Development of a prototype of dental implant from bovine bone
This study aims to develop an implant (screw + nut) manufactured by machining and with the raw bovine cortical bone mineral deproteinized (OBMD). The implant was developed for future clinical use in place of bone grafts in the techniques of lifting the maxillary sinus. We also evaluated the possible changes in the properties of OBMD, both as fat (G1) and sterilized (G2), through mechanical tests to measure the power of fixing screws. Dogs bred female Beagle Bangor were used in this experiment. Through a surgical approach, the tibia was exposed and it was machined with a diagonal orientation relative to the longitudinal axis of the bone, five internal threads bystanders. The implants were sterilized fully inserted into the bone. After an observation period of 120 days, the implants were removed, processed and evaluated histologically. Histological analysis showed clear neo-tissue formation on the implant-bone interface. In the mechanical and statistical analysis between groups G1 and G2 investigated were significant differences (p <0.05).
