J Prosthet Dent ; The concept was originally put forth to enhance the retention of complete dentures during mastication.

[The Hanau quint].

Occlusion and its relationship to the function of the stomatognathic system have been widely studied in dentistry since many decades. Prosthodontic Treatment for Edentulous Patients. Gerodontic nutrition and dietary counseling for prosthodontic patients. Open in a separate window. Though some authors argue that these contacts other than mastication are not likely to be made with any great deal of force, it is seen that many patients enjoy comfort only when the eccentric balance is present.

Jaw movements and tooth contacts are made, as the teeth of one jaw glide over the teeth of the opposing jaw. The compensating curve enables one to increase the effective height of the cusps without changing the form of the teeth. Usually, anatomic teeth are used to arrange teeth in balanced occlusion [Figure 10a — c ].

Part I and II of this articles series describe concepts and philosophies of occlusion in complete denture. In the right lateral position, the occlusal contact forces directed toward the ridge on the working side and toward the buccal side of the ridge on the balancing side [ Figure 3b ].


National Center for Biotechnology InformationU. Occlusion as related to complete removable prosthodontics. There has been much controversy about various concepts and the theories put forward to achieve occlusion. In right lateral position, c balanced occlusion: The orientation of the occlusal plane, the incisal guidance, and the condylar hahau.

Consequences of wearing the same complete dentures for a long period are attrition of artificial acrylic teeth and loss of occlusion. Hajau to the concept, the occlusal surface of the mandibular posterior teeth had been reduced to increase the stability of the dentures. In lateral mandibular movements, cusps contact bilaterally to enhance the stability of the dentures. The cuspal inclines should be developed so that the teeth can glide from a more centric occlusion to eccentric positions without interference and without the introduction of rotating or tipping forces.

Occlusal forces during chewing and swallowing as measured by sound transmission.

The static relations in occlusion include centric occlusion, protrusive occlusion, right and left lateral occlusion. Dynamic concept The dynamic concept of occlusion is primarily concerned with opening and closing movements involved in mastication. Hanauu triad of occlusion Click here to view. According to Brien R. A balanced articulation appears to be most appropriate because of tooth contacts observed during nonfunctional activities of patients.


The balancing condylar guidance includes the working condyle Bennett movement, which may or may not affect lateral balance. In centric occlusion, contact forces directed quijt the ridges according to the linear occlusal concept [ Figure 5a ].

These conditions result in uneven force distribution and pathological changes in the underlying oral tissues, which will in turn results in poor patient nanau, destabilization of occlusion, inefficient masticatory function, and esthetic problems.

Concepts of occlusion in prosthodontics: Dentate status can affect diet, nutritional status, and general health. This article discusses about evolution of different concepts of occlusion and occlusal schemes in complete denture occlusion. The laws of occlusion Lott Click here to view. Lea and Febiger; Pleasure rationalized that the occlusion should be of special design due to the instability of the lower denture.

In centric occlusion, nonanatomic teeth will exert contact forces toward the ridges [ Figure 3a ]. Sears in with his chewing members and in with channel teeth both were nonanatomic teeth developed a balanced occlusion by a curved occlusal plane anteroposteriorly and laterally or with the use of a second molar ramp. Cusp teeth have the inclines auint for obtaining balanced occlusion but nearly always are used with a compensating curve.
