This document discusses the biomechanics of dental implants. It explains that osseointegration is the direct bonding of bone to implant surfaces. Studying biomechanics is important because implants must withstand stresses from chewing forces. Implant failures can occur early during healing or later under loading. Failures result from overloading, infection or inadequate bone. Biomechanics applies engineering principles to dental problems. Forces during chewing create both vertical and horizontal stresses on implants. Key biomechanical factors for implants are inclination, preload, material properties, design, and surrounding bone quality and quantity.

Scientific rationale and biomechanics in implantsMurtaza Kaderi
This document discusses the scientific rationale and biomechanics related to dental implants. It defines biomechanics as the relationship between biological behavior of oral structures and the physical influences of dental restorations. The document outlines different types of biomechanics and discusses various biomechanical concepts including forces, stresses, strains and how these impact dental implants and surrounding bone tissue. It also examines factors that influence loading on implants like force magnitude, direction, duration and position in the dental arch.
This document discusses biomechanics as it relates to implantology. It defines key biomechanical concepts such as force, stress, strain and their relationships. Forces on dental implants can come from biting or parafunctional habits and are made up of compressive, tensile and shear components. The magnitude of stress on implants is determined by the applied force and the cross-sectional area over which it is distributed. Maintaining low stress levels is important for long-term implant success and minimizing risk of failure. Biting forces on natural teeth can range from 100-2400 Newtons and impact loads present additional risk. Biomechanical principles guide optimal implant design and placement to ensure forces are properly dissipated.

Implant occlusion involves ensuring premature contacts are avoided through mutually protected articulation. The orientation of implant bodies and direction of loads influences bone mechanics, as does crown cusp angle, cantilevers, crown height, and occlusal contact positions. Proper implant crown contour is also important for implant-protective occlusion.
Occlusal Considerations For Implant Supported Prostheses Implant Protectes O...Mohammed Alshehri
Trauma from occlusion refers to pathological changes in the periodontium caused by excessive force from chewing muscles. While excessive force alone does not cause tissue breakdown, it may act as a co-factor in plaque-induced periodontal disease by enhancing the rate of progression. Proper treatment of plaque is important to arrest tissue destruction, even if occlusal trauma persists. Treating occlusal trauma alone through adjustment or splinting may reduce mobility but not stop further breakdown from untreated plaque.
This document summarizes key concepts regarding occlusion for implant-supported fixed dental prostheses. It notes that unlike natural teeth which have periodontal ligaments to absorb forces, implants lack this and forces are concentrated at the crestal bone. As such, implant occlusion schemes aim to reduce bending moments and distribute forces axially. Recommendations include using flat fossa and grooves, narrow occlusal tables, reduced cuspal inclines, stiffer materials, and avoiding excursive contacts to protect the implant and surrounding bone.
Dental implants require different biomechanical considerations from natural teeth. Also, with one of the criteria for long-term implant success being “occlusion,” it becomes imperative for the clinician to be well
versed with the different concepts when rehabilitating with an implant prosthesis.
This document discusses the evolution of dental implant loading protocols from the original Branemark protocol of a stress-free healing period of 3-6 months before loading to immediate and early loading protocols. It provides details on different loading protocols including Brånemark's protocol, progressive loading, non-submerged single stage protocol, immediate functional loading, immediate non-functional loading, early loading, delayed loading, and anticipated loading, focusing on factors like time interval, diet, occlusal material, occlusal contacts, and prosthesis design. The key factors identified for successful loading are minimizing micromotion at the bone-implant interface and ensuring adequate stability and occlusion.
This document discusses progressive bone loading for dental implants. It begins with an introduction and table of contents. Then it discusses concepts like bone density classifications, rationale for progressive loading based on studies showing bone adapts to stress over time. It outlines elements of progressive loading protocols including extended healing times based on bone density, use of provisional restorations to gradually load bone, and diet restrictions. Studies supporting progressive loading show less crestal bone loss and increased bone density around loaded implants. The conclusion is that progressive loading aims to strengthen bone and reduce risk of implant failure.

