Official title
Impact of Mandibular Biological Drilling Speeds on Implant Stability and Osteogenic Potential of Autogenous Bone Particles: A Randomized Clinical Trial
Overview
This randomized clinical trial aims to evaluate the effect of different low-speed biological drilling protocols on implant stability and the osteogenic potential of autogenous bone particles collected during implant osteotomy. Patients requiring single dental implant placement in the mandible will be randomly assigned to different drilling speed protocols without irrigation. Implant stability will be measured clinically, while collected bone particles will be analyzed for osteogenic markers. The study aims to determine whether biological drilling improves implant stability and preserves the regenerative potential of autogenous bone.
Detailed description
Primary implant stability and the biological quality of bone particles generated during osteotomy are important determinants of successful osseointegration. Conventional implant site preparation typically uses high-speed drilling with irrigation to prevent thermal injury; however, this technique may compromise the biological quality and viability of harvested bone particles.
Low-speed biological drilling without irrigation has been proposed as an alternative technique that may preserve bone vitality, reduce thermal trauma, and allow collection of viable autogenous bone particles with regenerative potential.
This randomized clinical trial evaluates the influence of different mandibular drilling speeds (50 rpm, 150 rpm, and 300 rpm) during implant osteotomy on implant stability and on the osteogenic potential of the collected autogenous bone particles.
Implant stability will be assessed clinically, while the osteogenic potential of harvested bone particles will be evaluated using molecular biomarkers related to osteogenesis. The results of this study may provide evidence-based guidance for optimizing implant drilling protocols and improving bone regeneration potential in implant dentistry.
Interventions
- Procedure Implant osteotomy using biological drilling at 50 rpm without irrigation.
Implant osteotomy will be performed using low-speed biological drilling at 50 rpm without irrigation. Bone particles produced during drilling will be collected for evaluation of osteogenic potential. - Procedure Implant osteotomy using biological drilling at 150 rpm without irrigation.
Implant osteotomy will be performed using biological drilling at 150 rpm without irrigation. Autogenous bone particles generated during drilling will be collected and analyzed for osteogenic potential. - Procedure Implant osteotomy using biological drilling at 300 rpm without irrigation.
Implant osteotomy will be performed using biological drilling at 300 rpm without irrigation with collection of autogenous bone particles for laboratory analysis.
Primary outcome measures
- Implant Stability [Time frame: At time of insertion and 3 months postoperatively.]
Secondary outcome measures (1)
- Osteogenic Potential of Autogenous Bone Particles [Time frame: Immediately after bone particle collection and subsequent laboratory analysis.]
