Background

Bone surgery involving cutting for shaping of bone tissue (osteotomy), and (osteoplasty) is notoriously difficult and requires precision and large mechanical forces to change the shape of mineralized bone or to remove bone tissue.

Traditionally, osteotomies, and osteoplasties are typically performed using manual chisels and other hand-held instruments, rotary drills, vibrating saws, and reciprocating saws. Manual instruments have proven unsatisfactory in their results, often due in part to the tendency of bone to shatter or split in an unpredictable manner. The limited use of saws is limited to straight cuts. Saws also produce excessive vibration and are difficult to operate and are non-selective for cutting various hard and soft tissue structures. Drilling has two disadvantages, namely:

1) the heat generated by drilling inhibits bone growth;

2) the vibration of the drill can cause imprecision in the shaping of the cut bone and, therefore, often damage the bone.
