Abstract
Purpose: The purpose of this study was to investigate the adequate measurement points and the standard value in the polygon for an analysis method using the traces of standardized, panoramic radiographs, designed as an image diagnostic method for complete denture prosthodontics.
Methods: The subjects consisted of young dentulous volunteers, and complete denture wearers immediatelyafter new denture insertion. We measured angular and linear measurements on the crucial parameters in prosthetic therapy, such as the occlusal vertical dimension and the occlusal plane, which were based on anatomical landmarks on the tracesof standardized panoramic radiographs. We determined the mean value of the youngdentulous subjects and the complete denture wearers (one-way ANOVA and multiple comparisons, statistically). Moreover, we prepared the polygon for each gender, based on the data of the complete denture wearers. And we assessed those parameters of the old and new dentures of one edentulous patient for each gender.
Results: The measurements showed significance between males and females of the young dentulous subjects and the complete denture wearers, and between the young dentulous subjects and the complete denture wearers for each gender. And the occlusal plane was more parallel to Camper's plane based on the inferior margin of tragus than the one based on the superior margin as the posterior referencepoints. Moreover, it was suggested that we could assess the occlusal plane and occlusal vertical dimension of edentulous patients by the polygon based on the data of complete denture wearers.
Conclusions: In this study, we improved the analysis method using the traces of standardized panoramic radiographs. And it was suggested that the polygon based on the data of complete denture wearers for each gender could be applied to assess the dentures of the edentulous patient.
