Abstract
A piezotome operation unit for lifting a maxillary sinus at a position of placement of an implant upon lifting the maxillary sinus, which forms and enlarges the vertical hole with ease in a remaining bone of the maxillary sinus though vertical approaching, and upon forming a lateral window below a malar bone through lateral approaching, prevents a maxillary membrane from becoming damaged, thereby ensuring continuous, safe lifting so that the operating time is shortened and the efficiency of the operation is maximized.