The document discusses the evolution of implant surfaces from original machined surfaces to micro-rough surfaces to nano-enhanced surfaces. Micro-rough surfaces allow for earlier loading through improved protein adsorption, fibrin clot retention, and accelerated cell adhesion and gene expression. Studies show bone deposited on micro-rough surfaces is harder and less subject to remodeling. Nano-enhanced surfaces further increase surface area for bone interlocking and protein adsorption. These surface improvements enable more predictable early and immediate loading of implants.
The document discusses occlusal considerations for implant-supported prostheses. It introduces various occlusal terminology and explores the significance of occlusion on osseointegrated implants. The document outlines the goals of implant protective occlusion (IPO), which aims to distribute occlusal forces appropriately to minimize stress on implants and surrounding bone. IPO principles include using thin articulating paper for initial adjustment, equalizing contacts under heavy bite forces, avoiding non-axial and offset loads, and designing the occlusion around the weakest component. The document also discusses factors like implant angulation, crown height, bone quality and the materials used for occlusal surfaces.
This document discusses immediate loading of dental implants. It defines various types of implant loading protocols, including immediate occlusal loading (within 48 hours), early loading (2 days to 3 months), conventional loading (3-6 months), and delayed loading (longer than conventional). Immediate loading provides advantages like improved aesthetics and function, but risks include failure if primary stability is inadequate. Factors that influence success include adequate bone quality and quantity, implant design/surface, number of implants used, and controlled occlusal forces. Careful patient selection and following guidelines for factors like implant spacing can allow for successful immediate loading.
There are several protocols for loading dental implants after surgery based on bone density and healing time requirements. Protocols include Brånemark's loading protocol, progressive loading, and immediate/early loading. The density of the bone where the implant is placed determines the appropriate loading protocol, as less dense bone requires more healing time before loading to allow for sufficient bone mineralization and strength. Progressive loading gradually increases stress on the implant over time to allow the bone to adapt, reducing risks of failure. It is particularly important for lower density bone which is weaker.

This document discusses occlusal schemes for implants, known as implant protective occlusion (IPO). IPO aims to reduce stress at the implant-bone interface through 14 considerations including eliminating premature contacts, positioning occlusal contacts over implant bodies, reducing cantilever lengths, and decreasing crown heights. The goals of IPO are to reduce force magnification, improve force direction, and increase the implant support area to promote implant longevity and success.

There are 3 main types of orthopedic appliances used to modify maxillary or mandibular growth: headgear, face masks, and chin cups. Headgears apply distal force to the maxilla via hooks on a facebow attached to maxillary molars. Proper force magnitude, direction (through the center of resistance), and duration are important to achieve skeletal changes. Face masks apply anterior force to the maxilla using elastic bands from a chin cup and/or forehead band. They are used to correct retrognathic maxillas. Chin cups provide anchorage for elastic traction from a reverse-pull face mask to protract the maxilla.
This document discusses implant biomechanics and treatment planning. It notes that implant overload can lead to bone loss and failure if excessive loads are placed on implants during treatment planning. Linear implant arrangements are less predictable than curvilinear arrangements, especially in posterior areas with heavy biting forces. The number of implants, their arrangement, angulation, length, diameter and the quality of surrounding bone all influence the load bearing capacity of implant restorations. Treatment plans must be designed to minimize non-axial forces and prevent implant overload.

ORTHOPEDIC APPLIANCES:
The appliance that produces skeletal changes by applying orthopaedic forces are known as “Orthopaedic appliance”.
‘Orthopaedic therapy' is aimed at the correction of skeletal imbalance with the correction of any dentoalveolar malocclusion being of less importance, in which little or no tooth movement is desired. Therefore, orthopedic forces are heavier (= 400 gm) when compared to orthodontic forces (50-100 gm).
Dental implant biomechanics, treatment planing, and prosthetic considerationsPalm Immsombatti
This document discusses biomechanical considerations for dental implants including load-bearing capacity, implant failure mechanisms, and treatment planning strategies. Key points include: osseointegrated implants can withstand anticipated loads if placed properly; excessive or nonaxial loads can lead to bone loss and failure; treatment planning aims to distribute loads across multiple implants placed in optimal positions and angles to avoid overload; and implant-retained overdentures are generally preferable to fixed prostheses for edentulous patients.

