Concepts of occlusion in prosthodontics: A literature review, part I

J Indian Prosthodont Soc. Some dentists believe there should be cusps on the teeth and that they must be in complete harmony with the dynamics of temporomandibular joint function.

Dentate status can hanaau diet, nutritional status, and general health. Cusp teeth have the inclines necessary for obtaining balanced occlusion but nearly always are used with a compensating curve.

[The Hanau quint].

Cuspless teeth are teeth designed without cuspal prominence quuint the occlusal surface. The concept of controlling posterior separation is an important goal for achieving a bilaterally balanced denture occlusion. So far, available research has not concluded a superior tooth form or occlusal scheme to satisfy the requirements of completely edentulous patients with respect to comfort, mastication, wuint, and esthetics.

The force used in mastication by denture patients has been studied, and the findings are hanqu. Support Center Support Center. Sears concept[ 5 ] 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.


The distal of the second molar can also be elevated to produce a compensating curve for protrusive balance [ Figure 4a ]. Importance The concept was originally put forth to enhance the retention of complete dentures during mastication.

Essentials of Complete Denture Prosthodontics. However, it will last for 17 min in a day. These conditions result in uneven force distribution and pathological changes in the underlying oral tissues, which will in turn results in poor patient comfort, destabilization suint occlusion, inefficient masticatory function, and esthetic problems.

Based on the interocclusal records, selective grinding is done to reduce the occlusal interferences to avoid deflective forces that are transmitted to the supporting structures. The balancing condylar guidance includes the working condyle Bennett movement, which may or may not affect lateral balance.

The greater the angle of the overbite vertical overlapthe greater is the separation in the anterior region and the posterior region regardless of the angle of the condylar path. Posterior separation compensation curve to balance the occlusion requires the introduction of the plane of orientation [ Figure 8 ].

The orientation of the occlusal plane, the incisal guidance, and the condylar guidance. Prosthodontic Treatment for Edentulous Patients.

Other dentists believed that the teeth should not have quont. The static relations in occlusion include centric occlusion, protrusive occlusion, right and left lateral occlusion.


Hanau’s quint – Oxford Reference

The lott concept[ 2367 ] He stated the laws as follows: Financial support and sponsorship Nil. Trapozzano concept[ 6 ] Trapozzano reviewed Hanau’s five hahau and decided quintt only three factors were actually concerned in obtaining balanced occlusion. J Indian Prosthodont Soc ; If it occurs in natural teeth, it is considered as a premature contact on the nonworking side and is considered to be pathologic.

Patient should be motivated to practice proper denture-wearing habits like not wearing dentures during the night.

Received Jun 7; Accepted Jun Resultant forces should be directed vertically and or lingually. 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 ].

Hudson have shown that complete denture teeth do contact at times during mastication. Open in a separate window. Other factors that affect chewing ability include mobile teeth, bone resorption, reduced sensory perceptions, and motor impairment. Although this force may vary in magnitude and direction, it must always be resisted by supporting tissues.
