ABSTRACT

Autologous bone appears to be the most predictable and successful material available. The main problem concerning its use is its availability, but with autologous bone, there are no immunologic reactions or risks of disease transmission. The authors present a histological study of autologous bone used in ridge augmentation associated with bone lamina. Twenty patients participated in this study, and all gave their informed consent. In all patients, autologous bone was obtained during implant bed preparation in association with bone lamina in lateral and vertical ridge augmentation procedures.  After 12 months, a small biopsy of the regenerated tissues was carried out. Histologically, almost all particles of autologous bone were surrounded by newly formed bone; all particles had been surrounded by new bone or undergoing remodeling. In conclusion, we observed that autologous bone used in ridge augmentation procedures under bone lamina membranes presented excellent osteoconductive properties: all the particles were surrounded by newly formed bone.
