Abstract
BACKGROUND: Calcium phosphate (CaP)-coated surface showed enhanced contact osteogenesis around dental implant and finally accelerate osseointegration in early healing phase. PURPOSE: The aim of this randomized controlled trial was to compare the peri-implant marginal bone level around uncoated and CaP-coated sandblasted, large-grit, acid-etched (SLA) surface implants during the first year after placement. MATERIALS AND METHODS: This study was performed upon 34 patients with randomized and double-blinded design. Clinical and radiographic examinations were performed immediately after implant placement, at re-entry after 3 months, and after 12 months to evaluate the initial stability and change in the marginal bone level. The distance from the implant shoulder to the top of the bone-to-implant contact was defined as the marginal bone level, and its alteration was measured at 1 year after implant installation. RESULTS: None of the implants failed, and most of them showed a marginal bone loss of less than 1 mm. Small changes in the bone level were noted at all sites in the control and test groups, and there were no clinically significant differences in the changes in the marginal bone. CONCLUSION: Both CaP-coated and uncoated SLA surface implants showed comparably successful marginal bone stability without any complications during the first year after placement.
