Evaluation of Free Gingival Graft Timing

Evaluation of Free Gingival Graft Timing in Staged Guided Bone Regeneration: A Randomized Controlled Trial

This clinical trial aims to compare and evaluate the clinical outcomes between two distinct treatment sequences: free gingival graft surgery preceding guided bone regeneration and guided bone regeneration followed by free gingival graft.

Study Overview

• Status: Recruiting
• Conditions: Ridge Augmentation; Alveolar Mucosa
• Intervention / Treatment: Procedure: FGG Before GBR; Procedure: FGG after GBR

Detailed Description

This clinical trial aims to compare and evaluate the clinical outcomes between two distinct treatment sequences: free gingival graft surgery preceding guided bone regeneration and guided bone regeneration followed by free gingival graft. The primary objective is to assess the influence of the tissue graft timing on the outcomes of the guided bone regeneration. The secondary goal is to compare the complications that may arise following the two procedures before implant placement.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Volumetric outcome assessment	The volumetric outcomes of interest will be volume change in mm3 (Vol) and the mean distance between the surface/mean thickness of the reconstructed volume in mm.	Baseline to 12 months
Buccal soft tissue profile	The assessment involves measuring the profile of the buccal soft tissue from the implant shoulder.	Baseline to 12 months
