Connective tissue grafting for primary closure of extraction sockets treated with an osteopromotive membrane technique: Surgical technique and clinical results

This article describes a grafting technique using connective tissue to perdictably obtain primary closure of extraction sockets treated with an osteopromotive membrane technique. This technique was used for a total of 24 sites in 22 consecutive patients to regenerate alveolar bone in severely damaged ridges and in conjunction with implants immediately installed into extraction sites. Two sites (8.3%) were complicated by premature membrane exposure that necessitated early removal. In the remaining 22 sites, membranes remained completely covered for a mean period of 23.75 weeks (SD = 8.21 weeks; range = 10 to 38 weeks).
