This document discusses the development of the concept of occlusion from early fictional and hypothetical periods to the current factual period. It outlines key figures and their contributions, such as Angle establishing occlusion as the basis of orthodontics. It describes Andrews' six keys to optimal occlusion and three occlusion philosophies, with gnathology focusing on occlusion as part of the functional masticatory system rather than just teeth. Determinants of occlusion include fixed, variable, vertical and horizontal factors.
The document discusses various aspects of normal occlusion and its characteristics. It defines normal occlusion as the absence of disease with functional adaptability of the masticatory system. Normal occlusion considers factors like occlusal contacts, tooth alignment, overbite/overjet, and the relationship between teeth and bones. It is a complex interaction between teeth, periodontal ligaments, jaws, temporomandibular joints, muscles and nerves. The document also discusses ideal occlusion, balanced occlusion, functional occlusion and other types of occlusion in detail.
This document discusses the concepts of occlusion from its early fictional and hypothetical development to becoming an established fact. It traces how occlusion was initially described as antagonism or meeting of teeth. Angle standardized the definition as the relation of inclined tooth planes in occlusion and cited examples like "Old Glory" skull. Factors determining tooth position include forces from lips, cheeks, tongue and occlusal contacts. Occlusion involves dynamic tooth contact positions as well as static postural resting positions and relationships with the temporomandibular joint. Terminologies like normal, ideal and traumatic occlusion are defined.

This document discusses different types of occlusion used in complete dentures, including bilateral balanced occlusion, monoplane occlusion, and lingualized occlusion. Bilateral balanced occlusion provides simultaneous contacts on both sides during jaw movements to evenly distribute occlusal forces. Monoplane occlusion uses flat, cuspless teeth without anterior or posterior contacts for simplified arrangement but lacks esthetics. Lingualized occlusion positions the large upper palatal cusp against the lower fossa for improved chewing efficiency. Factors like condylar guidance, incisal guidance, occlusal plane, and compensating curves must be considered to achieve balanced occlusion.

Concepts of dental occlusion and importance of six keys of occlusion in orth...Dr.Maulik patel
This document provides an overview of concepts of occlusion. It begins with introducing the importance of understanding occlusion in dentistry and orthodontics. It then discusses the development of occlusion concepts from fictional, hypothetical to factual periods. Key figures like Angle, Case and their contributions are explained.
Normal, ideal and traumatic occlusions are defined. Factors determining tooth position like forces from muscles and contacts are covered. Concepts like curves of Spee, Wilson and Monson are explained. Classifications of occlusion based on mandibular position and relationships to first molars are summarized. Finally, occlusion patterns like canine guidance and cusp-fossa are briefly described.
This chapter discusses the classification and etiology of malocclusion. Malocclusion can result from genetic factors, environmental factors, or a combination. Environmental influences include habits like digit-sucking and premature tooth loss from caries or trauma. Several commonly used classification systems are described, including Angle's classification (Classes I, II, III based on molar relationship), the British Standards Institute classification (based on incisor relationship), and the Index of Orthodontic Treatment Need (IOTN) which evaluates dental health and psychosocial impacts. The goal of orthodontic treatment is a functional occlusion without interference or pathology, though lack of an ideal occlusion may not cause long-term issues.
This document discusses various concepts of occlusion from different dental experts over time. It begins by outlining the contents to be covered, which include concepts of occlusion, optimal joint position, functional tooth contacts, normal vs ideal occlusion, occlusion contact patterns, and references. It then proceeds to summarize key aspects of different occlusion concepts proposed by experts like McCollum, Lauritzen, Guichet, Posselt, Schuyler, Beyron, Pankey Mann, Dawson, Gerber, and Ramfjord and Ash. Centric relation is also defined in detail from anatomical, conceptual and geometrical perspectives.

This document discusses centric jaw relation, including its definition, significance, and methods of recording. It begins by defining centric relation as the maxillomandibular relationship when the condyles are in their most superior and anterior position against the articular eminences, independently of tooth contact. The document then explores the changing definitions of centric relation over time and the anatomy of the temporomandibular joint as it relates to centric relation. It discusses the importance of centric relation in establishing harmony between centric occlusion and the jaw joints. Finally, it examines various static and functional methods for recording centric relation, such as chin point guidance, bimanual manipulation, and interocclusal records.
