ABSTRACT
Lack of sufficient bone is a main problem in implant treatment. Bone graft materials are potential solutions to this problem. Bioose is a grafting material that is routinely used for this purpose. In some studies autogenous demineralized dentin matrix [ADDM] has been used as bone substitute. The aim of this investigation was to compare the two grafting materials [ADDM and Biooss] on vertical bone augmentation in parietal bone of rabbits. Six white Newsland rabbit were used in this study. Two screws were inserted on the parietal bone of each rabbit in anteroposterior direction. Biooss powder was put around the anterior screw and ADDM particles around the posterior screw and both were covered with gutta percha membrane. The rabbits were sacrificed after 12 weeks and the specimens were sent for histological examination. Mann Whitney and paired T-tests were used to analyze the data. Range of bone height in Biooss group were between 0.1-2.1 and in ADDM group were 0.4-3.2 mm. Mean Bone height in Biooss group was 1.43 +/- 0.84 and in ADDM group was 1.4 +/- 1.03. Mann Whitney test showed no significant difference between the two groups in bone height. In this study the vertical bone augmentation in Biooss and ADDM groups were the same. Therefore, ADDM was an effective biomaterial for vertical bone augmentation in this study
