Is frequently overlooked or taken for granted in providing restorative dental treatment to patients.
Occlusion
In restorative treatment, the occlusion should be in harmony with the optimum condylar position, __________, which is an anteriorly, superiorly braced position along the articular eminence of the glenoid fossa, with the articular disc interposed between the condyle and eminence.
Centric relation
This position is the most orthopedically stable position, and because it is a result of activated elevator muscles, it is also the most musculoskeletally stable position.
Centric relation
A repeatable reference position for mounting casts in an articulator.
Centric relation
is a premature contact that occurs when the mandible closes with the condyles in their optimum position in the glenoid fossae. It will cause deflection of the mandible in a posterior, anterior, and/or lateral direction
Centric interference
May occur when there is contact between the maxillary and mandibular posterior teeth on the same side of the arches as the direction in which the mandible has moved.
Working interference
Is an occlusal contact between maxillary and mandibular teeth on the side of the arches opposite the direction in which the mandible has moved in a lateral excursion
Nonworking interference
A premature contact occurring between the mesial aspects of mandibular posterior teeth and the distal aspects of maxillary posterior teeth
Protrusive interference
Is based on the work of von Spee and Monson. It is a concept that is not used as frequently today as it has been in the past. It is largely a prosthodontics concept that dictates that a maximum number of teeth should contact in all excursive positions of the mandible. This is particularly useful in complete denture construction, in which contact on the nonworking side is important to prevent tipping of the denture.
Bilateral balanced occlusion
Also commonly known as group function, is a widely accepted and used method of tooth arrangement in restorative dental procedures today. This concept had its origin in the work of Schuyler and others who began to observe the destructive nature of tooth contact on the nonworking side. They concluded that in as much as cross-arch balance was not necessary in natural teeth, it would be best to eliminate all tooth contact on the nonworking side.
Unilateral balanced occlusion
Also known as canine-protected occlusion or organic occlusion
Mutually protected occlusion
The anterior teeth bear the entire load, and the posterior teeth are disoccluded in any excursive position of the mandible. The desired result is an absence of frictional wear.
The position of maximal intercuspation coincides with the optimal condylar position of the mandible.
This arrangement of the occlusion is probably the most widely accepted because of its ease of fabrication and greater tolerance by patients.
