Two Techniques for Root Coverage With a Xenogeneic Collagen Matrix

Not Applicable

Completed

• Conditions: Gingival Recession
• Interventions: Device: root coverage comparing two techniques

• Registration Number: NCT02129504
• Lead Sponsor: University of Sao Paulo

Brief Summary

Gingival recessions are often successfully treated by coronally advanced flap technique (CAF) associated with subepithelial connective tissue grafts (SCTG). Currently the xenogeneic collagen matrix (CM) has been used as a substitute for SCTG associated with CAF technique for root coverage. CAF technique was not developed for use with CM and has shown limited results when applied to the CM. The aim of this study was to compare and show the benefits of the extended flap technique (EFT) compared to CAF technique using CM for root coverage.

Arm && Interventions

Group	Intervention	Description
coronal advanced technique	root coverage comparing two techniques	root coverage with the porcine collagen matrix using the coronal advanced technique (standard technique)
extended flap technique	root coverage comparing two techniques	root coverage with the porcine collagen matrix using the extended flap technique (new surgical technique)

Primary Outcome Measures

Name	Time	Method
Comparing changes for Root coverage measure (in millimeter) from baseline at 3, 6 and 12 months	Change from Baseline at 3, 6 and 12 months	At the mid-buccal point of the involved tooth, the gingival recession height was measure by the same operator, who was previously calibrated (intra-examiner calibration) using a digital paquimeter.
