[0002] Teeth are the main tool for humans to chew food. Damage to teeth can lead to loss of chewing function, difficulty in breaking food, and seriously reduce the quality of life. Dental implants are a means of dental treatment used to replace missing teeth. Dental implants mainly include implants and temporary dentures. Implants, also known as artificial tooth roots, are implanted in the maxillary or mandibular part of the human body where the teeth are missing. Temporary dentures are connected to implants. Their main function is to assume temporary functions, aesthetics, and protection, which is conducive to the smooth placement of the final restoration and the reshaping of the gingival soft tissue with the help of temporary restorations.

[0003] With the development of digital technology, digital oral scanning technology, computer-aided design and computer-aided manufacturing technology are rapidly applied in the dental implant industry. According to the individual conditions of different patients, personalized implant plans are designed using visual computer-aided technology before surgery, and digital guides are produced in combination with computer-aided manufacturing. In related technologies, digital guides are substrates placed in the patient's mouth. Among them, the temporary denture is provided with pillars, which are used to position and cooperate with the substrate.

[0004] However, after the operation is completed, the temporary denture with the pillars needs to be taken out, the pillars need to be ground off outside the patient's mouth, and the surface needs to be processed to be smooth, which increases the number of steps in the operation, increases the operation time, and reduces the efficiency of the operation.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] like Figures 1 to 3 As shown, an embodiment of the utility model provides a positioning device for denture implantation, the positioning device for denture implantation includes a positioning base plate 10 and a denture mounting plate 20, the positioning base plate 10 has a denture accommodating groove 11; the denture mounting plate 20 is removably covered on the positioning base plate 10, the denture mounting plate 20 has an implant avoidance groove 21 and a denture connecting portion, when the denture mounting plate 20 is covered on the positioning base plate 10, the implant avoidance groove 21 corresponds to the denture accommodating groove 11, and the positioning base plate 10 and the denture mounting plate 20 are positioned and matched.

[0032] By applying the technical solution of the utility model, the positioning device for denture implantation includes a positioning base plate 10 and a denture mounting plate 20. The positioning base plate 10 is installed in the patient's oral cavity, and the temporary denture 1 is connected to the denture mounting plate 20 through the denture connection part. The denture mounting plate 20 is covered on the positioning base plate 10 so that the implant avoidance groove 21 corresponds to the denture receiving groove 11. The temporary denture 1 is transferred to the denture receiving groove 11, and the denture mounting plate 20 is taken out from the positioning base plate 10, so that the temporary denture 1 can be installed. Compared with the temporary denture positioning and installation method in the related art, the positioning device for denture implantation does not need to set a pillar for the temporary denture 1, thereby eliminating the grinding process of the pillar, reducing the surgical steps, shortening the surgical time, and improving the surgical efficiency.

[0033] The positioning substrate 10 is installed in the oral cavity and can directly contact the patient's oral mucosa or bone, and plays the most important basic part in the operation. Except for the installation of the temporary denture 1, the rest of the surgical steps can be completed based on the positioning substrate 10.

[0034] In this embodiment, if Figure 4 As shown, the temporary denture 1 has an avoidance groove for avoiding the implant, which is designed in advance before the operation. The positioning device used for denture implantation can better match the corresponding position of the implant and restore the height of the temporary denture when it is designed.

[0035] Specifically, the denture connection part is located on a side of the denture mounting plate 20 close to the positioning base plate 10. The denture mounting plate 20 is snap-fitted with the temporary denture 1 through the denture connection part.

[0036] Among them, the temporary denture 1 is generally made of resin material, and its main function is to assume temporary functions, aesthetics, and protection, which is conducive to the smooth placement of the final restoration and the reshaping of the gingival soft tissue with the help of the temporary restoration. The implant is implanted into the upper and lower jaws of the toothless part of the human body through surgery. After the surgical wound heals, a device for repairing the denture is installed on its upper part.

[0037] like Figure 2 As shown, the denture mounting plate 20 includes a plate body 22 and a connecting column 23 connected to the outer wall of the plate body 22. The implant avoidance groove 21 and the denture connection part are both arranged on the plate body 22. When the denture mounting plate 20 is covered on the positioning base plate 10, the connecting column 23 is positioned and matched with the positioning base plate 10. The denture mounting plate 20 with the above structure uses the connecting column 23 to position and match with the positioning base plate 10, and uses the connecting column 23 to form a connection space for the temporary denture 1 between the positioning base plate 10 and the plate body 22, which has the advantage of simple structure.

[0038] like Figure 3 As shown, the positioning substrate 10 is provided with a first connection part 12, and the connection column 23 is provided with a second connection part 24. The first connection part 12 and the second connection part 24 are positioned and matched and detachably connected. The above matching structure has the advantages of simple structure and easy setting.

