Comparison of Surgical Techniques to Treat Isolated Gingival Recession in Mandibular Incisors: A Randomized Clinical Trial
Case Western Reserve University
Summary
The primary objective of this randomized clinical trial is to compare the mean root coverage achieved with Coronally Advanced Flap (CAF) + Connective Tissue Graft (CTG) (control) to Gingival Pedicle Split Thickness flap (GPST) + CTG (test) for the treatment of isolated gingival recession defects in mandibular incisors. The secondary objectives are to compare the percentage of complete root coverage and keratinized tissue gain between the two techniques.
Description
1. Research Scope: This study focuses on treatment of isolated gingival recession in mandibular incisors. Coronally advanced flap (CAF) with connective tissue graft (CTG) is the most predictable surgical technique for recession coverage (Chambrone and Tatakis 2015). However the early data indicate that CAF+CTG provides low predictability of root coverage of recessions in mandibular incisors (Zucchelli et al. 2014). We recently described a surgical technique called gingival pedicle split-thickness tunnel (GPST)+CTG. This technique entails a modified flap design to maximize recession coverage in…