The human mandible can be related to the maxilla in several positions in the horizontal plane. Among these centric relation is a significant position, because of its usefulness in relating the dentulous and edentulous mandible to maxilla, where the teeth , muscles and temporomandibular joint function in harmony. It is a position of occluso-articular harmony.
This document discusses the evolution of occlusion concepts in dentistry. It begins with definitions of key occlusion terms and reviews various occlusion schemes that have been proposed over time, including lingualized occlusion, linear occlusion, and concepts put forth by Bonwill, Von Spee, Monson, and others. Requirements for artificial occlusion are outlined. The document emphasizes the differences between natural occlusion and artificial occlusion for complete dentures. Posterior tooth forms and concepts of occlusion are also examined.
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.
full mouth rehabilitation ppt including allmanjulikatyagi
The document discusses concepts and philosophies related to full mouth rehabilitation. It defines full mouth rehabilitation as restoring the form and function of the masticatory apparatus as close to normal as possible. Occlusion plays a key role in establishing synchronous harmony between teeth, TMJ, and muscles of mastication. The selection of the proper occlusal scheme is important for prosthetic rehabilitation. Various philosophies and concepts are discussed, including gnathological concept, mutually protected occlusion, group function, balanced occlusion, Pankey-Mann-Schuyler philosophy, and Hobo's twin table technique. Cusp shape factors, amount of disocclusion, and influences on disocclusion are also covered.

The document discusses various concepts of occlusion for fixed partial dentures, including bilaterally balanced occlusion, unilaterally balanced occlusion, and mutually protected occlusion. Bilaterally balanced occlusion aims for simultaneous contact on both sides but is difficult to achieve, while unilaterally balanced occlusion distributes forces to multiple teeth on the working side only. Mutually protected occlusion relies on anterior guidance to prevent posterior contact during excursive movements. The concepts vary in their distribution of forces and indications depending on a patient's needs.

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.

5. Concepts of occlusion
Three occlusal concepts:
The Gnathological
The Freedom-in-centric
European conceptual model
www.indiandentalacademy.com
6. THE GNATHOLOGICAL
CONCEPT
•Mid 1920’s McCollum.
Gnathology: exact science of
mandibular movement and resultant
occlusal contacts.
Instruments:
• Kinematic face bow, Gnathoscope
and Gnathograph
www.indiandentalacademy.com
7. Balanced occlusion:(complete
dentures)
“During functional excursions there
is multiple simultaneous contacts
present both on the working side
and on the balancing side”
Stallard and Stuart: organic or
organised occlusion.
-neglected that mastication is more
vertical than lateral.www.indiandentalacademy.com
8. ARNE G. LAURITZEN
Direction of occlusal stresses-long axis of
teeth.
Centric relation=centric occlusion
(condyles in uppermost and rearmost
position)
Simultaneous occlusal loads fall on as
great number of teeth.
Lateral excursion may be free.
Canine guided occlusion.
Group contact between upper and lower
anterior teeth during protrusive movement.www.indiandentalacademy.com
10. NILES GUICHET AND GNATHOLOGY
Optimal occlusion (1966)
Canine guided occlusion- biomechanics
Occlusion must be in harmony with the
mandibular movements of each patient.
Ganathograph and Pantograph.
Denar articulator.
www.indiandentalacademy.com
11. There is horizontal movement of the
mandible from the maximal
intercuspal position and teeth are
capable of standing that horizontal
stress in function .
(D’ Amicos)-canines - eight times
stress than on the 2nd
premolars.
www.indiandentalacademy.com
12. VISION OF TRANSOGRAPHIC CONCEPT
Page’s
Four principles:
1.Opening axis
2.Cranial plane
3.Bennett movement
4.Envelope of motion
1. Opening axis:12º to 15º of rotation.
Transverse hinge axis –reproducible.
www.indiandentalacademy.com
13. 2.Cranial planes:No translatory condyles,
so no practical support for horizontal
plane.
3.Bennett movement: such a movement is
because of mouth opening to 2
noncolinear axes, Page did not concede
to the existence of the Bennett side shift.
