Clinical study of Bio-Oss powder and Bio-Oss collagen for site preservation during implantology].

To investigate the effect of Bio-Oss bone powder combined with Heal-All Oral repair membrane and Bio-Oss collagen on site preservation during implantology. A total of 26 cases were randomly divided into 2 groups. In Bio-Oss bone powder group (13 cases), the sockets were filled with Bio-Oss bone powder, covering with Heal-All Oral repair membrane on the surface. In Bio-Oss collagen group (13 cases), the sockets were filled with Bio-Oss collagen only. The changes in alveolar bone density，height，width and new bone contour were evaluated with cone-beam CT(CBCT) after site preservation. The data were analyzed with SPSS 17.0 software package. There was no significant difference in new bone contour between 2 groups(P>0.05). The changes in height, width and grey level of alveolar bone between the two groups were significantly different after 3 months of follow-up(P<0.01), but the curative effect was similar(P>0.05). There is no significant difference in the efficacy of site preservation between the two materials. However, the site preservation technique using collagen is simple, less invasive and less costly.
