Dental implant surgery drill bit with auxiliary drill bit

Abstract

The invention discloses a dental implant surgery drill bit with an auxiliary drill bit. The dental implant surgery drill bit comprises a main drill body, an auxiliary drill and an auxiliary drill driving assembly, wherein the main drill body is a cylinder, the side wall of the main drill body is provided with at least one notch, the notch extends into the main drill body to form a flat auxiliary drill moving cavity, a rotating shaft installation through hole is also formed in the main drill body, two ends of the rotating shaft installation through hole are respectively communicated with the auxiliary drill moving cavity and the bottom surface of the main drill body, the auxiliary drill is disposed in the auxiliary drill moving cavity, the auxiliary drill driving assembly comprises a rotating shaft, an auxiliary drill gear and a main driving shaft, the auxiliary drill gear is disposed below the bottom surface of the main drill body, the rotating shaft penetrates through the rotating shaft installation through hole and is fixedly connected with the auxiliary drill and the auxiliary drill gear, and the main driving shaft is hinged to the bottom surface of the main drill body and engaged with the auxiliary drill gear. By adopting the dental implant surgery drill bit with the auxiliary drill bit, the bone mass of an alveolar bone of a patient can be reserved as far as possible in adrilling process, the injury of the patient is reduced, and the rehabilitation period of the patient is shortened.

Description

technical field [0001] The invention relates to the field of dental implant technology. Background technique [0002] At present, in the dental implant surgery, the dental implant is mostly installed in the oral cavity by means of threaded connection, which needs to drill a larger hole in the patient's alveolar bone. This operation will cause huge and unnecessary damage and bone loss to the alveolar bone and mucoperiosteal flap, thus prolonging the recovery period of the patient. In the implant surgery, the drill bit of the standard specification is used when drilling the patient, and the standard cylindrical hole is drilled, and the hole with a special structure cannot be drilled according to the special oral condition of the patient. Contents of the invention [0003] In view of the above disadvantages, the present invention provides a kind of drill that can use the auxiliary drill bit to perform step-shaped conical planting holes.