[0039] The first connection part 12 and the second connection part 24 can be configured as arc structures and respectively match the shapes of the positioning substrate 10 and the plate body 22. At this time, the first connection part 12 and the second connection part 24 can respectively be configured as a single component, such as a plug section and a plug slot.

[0040] like Figure 5As shown, in one embodiment, the first connecting portion 12 includes a first magnet, and the second connecting portion 24 includes a second magnet that can be magnetically matched with the first magnet. The magnetic matching method has the advantages of simple structure and easy operation.

[0041] Among them, one of the first magnet and the second magnet can be set as a magnet, and the other can be set as a metal such as iron, cobalt, and nickel that can be adsorbed by the magnet. Of course, both can also be set as magnets.

[0042] like Figure 6 As shown, in another embodiment, one of the first connection part 12 and the second connection part 24 is a clamping column 121, and the other of the first connection part 12 and the second connection part 24 is a clamping tube 241. The clamping tube 241 has a plurality of open grooves arranged at intervals along its circumference, and the clamping column 121 is inserted into the clamping tube 241. The matching structure in which the clamping column 121 and the clamping tube 241 are clamped together has the advantage of stable positioning.

[0043] The opening groove passes through the end surface of the clamping tube 241. When the clamping column 121 is inserted into the clamping tube 241, the clamping tube 241 undergoes elastic deformation and emits a "click" sound, and this click structure can serve as a reminder that the denture mounting plate 20 and the positioning base plate 10 have been installed in place.

[0044] like Figure 7 As shown, in other embodiments, one of the first connection part 12 and the second connection part 24 is a plug-in column 122, and the other of the first connection part 12 and the second connection part 24 is a plug-in tube 242. The outer diameter of the plug-in column 122 gradually decreases in the direction close to the plug-in tube 242, and the plug-in column 122 is inserted in the plug-in tube 242. The structure of the plug-in column 122 and the plug-in tube 242 being plugged in and matched has the advantage of being easy to operate.

[0045] like Figures 5 to 7 As shown, there are multiple first connection parts 12 and multiple second connection parts 24, and the multiple first connection parts 12 are arranged one by one with the multiple second connection parts 24, and the multiple first connection parts 12 are respectively located on both sides of the denture receiving groove 11. The multiple first connection parts 12 and the multiple second connection parts 24 are matched to ensure stable positioning and facilitate the transfer of the temporary denture 1 to the denture receiving groove 11.

[0046] like Figure 2 and Figure 3 As shown, the denture accommodating groove 11 is an arc-shaped groove, the plate body 22 is an arc-shaped plate, the arc-shaped plate is adapted to the arc-shaped groove, there are multiple implant avoidance grooves 21, and the multiple implant avoidance grooves 21 are arranged at intervals along the extension direction of the plate body 22. The above-mentioned arc-shaped structure can make the denture accommodating groove 11, the plate body 22 and the temporary denture 1 adapted to the shape of the oral cavity, thereby enhancing the aesthetics.

[0047] In this embodiment, the connecting column 23 is a curved structure that is away from the plate body 22 in the radial direction of the plate body 22. With the above structure, space can be reserved for the connection between the temporary denture 1 and the plate body 22.

[0048] like Figure 3 As shown, the positioning substrate 10 includes an inner arc plate 13, an outer arc plate 14 and two connecting plates 15, the inner arc plate 13 is located inside the outer arc plate 14, the end of the inner arc plate 13 is connected to the corresponding end of the outer arc plate 14 through the connecting plate 15, the outer side wall of the inner arc plate 13, the inner side wall of the outer arc plate 14 and the inner side walls of the two connecting plates 15 together form a denture receiving groove 11, when the denture mounting plate 20 is covered on the positioning substrate 10, the inner arc plate 13 and the outer arc plate 14 are both positioned and matched with the denture mounting plate 20. The positioning substrate 10 adopting the above structure has the advantages of simple structure and easy processing.

[0049] like Figure 3 As shown, the positioning substrate 10 further includes a reinforcing plate 16, and both ends of the reinforcing plate 16 are respectively connected to the inner side walls of the inner arc plate 13. The reinforcing plate 16 can increase the structural strength of the positioning substrate 10, thereby preventing the positioning substrate 10 from being deformed.

[0050] Specifically, the positioning base plate 10 and the denture mounting plate 20 are both manufactured by 3D printing. By adopting the above manufacturing process, digital design and digital manufacturing can be realized, which is more in line with the actual situation of the patient.

[0051] The positioning substrate 10 is provided with an oral positioning portion 17. The oral positioning portion 17 is used to facilitate fixing the positioning substrate 10 in the oral cavity.

[0052] In this embodiment, the oral cavity positioning portion 17 is a fixing nail hole provided on the positioning substrate 10 , and the fixing nail passes through the fixing nail hole to fix the positioning substrate 10 in the patient's oral cavity.