4. In the discussions conceding the
envelope of motion, when one takes the
motions to a narrow functional terminal
orbit, raised a great number of questions
in the oral rehabilitation.
www.indiandentalacademy.com
14. FREEDOM IN CENTRIC
Posselt was first
Functional occlusion- Ramfjord and Ash-
1970’s
Criteria are to attempt to eliminate the
need for neuromuscular adaptation.
According to this concept,
Maximum intercuspation and centric
relation are coincident but flat areas on the
depth of the fossae, on which opposing
www.indiandentalacademy.com
15. cusps occlude, will allow for a certain
degree of freedom in both centric and
eccentric movements without the guiding
influences of occlusal inclines.
Vertical dimension of occlusion in
maximum intercuspation and centric
relation might be the same when all the
interferences for closing in centric relation
are eliminated.
www.indiandentalacademy.com
18. OCCLUSAL CONCEPTS OF SCHUYLER
Correction of occlusal disharmonies in the
natural dentition and to the concepts of
freedom in centric and incisal guidance.
According to Schuyler,
Freedom in centric is a maxillomandibular
position where maximum intercuspation
and centric relation coincide to a certain
degree of freedom for eccentric excursions
without the influence of occlusal inclines.www.indiandentalacademy.com
19. Anteroposterior difference – 0.5 to 1
mm
Variation in centric relation recording –
not a point – area in relation to
horizontal plane.
Anterior guidance – Purpose: permit a
condylar motion without restrictions
along with the prevention of posterior
contacts, during lateral excursions
www.indiandentalacademy.com
21. BEYRON’S OCCLUSAL CONCEPTS
Based on functional convenience and
avoidance of discomfort
Most physiological inter-relationship
between morphology and function might
be the most natural one.
Neuromuscular mechanism- protects
teeth – excessive loads – protective
reflex- important role in mandibular
movement patterns.www.indiandentalacademy.com
22. PANKEY MANN PHILOSOPHY
Monson’s sphere (occlusal line and
plane) + Meyer’s concepts of a
functionally generated path
Pankey Mann Philosophy – oral
rehabilitation
Objectives:- optimal health, masticatory
efficiency, comfort and esthetics
Recently, Pankey Mann Schuyler concept
(based on group function)
www.indiandentalacademy.com
23. Stable and Static contacts - greatest
number of teeth
Long centric – Occlusal harmony with an
anterior slide between centric relation and
maximum intercuspation (1mm) and a
small amount of lateral freedom for
accommodation of the Bennett movement
on the horizontal plane.
Group function during lateral excursion
(working side)
Balancing side - No contacts
Protrusion – Immediate disocclusionwww.indiandentalacademy.com
25. DAWSON’S CONCEPT
Peter Dawson
Manipulation of the jaw in centric
relation (Bimanual technique)
Recording the border movements
(Modification of functionally
generated path technique)
www.indiandentalacademy.com
26. Anterior guidance:
Anterior teeth are more capable of
supporting stress than posteriors:
(a)Position of anteriors
(b)Higher density of bone
(c)Longer roots, better crown : root
ratio.
Theory of “Nutcracker”
www.indiandentalacademy.com
27. GERBER’S CONDYLAR
DISPLACEMENT THEORY
European concept
“ The normal or ideal occlusion was one
in which the teeth would be in maximum
intercuspation, with the condyles
centered in the articular surfaces in the
median and uppermost position. Any
deviation related to this mandibular
centralization constitutes a condylar
displacement.”
www.indiandentalacademy.com
29. RAMFJORD AND ASH CONCEPTS OF
OCCLUSION
Equilibrium between the different
components of masticatory system.
Freedom for condyle movement
The occlusal concept applied should
promote occlusal stability, does not
exceed the needs and finances of most
persons, is controlled by general clinician
and does not need a specialized
laboratory technician.
www.indiandentalacademy.com
32. Optimum orthopaedically stable
joint position
Centric relation, is the position
of the mandible when the
condyles are in an
orthopaedically stable position.
www.indiandentalacademy.com
33. Centric relation
1:The maxllomandibular 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
shapes of the articular eminences.This
position is independent of tooth contact.
