[ technical field ] A method for producing a semiconductor device

The invention relates to an auxiliary tool for oral implantation, and belongs to the field of medical equipment.

[ background of the invention ]

The common design of the implant is about 3mm at the minimum, and taking 3mm implant as an example, the minimum spacing of the crown part is less than 5mm, and the neck part is less than 6mm, which is not suitable for the implant treatment. When implanting surgery in the mouth, the mesial-distal direction: the implant implantation position needs to be placed at the midpoint position near and far from the deletion position; the near-far distance of the missing position needs to be known, so that the position can be known to place an implant with a proper diameter; buccal and lingual directions: the posterior dental implant needs to be placed in the middle of the dentition, and the shoulder of the anterior dental implant needs to be placed at the position of 1.5-2.0mm measured on the palate of the ideal appearance high point; after the window and other bones for healing the closed window are combined, the closed screw needs to be replaced by a healing base station.

At present, the method for measuring the implant position of an implant adopts caliper measurement or CBCT measurement, the near-far-middle distance of the implant position is firstly measured, and then divided by two to obtain the central distance of the implant position, and by adopting the two methods, the near-far-middle distance of the implant position can be preliminarily measured and the central distance of the implant position can be calculated.

[ summary of the invention ]

The invention aims to provide an auxiliary tool for oral implantation, so that an implant can be accurately positioned to the center of an implantation position.

In order to solve the technical problem, the preferred structure of the auxiliary tool for oral implantation comprises an inner ruler, an outer ruler, a gear and a shell, wherein racks are arranged on the inner ruler and the outer ruler, the racks of the inner ruler and the outer ruler are respectively meshed with the gear, the inner ruler and the outer ruler are in sliding connection with the shell, the gear and the shell are oppositely positioned along the sliding direction of the inner ruler or the outer ruler, a positioning ruler is arranged on the shell, the inner ruler is fixedly connected with an inner ruler limiting ruler, the outer ruler is fixedly connected with an outer ruler limiting ruler, the inner ruler limiting ruler and the outer ruler are positioned on two sides of the positioning ruler in an initial state, the distance between the inner ruler and the positioning ruler is the same, and central positioning marks are arranged on the positioning ruler, the inner ruler limiting ruler and the outer ruler limiting ruler, and the central positioning marks of the positioning ruler, the inner ruler and the outer ruler are positioned on the same horizontal line.
