Description

Technical Field

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

[0002] Dental implant guides, also known as surgical guides or digital guides, are personalized tools used in dental implant surgery to precisely locate and guide the position, angle, and depth of implant placement. Based on the patient's preoperative oral CT scan data, they are created using computer-aided design software for three-dimensional reconstruction and virtual implant planning, and then manufactured using computer-aided manufacturing technologies such as 3D printing or CNC machining. The guides are usually made of biocompatible materials that can closely conform to the shape of the teeth or gums in the patient's mouth, and they come with metal guide tubes that are completely consistent with the design plan.

[0003] During the surgery, the doctor places a guide plate inside the patient's mouth and uses these guide tubes to make precise drilling, ensuring that the actual placement of the implant is completely consistent with the preoperative plan. Its core purpose is to accurately transfer the digital implant design to the actual surgical operation, significantly improving the accuracy, safety and predictability of the surgery, reducing surgical trauma, shortening the operation time, and reducing the risk of damage to adjacent important structures (such as the inferior alveolar nerve and maxillary sinus). It is a key component of digital implant technology.

[0004] However, in the current technology, after the dental implant guide plate is attached to the teeth in the patient's mouth, it is necessary to drill multiple times to drill the corresponding position of the implant. Most guide plates rely on passively fitting the oral anatomical structure and lack an active fixation mechanism. Under the mechanical load of drilling, the guide plate is prone to displacement, causing the drilling trajectory to deviate from the preoperative digital design, which directly affects the accuracy of implant placement.

[0005] In addition, conventional dental implant guides do not integrate tongue restraint during drilling. Unintentional tongue movement during surgery may intrude into the operating area, which not only interferes with the stability of the drill path but also increases the risk of accidental soft tissue injury, endangering the safety of the surgery. Therefore, we urgently need a new type of dental implant guide to solve the above problems. Utility Model Content

[0006] The dental implant guide plate provided by this utility model provides stable support to the base plate through three sets of support rods, and with the setting of three branch tubes on the three-way tube, it solves the problems mentioned in the background art that the drilling is prone to displacement, affecting the accuracy of implantation, and that the lack of tongue restraint function increases the surgical risk.

[0007] This utility model provides the following technical solution:

[0008] A dental implant guide plate includes a base plate that conforms to teeth in the oral cavity, the base plate having positioning holes for marking drilling positions, and further including: three sets of positioning posts integrally formed with the base plate for positioning, each positioning post having a hemispherical groove; a detachable tee tube disposed on the base plate, each of the three ends of the tee tube being threadedly connected to a support rod, the ends of the three sets of support rods being fixedly installed with protrusions adapted to the hemispherical grooves, the support rods supporting the base plate when the three sets of protrusions abut against the corresponding hemispherical grooves.

[0009] As a preferred technical solution of this utility model, the branch pipes on the three-way pipe are rectangular pipes with an auxiliary surface and an outwardly convex arc structure. When the support rod supports the substrate, the curved contour of the outwardly convex arc structure abuts against the tongue to restrict the tongue.

[0010] As a preferred technical solution of this utility model, the convex arc-shaped structure is a clamping block integrally formed with the rectangular tube, and the contact surface between the clamping block and the tongue is arc-shaped.

[0011] As a preferred technical solution of this utility model, the abutment block has a horizontal or vertical damping groove on its arc-shaped surface.

[0012] As a preferred technical solution of this utility model, the distance between the top of the clamping block and the rectangular tube is in the range of 1mm-6mm.

[0013] As a preferred embodiment of this utility model, the tee is a right-angle tee.

[0014] As a preferred embodiment of this utility model, the protrusion is a hemispherical structure.

[0015] Compared with the prior art, this utility model provides a dental implant guide plate, which has the following beneficial effects:

[0016] 1. In this dental implant guide plate, three sets of hemispherical grooves cooperate with the protrusions at the end of the support rod to form a triangular support area. The stability of the triangle is used to distribute the mechanical load during drilling and prevent the substrate from shifting. At the same time, the extension and retraction of the support rod can be adjusted by the threaded transmission to make the protrusions and hemispherical grooves fit tightly together, thereby adapting to different oral structures and ensuring that the substrate will not shift during drilling, which would affect the drilling accuracy.

[0017] 2. In this dental implant guide plate, the branch tubes on the three-way tube can effectively prevent the tongue from moving unintentionally during drilling, preventing the tongue from invading the operating area during the operation and interfering with the stability of the drill path, thus reducing the risk of accidental soft tissue injury. In addition, the clamping block is set on the branch tube, which can achieve the best tongue restraint effect.

[0018] This invention utilizes the triangular stabilizing area formed by the protrusions on the three sets of support rods and the hemispherical grooves on the substrate to distribute the load during drilling, achieve active fixation, and allow the substrate to adapt to different oral structures. This ensures that the drilling trajectory conforms to the preoperative digital design, effectively avoiding displacement problems. In conjunction with the clamping block, it can effectively prevent the tongue from moving unintentionally, avoid the tongue from interfering with the drill path, and reduce the risk of accidental injury.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Reference Figures 1-3 The dental implant guide plate in this embodiment includes a base plate 1 that fits into the teeth in the oral cavity. The base plate 1 is made of light-cured resin. The base plate 1 has positioning holes 2 for marking the drilling position. Here, the light-cured resin material allows the base plate 1 to accurately fit the shape of the teeth in the patient's oral cavity, providing a stable and well-fitting foundation support for the entire guide plate. The light-cured resin has good plasticity and molding precision, and can be customized according to the specific anatomical structure of the patient's oral cavity, ensuring the accuracy of the initial position of the guide plate during the operation and reducing the risk of displacement due to poor fit. At the same time, the cooperation of the base plate 1 with other structures provides a reliable platform for subsequent fixation and operation.

