Evaluation of Geistlich Fibro-Gide® in Comparison to CTG for the Treatment Around Implants
This double blind, randomized, parallel study evaluates the non-inferiority of Geistlich Fibro-Gide® in comparison to connective tissue graft for soft tissue volume augmentation around dental implants
A total sample size of 60 subjects (n=60) will be evaluated at 5 centers, by 6 Investigators with approximately 10-subjects per Investigator. Power analysis based on 80% power, past Thoma, Zeltner and González-Martin studies 1,2,3 and a one-sided confidence interval of 0.025, indicates that with a volume change standard deviation between 0.5 and 0.7 mm, 17-31 subjects are required per group (test and control), so 50-60 subjects are an acceptable estimate, with a preference for 60, given potential loss to long-term follow-up.
