Study Overview
Brief Summary
Objective: To evaluate and compare the effect of two different attachment housing materials-Acetal Resin (Polyoxymethylene) versus conventional Nylon elastic caps-on marginal crestal bone loss around dental implants supporting a mandibular overdenture. It also evaluates peri-implant clinical tissue health by measuring pocket depth and the gingival bleeding index.
Detailed Description
Study Design & Timeline: A prospective, double-blind, randomized controlled clinical trial with a 1:1 allocation ratio. Clinical and radiographic outcomes will be evaluated at overdenture insertion (baseline), and at 6 and 12 months post-insertion.ethodology & Analysis: Pre-operative bone volume will be assessed via Cone Beam CT (CBCT). Crestal bone loss will be measured using the long cone parallel radiographic technique , while pocket depth and gingival bleeding will be measured using a William's graduated probing device. Data will undergo normality testing to determine the use of parametric (Independent t-test, Repeated Measures ANOVA) or non-parametric (Mann-Whitney, Friedman) statistical analyse
