Although the reconstruction of edentulous ridge with implants is commonly used, implantation is still a challenge in heavily absorbed alveolar ridge. Various surgical techniques including guided bone regeneration (GBR) using non resorbable barrier membrane or titanium mesh, onlay block grafting using intraosesous or extraosseous bone block, distraction osteogenesis and interpositional bone graft and ramus split bone technique have been utilized to overcome vertical bone deficiency.
However, these surgical techniques are known to have many disadvantages including technical difficulty, delayed surgical time, extended edentulous period and increased number of surgery. GBR using barrier membrane is also widely accepted for advanced ridge augmentation because surgical technique is relatively simple. However, collapse of bone graft placed on the defect in GBR procedure is known to cause poor bone regeneration.
This presentation presents simplified and innovative 3-dimensional ridge augmentation using tenting pole abutment and bone builder in order to prevent collapse of bone graft during healing period and reduce edentulous healing period, surgical time and number of surgery.
