Gingival Recession Clinical Trial
Official title:
Collagen Matrix With Tunnel Technique Compared to CTG for the Treatment of Periodontal Recessions - Randomized Clinical Trial
The aim of this study is to compare the efficacy of dental root coverage using the tunnel
technique with connective tissue graft (CTG) and the same technique with collagen matrix for
treatment of multiple gingival recessions Miller Class I and II.
This study is a randomized-controlled clinical trial of 6 months duration.
According to the medical databases, there are limited randomized clinical trials comparing
xenogenic collagen matrix and CTG used with the tunnel technique. The collagen matrix is a
possible alternative to connective tissue graft.
The purpose of this clinical study is to compare short-term (3-6 months) outcomes of a root
coverage using the tunnel technique with the collagen matrix and the same technique with CTG
for the treatment of multiple recessions Miller class I and II.
Twenty eight patients are enrolled in the study. Patients in the test group are treated with
xenogenic collagen matrix using the tunnel technique whereas patients in the control group
with CTG. Clinical recordings are obtained at baseline and after 3 and 6 months. The
percentage of average recession coverage (ARC) is evaluated after 3 and 6 months after the
surgery.
