[Study on bone volume harvested from the implant sites with different methods]

Area of Science:

• Oral Surgery
• Biomaterials Engineering
• Dental Implantology

Background:

• Autogenous bone grafting is crucial for successful dental implant procedures.
• Efficient harvesting of bone particles from implant sites is essential for bone augmentation.
• Optimizing bone harvesting techniques can improve graft availability and surgical outcomes.

Purpose of the Study:

• To compare the volume of autogenous bone particles harvested using different drilling techniques and implant systems.
• To identify the most advantageous method for collecting autogenous bone particles during implant surgery.

Main Methods:

• A simulated jaw bone model was used with Bicon, Bego, and Straumann implant systems.
• Two drilling techniques were evaluated: low-speed drilling without water and low-speed drilling with subsequent water irrigation.
• Bone particle volumes were measured after drying and compared between techniques, implant systems, and a specialized bone drill.

Main Results:

• Low-speed drilling without water irrigation yielded significantly higher bone volumes (3.3 to 7.0 times more) than drilling with water.
• The implant system (Bicon, Bego, Straumann) did not significantly affect bone volume when using the same water-irrigated drilling method.
• Bone harvested using the specialized bone drill was comparable to or slightly greater than that harvested with the tested implant systems.

Conclusions:

• Low-speed drilling without water irrigation is a more effective technique for harvesting autogenous bone particles.
• The choice of implant system does not influence bone harvest volume when employing the same drilling technique.
