The Use of CoreBone Coral Particles vs. Cones for Preservation of Alveolar Bone

Normally, dentists do not graft the socket after extraction of teeth. When they do graft they use particulate graft devices. The purpose of this study is to examine whether coral particles of 300-450um in comparison to coral cones of 4-5mm wide and 8-10 mm long will preserve alveolar ridge of maxilla or mandible when grafted immediately after tooth extraction. The coral grafting devices are processed from Porites corals grown in aquariums, under controlled environment. The devices are cleansed and sterilized by gamma irradiation. The measurements during follow ups will be performed from CT x rays and measurements by caliber and models.The width and height measurements from follow up x rays and models. The study will be performed on 10 patients, that two parallel teeth are diagnosed to be extracted, in same patient.The data will be analysed for bone loss and compared to previous published studies. Also comparison between two devices will be performed.
