The sheet sums up the results of two papers published on the International Journal of Oral & Maxillofacial Implants concerning the use of OX equine origin bone granules in maxillary sinus lift cases.
The first is a prospective randomized study conducted on 40 patients,treated alternatively with deproteinized bovine bone or with collagen-preserved, enzymatically treated equine bone.
The second is a retrospective study that involved 77 subjects, from whom 115 biopsies were taken2. All patients had undergone sinus lift with collagen- preserved.
The study showed how, already 3-5 months later, the quantity of newly formed bone was such as to allow implant insertion to be performed, and remained constant at longer biopsy taking times.
