Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of oral implant positioning, and in particular to an oral implant positioning device. Background Art
[0002] In the field of oral implants, biocompatible materials (pure titanium implants) are used to simulate natural tooth roots and achieve direct mechanical bonding with the jawbone, thereby restoring the patient's dental function. In order to ensure the optimal position, angle, and depth of implant placement, positioning technology is required to scan the three-dimensional effects of the jawbone, neural tube, and blood vessels to avoid affecting the aesthetics and complications during implantation.
[0003] After searching, a Chinese patent disclosed a three-dimensional detection and positioning device for dental implants (CN216652539U), which includes a detection sensor, and software and hardware control devices. The detection sensor consists of a spiral coil at the front end and an electrode at the tail end. When it senses a metal implant buried in the gums, the inductance of the coil changes, and the frequency of the oscillation circuit changes accordingly to achieve the detection and positioning effect. It can detect in three dimensions, including the top of the implant, the outside of the implant buried in the gums, and the inside of the gums, and can quickly locate whether there is an implant inside the gums and the exact position of the implant. It can not only facilitate the implant doctor to accurately locate the implant in the patient's mouth, but also reduce the economic burden on the patient and reduce harm to the human body.
[0004] However, in actual use, it was found that the above-mentioned patents and existing positioning devices mostly use a handheld control device to extend the sensor into the oral cavity, which requires the patient to keep his mouth open. During long-term positioning, the patient's mouth is prone to shaking, resulting in positioning drift. In addition, the doctor needs to hold the control device in one hand and perform the implant operation with the other hand, which can easily cause implant angle deviation. Repeated calibration is required during the implant process, which increases the operation time and poses a risk of accidental nerve injury. For this reason, we propose an oral implant positioning device. Summary of the Invention
[0005] The technical problem to be solved by this application is that the above-mentioned patent and existing positioning devices mostly use a handheld control device to extend the sensor into the oral cavity, which requires the patient to keep his mouth open. During long-term positioning, the patient's mouth is prone to shaking, resulting in positioning drift. The doctor needs to hold the control device in one hand and perform the implant operation with the other hand, which can easily cause implant angle deviation. Repeated calibration is required during the implant process, which increases the operation time and poses a risk of accidental nerve injury.
[0006] In order to solve the above technical problems, an embodiment of the present application provides an oral implant positioning device, including a brace, wherein special-shaped guide rails are provided on both sides of the inside of the brace, the brace and the special-shaped guide rails are connected by a clamping piece, and the inner sides of the special-shaped guide rails on both sides are slidably connected with sliders, and the bottoms of the sliders on both sides are installed with sensors located on the outside and inside of the teeth respectively, and a rotating drum located on the top of the teeth is provided between the sliders on both sides, and a through hole located in the rotation area of the rotating drum is opened on the top of the brace, and an angle adjustment mechanism for driving the rotating drum to rotate horizontally or vertically is connected between the sliders on both sides.
[0007] In some embodiments, the fastening member includes multiple sub-shorts, female buckles and rubber buckles, and multiple sub-shorts are equidistantly embedded on both sides of the braces, and multiple female buckles are equidistantly embedded on the outside of the special-shaped guide rails on both sides.

DETAILED DESCRIPTION
[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] Example 1: Please refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 The present invention provides a technical solution: an oral implant positioning device, comprising a brace 1, special-shaped guide rails 3 are provided on both sides of the inside of the brace 1, and sliders 4 are slidably connected to the inner sides of the special-shaped guide rails 3 on both sides, and sensors 5 located on the outside and inside of the teeth are installed at the bottom of the sliders 4 on both sides, and a rotating cylinder 7 located on the top of the teeth is provided between the sliders 4 on both sides. A through hole 101 is opened on the top of the brace 1 in the rotation area of the rotating cylinder 7, and an arc chamfer is provided at the edge of the through hole 101 on the top of the brace 1.
[0020] During specific implementation, the braces 1 are selected in a size that can be worn by most patients. The braces 1 can be customized according to the patient's oral condition. For edentulous patients, periosteal support nail holes are added to the bottom of the braces 1 to prevent displacement of the braces 1 during surgery.
[0021] During specific implementation, the special-shaped guide rail 3 needs to take into account both rigid support and biocompatibility, and adopts an internal metal alloy and an external PEEK material. The special-shaped guide rail 3 is internally provided with a driving device for driving the slider 4. Specifically, a micro servo motor can be selected to drive the synchronous wheel to drive the synchronous belt, and the synchronous belt can be connected to the slider 4.
