Description

Technical Field

[0001] The utility model relates to the technical field of oral implantation, in particular to an integrated metal implantation guide plate. Background Art

[0002] Dental implant restoration is a method of implanting an implant into the jawbone, fitting it tightly with the jawbone to form a stable support point, and installing a denture on this support point to repair missing teeth. Dental implants can restore the chewing function of teeth well without destroying one's own teeth. Compared with fixed restorations, implant restorations do not damage adjacent teeth and preserve the patient's healthy natural teeth; compared with removable restorations, implant restorations are more secure and patients do not have the foreign body sensation brought by removable restorations. In recent years, implant restorations have gradually become the preferred restoration method.

[0003] During implant surgery, since CT scans can only observe the situation inside the mouth but cannot directly determine the specific location of the implant, in order to understand the specific situation of the implant site, it is necessary to perform a flap operation on the gums of the toothless part during the operation; and the implant placement basically depends on the surgeon's experience and feeling. If the surgeon is inexperienced and cannot effectively grasp the angle and depth of the implant, or when the patient's oral situation is complicated, such as the mandibular nerve canal and tooth root are close together, the maxillary sinus is too low, etc., it is easy for medical accidents such as implant penetration and nerve canal damage to occur, and the implant guide can greatly reduce the occurrence of these disadvantages.

[0004] The implant guide is an auxiliary implant surgery tool that is made through 3D printing technology by simulating implant surgery planning through computer software, avoiding important neural tubes, maxillary sinuses, etc., determining the location, height, depth, angle, etc. of the implant. The surgical guide uses a circular cutting drill to perform circular cutting surgery on the edentulous gum area, which can avoid gingival flap surgery and reduce surgical trauma. Secondly, the surgical guide can be used for multiple tooth implants, effectively reducing the operation time.

[0005] The existing implant guides are made of resin materials and metal guide rings. In recent years, the defects of resin implant guides have been exposed: due to the different materials of the guide and the guide ring, it takes a lot of time to adjust the grinding every time the two are matched after processing; and if the grinding size is not controlled, the guide ring and the guide plate will be loose, which will cause the guide to fall off during the operation. Due to the shaking of the guide ring, the implantation position, angle and depth of the implant guided by the guide ring will shift, which will lose the original function of the guide ring.

[0006] In addition to the above-mentioned shortcomings, there are still many problems with resin implant guides in clinical surgery in recent years: 1. The raw material of the resin guide is a high molecular polymer with an unpleasant odor, which is unbearable when the guide is worn in the patient's mouth; 2. The resin guide has a small bending strength. If it is left for too long or exposed to high temperature for a long time, it is easy to deform, causing the implantation position of the implant to change during surgery; 3. The strength of the resin guide is not high. During surgery, the pressure of the pressing plate or the impact force brought by the drill can easily cause the guide to break. This is also the most serious defect of the existing resin implant guide in surgery; 4. The structure of the existing resin implant guide is complex, and a large number of support plates need to be designed to stabilize the strength of the guide, which makes the guide a little bulky. The patient feels like there is a foreign body in the mouth, the doctor's field of vision is limited during surgery, and it may even block the use of surgical tools.

[0007] The patent application with publication number CN219645915U discloses an integrated metal implant guide. The digital titanium alloy implant surgical guide made by the application is thinner and lighter than the traditional resin guide, which can effectively overcome many problems of the above-mentioned resin implant guide. However, the application still has certain problems. The metal guide body of the application is too thick, the positioning pin guide ring is too thick, and the positioning groove and observation window are not large enough, which ultimately leads to high material costs for the metal guide, and it is also inconvenient for doctors to operate, and the thinness of the metal is not well reflected.

[0008] In summary, the implant guides in the prior art still have technical problems such as unreasonable design, poor reliability, insufficient strength, and inconvenient operation. Utility Model Content

[0009] The purpose of the utility model is to provide an integrated metal implant guide plate to solve the problems of existing resin guide plates such as insufficient strength, the need for support plates for stability, unpleasant odor, and easy deformation due to the external environment.

