Assessing the Change in Occlusal Vertical Dimension in Complete Dentures Prosthesis after Processing

Abstract

Introduction: Recording of jaw relations is the most important step in complete denture fabrication. One of the main reasons for complete denture failure is the error, in recording the correct vertical dimension of occlusion and its reproduction in final prosthesis. Methods: Thirty completely edentulous participants were selected for the study. The physiologic rest position of the mandible was used to record the vertical dimension of occlusion, and denture was fabricated following all the steps meticulously for all the study participants. A lateral cephalograph for each patient was shooted twice one with adjusted wax rims at determined the vertical dimension and another at denture insertion appointment. The comparative evaluation of both the cephalographs for the change in the angle made by two projection lines drawn by joining the orientation landmarks was carried out using the software of all the participants. Data were statistically analyzed using the Student's paired t-test, and software used in the analysis was the SPSS software version 22.0. Results: Statistically significant difference was observed in the mean occlusal vertical dimension (OVD) recorded at the Jaw relation stage with OVD in processed complete denture (t = 5.84, P = 0.000). Conclusion: The OVD recorded using the physiologic rest position method was found to be increased in the finished complete denture.
