[0002] The dental implant guide plate is a tool for assisting doctors to find the depth and direction of implants, and is extremely common in the surgery of implanting teeth in the oral cavity. The existing dental implant guide plate is usually a full-coated implant guide plate, which is usually arranged in an arc shape according to the normal arrangement of patient's teeth, and the front and rear guide plates of the implant guide plate are fixed on the front and rear sides of the patient's teeth, pressing the patient's teeth and gums.

[0003] Generally, the implant surgery takes 1 to several hours, and the patient's gums and roots are prone to pain after a long surgery, especially for patients with misaligned teeth. The normal implant guide plate is coated on the surface of the teeth, and since the implant guide plate is arranged according to the normal arrangement of teeth, the guide plate may form a concave due to misaligned teeth, and the binding force and pressure from the guide plate will be greater, resulting in more severe pain after the surgery.

[0004] In addition, the positioning components of the existing implant guide plate are fixed in number, and the retention force is relatively poor. When treating multiple teeth, the medical staff need to adjust the use position of the positioning components multiple times according to the tooth position, which may also cause problems in the positioning of the guide plate during the surgery. When adjusting the use position, the surgery time is increased, the surgery efficiency is lowered, and the patient is uncomfortable.

[0005] Therefore, how to design a dental implant guide plate with adjustable positioning to solve the above technical problems is a technical problem to be solved. SUMMARY

[0006] To solve the above problems, the purpose of the utility model is to provide a dental implant guide plate with adjustable positioning, which solves the problem of high coating degree of the existing full-coated implant guide plate on the patient's gums and teeth, causing great pressure on the teeth and gums of misaligned patients, low flexibility, and poor comfort.
