Centrifugal drill bit for tooth planting technology

Abstract

The invention discloses a centrifugal drill bit for a tooth planting technology. The centrifugal drill bit comprises a drill body and a plurality of bit edges, a bit edge accommodating chamber is arranged in a position, close to the lower end, of the drill body, the bit edge accommodating chamber is provided with a plurality of gaps penetrating through the sidewall of the drill body, the quantityof the gaps is same to the quantity of the bit edges, the gaps are distributed in an equal included angle manner, the bit edges are slidably placed in the bit edge accommodating chamber, every bit edge comprises a cutter body, a clamping head and a cutter edge, the cutter body is trapezoid, the clamping head is connected with the upper base edge of the cutter body, the cutter edge is connected with the lower base edge of the cutter body, the cutter edge has an arc-shaped shape, the arc radius of the cutter edge is consistent to the radius of the drill body, the clamping heads of the bit edgesare provided with mutually attractive magnetic members, and the widths of the clamping heads are more than the width of the gaps. The centrifugal drill bit can drill bone debris in an alveolar bone while keeping wounds of the oral soft tissues and the compact bone part of the alveolar bone small, so an appropriate installation space is provided for a subsequent dental implant, and the rehabilitation period of patients is greatly shortened.

Description

technical field [0001] The invention relates to the field of dental implant technology. Background technique [0002] At present, in dental implant surgery, most of the dental implants are installed in the oral cavity by means of threaded connections. It is necessary to drill a large hole in the patient's alveolar bone first, and then fix the dental implant and the alveolar bone through threads. together. This operation will cause great damage to the alveolar bone and mucoperiosteal flap, which is prone to intraoperative bleeding and postoperative swelling, which prolongs the recovery time. The existing individualized planting technology knocks the implant into the extraction socket, although it does not need to drill holes in advance to cause damage, but it will also cause huge damage to the alveolar bone and even the entire jaw. In dental implant surgery, drill bits of standard specifications are used to drill holes of standard cylindrical shape when drilling holes for p...
