A Comparison of Side Access Mucosal Releasing Incision (SAMRI) and Sulcular Tunnel Access to Treat Gingival Recession. (NCT04179448)

A Prospective, Randomized Clinical Trial to Compare Side Access Mucosal Releasing Incision (SAMRI) and Sulcular Tunnel Access Procedures With Coronally Advanced Flap and Acellular Dermal Matrix (ADM) to Treat Gingival Recession.

๐Ÿ”ต Active, Not Recruiting Observational / Diagnostic ๐Ÿฉบ Clinical Procedure Protocol Sponsor: University of Alabama at Birmingham

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

This study will compare two incision designs to allow for coronal gingival/mucosal flap advancement and tissue augmentation with acellular dermal matrix (ADM) graft around teeth with gingival recession and a lack of adequate keratinized gingiva. The SAMRI technique described is a novel technique involving a simplified incision and suturing technique and to the investigators' knowledge, this is the first study that seeks to compare this technique to other techniques for differences in clinical outcomes (percentage root coverage, resultant tissue thickness, and width of keratinized tissue) and patient-centered outcomes (post-operative pain, swelling, changes in daily activities, and patient-assessed esthetics) in a controlled study.
