Case examples In the radiographs of the first case we can see two materialscomparedaftersevenyears.Bothmaterials providevolumefordurabledentalimplants,butwhile the synthetic material is completely transformed to vital bone, the bovine material shows no signs of re- sorptionortransformation(Figs.1&2).Althoughthe bovine material is not resorbed in this case, we find a stabile situation for the implants. The second case shows the main complication as- sociated with bovine bone substitute. The bone graft isrejectedwithacoverofinflamedconnectivetissue. Clinically, the bone graft shows neither vitalisation nor connection with the host bone (Figs. 3 & 4). Highly resorbable alloplasts like pure ␤-tricalcium- phosphatedonotshowthesereactions.Cerasorb®M, a more than 99% pure ␤-tricalcium-phosphate with a polygonal, open cell structure and interconnecting pores allows a fast migration of osteoblasts and a complete transformation to endogenous, vital bone within six to nine months. As it has no biological his- tory and the manufacturing process guarantees the highest-possible absence of microbes and pyrogens, the use of the material is regarded as uncritical. In cell cultures the ␤-tricalcium-phosphate shows a significant advantage against bovine materials in colonisation with osteoblasts and an early biologisa- Fig. 5a Fig. 5b Fig. 5c Publish your expertise! research Survival of allogenic corticocancellous bone blocks case report Straightforward advanced complex in dental implantology industry Vestibular cortical stabilisation with bone graft implants international magazine of oral implantology issn 1868-3207 Vol. 17 • Issue 4/2016 42016 Become an author for implants—international magazine of oral implantology Please contact: Georg Isbaner · Editorial manager g.isbaner@oemus-media.de © Peshkova/Shutterstock.com AD Figs. 5a–c: Comparing test of different ceramic biomaterials for bone grafting with human osteo- blasts (SAOS-2).
