Evaluation of Geistlich Fibro-Gide® + CAF in Comparison to CTG + CAF for the Treatment of Recession Defects at 6 Months — GFG-US-REC  

Gingival Recession Clinical Trial

Official title:
A Prospective, Randomized, Controlled, Double-blind, Multi-center Study to Assess Non-inferiority of Geistlich Fibro-Gide® in Comparison to Connective Tissue Graft for the Treatment of Recession Defects

Clinical Trial Summary

This double blind, randomized, split mouth study evaluates the non-inferiority of Geistlich Fibro-Gide® in comparison to connective tissue graft for the treatment of Miller Class I or II recession defects at 6 months post treatment.

Clinical Trial Description

This double blind, randomized, split mouth study evaluates the non-inferiority of Geistlich Fibro-Gide® in comparison to connective tissue graft for the treatment of Miller Class I or II recession defects at 6 months post treatment. A total sample size of 30 subjects (n=30) will be evaluated at 3 centers with 4 investigators. Power analysis based on 80% power and past McGuire/ Scheyer matched-pair defect recession coverage studies, with one-sided confidence interval 0.025, indicates that in order to detect a 12% difference in root coverage with ± 15% standard deviation a patient sample of 25 should be used . Given the multi-center nature of this study and the intention to follow patients long-term, with normal attrition, 30 subjects will ensure adequate long-term follow-up and provide a "power buffer" for any outcome differences that might be seen between centers. 30 Patients with Miller Class I or II recession defects on bilateral sites will be treated randomly with coronally advanced flap (CAF) in combination with either Geistlich Fibro-Gide (GFG =Test) on one side, and Connective Tissue Graft (CTG = Control) on the contralateral side of the mouth. Follow-up visits after visit 2 surgery will be conducted at week 1,2, 4,12 and 24 and in the long term after 1,3 and 5 years. ;
