THE USE OF CORTICAL HETEROLOGOUS SHEETS FOR SINUS LIFT BONE GRAFTING: A MODIFICATION OF TULASNE’S TECHNIQUE WITH 7-YEAR FOLLOW-UP

The use of an equine enzymatically deantigenated and partially demineralized cortical bone in sinus lift grafting procedure

 The use of heterologous cortical bone sheets effectively managed even large lacerations of the Schneiderian membrane and allowed for immediate stabilization of the heterologous bone granules. Average histomorphometric values for bone cores collected six months after grafting, at the time of implant placement, were: newly formed bone tissue, residual bone substitute, medullary spaces. At seven year follow-up, clinical and radiographic examination indicated that the use of the bone sheets preserved the regenerated bone volume. In conclusion, the use of heterologous cortical bone sheets in association with granular bone graft material enabled long-term stabilization of the graft material and effective management of intra-surgical complications.
