In the present study, the effect of implant geometry on implant bone response was evaluated using two geometrically different implant types, i.e. screw type (St) and push-in type(Pi). Furthermore, the potential beneficial effect of an electrosprayed calcium phosphate (CaP) coating, either or not enriched with the osteoinductive growth factor TGF-beta1, on the osteogenic response was examined. MATERIAL AND METHODS: A total of 54 implants, divided into six groups (n=9), were inserted into the femoral condyles of nine goats. After an implantation period of 12 weeks, retrieved specimens were evaluated histologically and histomorphometrically. Measurements were statistically evaluated using SPSS 14.0 and analyzed using a linear regression model. RESULTS: With respect to implant design, St-implants showed an overall superior biological healing response compared with Pi-implants. Considering surface properties, the deposition of an electrosprayed CaP (2-3 microm) coating onto implants significantly increased the amount of bone-implant contact for both implant types. Additional enrichment of the CaP coating with the osteoinductive growth factor TGF-beta1 did not significantly affect peri-implant bone response. CONCLUSIONS: The results of this study indicate that a substantial improvement of the osteogenic response to titanium implants can be achieved by the deposition of an electrosprayed CaP coating. The enrichment of the coating with 1 microg TGF-beta1 has only a marginal effect
