Abstract
For many years prosthodontists have been trying to find out the ideal location of Occlusal plane during complete denture fabrication. Though there is abundant literature which supports various methods to establish an artificial occlusal plane in edentulous patients, there is a lack of literature correlating which method establishes an occlusal plane that lies closest to the one occurring naturally. Hence this study was done to evaluate and establish a reliable method of occlusal plane determination in edentulous individuals and was carried out in 30 dentulous and 30 edentulous patients using lateral cephalograms. This study was performed in the Department of Prosthodontics, Tamilnadu Government Dental College and Hospital, Chennai. In this study conducted, 1. The angulation between the occlusal plane established in the edentulous patients using Hamular notch - Incisive Papilla plane and Frankfort Horizontal plane had closely resembled the angulation between the natural occlusal plane and Frankfort Horizontal plane in dentulous subjects. 2. The angulation between the occlusal plane established in the edentulous patients using the junction of middle and upper third of the retromolar pad as the reference and Frankfort Horizontal plane had also closely resembled the angulation between the natural occlusal plane and Frankfort Horizontal plane of the dentulous subjects next to the similarity obtained from the HIP as reference. 3. The angulation between the occlusal plane established in the edentulous patients using the Camper’s plane as the reference and Frankfort Horizontal plane showed a marked degree of variation from the corresponding angulation seen in the dentulous subjects and the two previous groups. 4. The angulation of occlusal plane and Frankfort Horizontal plane showed the minimum variation in dentulous subjects. Hence from the present study, it has been concluded that, Among the three methods used to establish an artificial occlusal plane, HIP plane is found to be more reliable reference plane in complete denture construction. • The occlusal plane established using the junction of the middle and upper third of the retromolar pad and the corner of the mouth as the reference can also be considered as a reliable guide to establish an artificial occlusal plane. • Camper’s plane shows a marked degree of variability as compared to the other two groups and it is not considered as a reliable reference plane to be used for establishing the occlusal plane during complete denture fabrication. • 9.3 is the average value of the angle between the occlusal plane and Frankfort Horizontal plane in the Indian population. • However, clinical judgement plays a major role in the assessment of occlusal plane in the edentulous patients. So this Geometrical analysis may be taken as a useful adjunct in establishing the occlusal plane.
