Abstract:
PURPOSE: This study was designed to clarify the osseointegration of the titanium screw coated with CMP, in regard to the time schedule, through the characteristic of early osseointegration. MATERIALS AND METHODS: Mechanical, radiological and histomophometric measurements were performed in 28 rabbit tibial proximal metaphyseal cortical bone screws 6, 12, 26 and 52 weeks after surgery for the in vivo comparison of the osseointegration of titanium screws (3.75 mm diameter, 5 mm length) with different surface treatments: CMP coating group, with the sol-gel method (experimental group) and uncoated group (control group). RESULTS: 1. Radiology: There were no differences between the two groups without a radiolucent line or in regard to the time schedule. 2. Histology: There were no differences between the two groups without a fibrous tissue intervening surface or in regard to the time schedule. 3. Torque test: The test results for the CMP coated group were 1.5 times higher than those for the uncoated group, which was statistically meaningful, but there was no difference in regard to the time schedule. CONCLUSION: CMP coating is an option to increase the osseointegration of the titanium screw.
