Description

Technical Field

[0001] This utility model relates to the field of dental treatment instruments, and in particular to a dental implant placement guide and positioner. Background Technology

[0002] In dental implant surgery, the implant placement guide plays a crucial role. It provides key guidance for accurate implant placement, ensuring that the implant's position, angle, and depth within the alveolar bone meet surgical requirements, thus significantly impacting the success rate of the implant surgery and the long-term stability of the implant.

[0003] Most existing dental implant placement guides employ a fixed structure design. Their mechanical structure typically consists of an integral frame and a fixed-size guide sleeve. The frame primarily provides fixation and support within the oral cavity, while the guide sleeve determines the implant's placement direction. Technically, they rely on pre-defined standard dimensions and shapes, maintaining stability through the contact between the frame and the surface of the teeth or alveolar bone. The implant is then inserted into the alveolar bone along a predetermined path via the guide sleeve.

[0004] However, traditional fixed-structure guide locators cannot be flexibly adjusted according to the actual size of the alveolar bone of different patients due to the large differences in length, height and width of the alveolar bone. The locator needs to be replaced, which is quite troublesome. Therefore, a new dental implant guide locator is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dental implant placement guide locator, which aims to improve the problem that the length of traditional guide locators in the prior art is fixed and cannot be adjusted.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A dental implant placement guide and locator includes a sleeve, an anti-slip pad fixedly connected to the side wall of the sleeve, a movable component disposed inside the sleeve, and a guide component disposed on the side wall of the sleeve.

[0008] The movable component includes a slide rod, the side wall of which is slidably connected to the inside of the sleeve. The sleeve has a first fixing hole inside, the slide rod has a second fixing hole inside, an insert rod is slidably connected inside the slide rod, a fixing block is fixedly connected to the side wall of the insert rod, a groove is provided inside the insert rod, a locking block is provided inside the insert rod, and a spring is provided inside the insert rod.

[0009] As a further description of the above technical solution:

[0010] The guide assembly includes a connecting rod, the sidewall of which is fixedly connected to the sidewall of the slide bar. The connecting rod is a malleable and deformable rod that can rotate or displace at multiple angles.

[0011] As a further description of the above technical solution:

[0012] A connecting block is fixedly connected to the side wall of the connecting rod, and a gap positioner is fixedly connected to the side wall of the connecting block;

[0013] As a further description of the above technical solution:

[0014] The gap positioner has a silicone pad fixedly connected inside. The silicone pad is made of medical-grade silicone rubber, which has excellent elasticity and softness.

[0015] As a further description of the above technical solution:

[0016] A silicone rubber ring is fixedly connected to the side wall of the gap positioner, and the silicone rubber ring is made of soft silicone.

[0017] As a further description of the above technical solution:

[0018] The side wall of the insertion rod is slidably connected inside the first fixing hole and the second fixing hole;

[0019] As a further description of the above technical solution:

[0020] The side wall of the card block is slidably connected inside the groove, and the side wall of the card block is in contact with the side wall of the slide rod;

[0021] As a further description of the above technical solution:

[0022] One end of the spring is fixedly connected inside the groove, and the other end of the spring is fixedly connected to the bottom of the card block.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, pulling the fixing block causes the insertion rod to move, the locking block is squeezed into the groove by the sliding rod, the insertion rod is pulled out and the sliding rod loses its fixation, and the sliding rod is pulled out to slide in the sleeve for length adjustment. This solves the problem of the fixed and non-adjustable length of the traditional guide locator. The above technical solution improves the applicability of the guide locator in oral implant surgery for different patients.

[0025] 2. In this utility model, after the connecting rod is twisted into the required shape, the gap locator is placed at the implantation site by holding the sleeve. The silicone rubber ring on the side wall of the gap locator is made of soft silicone, and the silicone pad inside is made of medical silicone rubber. This solves the problem that traditional fixed-shape locators are difficult to adapt to complex oral environments and implants of different diameters. The above technical solution improves the smoothness and efficiency of surgical operation. Attached Figure Description

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0033] Reference Figure 1 - Figure 4This utility model provides an embodiment of a dental implant placement guide and locator, comprising a sleeve 1, with an anti-slip pad 2 fixedly connected to the side wall of the sleeve 1. The anti-slip pad 2 increases the friction between the hand and the sleeve 1. A moving component is provided inside the sleeve 1, and a guiding component is provided on the side wall of the sleeve 1. The moving component includes a slide rod 4, which is slidably connected to the side wall of the sleeve 1. A fixing hole 3 is provided inside the sleeve 1, and a fixing hole 5 is provided inside the slide rod 4. An insertion rod 6 is slidably connected inside the slide rod 4. A fixing block 7 is fixedly connected to the side wall of the insertion rod 6. A groove 8 is provided inside the insertion rod 6. A locking block 9 is provided inside the insertion rod 6 to fix the slide rod 4. A spring 10 is provided inside the insertion rod 6 to rebound and reset. The side wall of the insertion rod 6 is slidably connected to the inside of fixing hole 3 and fixing hole 5. The side wall of the locking block 9 is slidably connected to the inside of the groove 8. The side wall of the locking block 9 fits against the side wall of the slide rod 4. One end of the spring 10 is fixedly connected to the inside of the groove 8, and the other end of the spring 10 is fixedly connected to the bottom of the locking block 9.

