Abstract
Establishing the correct occlusal plane after loss of natural teeth, is an arduous task. So a study was done with the following objective: To establish the occlusal plane in the edentulous patient and also to relate the occlusal plane to the maxillo-mandibular space length and height with the aid of cephalometrics. Materials and Methods: In this study the subjects were divided into two categories (a) Dentulous having Angle's class 1 occlusion (b) Edentulous with conventionally fabricated complete dentures. Lead foils were placed at predetermined positions on the mandibular dentures and then lateral cephalograms were taken. Cephalometric analysis was done and different angular measurements were recorded. After that depending upon average values of the height and length of the maxillary-mandibular space, all the subjects in each category were again divided into four groups. Results: Our results indicated that there is significant correlation between occluso-maxillary plane and maxillo-mandibular space length and height. Conclusion: This study can prove helpful for extensive oral rehabilitation cases.