The document discusses dental implant design. It classifies implants as endosseous, subperiosteal, or transosseous, and describes common endosseous implant designs like ramus, pin, disk, platform, and cylindrical/root form concepts. Key considerations for implant design include withstanding forces in terms of magnitude, duration, type, direction and magnification. Surface area and thread geometry are also important to optimize load distribution to the bone. The crest and apical regions require special design attention to reduce stresses.
This document discusses immediate loading of dental implants. It defines immediate loading as loading an implant with a restoration within 2 weeks of placement. Immediate loading has benefits like eliminating a second surgery and allowing immediate function. However, it risks overloading the implant interface during bone healing. Factors that reduce this risk include increasing the implant surface area, decreasing occlusal forces, and using bone-friendly surfaces like hydroxyapatite. The document describes procedures for immediate loading in fully and partially edentulous patients, including using a provisional restoration made on the day of surgery or at a follow-up appointment. A soft diet is recommended during initial healing from immediate loading.

This document discusses several key points regarding dental implants:
1) Bone density and quality greatly impact implant success, with the highest success seen in the anterior mandible and lowest in the posterior maxilla due to poorer bone density.
2) Treatment planning considerations include implant placement based on available bone, with a minimum of 3 implants to replace missing posterior teeth in the maxilla.
3) Linear implant configurations are less stable than curved arrangements and more prone to overload from non-axial forces, particularly in low-density posterior areas.
Scientific rationale for dental implant carl e misch Meysam Aryam
This document discusses various aspects of dental implant design that influence bone loading and integration. It describes different implant body designs (e.g. cylinder, tapered), surface conditions (e.g. machined, rough), and thread designs (e.g. V-thread, square thread). Specific design features like thread pitch, depth, and crest module dimensions also impact load transfer and stress distribution. The ideal implant design provides adequate surface area for initial stability and load transfer while minimizing shear forces on the bone.

This document discusses dental implant abutments. It begins by defining an abutment as an intermediate component between the implant and restoration that is retained to the implant by a screw or locking taper. It then describes different types of abutments, including temporary abutments, those for screw or cement retention, straight or angled abutments, and stock vs custom abutments. The document discusses factors to consider for abutment selection such as interocclusal space, tissue height, and emergence profile. It also covers advantages and disadvantages of different abutment connections and materials.
Biomechanics of extra alveolar mini-implantsAshok Kumar
1) Extra-alveolar mini-implants placed in the infrazygomatic crest and mandibular buccal shelf areas provide effective anchorage for orthodontic tooth movement and treatment of complex malocclusions.
2) These mini-implants allow en masse retraction of the entire maxillary or mandibular arch in a single step using statically determinate biomechanics.
3) Retraction forces generated rotate the dental arch, causing intrusion of posterior teeth and extrusion of anterior teeth, which can assist in treating open bites and sagittal discrepancies.
This document discusses implant biomechanics and treatment planning considerations for restoring posterior quadrants. It notes that implant restorations must be designed to avoid overload, as excessive loads can lead to bone loss and implant failure over time. Key factors discussed include implant number, length, alignment relative to curves of Spee and Wilson, and linear versus curvilinear configurations. Curvilinear arrangements are emphasized as withstanding more load than linear arrangements due to greater cross-arch stabilization. Case examples demonstrate successful long-term outcomes and failures where biomechanics were not adequately considered.

Support in complete dentures /certified fixed orthodontic courses by Indian d...Indian dental academy
The document discusses support for complete dentures. It defines support as resistance to vertical forces from mastication and occlusion. Support is achieved initially through impression procedures that displace resilient tissues and record tissues in their loaded shape, and long term by directing forces toward tissues resistant to remodeling. The maxillary hard palate and mandibular buccal shelf provide primary support, while relief is needed for thin mucosa. Impression techniques aim to equalize pressure and minimize localized forces that could cause resorption.

