The incisal guidance is usually obtained from the patient’s esthetic and phonetic requirements. Occlusion as related to complete removable prosthodontics.
In lateral mandibular movements, cusps contact bilaterally to enhance the stability of the dentures. Complete edentulism not only hampers the mastication, esthetics, but also affects the psychological well-being of the patient.
There has been much controversy about various concepts and the theories put forward to achieve occlusion. However, it became apparent that even a grain of food on the working side eliminates the balance on the nonworking side. Resultant forces should be directed vertically and or lingually.
Bernard Levin’s concept of the laws of articulation is quite similar to Lott’s, but he eliminated the plane of orientation [ Figure 9 ]. In centric occlusion, b balanced occlusion: Lea and Febiger; 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, phonetics, and esthetics. It appears, therefore, that the average complete denture wearer has barely adequate force for the work required during mastication.
National Center for Biotechnology InformationU. The lott concept[ 2367 ] He stated the laws as follows: In centric occlusion b Gysi’s concept: In a study of denture wearers with ages varying from 26 to 83 years, the average force in the molar and bicuspid area during mastication was 22—24 pounds.

Cusp teeth have the inclines necessary for obtaining balanced occlusion but nearly always are used with a compensating curve. Ganesh Kumarand Prasanna Karthik. In centric occlusion quin Pleasure’s concept: Nonanatomical teeth can be used with balancing ramps. Levin’s concept Click here to view.

Hence, arranging modified anatomic teeth in a semi-adjustable articulator, which can accept face bow transfer and horizontal and lateral condylar guidance records from which incisal guidance can be established for every individual patient. French concept[ 5 ] According to the concept, the occlusal surface of the mandibular posterior teeth had been reduced to qquint the stability of the dentures.
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 ].
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.
Occlusal forces during chewing and swallowing as measured by sound transmission. Related articles Articulation complete denture occlusion. Prosthodontic Treatment for Edentulous Patients. Occlusion and its relationship to the function of the stomatognathic system have been widely studied in dentistry since many decades. Mohamed IbrahimR. Ultimately, patient may not be able to wear dentures and will be diagnosed as prosthetically maladaptive.
Occlusal rehabilitation in complete denture fall into four occlusal concepts[ 4 ] Unbalanced articulation. In centric occlusion quinr Sear’s concept: Occlusion and its relationship to the function of the stomatognathic system have been widely studied in dentistry since many decades.
The condylar guidance is fixed and is recorded from the patient. According to the concept, the occlusal surface of the mandibular posterior teeth had been reduced to increase the stability of the dentures. Prosthodontic Treatment for Edentulous Patients. The orientation of the occlusal plane, the incisal guidance, and the condylar guidance.
Each case should be thoroughly evaluated based on the hard and soft tissue anatomy, resorption pattern, neuromuscular control, and the patient compliance. The concept was originally put forth to enhance the retention of complete dentures during mastication. Since then, several balanced and nonbalanced articulation concepts were proposed in the literature. Quinnt Prosthet Dent ; 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.
Monoplane or low cusp teeth must employ the use of a compensating curve. The laws of occlusion Lott Click here to view.
