Modified tunnel technique for management of gingival recession in esthetic zone using acellular dermal matrix versus connective tissue graft

Abstract

Gingival recession often results in major aesthetic problems. Further complains of increased root surface sensitivity and root caries could also be encountered. Numerous techniques have been described for the management of recession. The development of the tunnel technique represents an important esthetic advancement in managing recession defects. This study was performed to compare between the use of Acellular Dermal Matrix (ADM) and connective tissue graft (CTG) under a modified tunnel technique for management of gingival recession in the esthetic zone. Sixteen Miller class I and II recession defects were equally divided for treatment with the two donor materials. Plaque index (PI), gingival index (GI), gingival recession depth (GR), clinical attachment level (CAL) and keratinized tissue width (KTW) were assessed at base line and six months postoperatively. Both groups showed significant decrease in GR and gain in CAL slightly in favor to the ADM group. However no significant difference was recorded between the two groups in any of the studied parameters. Hence, ADM can be used as an alternative to CTG having the advantage of the absence of a secondary surgical site.
