To minimize operative trauma in D3 bone during site preparation, which handpiece should be used for the final phase?

Using an ultra slow-handpiece with high torque during the final phase of site preparation in D3 bone is particularly effective because it allows for greater control and reduces the risk of overheating or over-aggressive drilling. At 15-30 rpm, this technique minimizes the operative trauma to the bone while still providing sufficient torque to ensure that the osteotomy is completed efficiently.

The low-speed and high-torque aspect of this approach helps to preserve the integrity of the surrounding bone structure, which is critical in D3 bone that is typically more fragile and less dense than higher quality bone. This method fosters better healing and integration of the dental implant by minimizing thermal damage and preserving blood supply in the area.

This choice is favored in clinical practice when preparing sites in compromised bone because it aligns well with the principles of bone preservation and patient safety during dental procedures.