[0022] The through hole 101 is provided so that the drill needle can pass through the brace 1 and enter the rotating drum 7 at different positions. The arc chamfer reduces friction resistance and avoids friction between the drill needle and the edge of the through hole 101 of the brace 1 when entering the rotating drum 7.
[0023] Compared with the handheld device, the brace 1 is directly mounted on the outside of the patient's implanted tooth, and the sliding cooperation of the special-shaped guide rail 3 and the slider 4 drives the sensors 5 located on the inside and outside of the tooth to scan synchronously, which enables the patient to close the mouth during scanning, avoiding the fatigue of the mandibular joint caused by the traditional handheld operation requiring the patient to open the mouth for a long time, and significantly improving the comfort of the patient and the doctor. Secondly, the rotating cylinder 7 is used as a rigid channel for the implant drill, and the angle of the rotating cylinder 7 is adjusted by the angle adjustment mechanism 6, which can achieve the fixing of the angle during implantation, avoiding the need for repeated calibration during traditional implantation.
[0024] An angle adjustment mechanism 6 for driving the rotating drum 7 to rotate horizontally or vertically is connected between the sliders 4 on both sides. The angle adjustment mechanism 6 includes a first motor 601 installed on the inner side of the slider 4 on one side, and the output end of the first motor 601 is connected to a rotating ring 602 movably sleeved on the outer side of the rotating drum 7. A fixed block 603 is installed on the side of the rotating ring 602 away from the first motor 601, and a rotating plate 604 is rotatably connected between the fixed block 603 and the slider 4 on the other side. The angle adjustment mechanism 6 also includes a second motor 605 installed on the top of the fixed block 603, and the output end of the second motor 605 extending into the interior of the fixed block 603 is connected to a pulley 606. The inner side of the rotating ring 602 is rotatably connected to a belt ring 607, which is fixedly sleeved on the outer side of the rotating drum 7. The outer side tensioning sleeves of the belt ring 607 and the pulley 606 are provided with belts 608, and the outer sides of the fixed block 603 and the rotating ring 602 are provided with through holes for the belt 608 to pass through.
[0025] It should be noted that in order to prevent the patient's saliva from penetrating into the sensor 5, the drive device, the first motor 601 and the second motor 605 when the mouth is closed, a waterproof sealing design is required. This is an existing structure and will not be described in detail.
[0026] Example 2: Based on Example 1, Figure 3 and Figure 4 As shown, the braces 1 and the special-shaped guide rail 3 are connected by a clamping piece 2, which includes a plurality of sub-snaps 201, a female buckle 202 and a rubber buckle 203. The plurality of sub-snaps 201 are equidistantly embedded on both sides of the inside of the braces 1, and the plurality of female buckles 202 are equidistantly embedded on the outside of the special-shaped guide rails 3 on both sides. It also includes rubber buckles 203 embedded at both ends of the outside of the special-shaped guide rail 3 on one side. Both ends of the inner side of the braces 1 are provided with a card groove adapted to the size of the rubber buckle 203. The shape of the rubber buckle 203 is mushroom-shaped, and an arc-shaped buffer hole 2031 is provided in the middle of the rubber buckle 203.
[0027] The sub-buckle 201 and the female buckle 202 are designed to be equidistantly embedded to form a grid anchor point, which disperses the shear stress caused by the bite impact and avoids the local stress concentration caused by traditional bolts. The arc-shaped buffer hole 2031 is used to realize the deformation of the position of the rubber buckle 203 after extrusion. The double insurance fixation method of the sub-buckle 201, the female buckle 202 and the rubber buckle 203 is adopted to increase the stability of the special-shaped guide rail 3 after installation.
[0028] In combination with the above embodiments, the following is the entire working principle of the above embodiments: when in use, align the sub-buckle 201, the female buckle 202, the rubber buckle 203 and the card slot to fix the special-shaped guide rail 3 and the braces 1, and then put the braces 1 on the outside of the tooth to be implanted, start the driving device on the special-shaped guide rail 3 to realize the movement of the slider 4, and when the slider 4 moves, it drives the sensor 5 to scan the outside and inside of the tooth. When scanning to the implantation area, turn off the driving device, start the first motor 601, and drive the rotating drum 7 to rotate longitudinally through the rotating ring 602. Start the second motor 605 to drive the pulley 606 to rotate, and drive the belt ring 607 and the rotating drum 7 to rotate horizontally through the belt 608, so that the rotating drum 7 is adjusted to the required implantation angle, and use a drill to pass through the through hole 101 at the top of the braces 1 and the rotating drum 7 to implement the implantation operation.
