Description

Technical Field

[0001] The invention relates to the field of dental medical instruments, in particular to a bone side wall translation positioning tool for dental implants. Background Art

[0002] Dental implants are a mature technology that requires drilling a cavity for the implant in the alveolar bone before the implant can be screwed in. Existing dental implant surgical methods can be divided into the following three types: the first is the 3D guide implant method, the second is the real-time navigation tracking method, and the third is the freehand implant method. The 3D guide implant method and the real-time navigation tracking method are expensive, require matching tools, and require 3D printed guides and 3D printed alignment blocks in advance. Immediate implantation on the spot is not possible. Usually, doctors will choose the freehand implant method. Based on X-rays and patient examination reports, doctors directly perform freehand implantation in clinical practice. This method has no reference and is very easy to produce deviations.

[0003] Patent CN 209074957 introduces a rapid positioning ruler for the mesiodistal implantation position of an implant, but the invention can only assist in mesiodistal positioning and cannot assist in buccal and lingual lateral positioning.

[0004] Patent CN 204351952 introduces an oral implant parallel positioner. Although this invention can assist in the parallelism of multiple dental implants, it cannot assist in buccal and lingual positioning. Summary of the invention

[0005] The present invention patent introduces a new type of bone side wall translation positioning tool for dental implants. Compared with the positioning tool mentioned in the above invention patent, it realizes precise positioning during implant drilling. By finding reference objects during the implantation process, the prepared holes for implantation are close to the treatment plan, which effectively solves the defects of inaccurate positioning, ineffective positioning and deviation during implantation in existing positioning tools and methods.

[0006] The components of a bone side wall translation positioning tool for dental implants include: a scale, a fixed side scale body, a movable side scale body, a fixed side measuring head and a movable side measuring head. The fixed side scale body and the movable side scale body are rotatably connected through a pin shaft, wherein the fixed side scale body is fixed to the scale, the end of the movable side scale body is in a pointer style, the front end of the fixed side scale body is connected to the fixed side measuring head, and the front end of the movable side scale body is connected to the movable side measuring head. A spring is provided between the fixed side scale body and the movable side scale body to enable the movable side scale body to automatically reset.

[0007] Preferably, the bone side wall translation positioning tool for dental implants is a measuring tool for dental implants, which is specifically used to measure the thickness of the bone side wall at the implantation position of the dental implant, so as to facilitate the selection of a drill bit of a certain specification for drilling holes during implantation.

[0008] Preferably, the ruler is provided with 15 scales and pointer tips on both sides, the total range is 0∽15mm, the movable side ruler body is in contact with the fixed side ruler body when it is in the initial position, and the pointer at the end of the movable side ruler body is located at the zero scale of the ruler.

[0009] Preferably, when the side wall measuring ruler is used to measure the anterior teeth area, both the fixed side measuring head and the movable side measuring head are straight tube measuring heads.

[0010] Preferably, when the side wall measuring ruler is used to measure the posterior teeth area, since some patients have a recessed posterior alveolar ridge, only the fixed side measuring head is a straight tube measuring head, while the movable side measuring head is a curved tube measuring head, so that the movable side measuring head can conveniently probe into the recessed area of ​​the posterior alveolar ridge for measurement.

[0011] Preferably, the front ends of the straight tube measuring head and the curved tube measuring head are round heads or mushroom heads, which can reduce the tension and pain of patients when seeking medical treatment and improve the patients' medical experience.

[0012] Preferably, three scale lines are provided at the front end of the straight tube measuring head, which are respectively 8mm, 10mm and 12mm or 4mm, 6mm and 8mm away from the front end of the straight tube measuring head. There is an angle between the measuring head and the side ruler body, and the angle is 10∽350 degrees in diameter. When the angle is 180 degrees, it is a right-angle measuring head, and the other angles are all curved tube measuring heads. The diameter of the head of the measuring head is 2∽5mm, and the diameter of the tail is 2.5∽5mm.

