Prosthodontic Treatment for Edentulous Patients.

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

Hanau combined the original nine factors and reduced them to five. In centric occlusion, b balanced occlusion: The force used in mastication by denture patients has been studied, and the findings are significant.

Hence, if the balance is not present, the bases could shift, tip or torque on their foundations during the eccentric movements and cause inflammation leading to accelerated bone resorption. In extreme working lateral position, contacts on both cusps incline, contact force are also directed outside the ridges [ Figure 1b ].

This article discusses about evolution of different concepts of occlusion and occlusal schemes in complete denture occlusion. Occlusal rehabilitation in complete denture fall into four occlusal concepts[ 4 ] Unbalanced articulation.


Complete Dentures – Hanau’s Quint | Foundation for Oral-facial Rehabilitation

Importance The concept was originally put forth to enhance the retention of complete dentures during mastication. Balanced occlusion in complete dentures is unique, as it does not occur with natural teeth. Gerodontic nutrition and dietary counseling for prosthodontic patients.

It appears, therefore, that the average complete denture wearer has barely adequate force for the work required during mastication. In centric occlusion, contact forces are directed toward the ridges [ Figure 4b ] and in right lateral working position, the occlusal forces are directed toward the lingual side of the lower ridge on the working side and toward the buccal side of the lower ridge on the balancing side depending on the inclination of second molar ramp [ Uqint 4c ].

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

Lang tooth forms or molds are of four types[ 347 ] Anatomic. Trapozzano concept[ 6 ] Trapozzano reviewed Hanau’s five hxnau and decided that only three factors were actually concerned in obtaining balanced occlusion. Occlusion as related to complete removable prosthodontics. J Prosthet Dent ; In right lateral position, c balanced occlusion: He eliminated the plane of orientation since quing location is highly variable within the available inner ridge space. J Indian Prosthodont Soc.


The force exerted in the incisor area dropped to nine pounds. Open in a separate window. In centric occlusion b Sear’s concept: In centric occlusion b Gysi’s concept: Jaw movements and tooth contacts are made, as the teeth of one jaw glide over the teeth of the opposing jaw.

Textbook of Complete Dentures. He mathematically charted the nine factors and listed the laws of balanced articulation in a series of 44 statements. Textbook of Complete Dentures. He also suggested that the occlusal plane can be located at various heights to favor a weaker ridge [ Figure 7 ]. Patient should be motivated to practice proper denture-wearing habits like not wearing dentures during the night.

Hanau’s quint

Application of miniaturised electronic devices to study of tooth contact in complete dentures, a progress report. Hudson have shown that complete denture teeth do contact at times during mastication. In centric occlusion c Pleasure’s concept: Brewer and Donald C.