[0010] The technical solution of the utility model is as follows:

[0011] An integrated metal implant guide plate, comprising a guide plate body, wherein the guide plate body is provided with at least three independent positioning buckles, wherein any number of the positioning buckles can be replaced by positioning nail guide rings, wherein the positioning buckles or positioning nail guide rings are distributed at intervals, and adjacent positioning buckles or positioning nail guide rings are separated by at least one tooth position;

[0027] Example 1

[0028] The utility model provides an integrated metal planting guide plate, combined with Figure 1 The front structure diagram of the integrated metal planting guide plate of the utility model Figure 2 The schematic diagram of the back structure of the integrated metal planting guide of the utility model includes a guide body 6, on which a planting guide ring 1 is provided. Both the guide body 6 and the planting guide ring 1 are made of metal, and the guide body 6 and the planting guide ring 1 are connected as a whole.

[0029] The guide plate body 6 is provided with at least three independent, spaced-apart positioning buckles 3, and the positioning buckles 3 can be replaced by any number of positioning pin guide rings 5. The positioning buckles 3 or positioning pin guide rings 5 ​​are spaced-apart, and adjacent positioning buckles 3 or positioning pin guide rings 5 ​​are spaced apart from each other by at least one tooth position; an implantation guide ring 1 is provided between the spaced-apart positioning buckles 3 or positioning pin guide rings 5, and the implantation guide ring 1 is integrally connected to the guide plate body 6, and the inner side 7 of the guide plate body is attached to the corresponding tooth surface.

[0030] The utility model is also preferably designed based on intraoral scanning or plaster models, so as to ensure the matching degree of the positioning buckle 3 and the guide plate body 6 with the corresponding abutment teeth, and at the same time ensure the accurate position of the implant guide ring 1. The manufacturing method preferably adopts a laser selective melting process to process and shape dental metal powder, and the material is preferably titanium alloy. The integrated metal implant guide of the utility model does not need to design the guide plate body 6 for all abutment teeth when designing, but selects some abutment teeth to set the corresponding positioning buckle 3. After reducing the number of positioning abutment teeth, the possibility of positioning incompatibility can be reduced. At the same time, adjacent positioning buckles 3 or positioning pin guide rings 5 ​​are separated by at least one tooth position and connected by the guide plate body 6. Even if the relative positions of adjacent positioning buckles 3 or positioning pin guide rings 5 ​​have some errors, the positioning buckles 3 can be worn on the abutment teeth through the elasticity of the guide plate body 6. In addition, due to the reduction in the volume of the guide plate body 6, the metal guide plate of the present application can be lighter than the existing metal guide plate, reducing the patient's load-bearing burden and foreign body sensation. The metal guide plate has a simpler structure, which gives the doctor a clearer surgical field of view, more effective heat dissipation, and greatly improves the surgical effect.

[0031] The positioning buckle 3 is used to lock the abutment. The positioning buckle 3 can be designed for a single abutment, or not for abutment in special cases. The abutment design will reduce the burden on patients, so the abutment design is a common design. The positioning buckle 3 is open and presents a clamping ring shape. The outer side of the positioning buckle 3 is a smooth structure, which can further reduce the difficulty of wearing, reduce the volume of the conductor body, and is not prone to incompatibility problems. At this time, the implant guide ring 1 is connected to the outside of the adjacent positioning buckle 3 to guide the path of the implant drill. Its appearance is a cylindrical structure, which is convenient for use with implant tools. At least one of the at least three independent positioning buckles 3 is arranged at the end of the guide plate body 6, and any three positioning buckles 3 present a triangular positioning feature. At least one positioning buckle 3 is connected to the implant guide ring 1 on both sides, and the positioning buckle 3 is connected to the guide plate body 6 through a connecting plate 2, and the connecting plate 2 is arranged on the inner side of the guide plate body 6.

[0032] Traditional resin materials have a certain degree of transparency, so it is possible to directly observe whether the guide plate is worn in place, but this is not the case with metal guide plates. For this reason, in a preferred embodiment of the present application, the positioning buckle is designed in the form of a clasp, which can better cooperate with the abutment tooth and has a larger observation window.

