Pages 399-411, Language: EnglishDodge, John R. / Greenwell, Henry / Drisko, Connie / Wittwer, John W. / Yancey, John / Rebitski, GeorgeTwelve patients with 2 Miller Class I or II buccal recession defects measuring = 3.0 mm were treated using the principles of guided tissue regeneration and followed for 12 months. The effectiveness of a polylactide (Guidor) resorbable membrane (GA sites) was compared to a combination treatment of polylactide membrane plus polyglactin root-lining mesh (Vicryl) and demineralized freeze-dried bone allograft (DFDBA) (GVB sites) designed to enhance cell migration and bone regeneration. There was 90% mean soft tissue root coverage for the GVB sites and 78% for the GA sites. The mean osseous dehiscence area coverage with hard tissue was 75% for GVB sites and 30% for GA sites.
