Cortical Tenting Grafting Technique in the Severely Atrophic Alveolar Ridge for Implant Site Preparation
Alveolar ridge augmentation using autogenous block grafts is a predictable method to augment localized alveolar ridge defects for implant placement. Large atrophic
edentulous segments present a more challenging scenario in reconstruction,because there is a limited supply of
intraoral donor bone. Extraoral donor sites are an option, but present an obstacle to patient treatment acceptability because of increased costs and morbidity. The purpose of this case study was to evaluate the effectiveness of using particulate human mineralized allograft in combination with an intraoral cortical block graft, in a “tenting” fashion, to augment large intraoral alveolar ridge defects for implant placement.
