Acellular Dermal Matrix Versus Tenting Technique in Peri-implant Soft Tissue Augmentation and Crestal Bone Stability

Not Applicable

Completed

Interventions: Procedure: Soft Tissue Expansion using Tenting Technique
Procedure: Acellular Dermal Matrix

Brief Summary: This study looks at two ways to make gums thicker and bones stable around dental implants for people with thin gums. It compares two methods in 40 people: one method uses a special graft, and the other uses a technique called tenting. The goal is to see which method might work better for making the gums and bones around implants healthier. The check-ups are planned when the implant is put in and again after one year. The study focuses on how these methods are done without talking about what the results are.

Detailed Description: The study's protocol entails a randomized comparison between acellular dermal matrix grafting and the tenting technique, aimed at enhancing gum thickness and bone stability around dental implants in individuals with thin gum profiles. Forty participants are systematically assigned to one of the two methods under investigation. The study is structured to evaluate the interventions' potential in improving conditions conducive to the success of dental implants, specifically targeting soft tissue thickness and crestal bone level stability. The comprehensive investigation is designed to explore effective approaches for managing patients with particular soft tissue challenges, focusing on the clinical application and procedural aspects without presenting any results or conclusions.
