
construction of removable partial denture
should be made.
www.indiandentalacademy.com
96. • Better occlusion is possible if the occlusal
plane is restored with the abutment
restorations and pontics for the fixed
prosthesis and the teeth of removable
partial denture are then arranged to
articulate with them.
