Aim: This study was done to evaluate the bony changes around laser surface treated implants and sandblasted acid-etched surface treated implants installed in the mandible of completely edentulous patients.
Materials and methods: Evaluation of the marginal bone loss around implants was performed using image analysis software (Digora Optime, Soredex), bone resorption was measured as the distance between implant-abutment junction and the first implant-bone contact. Implant dimensions, width and length, were used for software calibration to compensate for radiographic magnification.
Marginal bone loss was determined in millimeters after 6, 9, 12 months from values at base line and averaged from mesial and distal aspect of each implant. After finishing the assessment phase, the collected data was collected and statistically analyzed.
Results: Results of this study showed that SLA group showed significant higher bone loss than Laser group at all observation times.
Conclusion: According to the discussion, and considering the limitations of the present study, it can be concluded that laser treated implant surfaces have significant marginal bone stability compared to SLA treated implant surfaces.