[0034] The alveolar bone varies greatly in length, height, and width among different patients. Firstly, pulling the fixing block 7 moves the insert rod 6. The insert rod 6 acts as a transmission component, transferring the external force on the fixing block 7 to the locking block 9. When the insert rod 6 moves, the locking block 9 is compressed by the sliding rod 4. The locking block 9 plays a crucial role in locking and unlocking; its shape matches the sliding rod 4 and the groove 8, allowing it to restrict the position of the sliding rod 4 under certain conditions. When compressed, the locking block 9 enters the groove 8, which provides space for it to move smoothly and release its restraint from the sliding rod 4. During this process, the locking block 9 compresses the spring 10, causing it to contract. The spring 10 has the characteristic of storing elastic potential energy. When the insert rod 6 is pulled out, the sliding rod 4 loses the fixing effect of the locking block 9. At this time, the slide bar 4 can slide inside the sleeve 1. The sleeve 1 provides a sliding track and support structure for the slide bar 4. The length of the guide locator can be adjusted by sliding the slide bar 4 inside the sleeve 1, thereby adapting to the differences in the length direction of the alveolar bone of different patients. After adjusting to the required length, the insert bar 6 is inserted into the slide bar 4 again. When the insert bar 6 moves again, the locking block 9 will repeat the previous action, that is, enter the groove 8 again and squeeze the spring 10. When one end of the insert bar 6 is inserted out of the slide bar 4, the locking block 9 loses the squeezing from the slide bar 4. At this time, the spring 10 uses the elastic potential energy stored before to rebound and lock the locking block 9 into the side wall of the slide bar 4, fixing the slide bar 4, thereby fixing the adjusted length of the guide locator, ensuring that the guide locator can play a stable role in the oral implantation surgery, and providing a reliable length guarantee for the accurate implantation of the implant.

[0035] Reference Figure 1 - Figure 4The guiding assembly includes a connecting rod 11, the side wall of which is fixedly connected to the side wall of the slide rod 4. The connecting rod 11 is a malleable and deformable rod that can rotate or shift at multiple angles to adapt to the implantation path angle requirements of implants in different patients' oral cavity. A connecting block 12 is fixedly connected to the side wall of the connecting rod 11, and a gap locator 13 is fixedly connected to the side wall of the connecting block 12. A silicone pad 14 is fixedly connected inside the gap locator 13. The silicone pad 14 is made of medical-grade silicone rubber, which has excellent elasticity and softness. The silicone pad 14 can elastically deform according to implants of different diameters and fit tightly to the implant surface. A silicone rubber ring 15 is fixedly connected to the side wall of the gap locator 13. The silicone rubber ring 15 is made of soft silicone.

[0036] According to the requirements, the connecting rod 11 is twisted into the required shape. The connecting rod 11 is a malleable and deformable rod with special material properties and structural design, which can rotate or shift at multiple angles. Its rotatable characteristics allow for flexible adjustment of direction in the complex three-dimensional space of the oral cavity. Whether it is a change in angle in the horizontal direction or an adjustment in tilt in the vertical direction, it can be achieved, thereby adapting to the implantation path angle requirements of different patients' intraoral implants. Then, holding the sleeve 1, the space locator 13 is placed at the site where the implant needs to be implanted. The sleeve 1 has an anti-slip pad 2 fixed on its side wall. The anti-slip pad 2 is made of a material with a high coefficient of friction. When the doctor holds the sleeve 1, the anti-slip pad 2 can increase the friction between the hand and the sleeve 1, so that the doctor can hold the sleeve 1 more firmly during the operation and avoid the space locator 13 from slipping in the oral cavity. The position of the gap locator 13 is shifted, thus ensuring that the gap locator 13 can be accurately placed at the predetermined implantation site, laying the foundation for the precise positioning of subsequent implantation. A silicone rubber ring 15 is fixed to the side wall of the gap locator 13. The silicone rubber ring 15 is made of soft silicone, which has good flexibility and biocompatibility. When it comes into contact with the oral cavity wall, its soft texture can adapt to the irregular shape of the oral cavity wall and evenly distribute the contact pressure, thereby reducing the stimulation of the oral nerves. At the same time, a silicone pad 14 is fixed inside the gap locator 13. The silicone pad 14 is made of medical silicone rubber, which has excellent elasticity and softness. This characteristic allows the silicone pad 14 to elastically deform according to implants of different diameters, tightly adhering to the implant surface, providing stable support and positioning for the implant.

[0037] Working principle: Different patients have significant differences in the length, height, and width of their alveolar bone. By pulling the fixing block 7, the insertion rod 6 is moved. The movement of the insertion rod 6 causes the locking block 9 to be squeezed into the groove 8 by the sliding rod 4, which in turn compresses the spring 10 and causes it to contract. After the insertion rod 6 is pulled out, the sliding rod 4 loses its fixation. The sliding rod 4 can be pulled out to slide inside the sleeve 1 to adjust its length. After adjustment, the insertion rod 6 is inserted into the sliding rod 4 again, and the locking block 9 enters the groove 8 again to compress the spring 10. When one end of the insertion rod 6 is inserted out of the sliding rod 4, the locking block 9 loses its compression, and the spring 10 rebounds to lock the locking block 9 into the side wall of the sliding rod 4 to fix it.

[0038] According to the requirements, the connecting rod 11 is twisted into the required shape. The connecting rod 11 is a malleable and deformable rod that can rotate or shift at multiple angles. Then, holding the sleeve 1, the gap locator 13 is placed on the site where the implant needs to be inserted. The sleeve 1 has an anti-slip pad 2 fixed on its side wall, and the gap locator 13 has a silicone rubber ring 15 fixed on its side wall. The silicone rubber ring 15 is made of soft silicone, which can reduce the stimulation of the nerves in the oral cavity when it comes into contact with the oral cavity wall. At the same time, a silicone pad 14 is fixed inside the gap locator 13. The silicone pad 14 is made of medical silicone rubber, which has excellent elasticity and softness and can fit implants of different diameters very well.