[0027] Furthermore, the positioning hole 2 is used to accurately mark the drilling position, ensuring that the drill bit operates according to the preoperative digital design trajectory, and is the core structure to ensure the accuracy of implant placement.

[0028] The dental implant guide plate in this embodiment also includes three sets of positioning posts 3 integrally formed with the base plate 1 for positioning, and the positioning posts 3 are provided with hemispherical grooves (not shown). Here, the depth of the hemispherical grooves ranges from 0.5mm to 1.5mm.

[0029] Furthermore, the depth of the hemispherical groove is preferably 1mm. At this depth, it ensures effective cooperation with the protrusion 7 while avoiding a decrease in the strength of the substrate 1 due to excessive depth. The three sets of hemispherical grooves are symmetrically distributed.

[0030] The dental implant guide plate in this embodiment also includes a detachable three-way tube 5 mounted on the base plate 1. The three-way tube 5 is a right-angle three-way tube, and each of its three ends is threadedly connected to a support rod 6. The ends of the three sets of support rods 6 are fixedly fitted with protrusions 7 that are adapted to the hemispherical grooves. When the three sets of protrusions 7 abut against the corresponding hemispherical grooves, the support rods 6 and the base plate 1 form a triangular support area. In this embodiment, the protrusions 7 are hemispherical in shape and have several anti-slip protrusions distributed on them. When the protrusions 7 on the support rods 6 abut against the inner wall of the hemispherical groove, the friction area is increased, preventing the protrusions 7 from sliding within the hemispherical groove. The right-angle three-way tube design allows for a compact layout of all components within the limited oral cavity space, facilitating the dentist's operation.

[0031] Here, the support rod 6 is easy to disassemble and adjust in length to adapt to the oral structure of different patients. The support rod 6 is made of medical-grade stainless steel, which has excellent mechanical properties and corrosion resistance. Furthermore, after the protrusions 7 on the three sets of support rods 6 abut against the corresponding three sets of hemispherical grooves, they form a stable triangular support area with the base plate 1, thereby achieving active fixation of the base plate 1 and effectively resisting the mechanical load during drilling to avoid displacement. Combined with the support rod 6 made of medical-grade stainless steel, the support strength of the base plate 1 can be ensured.

[0032] It should be noted that the branch pipe located inside the three-way pipe 5 (which can be understood as being located between the two straight branch pipes connected in a straight line on the substrate and the three-way pipe) is constructed as a rectangular pipe. The rectangular pipe is provided with an auxiliary surface, and the auxiliary surface has an outwardly convex arc structure. When the support rod 6 and the substrate 1 form a triangular support area, the curved contour of the outwardly convex arc structure abuts against the tongue to form a restriction area. This restriction area is used to restrict the movement space of the tongue. The material of the outwardly convex arc structure is food-grade PP. Here, the flexibility of the food-grade PP material can adapt to the pressure generated by the slight movement of the tongue, avoiding hard damage to the tongue, while having sufficient structural stability to ensure that the limiting effect is durable and reliable.

[0033] Here, the auxiliary surface is a convex surface with an outwardly convex arc structure.

[0034] In this embodiment, the outwardly convex arc-shaped structure is a clamping block 8, which is integrally formed with the rectangular tube. The contact surface between the clamping block 8 and the tongue is arc-shaped or wavy. A horizontally or vertically arranged damping groove 4 is provided on the arc-shaped surface of the clamping block 8. Here, the arc-shaped contact surface on the clamping block 8 is adapted to the natural contour of the tongue. When the triangular support area is formed, the clamping block 8 and the tongue form a restrictive area, preventing the tongue from swinging towards the surgical area. The horizontally or vertically arranged damping groove 4 on the arc-shaped surface of the clamping block 8 can increase the friction with the tongue mucosa, improve the limiting effect, and reduce the discomfort caused by local pressure.

[0035] In other embodiments, the convex arc structure can also be designed as a block array, with each unit being arc-shaped or wave-shaped. Damping grooves 4 are naturally formed between adjacent blocks, and the direction of the grooves depends on the block arrangement. This design not only enhances the friction with the tongue mucosa to improve the limiting effect, but also reduces the discomfort caused by local pressure by dispersing pressure.

[0036] Here, the damping groove 4 can be a straight groove or a curved groove.

[0037] It should be noted that the outward-convex arc structure is suitable for surgical scenarios where unilateral tongue movement is interfered with. For example, when performing implant surgery on the upper side of the mouth, the auxiliary surface with the outward-convex arc structure can be directed towards the tongue. The arc structure can prevent the tongue from swinging towards the surgical area and prevent the tongue from intruding into the operating space.

[0038] In this embodiment, the distance between the top of the abutment block 8 and the rectangular tube is 1mm-6mm. Since the substrate 1 is used for the upper or lower teeth in actual use, but the distance between the two and the tongue is different, the abutment block 8 on the three-way tube 5 has different heights to adapt to the height of the substrate 1 from the tongue when it is used in different positions. In actual surgery, the doctor can select the appropriate size of the abutment block 8 on the three-way tube 5 to adapt to the position of the patient's tongue.

[0039] Here, the different heights of the clamping blocks 8 can adapt to different tongue thicknesses of patients, ensuring the limiting effect while avoiding excessive pressure.

[0040] In this invention, the support rod 6 on the three-way tube 5 is rotated to move the support rod 6 axially, and the protrusion 7 on the support rod 6 is tightly abutted against the hemispherical groove on the base plate 1 to form a stable triangular support. After completing the above steps, the base plate 1 is fitted to the patient's teeth in the oral cavity to correct the distance of the support rod 6 protruding outward, thereby providing a good support effect. The tongue is then limited by the clamping block 8, and then the dental implant drilling operation is performed.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
