Guide plate for implantation of orthodontic micro-screw and manufacturing method thereof

Abstract

The invention discloses a guide plate for implantation of orthodontic micro-screw and a manufacturing method thereof. The method comprises: acquiring dental data from a CBCT image of a patient, rebuilding a three-dimensional image of jaw and teeth at an area to be subjected to implantation; acquiring a three-dimensional image of a to-be used micro-screw from a preset micro-screw three-dimensional image database, and regulating the three-dimensional image of the to-be used micro-screw at a preset position; establishing a first cylinder, enabling the direction of the cylinder to be same to the direction of the to-be used micro-screw and enabling the diameter of the cylinder to be larger than the diameter of a cuff part at the end of a screwdriver head; establishing a guiding part, namely forming a second cylinder at the periphery of the first cylinder along the axial direction, enabling the diameter of the second cylinder to be larger than the diameter of the first cylinder and enabling the two cylinders to be coaxial and same in height, and arranging a buffer distance between one end, facing to the phatnoma mucous membrane, of the cylinders and phatnoma mucous membrane; establishing a position-fixing part, namely painting the occlusion part and the occlusion surface at the appearance high point close to a tooth axial surface of the implantation part with an extended-crown preset-thickness coating; and establishing a connection part to connect the guiding part and the position-fixing part, so as to obtain a three-dimensional image of the guide plate, and printing.

Description

technical field [0001] The invention relates to the field of orthodontics, in particular to a guide plate for orthodontic microscrew implantation and a manufacturing method thereof. Background technique [0002] Temporary Anchorage Devices (TADs for short) are absolute anchorage devices placed in or on the bone surface for orthodontic treatment. Compared with traditional anchorage devices, TADs have the advantages of not requiring patient compliance. Compared with other bone implant anchorages, microscrew implants are smaller in size, have the advantages of easy operation, less damage, and lower price, and are currently the most commonly used type of anchorage implants. Using it can assist in the correction of difficult orthodontic cases and expand the indications for orthodontic treatment. However, in the implantation of microscrews, problems such as root damage and implant stability reduction caused by contact between the implant and the root have been found frequently. ...
