Description

Implant axial guide device and positioning method of punching position

Technical Field

The invention relates to the technical field of dental medical treatment, in particular to an implant axial guide and a positioning method of a punching position.

Background

The common restoration methods for tooth loss include implant restoration, movable restoration, fixed restoration and the like, and implant restoration is one of the mainstream restoration methods, and an artificial tooth root needs to be implanted in a lost tooth part and then healed for a period of time to be arranged on a supporting abutment and an upper dental crown.

For patients with half-mouth or full-mouth dentition defects, a common repair method is All on four or All on six, that is, a denture with 4 or 6 implants for supporting a half mouth is implanted. Considering the factors of the mandibular nerve, the implantation risk is higher in the mandibular hemiforamina loss operation, because two mandibular nerves are distributed on the left and right sides of the mandible, the factors such as the implantation depth and angle of the implant need to be paid attention to, but the shorter implant does not affect the mandibular nerve, but the long-term stability and the mechanical property of the product are reduced, so that the implantation depth of the product is ensured by adjusting the implantation direction, the mandibular nerve can be prevented from being damaged, and the long-term stability of the product is ensured at the same time.

The guide devices commonly used in the market at present are surgical guide plates, surgical navigation and other modes. The operation guide plate is a customized product, has higher cost, is disposable and is easy to cause medical pollution; the surgical navigation is more advanced, but the cost is too high, and the surgical navigation is not suitable for mass consumption.

step 4, selecting a corresponding guide line group on the guider according to the cone beam CT of the lower jaw of the patient in the step 1, and taking a guide line junction point of the corresponding guide line group as a punching position of a channel of the base station;

and 5, selecting the corresponding guide wire in the guide wire group by the structure of the selected base station, and punching the channel of the base station along the corresponding guide wire.

The invention adopts the technical scheme to produce the beneficial effects that:

1. the guide line in the guider is determined according to the matching angle of the implant and the abutment, and the angle can effectively avoid the mandibular nerve and reduce the risk of damaging the mandibular nerve. The device can adapt to the guidance of a plurality of angle implantation directions, simultaneously, the metal material can be repeatedly used, the precise angle guidance is realized, the cost is low, the stability of the implantation direction of the product can be ensured, the problem of the implantation guidance during the repair of the existing mandibular half-mouth defective dentition is solved, and more solutions are provided for patients.

2. The guide device is made of TA3 material and can be bent according to different dental arches.

3. The method for positioning the punching position provided by the invention has the advantages of accurate positioning and reduction of manual errors.
