An interventional study of Acetal Resin and nylon in Bone Loss and Pocket, Periodontal, sponsored by Future University in Egypt. Not yet recruiting. Open to male participants aged 40 Years to 60 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-06-24.
Sponsored by Future University in Egypt · Not applicable, Interventional, and Prevention
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.
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
