简要总结
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.
详细描述
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.

Augmented tissue volume
时间窗: 7 month
The edentulous ridge will be scanned with an intraoral scan 3 times. First time: Initial situation. Second time: 5 months after regeneration. Third time: After implant placement. Will be evaluate the 3 scan in a cad-cam software to evaluate the ridge three-dimensional changes.
