Summary

Minimally invasive procedures with the tunnel technique have been suggested to decrease patient post-operative discomfort and morbidity in oral bone regeneration. In the ridge augmentation tunnel technique, crestal incision and the release of the connective tissue are avoided in order to enhance the blood supply of the flap. This approach preserves the blood circulation and does not damage the periosteum The purpose of this study is to evaluate the clinical outcome of a minimally invasive technique for maxillofacial horizontal bone augmentation . performed by using a collagen dermal matrix, deproteinized bovine bone and hyaluronic acid. Collagen matrix is inserted into a sub-periosteal tunnel using microsurgical instruments. Deproteinized bovine bone in a hyaluronic acid carrier are placed and inserted repeatedly into the pocket and absorbable suture is used to close the vertical incision.

Detailed description

Tunnel bone regeneration achieves treatment objectives using the least invasive surgical approach.The goal is to increase patient satisfaction, decrease post-operative discomfort and morbidity.Preservation of the integrity of the periosteum is a determining factor in reducing postoperative pain and improving wound vascularization. The present study value the clinical results of a subperiosteal minimally invasive ridge horizontal augmentation technique. The technique includes the use of a laparoscopic approach to deliver hyaluronic acid,xenograft and a dermal matrix into a subperiosteal pouch.

Conditions

• Bone Loss
• Implant Site Injury

Interventions

Type	Name	Description
PROCEDURE	bone and soft tissue augmentation	A vertical full-thickness incision in the mesial aspect of the defect ridge.Microsurgery instruments is subsequently use to carefully elevate the full thickness of the mucosa. Extreme caution must be exercised during these maneuvers to avoid tissue perforation and to maintain the integrity of the periosteum.An dermal matrix is place into the tunnel.A pouch is create between the bone and the membrane and the mixed bone chips and hyaluronic acid are inserted into the tunnel until the desirable ridge dimensions are obtained. Primary closure of the vertical incisions was achieved with single interrupted sutures.
