Trial Outcomes & Findings for Study of Root Coverage With Acellular Dermal Matrix: Puros® Dermis Versus Alloderm® (NCT NCT00881959)

NCT ID: NCT00881959

Last Updated: 2015-05-27

Results Overview

Non -inferiority of Dermis to Alloderm will be assessed by comparison of the average change (from the preoperative value) in gingival recession measured at 12 months between defects receiving Puros Dermis and those receiving Alloderm.

Participant Flow

Recruitment period was from 08 25 2009 to 04 24 2011. Subjects had a single non-adjacent Miller's class I or II gingival recession defect, greater than or equal to 2mm, located on the buccal aspect of the maxillary incisor, canine, or premolar. Subjects for this study were recruited from the PI's clinic.
