Title

A simple and innovative surgical technique for the reconstruction of severely resorbed alveolar bone.

Abstract

Although implantation for the reconstruction of edentulous ridges is a common procedure, it remains a challenge when dealing with heavily absorbed alveolar ridges. Various surgical techniques, such as guided bone regeneration (GBR) using non-resorbable barrier membranes or titanium mesh, onlay block grafting using intraosseous or extraosseous bone blocks, distraction osteogenesis, interpositional bone graft, and ramus split bone techniques have been utilized to overcome vertical bone deficiency. However, these techniques have several disadvantages, including technical difficulty, extended surgical time, increased number of surgeries, and delayed edentulous healing period. GBR using barrier membranes is a relatively simple surgical technique widely accepted for advanced ridge augmentation. Nevertheless, the collapse of bone graft placed on the defect in GBR procedures is known to lead to poor bone regeneration. This presentation introduces a simplified and innovative 3-dimensional ridge augmentation technique that uses tenting pole abutments and bone builders to prevent bone graft collapse during the healing period. This technique reduces the edentulous healing period, surgical time, and number of surgeries.