[0013] The positive progressive effect of the present invention is that the present invention utilizes a novel bone side wall translation positioning tool for dental implants in combination with its translation positioning method, which can not only accurately measure the distance between the inner wall of the prepared hole and the outer side of the alveolar ridge, but also, through the bone side wall translation positioning method, can correct and move the drilling direction of the drill bit during the implant drilling process, so that the actual prepared hole position can be as close as possible to the prepared hole plan designed under the X-ray film, thereby achieving accurate positioning of the implant cavity, reducing possible deviations in the actual implant process, and effectively saving the doctor's treatment time and cost.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0028] In the description of the patent of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the patent of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the patent of the present invention.

[0029] like Figures 1 to 6As shown, the present invention is a novel bone side wall translation positioning tool for dental implants, comprising: a scale 1, a fixed side scale body 2, a movable side scale body 3, a fixed side measuring head 4, and a movable side measuring head 5. The fixed side scale body 2 and the movable side scale body 3 are rotatably connected by a pin shaft, wherein the fixed side scale body 2 is fixed to the scale 1, the end of the movable side scale body 3 is in the form of a pointer, the front end of the fixed side scale body 2 is connected to the fixed side measuring head 4, the front end of the movable side scale body 3 is connected to the movable side measuring head 5, and a spring is provided between the fixed side scale body 2 and the movable side scale body 3 to automatically reset the movable side scale body.

[0030] The ruler 1 has 15 scales on both sides, each scale has a size of 1 mm, and the total range is 0-15 mm.

[0031] Pointer tips are arranged on both the front and back sides of the end of the movable side ruler body 3.

[0032] When the movable side ruler body 3 is located at the initial position, it fits with the fixed side ruler body 2, and the pointer at the end of the movable side ruler body 3 is located at the zero scale of the scale 1.

[0033] When the side wall measuring ruler is used to measure the anterior teeth area, both the fixed side measuring head 4 and the movable side measuring head 5 are straight tube measuring heads. Figure 7 As shown, the fixed-side measuring head 4 is inserted into the prepared hole, and the movable-side measuring head 5 is placed on the side wall of the lingual alveolar ridge for measurement.

[0034] When measuring the posterior teeth, the side wall measuring ruler Figure 8 As shown, since some patients have a recessed posterior alveolar ridge, only the fixed-side measuring head 4 is a straight-tube measuring head, while the movable-side measuring head 5 is a curved-tube measuring head, so that the movable-side measuring head 5 can conveniently probe into the recessed area of ​​the posterior alveolar ridge for measurement.

[0035] The front end of the straight pipe measuring head and the curved pipe measuring head is a round head or a mushroom head, such as Fig.11 and Fig.12 Such a front end of the measuring head can reduce the tension and pain of patients when seeking medical treatment and improve the patient's medical experience.

[0036] There are three scale lines at the front end of the straight tube measuring head, which are 8mm, 10mm and 12mm away from the front end of the straight tube measuring head respectively. When measuring, the depth of the measuring head inserted into the prepared hole can be intuitively obtained.

[0037] The working principle of the patent of this invention is as follows:

[0038] like Figure 7 and Figure 8As shown, the patented new bone side wall translation positioning tool for dental implants is suitable for measuring the distance between the inner wall of the prepared hole and the outer side of the alveolar ridge during surgery. By measuring the hole opening, the middle of the hole, and the bottom of the hole, it can be known whether the angle and position of the measured prepared hole meet the expected target, and the prepared hole angle can be adjusted in time. Its advantage is that while reducing the treatment time cost, the actual prepared hole position can be as close as possible to the prepared hole plan designed under the X-ray film, reducing the deviation generated during the actual implantation process.

[0039] like Fig. 9 and Fig.10 As shown in the figure, the angle of the measuring head in the new bone side wall translation positioning tool for dental implants is not limited to a specific angle, and the installation method and position of the measuring head and the ruler are also flexible. This new processing technology is shown in the figure, B is the horizontal part of the ruler, and A is the joint. A hole is drilled in the vertical direction at the horizontal head B of the ruler, and the joint A is inserted, and then laser welding is performed to obtain a new bone side wall translation positioning tool such as Fig. 9 As shown in FIG. 1 , a hole is drilled horizontally at the head B of the ulnar body, and the connector A is inserted and then laser welded to obtain another new type of bone side wall translation positioning tool. Fig.10 shown.

[0040] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0041] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
