Abstract

Purpose: The present study was performed to compare the effect of two types of implant surface treatment (Laser Treatment versus Resorbable Blast Media (RBM)) on marginal bone height and bone density in two implant-supported mandibular complete dentures. Subjects and methods: Mandibular complete dentures were supported by two implants in nine patients who are qualified for treatment with two implants: laser-Lok implants and RBM implants. At baseline, 6 months, and 12 months follow-up, radiographic examination utilizing cone beam computed tomography (CBCT) was performed to evaluate marginal bone height and bone density. The ANOVA test was used to collect and analyze the data in order to compare the groups and examine the changes over time within each group. The significance level was set at P ≤ 0.05. Results: This study revealed a statistically significant increase in marginal bone loss in the RBM group compared to the laser group after 6 as well as 12 months. Regarding bone density, the laser group showed a statistically significant higher mean value compared to the RBM after 12 months. Conclusion: Laser-surface-treated implants show superior results compared to the use of RBM-surface-treated implants.
