Description

Technical Field

[0001] The utility model relates to the technical field of oral implant guides, and particularly relates to a combined magnetic guide for full-mouth implantation. Background Art

[0002] Oral implantation refers to surgically implanting artificial implants into the jawbone at the tooth-deficient site, and connecting abutments and crowns to the jawbone to restore functions such as chewing and appearance of patients. An implant guide, also known as an implant surgical guide, is short for an implant guiding template, which is a personalized surgical auxiliary instrument that accurately transfers the pre-determined plan before implantation to the patient.

[0003] Before the oral implant surgery, an implant guide corresponding to the patient's internal teeth in the oral cavity needs to be made. The implant guide can help doctors determine the implantation position of the implant during the surgery. Therefore, the implant guide is a very important auxiliary tool in oral implant surgery, which can accurately guide the implant positioning and cavity preparation, avoid complications caused by accidents, reduce the surgical difficulty, and greatly improve the accuracy and efficiency of oral implantation.

[0004] The existing implant guides are mainly divided into at least two independent digital guides such as positioning guides, implant guides, and osteotomy guides required according to the specific surgical conditions.

[0005] During the implant surgery process, it is necessary to replace other types of guides according to the positions of the retention pins. When replacing different guides, it is necessary to use retention pins to position different guides, which causes the retention pins to be inserted and removed multiple times, resulting in position deviation of the guide, making it impossible for the subsequent guide to be firmly seated. Eventually, the position and angle of the implant will also deviate, affecting the implant accuracy.

[0006] In addition, the conventional guide is directly generated by simulating tooth extraction, but certain deviations will also occur during the digital software operation and simulation process. During the implant process, situations such as mucosal swelling may occur. The actual situation is different from the simulated situation. Using the traditional mucosal guide will cause the position of the guide retention pin to deviate, making the guide unstable to wear and difficult to accurately position, affecting the final implant accuracy.

[0007] Chinese Patent Application No. 201520544192.2 discloses a positioning guide used in conjunction with an implant, including: a positioning plate, a catheter, and a positioning tube. The shape of the positioning plate matches the shape of the alveolar ridge; a catheter through-hole is provided on the positioning plate, and the position of the catheter through-hole corresponds to the position of the implant on the alveolar ridge. The catheter is provided at the catheter through-hole and communicates with the catheter through-hole; a positioning tube through-hole is provided at the outer edge of the positioning plate, and the positioning tube is provided at the positioning tube through-hole and communicates with the positioning tube through-hole.

[0008] When using the above-mentioned positioning guide plate to prepare holes in the jawbone, it is necessary to replace the hole-preparing guide plate. Therefore, when installing this positioning plate, repeated positioning is required, which is likely to cause positioning errors and affect the implant accuracy. Summary of the Invention

[0009] The present invention aims to overcome the defects in the above-mentioned prior art and provides a combined magnetic adsorption guide plate for full-mouth implantation with accurate positioning, safety and reliability.

[0013] As a preferred solution of the present invention, the retention guide plate is arranged in a covering manner on the tooth row groove, and a covering cavity corresponding to the tooth row is formed in the middle of the fixed guide plate.

[0014] As a preferred solution of the present invention, a plurality of adsorption magnets are installed on the base guide plate, a plurality of retention magnets magnetically attracted to the adsorption magnets are formed on the retention guide plate, and a plurality of connection magnets magnetically attracted to the adsorption magnets are formed on the hole-preparing guide plate.

[0015] As a preferred solution of the present invention, adsorption magnets are installed on both the tongue-side fitting surface and the lip-side arc-shaped member.

[0016] As a preferred solution of the present invention, truncated cone-shaped grooves with gradually decreasing sizes from top to bottom are formed in the middle of the tongue-side connection seat and the lip-side connection seat, and the tongue-side retention member, the lip-side retention member, the tongue-side insertion member and the lip-side insertion member are truncated cone-shaped pins corresponding to the truncated cone-shaped grooves.

[0017] As a preferred embodiment of the present utility model, a connecting rod for connecting each lingual plug-in member, labial plug-in member, connecting magnet and positioning guide ring is formed inside the hole preparation guide plate.

During the whole operation process, the base guide plate and the retention pins do not need to be taken out, reducing the deviation of the guide plate position caused by repeated insertion and replacement of the retention pins;
