Details and patient eligibility

About

Microsurgical coronally advanced tunnel procedures using subepithelial connective tissue grafts (sCTG) are predictable for healing of multiple adjacent type 1 and 2 gingival recessions (RT1 and RT2). In order to reduce patient morbidity and enhance periodontal wound healing with sCTG can be used. The aim of this study is to compare the results of the modified tunneling technique with subepithelial connective tissue graft in gingival recessions placed with the inner side towards the flap cover graft and the outer side towards the flap cover graft.

Multiple adjacent recessions coverage with sCTG with inner side of the graft

Experimental group

Description:

Experimental: Multiple adjacent recessions coverage with subepithelial connective tissue graft.. A modified microsurgical tunnel technique. Initial sulcular incisions with a microsurgical blade are followed by a full-thickness buccal flap preparations till muco-gingival junction using the tunneling knives. Subsequently, the split-thickness preparation is extended into the mucosal tissue to gain sufficient flap mobility. The papillary regions are detached in their buccal aspects with the periosteum. The graft is inserted the inner side into the tunnel and stabilized with absorbable suspensory sutures. The buccal flap is advanced coronally and stabilized with non-absorbable suspensory sutures.

Device: The tunnel technique for root coverage with CTG with inner side of the graft
