Description

Cortical bone forming drill

Technical Field

The utility model relates to the technical field of medical instruments in stomatology, in particular to a cortical bone forming drill.

Background

Due to the high treatment success rate, dental implant restoration has become the first-choice restoration solution for patients with missing teeth. Wherein immediate implantation refers to immediate implantation of a dental implant during tooth extraction, and the treatment method can reduce the operation frequency and the operation trauma, so the method is widely favored by patients and doctors. Modern immediate implantation requires bone grafting of the palatal side implant to leave a jumping gap, which results in a lack of cortical bone support on the buccal side (for tooth extraction) when the implant is implanted in a fresh extraction socket, while the implant may be subjected to buccal thrust on the implant by the palatal side cortical bone, resulting in poor repair when positioned in the designed position.

In view of the above disadvantages of the prior art, the present invention provides a cortical bone shaping drill, which reduces the thrust of the palatal cortical bone, helps to relieve part of the palatal cortical bone, and reduces the buccal thrust generated to the implant, so as to obtain a better three-dimensional position for implant implantation.

In order to achieve the above and other related objects, the present invention provides a cortical bone shaping drill, which comprises a connecting portion of a head of an implant, a connecting rod, and a working end, wherein the working end comprises a cutting section, a transition section, and a guiding head in sequence from a proximal connecting rod end to a distal connecting rod end, and a cutting edge is arranged on the cutting section.

Preferably, the planter head connecting part is connected with the planter head.

More preferably, the planter head connecting part is a clamping groove.

Preferably, the guide head is a cylindrical guide head.

More preferably, the diameter of the guide head is 1.5-2.5 mm, and the length is 1.5-3.5 mm.

Preferably, the diameter of the transition section is 1-2 mm, and the length of the transition section is 0.5-1.5 mm.

Preferably, the length of the cutting section is 6-8 mm.

Preferably, the cutting section is conical.

More preferably, the cutting section is provided with a plurality of blades arranged in a surrounding manner, and the blades are provided with cutting edges.

More preferably, the diameter of the end of the near connecting rod is 1-2.5 mm, and the diameter of the end of the far connecting rod is 1.5-2.5 mm.

The technical scheme has the following beneficial effects: the cortical bone forming drill reduces the thrust of the palatal cortical bone, helps to relieve part of the palatal cortical bone, and reduces the buccal thrust generated on the implant, so as to obtain a better three-dimensional position for implanting the implant.
