Abstract

Introduction. An enforcement of atrophic maxilla with biomaterials during sinus-lift surgery improves size and quality of alveolar bone. Radiological densitometric analysis can prove it. Within the study a density of bone was investigated and findings were compared with natural bone around the implants. Aim of the Study. Was to determine if density around the implant inserted with one stage sinus-lift operation using bone substitute materials increase and if that can be detected radiologically. Materials and Methods. Totally there were examined 22 patients where 64 implants were inserted in maxilla: 48 implants were inserted with one stage sinus-lift operation using bone substitute materials; represented study group. Sixteen implants were inserted in natural maxillary alveolar bone of the same patients, representing control group. The density of implant supporting tissue was measured with cone beam computed tomography and expressed in Hounsfield units (HU). The measurements were performed according to standardized pattern. Results. Densitometric measurements were higher in the study group than in the control group in all points, but statistically significant difference was observed in two measurement sites: buccally in sinus elevation area (BSM) (p=0.005) and palatinally in sinus elevation area (PSM) (p=0.0012), and corresponding areas in control group. Conclusions. Surgical elevation of maxillary sinus floor using calcium phosphate bone substitute materials resulted in higher optical density compared to natural bone. Mineralization of the bone, induced by the bone substitute materials, can be detected radiologically
