Background: Edentulism is a common clinical entity considered as an expected part of aging.The present study was conducted to compare conventional and diode laser to assess bone level in implant supported overdenture. Materials & Methods:40 implant sites was divided into two groupsie. Group I which was conventional second stage and group IIwas diode laser side. Measurements were made on mesial and distal sides using intraoral periapical radiographs and four sides (mesial, distal, labial, lingual) using CBCT scans in both groups. Results: There was non- significant difference in crestal bone level measured at baseline and at 24 weeks of loading between groups 1Aa and 2Aa, 1Ab and 2 Ab, 1ADa and 2ADa, 1ADb and 2ADb. There was non- significant difference in crestal bone level measured at baseline and at 24 weeks of loading between groups 1Ba and 2Ba, 1Bb and 2Bb, 1BDa and 2BDa, 1BDb and 2BDb. Conclusion: There was non- significant difference in crestal bone loss assessed using conventional and diode laser technique.
