Horizontal Deficiecy in Maxillary Arches Clinical Trial
Official title:
Ridge Augmentation Using Autologous Concentrated Growth Factors (CGF) Enriched Bone Graft Matrix (Sticky Bone) Versus Guided Bone Regeneration Using Native Collagen Membrane in Horizontally Deficient Maxilla
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.
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.
