What is the recommended speed for a motor-driven handpiece during a precise osteotomy technique?

The recommended speed for a motor-driven handpiece during a precise osteotomy technique is no greater than 20 revolutions per minute (RPM). This specific speed is optimal for maintaining control and precision during the procedure. At lower speeds, such as those cited in other choices, the handpiece allows for better tactile feedback and minimizes the risk of overheating the bone or causing damage to surrounding tissues.

Utilizing a speed of 20 RPM strikes a balance by providing enough power to perform the osteotomy effectively while still ensuring that the operator can maintain a high level of precision. Operating at higher speeds could lead to complications such as charring or necrosis of the bone due to excessive heat generation, which is particularly important when performing delicate procedures that require exactness. Lower speeds enhance safety and control, making 20 RPM the ideal choice for this context.