11. Deformation and strain-
Load application may induce deformation of
both implant and surrounding tissues.
Biological tissue interprets deformation and
it’s manifestations and responds with
remodeling.
Stress and strain relationship-The closer the
modulus of elasticity of the implant to the
bone, less the likelihood of relative motion at
the tissue to implant interface.
www.indiandentalacademy.com
12. It is more important to decrease stress in
softer bone because of greater elastic
difference and lower ultimate strength.
www.indiandentalacademy.com
13. IMPACT LOAD
When two bodies collide in a very small
interval of time, relatively large reaction forces
develop.
Such collisions are called impacts.
Example : occlusal loads.
Cause deformation of implants and
surrounding tissue.
www.indiandentalacademy.com
14. Impact loads can be decreased by-
- Using acrylic teeth – Skalak (JPD 1983 : 49;
843-49).
- Weiss advocated fibrous tissue to implant
interface for shock absorption.
- Use of intramobile element to lower the
stiffness than rest of the implant.
www.indiandentalacademy.com
15. Misch advocates acrylic provisional with
progressive occlusal loading to improve
Bone-Implant interface before final
restoration.
www.indiandentalacademy.com
16. FORCE DELIVARY AND FAILURE MECHANISM
Moment loads
Moment of force about a point tends to
produce rotation or bending about that point.
M = Force x perpendicular distance , from
the point of interest.
Also called torque or torsional load.
www.indiandentalacademy.com
18. Clinical moment arms and crestal bone
loss
Six moments may develop about the 3
clinical coordinate axes .
Such loads induce microrotation and stress
concentration at the crest of alveolar ridge –
implant – bone interface and leads to crestal
bone loss
www.indiandentalacademy.com
19. Three clinical moment arms exist in implant
dentistry, minimization of each is necessary to
prevent failure.
www.indiandentalacademy.com
21. Occlusal height moment arm
Acts as a moment arm for a force components
directed along faciolingual and mesiodistal axis
www.indiandentalacademy.com
22. Cantilever length moment arm
Large moments from vertical axis force
component is seen in prosthetic
environments designed with cantilevered
extensions or offset loads from rigid implants
Distal cantilever should not extend 2.5 x the
A-P distance under ideal conditions
www.indiandentalacademy.com
24. Occlusal width moment arm
Wide occlusal tables increase moment
arm for any offset occlusal loads
Faciolingual rotation can be reduced by
narrow occlusal tables and adjusting
occlusion to provide more centric contact
www.indiandentalacademy.com
25. Scientific rationale for dental implant design
Biomechanical load management Is
dependent on two factors:
- Character of the applied force
- Functional surface area over which the
load is dissipated
www.indiandentalacademy.com
26. Character of forces applied to dental
implants
Forces applied to dental implants may be
characterized in terms of five distinct factors,
namely:
- Magnitude
- Duration
- Type
- Direction
- Magnification
www.indiandentalacademy.com
27. Force magnitude
Physiologic constraints on design:
- After sustained period of edentulism……
- Careful treatment planning & appropriate
implant design selection.
Influence on biomaterial selection:
- Many biocompatible materials unable to
sustain the magnitude of parafunctional loads
imposed on dental implant.
www.indiandentalacademy.com
28. Clinical implant design failures related to
choice of biomaterial and force magnitude.
www.indiandentalacademy.com
29. Force duration
Physiologic constraints on design-
-Ideally the forces duration while eating and
swallowing is ≈ 30 min ∕ day.
-Bruxers and other parafunctional habit pt.
Influence on implant body design-
- Materials that are subjected to repetitive
loads are at greater risk of fatigue failure.
www.indiandentalacademy.com
31. How the implant and abutment resists,
fracture from bending forces -----
www.indiandentalacademy.com
32. Force type
Physiological constraints on design :
- Bone is strongest in compressive > tensile >
shear
- Endosteal implants load bone - implant
interface in pure shear, unless surface
features are incorporated in design to
transform shear loads to more resistant force
types
www.indiandentalacademy.com
33. Influence on Implant body design :
- As angulation of load increases stress around
the implant Increases particularly in the
