The goal of this split-mouth randomized clinical trial study was to investigate the effect of using a laser on pain and discomfort following flapless dental implant surgery. It was hypothesized that laser did not have any impact on post-op pain. Therefore, the study aimed to compare pain and discomfort following flapless dental implant surgeries with or without a laser.