This position is clinically discernible when
the mandible is directed superiorly and
anteriorly.
www.indiandentalacademy.com
34. It is restricted to a purely rotary
movement about the horizontal axis(GPT-
5).
2:The most retruded physiologic relation
of the mandible to the maxillae to and
from which the individual can make lateral
movements.It is a condition that can exist
at various degrees of jaw separation.It
occurs around the terminal hinge
axis(GPT-3).
www.indiandentalacademy.com
35. 3:The most retruded relation of he
mandible to the maxillae when the
condyles are in the most posterior
unstrained position in the glenoid fossae
from which lateral movement can be
made , at any given degree of jaw
separation(GPT-1).
4:The most posterior relation of the lower
to the upper jaw from which lateral
movement can be made at a given vertical
dimension(Boucher).
www.indiandentalacademy.com
36. 5:A maxilla to the mandible relationship in
which the condyles and the disks are
thought to be in the midmost,uppermost
position.The position has been difficult to
define anatomically but is determined
clinically by assessing when the jaw can
hinge on a fixed terminal axis (upto
25mm).It is clinically determined
relationship of the mandible to the maxilla
when the condyle–disk assemblies are
positioned in their most superior position in
the mandibular fossae and against the
distal slope of the articular eminence(ash).www.indiandentalacademy.com
37. 6:The relation of the mandible to the
maxillae when the condyles are in the
uppermost and the rearmost position in
the glenoid fossae.This position may not
be able to be recorded in the presence of
dysfunction of the masticatory system.
7: A clinically determined position of the
mandible placing both the condyles into
their anterior uppermost position.This can
be determined in patients without pain or
derangement in the TMJ (Ramfjord)
www.indiandentalacademy.com
39. Centric relation has been described in
three different ways: anatomically,
conceptually, and geometrically.
Anatomical:
It is the position of the mandible to the
maxilla, with the intra-articular disc in
place when the head of the condyle is
against the most superior part of the
distal facing incline of the glenoid
fossa.This can be paraphrased uppermost
and foremost.
www.indiandentalacademy.com
40. Conceptual:
It is that position of the mandible relative
to the maxilla, with the articular disc in
place, when the muscles that support the
mandible are in their most relaxed and
least strained position.
Geometrical:
It is the position of the mandible relative
to the maxilla,with the intra- articular disc
in place, when the head of the condyle is
in terminal hinge axis.www.indiandentalacademy.com
42. Optimum functional tooth contacts
Closure in CR
Creates an unstable occlusion
Neuromuscular system
Feed back muscles
Mandibular position
More stable occlusionwww.indiandentalacademy.com
47. Criteria for optimum functional
occlusion
Even and simultaneous contact of
all possible teeth when the
mandibular condyles are in their
most superoanterior position,
resting against the posterior slopes
of the articular eminences, with the
discs properly interposed.www.indiandentalacademy.com
51. Criteria for optimum functional
occlusion
First - Even and simultaneous
contact of all possible teeth +
centric relation
Second – each tooth should
contact in such a manner that the
forces of closure are directed
through the long axis of the teeth.www.indiandentalacademy.com
57. Postural considerations and
functional tooth contacts
Depends on head position
In the alert feeding position, as well as
in the normal upright position, the
posterior teeth should contact more
heavily than the anterior teeth
(mutually protected occlusion).
www.indiandentalacademy.com
58. Summary
1.When the mouth closes, the condyles are
in their most superoanterior
(Musculoskeletal stable) position, resting
on the posterior slopes of the articular
eminences with the discs properly
interposed. In this position there is even
and simultaneous contact of all posterior
teeth. The anterior teeth also contact but
more lightly than the posterior teeth.
www.indiandentalacademy.com
59. 2. All tooth contacts provide axial loading
of occlusal forces.
3. When the mandible moves into a
laterotrusive position, there are
adequate tooth-guided contacts on the
laterotrusive (working) side to
disocclude the mediotrusive
(nonworking) side immediately. The
most desirable guidance is provided by
the canines (canine guidance).
www.indiandentalacademy.com
60. 4. When the mandible moves into a
protrusive position, there are adequate
tooth-guided contacts on the anterior
teeth to disocclude all posterior teeth
immediately.
5. In the alert feeding position, posterior
tooth contacts are heavier than
anterior tooth contacts.
