A study of stability of hydroxy-apatite coated implants and sandblasted, large-grit and acid-etched implants
Oral Biology Research
Purpose: The purpose of this study was to compare the stability of two types of surface treated implants. Materials and Methods: Participants in the experimental group were divided into two groups; the hydroxyapatite (HA)-coated implant group and the sandblasted with large grit and acid etched (SLA) implant group. For each group, implants were installed at various sites from anterior teeth to posterior teeth. The stability of each implant was then evaluated and compared. Stability of each
... t was evaluated using Osstell-mento and Periotest immediately after installation, and six weeks and 12 weeks after installation. Paired t-test and independent samples t-test were used in comparison and analysis of each measurement. Results: Measurements using Osstell-mento were found to increase with time in both the HA-coated implant and SLA implant groups. At 12 weeks after installation, only HA-coated implants showed statistical significance. However, using Periotest, no statistical significance was observed. In comparisonof HA-coated implants and SLA implants, no significant difference was observed between the two groups. Conclusion: HA-coated implants and SLA implantsinstalled at various sites with excellent initial stability showed successful osseointegration. With excellent initial stability, surface treatment of implants does not appear to have a signifi cant effect on the stability of the implant.