vulnerable crestal region
- As a result all implants are designed for
placement perpendicular to the occlusal
plane
- The face of thread or plateau can change the
direction of load from prosthesis to abutment
connection, to a different force direction at the
bone
www.indiandentalacademy.com
35. Force magnification
Extreme angulation and parafunctional habits
exceed the capability of the dental implant
design to withstand physiological load
Cantilever crown heights are levers and force
magnifiers
Careful treatment planning and multiple
implants are indicated in case of force
magnification
www.indiandentalacademy.com
36. Surface area
Anatomical constraints on surface area
optimization-
Bone vol : external architecture of bone
- Width is greater in the posterior region
- In general 6 to 8mm bone is available in the
anterior region and 4mm implant is used
- 7mm width is available in the posterior
region and 5mm implant is used
www.indiandentalacademy.com
37. - Therefore implant width may increase as
amount of force magnification increases from
anterior to posterior region.
- On the contrary bone height usually decreases
from anterior mandible, compared with the
anterior maxilla, the posterior mandible, to the
least in the edentulous posterior maxilla
- Hence as occlusal force increases bone height
and vol decreases
www.indiandentalacademy.com
38. Bone quality : internal architecture of bone
- four distinctly different bone density
classifications exist within the max and mand
- Greater failure rate has been documented in
porous bone compared with dense bone
- Additional implants or implants with greater
surface area have to be used in porous bone
www.indiandentalacademy.com
39. Functional surface area forces vs. Total
surface area-
For a given bone vol, implant surface area
must be optimized for functional loads
FSA: defined as the area that actively
serves to dissipate compressive and tensile
non shear loads through the I-B interface
and provides initial stability of the implant
following its surgical placement
www.indiandentalacademy.com
40. Functional thread surface area: portion of
the thread that participates in compressive
load transmission under the action of a axial
or near axial occlusal load
Total surface area : may Include a passive
area that does not participate in load transfer
Example : plasma spray coatings have 600%
more TSA but less than 30% is actually
exposed to the bone
www.indiandentalacademy.com
41. Since most stress to the I-B interface Is in the
crestal 1/2 of the implant, the crestal zone is
most important to distribute stresses
appropriately
Design variables in SA optimization
Implant macrogeometry
Implant width
Thread geometry
Implant length
Crest module configuration
Apical design considerationswww.indiandentalacademy.com
42. Implant macro geometry
Smooth sided cylindric implants provide
surgical ease however B-I interface is
subjected to significantly large shear
conditions
Smooth sided , tapered implants allows for a
component of compressive load to be
delivered to bone B-I interface depending on
the degree of taper
www.indiandentalacademy.com
43. Threaded implants with circular cross section
provide ease of surgical placement and allow
for >FSA optimization to transfer
compressive forces to the B-I interface
Also gives initial rigid fixation to limit micro
movement during healing
Smooth sided cylinder depends on coating
our micro structure for load transmission to
bone
www.indiandentalacademy.com
44. Implant width
Over the years implants have gradually
Increased in width
Scientific principle being > the width greater
the surface area
4mm implants have 33% > SA than 3mm
implants
Largest the width better the emergence
profile of the crownwww.indiandentalacademy.com
45. Crestal bone anatomy limits implants to <
5.5mm except in limited situations
Thus implant design innovations in crestal
region are required to provide increase in
FSA in this vulnerable region
www.indiandentalacademy.com
46. Thread geometry
FSA for unit length of the implant may be
modified by varying three geometric
parameters of implant
- Thread pitch
- Thread shape
- Thread depth
www.indiandentalacademy.com
47. Thread pitch is defined as the distance
measured parallel with its axis between
adjacent thread forms ( for V type threads ),
for the number of threads per unit length in
the same axial plane and on the same side of
the axis
Smaller / finer pitch : more threads on the
