The purpose of this study is to evaluate the new bone formation of sinus augmentation with using ICB (Irradiated Cancellous Bone & Marrow; Rockey Mountain Tissue Bank, Denver, Co) and MBCP (Micro-Macroporous Biphasic Calcium Phosphate;Biomatlante, France). Study population consisted of 4 patients with maxillary posterior edentulous dentition and ridge heights were less than 5 mm. ICB (Rockey Mountain Tissue Bank, Denver, Co) and MBCP (Biomatlante, France) is mixed with 50: 50. After 6 months, the bone biopsies were done with 2mm trephine bur from lateral window opening. Mean new bone formations were 26.84 %, the residual grafts were 4.92 and soft tissues were 67.98 %. The small number of biopsies did not permit analysis of statistical significance. The variability of individual patient factors do not permit definitive conclusions. The mixtures of ICB & MBCP were superior or comparable to another various bone alternative materials in new bone formation of sinus floor elevation.
