The effect of autogenous tooth roots for lateral alveolar ridge augmentation and staged implant placement (A Controlled clinical study and histological assessment)

Abstract

Successful implant therapy requires sufficient bone to be available for placing implants in the ideal prosthetically position and due to resorptive patterns after tooth extraction and need for achieving primary implant stability these clinical situations have been successfully treated with different bone augmentation approaches. Horizontal ridge augmentation of a deficient alveolar bone site is performed either simultaneously with implant placement, or with a staged approach prior to implant insertion. Autogenous bone graft had a high success rates exceeding 95%, however, limitations of autografts graft are the restricted donor sites, possible harvesting morbidity, reports of unpredictable resorption, and limited available bone volume had been reported for intraoral bone grafts. Tooth graft could be used as alternative to bone graft and it is devided to powder type which is supplied based on various sizes of particles, porosity between powders, blood wettability, osteoconduction, osteoinduction, and creeping substitution abilities The tooth block type has osteoinduction capacity via blood wettability, creeping substitution and space maintaining