Implant body for given unit length and thus
greater surface area per unit length
www.indiandentalacademy.com
49. Thread shape:
• V shaped
• Square
• Buttress
- Dental implant applications dictates the
need for a thread shape optimized for a
long-term function ( load transmission )
under occlusal intrusive ( opposite of pull
out ) load directions
www.indiandentalacademy.com
51. The square thread provides an optimum
surface area for intrusive & compressive load
transmission
Shear loading most detrimental to bone
Shear force on V thread face its ten times
greater than on square thread
Buttress has similar shear component as V
under occlusal load
www.indiandentalacademy.com
52. Thread depth : refers to the distance between
the major and minor diameter of the thread
It may be varied for the length of the implant
to increase FSA in the region of highest
stress, example : crestal region
Reverse taper leads to a dramatic increase in
functional surface area at the crest of the
bone where stresses are highest
www.indiandentalacademy.com
54. Implant length
As length of the implant increases so does the
overall total surface area
Once I-B interface is formed excessively long
implants do not receive stress transmission to
the apical region and are not needed
D3, D4 bone in the posterior region have less
available bone height
www.indiandentalacademy.com
55. Nerve repositioning is cited as an acceptable
clinical treatment to facilitate longer implants
in the posterior mandible
Maxillary sinus grafts done for posterior
maxilla
Longer implants have been suggested to
provide greater stability under lateral loading
stress generated by lateral load can be
dissipated by implant in the range of 10 -15
mm length compared with implant of 20-30
mm length
www.indiandentalacademy.com
56. Crest module configuration
Crest module of implant body is the
transosteal region from implant body and is
characterized as a region of high
concentration of mechanical stress
Many crest modules have been designed to
reduce plaque accumulation once bone loss
has occurred
However design of crest module contributes
to crestal bone losswww.indiandentalacademy.com
59. Angulated crest module > 20° with surface
texture that increases bone contact causes
slightly beneficial cumbersome stress to
adjacent bone and decreased bone loss
Crest module should be slightly larger than
outer thread diameter
Crest module height is often 2 mm
A polished collar of minimum height should be
designed on the superior portion just below
the prosthesis platform (0.5 mm)
www.indiandentalacademy.com
60. Apical design considerations
Most root form implants are circular in cross
section
Around cross section does not resist shear
forces
As a result anti - rotational feature is
incorporated in apical region of implant body
www.indiandentalacademy.com
62. Another anti - rotational feature flat sides or
gross along the body or apical the region of
the implant body
When bone grows against flat end it is kept
under compression with rotational loads ,
thus apical end must be flat than pointed
www.indiandentalacademy.com
63. Surface coatings
Titanium plasma spray ( TPS )
- Implant body may be covered with a porous
coating , two materials commonly used for this
purpose titanium and hydroxyapatite
- Both are plasma sprayed on to implant body
- TPS increases B-I surface area and acts
similar to three dimensional surface rates may
stimulate adhesion osteogenesis
www.indiandentalacademy.com
64. - There is 600% increase in total surface area
- FSA increases by 25 to 30% which is
significant
- Improved initial fixation of implant is seen
specially in softer bone
Hydroxyapatite coatings :
- Similar roughness as TPS and increase FSA
- Direct bonding to bone which is of greater
strength
- Enhanced gap healing in hydroxyapatite
coating is seen
www.indiandentalacademy.com
65. Advantages of surface coatings:
- Increased surface area
- Increased roughness for initial stabilization
- Stronger B-I interface
Additional advantages of HA over TPS
- Faster healing of B-I interface
- Increased gap healing between B & HA
- Stronger interface than in TPS
- Less corrosion of metalwww.indiandentalacademy.com
66. Disadvantages of surface coatings :
- Coatings may be damaged when being
inserted in dense bone
- Increased surface roughness with the risk of
bacterial contamination when present above
bone
- HA : increased plaque retention when exposed
- Increased costs
