Feasibility of Alloplasts in Extraction-Socket and Sinus Augmentation Procedures

Thirty-eight patients (aged 25 to 74) requesting extraction-socket and sinus augmentation procedures (27 and 11 patients, respectively) prior to implant placement volunteered to participate in this case series protocol. Surgical sites were grafted with either biphasic calcium phosphate (BCP) + collagen (for extraction-socket augmentation) or BCP with a collagen barrier membrane (for maxillary sinus augmentation). All patients completed the 1-year postloading follow-up, which consisted of clinical and radiographic evaluations. No implants were lost, and both healthy soft tissue support and good radiographic evidence of supporting bone were found around implants. The result of this short-term evaluation of implants placed in areas grafted with alloplasts seemed to be favorable and promising.
