Abstract: An osteotome includes a connector, a first arm, a second arm, a third arm, a fourth arm and a cutting head. A coordinate system has an X axis, a Y axis, and a Z axis. The X axis, the Y axis and the Z axis are perpendicular to each other and intersect at an original point. The connector extends along the Y axis. The first arm, extending along the Y axis, connects to the second arm, extending along the plane with the X and Y axes. An angle between the first and second arms is within a range between 125 to 145 degrees. The third and fourth arms respectively extend along the Z axis and the X axis. The cutting head is parallel to the X axis and the Y axis so as to easily control the insertion angle of the osteotome for the patients with smaller face or smaller oral cavity.
