In Vivo Evaluation Of Two Different Protocols For The Fabrication Of Implant-Supported Overdenture Prostheses

Background: This study focuses on the balanced distribution of relative masticatory pressure in two implant-supported overdenture rehabilitations and evaluates the effectiveness of the treatment protocol in achieving this. This study aims to compare, via a digital occlusal analyzer, the clinical effectiveness of the modified traditional protocol followed in two implant-supported mandibular overdenture rehabilitation with the traditional protocol. Methods: A total of 20 patients were included in the study and with the help of envelope drawing were randomly allocated into two groups: Group I (control/traditional protocol), Group II (test/modified traditional protocol). The distribution of the relative masticatory pressure, the change in masticatory pressure (Δp values) [including presence or absence of premature contacts and balanced/unbalanced pressure distribution] and treatment process management parameters were recorded utilizing Occlusence® for each patient, predelivery and at delivery. Data was statistically evaluated with t tests and chi-square tests, and significance level was set to α = 0.05. Results: No significant differences existed in masticatory pressure distribution and premature contacts between groups predelivery or at delivery. Predelivery, the test group showed significantly more balanced pressure than control’s (p0.370). In the management of the treatment process, the test group exhibited a statistically significant difference than control’s group. (p
