Occlusion refers to the relationship between opposing teeth when the jaws are closed. There are several types of complete denture occlusion including balanced, monoplane, and lingualized occlusion. Balanced occlusion involves simultaneous anterior and posterior tooth contacts on both sides during chewing and is unique to dentures but enhances stability. It requires a minimum of three contact points. Monoplane occlusion uses non-anatomic teeth without cuspal height for a simpler arrangement, while lingualized occlusion positions the maxillary lingual cusps against the mandibular teeth. Both have advantages and disadvantages related to function, forces, and appearance. Proper planning of occlusion is important for complete dentures.

When treating a patient with a removable partial denture, the natural and artificial teeth, both functionally and esthetically, must co-exist in a harmonious relationship.
Occlusal harmony between a removable partial denture and the remaining natural teeth is a major factor in preservation of the surrounding structures.
In removable partial dentures, because of the attachment of the denture to abutment teeth, occlusal stresses can be transmitted directly to the abutment teeth and other supporting structures, which results in sustained stresses that may be more damaging than those transient stresses found in complete dentures.

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.

Concepts of occlusion (Balanced and Non balanced Occlusion).
Unlike natural teeth, the artificial teeth act as a single unit. Hence there should be a minimum of three point contact (usually one anterior and two posterior) between the upper and lower teeth at any position of the mandible for even force distribution and stabilization of the denture.
All occlusal forms should have a tripod contact in centric relation. Balanced occlusion should have a tripod contact in eccentric relation.

