Abstract

A dental implantation apparatus capable of implementing vibration reduction by electromagnetic suspension. The dental implantation apparatus comprises a housing (1), a housing cover (2), a central body (3), a vibrating shaft (4), a driving element, and a central body cover (6). The dental implantation apparatus is safe and efficient, and a dental implant implanted by said apparatus has better initial stability.
