Summary

This study was designed to assess peri-implant soft tissue health, volume and marginal stability at implants sites which presented small buccal bone dehiscences (\<3mm evaluated in a vertical direction) at the time of insertion. Patients will be then randomly allocated to receive grafting with connective tissue graft or guided bone regeneration and evaluated at 3 months after surgery and at 12 months of follow up after crown placement

Conditions

• Dental Implants

Interventions

Type	Name	Description
PROCEDURE	Connective tissue graft	Following implant placement, a connective tissue graft (CTG) will be harvested from the patient's palate using a standardized technique. The graft will be trimmed and adapted to the buccal aspect of the implant site and stabilized with sutures to increase peri-implant soft tissue thickness. Flap management will be performed to ensure passive adaptation and primary closure. Healing abutments will be placed.
PROCEDURE	horizontal guided bone regeneration	Following implant placement, guided bone regeneration (GBR) will be performed at the buccal aspect of the implant using a xenogeneic bone substitute to fill the dehiscence defect. The graft material will be covered with a resorbable collagen membrane, which will be stabilized to ensure defect containment. Flap advancement will be performed to obtain tension-free primary closure. Healing abutments will be placed according to the study protocol.
