Abstract

Objective: The study was designed to evaluate the effect of laser surface treatment of implants on volumetric bone changes in implant retained overdentures through radiographic assessment over a period of one year post loading. Methods: Seven patients were selected from the out-patient clinic of the department of Oral and Maxillofacial prosthodontics, Faculty of Dentistry Ain Shams University where each patient received two implants in the intraforaminal region through guided surgery protocol. Each Patient received one laser-lok implant on one side of the mandible while the other side received an identical implant but with resorbable blast texturing surface treatment. Then each patient had a CBCT scan done at 0,6,12-month period following loading of the implants. The MIMCS software was then used to evaluate the volumetric bone changes in the peri-implant bone through the bone density readings. Statistical analysis was performed with paired t-test for intergroup comparisons and repeated measures ANOVA followed by Bonferroni post hoc test for intragroup comparisons. Results: The bone volume around the laser-lok implants showed a statistically significant higher values (2776.57±322.79) and lower percentage change rate (10.48±8.04) than the resorbable blast texturing group (2398.04±108.74) (19.37±0.20). Conclusion: The Laser-Lok implant increased the density of bone formed around the implant post-surgically and decreased the rate of volumetric bone loss around implant retained overdentures.
