Horizontal Deficiecy in Maxillary Arches
Conditions
Brief summary
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.
Detailed description
Common techniques introduced for horizontal ridge augmentation are Guided Bone Regeneration (GBR), there are many techniques for ridge augmentation involves the use of bone grafting materials, barrier membranes, possibly some tenting/fixation screws. For successful GBR, stability of bone graft, space maintenance, angiogenesis, and tension free primary suture are essential. Space maintenance with particulate bone graft should be provided during healing period. However particulate bone graft is easily migrated when grafted on the large horizontal bone defect. To reconstruct large bony defect or for the 3-dimensional ridge augmentation, bone tack on the collagen membrane or titanium mesh is required to contain particulate bone graft during healing but these procedures are surgically time consuming and technique sensitive. Sticky bone is biologically solidified bone graft which is entrapped in fibrin network. Sticky bone graft doesn't scatter because particulate bone powders are strongly interconnected each other by fibrin network.
Interventions
DEVICERidge 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
