Description

Technical Field

[0001] This utility model relates to the field of dental implant technology, and in particular to a dental implant guide plate. Background Technology

[0002] With social development and improved living standards, dental health is receiving increasing attention. Human teeth can develop various problems due to both genetic predisposition and lifestyle habits. When dental issues become irreparable, patients often consider replacing them with artificial dentures. Dental implants, as the closest type of denture to natural teeth, are gaining popularity among patients.

[0003] In dental implant surgery, implant guides are usually needed to assist in the implantation process. Traditional implant guides typically have a round hole and a circular guide ring to ensure the directionality and depth of the implant. However, with the emergence of personalized custom implants and the need for alveolar bone preparation for other surgeries such as transplantation, there is an urgent clinical need for an auxiliary guide that can help doctors accurately complete the alveolar bone preparation operation of a specified shape. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dental implant guide to assist doctors in accurately completing alveolar bone preparation operations of a specified shape.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A dental implant guide includes a guide body and a guide ring. The guide body has a target tooth position operation area, and a sliding guide rail is provided on the target tooth position operation area. The guide ring slides with the sliding guide rail. The sliding guide rail includes an inlet section and a guide section, and the inlet section is used to guide the guide ring to the guide section.

[0007] Furthermore, an annular guide groove is formed on the outer surface of the guide ring, and the guide groove is formed in the middle of the guide ring so that the guide ring is I-shaped in the main viewing direction.

[0008] Furthermore, the shape of the guide plate body is preset according to the patient's intraoral scan data, and the material of the guide plate body is SG01 guide plate special resin.

[0009] Furthermore, the target tooth position operation area protrudes downwards from the guide plate body, and the protrusion shape is set to cylindrical.

[0010] Furthermore, the sliding guide rail is connected to the side of the guide plate body, and the guide ring is used to cooperate with the side-cutting drill bit.

[0011] Furthermore, the guide segment is arc-shaped, and one of the inlet segments is tangent to the guide segment.

[0012] The beneficial effects of this utility model are:

[0013] The guide plate body of this utility model is placed in a designated position in the patient's oral cavity. Through the setting of sliding guide rail and guide ring, and by the pre-designed shape of the guide section on the sliding guide rail, the guide ring slides along the guide section, thereby guiding the movement trajectory of the lateral cutting drill bit. It plays a guiding role when cutting the alveolar bone and cortical bone of the upper and lower teeth. It is suitable for situations such as dental implants and autologous tooth transplantation that require specific alveolar bone preparation. It has the characteristics of easy disassembly and assembly and good cutting effect, which facilitates the doctor's surgical operation and improves the patient's experience.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] The dental implant guide invented by our company was initially designed to assist in the production of our personalized additive manufacturing root implant systems. During implant surgery, especially in multi-rooted posterior teeth, it is often necessary to prepare the alveolar bone for surgical purposes, considering medical, engineering, and aesthetic factors. Traditional preparation methods rely primarily on direct manipulation by the dentist, which cannot achieve precise quantitative manipulation. Experiments have shown that this guide, in addition to assisting in the implantation of our products, also has significant clinical application value in other surgeries requiring alveolar bone preparation, such as transplant surgeries.

[0024] like Figure 1-4 As shown in this embodiment, a dental implant guide includes a guide body 11 and a guide ring 8. The shape of the guide body 1 is preset according to the patient's intraoral scan data, and the material of the guide body 1 is SG01 guide-specific resin. The overall shape of the guide body 1 is no different from that of a traditional implant guide. It is manufactured using additive manufacturing technology based on the patient's intraoral scan data. Unlike implant guides, its target tooth position circular operating area 5 contains a personalized sliding guide rail 6.

[0025] Please see Figure 1 and Figure 2The guide plate body 1 has a target tooth position operation area formed on it. This target tooth position operation area protrudes downwards from the guide plate body 1 and is cylindrical in shape. The protrusion of the target tooth position operation area can be inserted into the patient's alveolar socket, and its size depends on the patient's oral condition. A sliding guide rail 6 is provided on the target tooth position operation area. The guide ring 8 slides in cooperation with the sliding guide rail 6. The sliding guide rail 6 includes an inlet section 4 and a guide section. The inlet section 4 guides the guide ring 8 to the guide section. The sliding guide rail 6 communicates with the side of the guide plate body 1, and the guide ring 8 is used to cooperate with a side-cutting drill bit. The guide section is arc-shaped, with one of the inlet sections 4 and the guide section being tangent.

[0026] Please see Figure 3 The hollowed-out portion of the sliding guide rail 6 has an I-shaped structure. The central boss portion provides limited clamping to the I-shaped cylindrical guide ring 8, allowing the guide ring 8 to slide smoothly and without resistance within the guide rail. In this embodiment, the inlet section 4 includes two ends, respectively positioned at the beginning and end of the guide section. The two inlet sections 4 are arranged parallel to each other. The distance between the upper and lower parts of the two inlet sections 4 on the sliding guide rail 6 is 4.6 mm, the distance between the middle parts is 4.3 mm, the height of the upper part is 1.62 mm, the height of the middle part is 1.67 mm, and the height of the lower part depends on the patient's oral cavity condition.

[0027] Please see Figure 4 The outer surface of the guide ring 8 has an annular guide groove 7 formed therein, and the guide groove 7 is formed in the middle of the guide ring 8, making the guide ring 8 H-shaped in the main viewing direction. In this embodiment, the shape of the guide ring 8 in both the side view and the cross-sectional view is set to H-shape. The guide groove 7 divides the guide ring 8 into upper and lower parts, wherein the diameter of the upper and lower parts of the guide ring 8 is set to 4.48 mm, and the diameter of the middle part is set to 4 mm. The height of the upper and lower parts is set to 1.50 mm, and the height of the middle part is 1.55 mm.

[0028] By combining a customized guide rail, guide ring 8, and a dental drill with lateral cutting capability, the hole preparation operation that previously required doctors to rely on experience can be completed by specifying the shape, depth, and amount of bone removed.

[0029] Working principle:

[0030] When using a dental implant guide, the guide body 1 is first placed in the designated position in the patient's mouth. The outer surface 2 and inner surface 3 of the guide are additively manufactured based on the patient's intraoral scan data, allowing for a better and closer fit to the patient's mouth. The circular operating area 55 of the target tooth position is always directly aligned with the patient's target tooth position. The guide ring 8 is then fitted onto the drill bit required for the surgery through the hole in the guide ring 8. Subsequently, the guide groove 7 of the guide ring 8 is inserted into the sliding guide rail 6, allowing the drill bit and guide ring 8 to slide along the guide rail 6 with low resistance and without jamming. This provides guidance when cutting the alveolar bone and cortical bone of the upper and lower jaws, enabling more precise and efficient hole preparation. It is easy to assemble and disassemble and has a good cutting effect, making it suitable for dental implants and autologous tooth transplantation. This facilitates the surgeon's operation and improves the patient's experience.

[0031] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope.
