Objective: To evaluate the effect of low grade soft laser clinically and radiographically on platform switching implants supporting mandibular complete over dentures.
Materials and methods: Ten edentulous subjects were eligible for inclusion. Two platform switching implants were placed in canine area of all patients. After three months, locator attachments remained connected to the implants, and the denture delivered with the retentive components incorporated in the denture base. Application of low grade laser for the right side implant only. At the follow-up examinations gingival index, pocket depth and marginal bone loss were evaluated at 6, 9 and 12 months.
Results: The sample of ten patients, with a mean age of 51 years was included in this study. All patients attended the 12-month follow-up. Non-statistically significant difference was found between the two sides regarding the gingival index, pocket depth and the marginal bone loss.
Conclusion: Within the limitation of this study the platform switching implant design ,and the application of low grade soft laser proved to be effective in preservation of alveolar crest bone height , gingival index and pocket depth..
