Mandibular Biological Drilling at Different Speeds for Dental Implant Placement

This randomized controlled clinical trial aims to evaluate the effect of different biological drilling speeds (50, 150, and 300 rpm) during implant osteotomy preparation in the mandible on marginal bone level changes and implant stability. Thirty-nine patients requiring a single dental implant in the mandible will be randomly allocated into three groups according to drilling speed. All implants will be placed using a biological drilling protocol without irrigation. Implant stability will be measured using resonance frequency analysis at implant placement and follow-up visits. Marginal bone levels will be evaluated radiographically using standardized periapical radiographs during the follow-up period up to 12 months. The study aims to determine whether different low-speed drilling protocols influence peri-implant bone remodeling and implant stability.