[0033] The implant guide ring 1 is directly connected to the guide plate body 6, which is convenient for the matching of the implant tool and the implant guide ring 1. The outer side is connected with a positioning nail guide ring 5 to stabilize the position of the guide plate body 6 during the operation and prevent sliding during the operation.

[0034] In special cases where the patient does not have too many teeth to support the abutment design, a positioning pin guide ring 5 design will be adopted. The positioning pin guide ring 5 of the integrated metal implant guide of the utility model is located on the labial buccal side or the lingual side. The positioning pin guide ring 5 is directly connected to the guide body 6. The positioning pin guide ring 5 is located on the outside of the guide body 6. The positioning pin guide ring 5 is in the shape of a cylinder with a positioning hole in the middle through which the positioning pin can pass. The two positioning pin guide rings 5 ​​present a triangular positioning feature with any positioning buckle 3. The inner wall of the positioning buckle 3 is provided with a positioning plate 4 to which the abutment can be attached. The positioning buckle 3 can also be designed with the positioning plate 4 according to the surface morphology of the abutment, which can better fix the guide body 6. The wrapping range of the positioning plate 4 does not exceed one-fourth of the abutment, reducing the area of ​​the positioning buckle 3 and facilitating better observation of the surgical operation.

[0035] The positioning pin guide ring 5 is located on the buccal or lingual side, and is tilted and directly connected to the implant guide ring 1 through the guide body 6. Providing two positioning pin guide rings 5 ​​can make up for the problem of insufficient vertical stability of the implant guide, and ensure the smooth progress of the implantation operation.

[0036] The position of the positioning nail guide ring 5 can be set according to specific needs, for example, it can be set to form a triangle with the positioning buckle 3. In this way, the positioning nail guide ring 5 can meet the stability in both the horizontal and vertical directions, ensuring that accidents are not likely to occur during the operation. The diameter range of the fixed nail guide ring 5 is about 1.5 mm, and a smaller and larger fixed nail guide ring can reduce the weight of the guide body, achieving better stability and wearing comfort.

[0037] In order to make the positioning buckle 3 have a larger window and reduce consumables as much as possible, the guide plate body 6 usually wraps around no more than half of the tooth surface, which can reduce the patient's load-bearing burden and foreign body sensation.

[0038] In the preferred embodiment of the present application, the thickness of the positioning buckle 3 is 0.5-1.0 mm, the shape of the positioning buckle 3 and the positioning plate 4 are adapted to the abutment, and the inner side 7 of the guide plate body is adapted to the outer shape of the abutment. Therefore, the outer side of the existing metal positioning buckle is usually determined by increasing the thickness of the inner surface contour to form a shape similar to the surface of the tooth. However, in the preferred embodiment of the present application, the outer side of the guide plate body 6 preferably adopts a smooth structure, which can not only improve the comfort of wearing, but also make 3D printing and later polishing easier. The implantation guide ring 1 and the guide plate body 6 are an integrated structure, which is convenient for printing and processing together. The implantation guide ring 1 is a cylindrical structure as a whole, the roughness of the inner wall of the guide ring Ra≤1.6μm, and the clearance fit tolerance between the inner wall of the guide ring and the tool is +0.01mm~+0.08mm, the upper part is flat and fits the tool, and the lower plane of the implantation guide ring 1 is the inner side 7 of the guide plate body.

[0039] The utility model discloses an integrated metal implant guide which only selects some abutment teeth to set corresponding independent positioning buckles, thereby reducing the possibility of incompatibility of characteristic parts during wearing, thereby reducing the difficulty of wearing the guide plate, and also eliminates the positioning groove and observation window and replaces them with a smaller clamp-ring-shaped positioning buckle, so that the surgical process can be directly observed through the positioning buckle, and the doctor's operation convenience is improved; the integrated design combined with the positioning buckle reduces the overall volume of the guide plate, making the patient's experience more comfortable.

[0040] The utility model discloses an integrated metal implant guide plate to solve the problems of existing resin guide plates such as loosening / displacement between the guide ring and the guide plate / insufficient strength to fall off during surgery, as well as the defects of requiring a support plate for stability, unpleasant odor, and easy deformation due to the external environment.