Occlusal schemes in complete denture
1.
2. INTRODUCTION
OCCLUSION:
Occlude means to “CLOSE”
“The static relationship between the incising or masticating
surface of the maxillary or mandibular teeth or tooth
analogues” (GPT 8)
It is important to plan occlusal scheme prior to selection and
arrangement of artificial teeth
3.
4. Requirements of complete denture occlusion:
Cutting,Penetrating and shearing efficiency of occlusal surface
Minimum occlusal contact areas
Reduced posterior cusp height to control horizontal forces
Reduced buccolingual width of posterior teeth to decrease forces
transmitted to residual ridge
Stability of occlusion at centric relation position and in area forward
and lateral to it
Stability of occlusion in centric and eccentric relations
Balanced occlusal contacts
6. BALANCED OCCLUSION:-
“The bilateral,simultaneous,anterior and posterior
occlusal contact of teeth in centric and eccentric
positions” (GPT8)
It is not seen in the natural teeth,if it occur in natural teeth it is considered as
premature contact on non working side and considered as pathologic
It enhances the stability of denture
Balance in complete denture is unique and man made
7. Types of balanced occlusion
1. Unilateral lever balance
2. Unilateral occlusal balance
3. Bilateral occlusal balance
4. Protrusive occlusal balance
Unilateral lever balance:-
This is present when there is equilibrium of the base on its supporting
structures when a bolus of food is interposed between the teeth on
one side and a space exist between the teeth on the opposite side
8. Bilateral occlusal balance
• This is present when there is equilibrium on both sides of denture due to simultaneous
contact of teeth in centric and eccentric occlusion
• It requires a minimum of a three contacts for establishing a plane of equilibrium,the
more the contacts the more assured equilibrium
Unilateral occlusal balance
This is present when the occlusal surfaces of teeth on
one side articulate simulataneously as a group with a
smooth uninterrupted glide
9. Protrusive occlusal balance
• This is present when the mandible moves essentially forward and the occlusal
contacts are smooth and simultaneous in the posterior both on right and left
sides and on anterior teeth
• It is slightly different from bilateral balance in that it it requires a minimum of
three contacts (one on each side posteriorly and one anteriorly)
11. 1.Condylar Guidance
“The mechanical form located in the upper posterior region of an
articulator that controls movement of its mobile member (GPT8)”
Increase in condylar guidance will increase the jaw
separation during protrusion.this factor cannot be
modified,so in patients with steep condylar
guidance incisal guidance is decreased to prevent
the posterior jaw separation
12. 2.Incisal Guidance
“The influence of the contacting surfaces of the mandibular
and maxillary anterior teeth on mandibular movements”
(GPT8)
Incisal guide angle:-The angle formed between horizontal plane of occlusion and a line drawn in
the sagittal plane between the incisal edge of the maxillary an mandibular central incisors when
the teeth are in maximum intercuspation
It is determined by dentist during anterior try in
it should never be greater than the condylar guidance
13. 3.Plane of occlusion
“The average plane established by the incisal and occlusal surfaces
of the teeth.Generally it is not a plane but represents the planar
medium of the curvature of these surfaces” (GPT8)
It is established anteriorly by the height of the lower canine
and posteriorly by the height of the retromolar pad
14. 4.Compensating Curves
“The anteroposterior and lateral curvatures in the alignment of the
occluding surfaces and incisal edges of the artificial teeth that are
used to develop a balanced occlusion”
1.Anteroposterior compensating curve (curve of spee):-
“The anatomic curve established by the occlusal alignment of the teeth,as
projected onto medial plane,beginning with the cusp tip of the mandibular canine
and following the buccal cusp tip of premolar and molar teeth continuing through
the anterior border border of the mandibular ramus,ending with the anterior most
portion of the mandibular condyle” (GPT8)
Described by Ferdinand Graf Spee in 1890
15. • Signifance of curve of spee is when the patient move s his
mandible forward,the posterior teeth set on this curve will
continue remain in contact,thus avoiding disocclusion
16. 2.Lateral Compensating curves
1.Curve of Monson:-
”Curve of occlusion in which each cusp and incisal edge touches or
conforms to a segment of the surface of a sphere 8 inches in diameter with its
diameter with its centre in the region of glabella” (GPT8)
2.Reverse Curve or Anti monson curve:A cuve of occlusion that is convex
upwards and usually used to arrange the first premolars
17. 3.Curve of Wilson:
This curve that is convex downwards .the lower teeth are inclined
lingually giving prominence to buccal cusps and bringing them into heavy occlusal
contact with the upper buccal cusp during lateral movement on working side
4.Pleasure Curve:-
This combination of monson and anti monson curves .hence it is
not single curve but combination of curve
It was used for arranging non anatomic teeth in balanced occlusion
18. 5.Cuspal Inclination
“The angle made by the average slope of a cusp with the cusp plane
measured mesiodistal or buccolingually.also called as Cusp
Angle”(GPT)
It is an important factor that modify the effect of plane of
occlusion and compensating curves
Mesiodistal cusps are reduced to prevent the locking of cusps
19. Advantage:-
Bilateral simultaneous contact help to seat the denture in a stable position during
mastication,swallowing and maintain retention
Denture bases are stable even during bruxing activity
Cross arch balance
Disadvantage:-
It is difficult to achieve in mouths where an increased vertical incisor
overlap is present-class II Cases
It may tend to encourage lateral and protrusive grinding habits
A semi adjustable or fully adjustable articulator required
20. MONOPLANE OCCLUSION
“An occlusal arrangement where in the posterior teeth
have masticatory surfaces that lack any cuspal
height”(GPT8)
Occlusal arrangement using non anatomic teeth
Anterior teeth are arranged with an overjet of 2mm and no overbite
Monoplane occlusion can be balanced by placing balanced ramps distal to
second molar,it will improves horizontal stability of denture
Ramps
21. Advantage:-
They are more adaptable to unusual jaw relation such as class II and
class III relations
Easy to arrange teeth and less time consuming
They eliminate horizontal forces,more damaging than vertical forces
They accommodate better to the negative change in the ridge
height that occur with aging
Simple non adjustable articulator is sufficient
Disadvantage:-
No vertical Component to aid in shearing during mastication
Lack of positive intercupation
Poor Appearance
22. LINGUALIZED OCCLUSION
“This form of denture occlusion articulates the maxillary lingual cusps with
the mandibular occlusal surfaces in centric working and non working
mandibular positions” first described by S Howard Payne in 1941 (GPT8)
Lingualized occlusion can be a type of bilaterally balanced
occlusal cheme
Anatomic tooth are used in maxilla opposing a flat cusped or
shallow cusped mandibular tooth
Forces directed towards lingual side
Maxillary lingual cusp articulates with mandibular central
fossae
23. Advantage:-
Cusp form is more natural in appearance compared to non anatomic forms
Good penetration of bolus is possible this may reduce the lateral chewing component
Both anatomic and non anatomic tooth forms are retained
Simple technique
Can be used in Class II,Class III,IV And cross bite situations
Disadvantage:-
Wearing of maxillary lingual cusp or mandibular fossa
More challenging teeth arrangement than monoplane occlusion
