The aim of this study was to evaluate histomorphometrically and compare the efficiency of various bone graft material and autogenous tooth bone graft material which were used in sinus bone graft procedure. Subjects were the 24 patients who had treated with sinus bone graft using lateral approach from October 2007 to September 2009 at SNUBH. The average age was years. All cases was taken after 4month of procedure and divided into 3 groups according to bone graft material. Group 1: autogenous tooth bone graft material, Group 2: OrthoblastII(integra lifescience corp. Irvine, US)+Biocera(Osscotec, seoul, korea), group 3: DBX(Synthes, USA)+BioOss(Geistlich Pharm AG, Wolhusen, Switzerland). Total 37 implant placement area were included and evaluated(7 in group 1, 10 in group 2, 20 in group 3). Evaluation of new bone formation, ratio of woven bone to lamellar bone, ratio of new bone to graft material were performed on each tissue section. Kruskal-Wallis test was used for statistical analysis(SPSS Ver. 12.0, USA). New bone formation were in group 1, in group 2, in group 3. There were no statistical significant differences between each groups. Ratio of woven bone to lamella bone were in group 1, in group 2, in group 3. Ratio of new bone to graft material were in group 1, in group 2, in group 3. After 4 month of healing period, all group showed favorable new bone formation and around graft material and implant. Within limitation of our study, it is suggested that autogenous tooth bone graft material might be used as novel bone graft material for sinus bone graft.
