Horizontal Maxillary Ridge Augmentation With Sticky Bone Versus Collagen Membrane GBR

• [ Time Frame: ]

Guided bone regeneration (GBR) using bone graft and barrier membrane is a well-established technique for augmentation of atrophic alveolar ridges. There are many techniques for ridge augmentation involves the use of bone grafting materials, barrier membranes, possibly some tenting/fixation screws the stability of bone graft, space maintenance, angiogenesis, and tension free primary suture are essential for success.

• Device: Ridge augmentation with sticky bone and GBR
  Autogenous particulate bone will be harvested and a mixture of autogenous particulate and anorganic bovine bone mineral will be prepared at a ratio of 1:1 Venous blood will be drawn from patients' forearm and centrifuged at 2500 RPM/3 minutes and 4000 RPM/15 minutes to produce autologous fibrin glue and concentrated growth factors membrane, respectively Sticky bone will be prepared by adding autologous fibrin glue to the particulate mixture, placed onto the defect and covered by the prepared concentrated growth factors membrane For guided bone regeneration the particulate mixture will be placed onto the defect and covered by resorbable collagen membrane Periosteal releasing incision will be done to provide flap advancement for tension free closure Closure will be done using horizontal mattress and interrupted 4/0 polypropylene sutures
