[0002] Dentures are artificial teeth that are used to replace original teeth when teeth are missing to provide chewing and aesthetic functions. Generally, when a patient has a small number of missing teeth in their mouth, a corresponding denture can be inserted in the missing area; when a patient has a large number of missing teeth in their mouth, a full-mouth digital removable denture is needed for restoration. Full dentures can be understood as personalized, customized dentures that are made according to the actual conditions in the patient's mouth. Compared to ordinary dentures, the biggest advantage of full dentures is that they fit well and can perfectly match the patient's gums.

[0003] In the process of producing full dentures, the corresponding base assembly and multiple tooth units are generally produced first, and then the multiple tooth units are fixed to the base assembly in sequence with adhesives, thereby forming a complete and personalized full denture. It is understandable that there is an ideal fixed position and fixed angle between each tooth unit and the base assembly. However, in the prior art, after the base assembly and multiple tooth units are produced, the technicians generally install the multiple tooth units one by one and glue them to the base assembly based on their personal experience. Such an operation process is very easy to introduce deviations, making it difficult to achieve the ideal fixed position and fixed angle between the tooth units and the base assembly, which in turn causes some tooth units to not fully match the patient's oral conditions, affecting the fit of the removable denture.

[0050] To make the purpose, technical solutions and advantages of the present application clearer and more explicit, the present application is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0051] In view of the fact that the prior art cannot guarantee that each tooth monomer and the base assembly are in an ideal fixed position and fixed angle when manufacturing a complete denture, the present application provides a digital complete denture manufacturing module and manufacturing method.

[0052] As shown in Figure 1 and Figure 2 A digital complete denture manufacturing module, which comprises a fixed seat assembly 1, a base assembly 2, tooth monomers 3, and a positioner 4, the tooth monomers 3 are provided in multiple, the multiple tooth monomers 3 form a dentition, the fixed seat assembly 1, the base assembly 2, the tooth monomers 3, and the positioner 4 are arranged from bottom to top, that is, the base assembly 2 is arranged on the fixed seat assembly 1, the tooth monomers 3 are arranged on the base assembly 2 below, and the positioner 4 is sleeved on the tooth monomers 3 above. Among them, the fixed seat assembly 1 mainly plays a structural support role, the base assembly 2 is used to fix the tooth monomers 3, the tooth monomers 3 are single teeth, and the positioner 4 mainly plays a role in assisting to determine the optimal fixed position and fixed angle of the tooth monomers 3 on the base assembly 2.

[0053] In the present application, the upper surface of the fixed seat assembly is provided with a base plate protruding part 101, which corresponds to the patient's gum, and the shape and size of the base plate protruding part 101 are consistent with the patient's gum. Correspondingly, the lower surface of the base plate assembly is provided with a fixed groove corresponding to the shape and size of the base plate protruding part 101. The base plate assembly is sleeved on the fixed seat assembly through the mutual cooperation between the fixed groove and the base plate protruding part 101. Therefore, after the completion of the production, the base plate assembly can be exactly nested on the patient's gum through the fixed groove thereon. The upper surface of the base plate assembly is provided with a plurality of tooth mounting grooves 201, and the tooth mounting grooves 201 correspond to the tooth monomers one by one. A plurality of tooth monomers are arranged in the tooth mounting grooves respectively. In order to better bond the tooth monomers, the lower surface of the locator is provided with a plurality of tooth positioning grooves for fixing the position and direction of the tooth monomers.

[0054] The process of making a complete set of dentures based on the above-mentioned complete set of digital denture making modules is as follows: first, the base plate assembly is fixed on the fixed seat assembly through the cooperation of the fixed groove and the base plate protruding part. At this time, the tooth mounting groove opening in the base plate assembly faces upward. Second, the locator is turned over so that the tooth mounting groove opening faces upward, and a plurality of tooth monomers are sleeved into the corresponding tooth mounting grooves one by one. It should be noted that the size of the tooth mounting groove is slightly smaller than the size of the corresponding tooth monomer. After loading is completed, when the tooth mounting groove opening faces downward, each tooth monomer will not fall out of it. Then, the locator is turned over again so that each tooth monomer is sleeved into the corresponding tooth mounting groove, and is slightly adjusted so that each tooth monomer is in the best fixed position and fixed angle, thereby avoiding the position and angle deviation caused by bonding the tooth monomers one by one in the prior art.

[0055] In the prior art, there is no such key component as the locator. After the fixed seat assembly, the base plate assembly and the tooth monomers are made, the base plate assembly is placed on the fixed seat assembly, and then the tooth monomers are placed on the base plate assembly one by one. Then, the position and angle between the tooth monomers and the base plate assembly are adjusted according to experience, and then the tooth monomers are bonded to the base plate assembly. It can be understood that in this process, the operation experience of the technician is not completely reliable, which may cause deviation of some or all tooth monomers. The locator in the present application can avoid this problem.

[0056] The lower surface of the locator is provided with a plurality of tooth positioning grooves, the locator fixes the position and direction of each tooth monomer through the tooth positioning grooves from top to bottom, when the tooth monomer is sleeved into the tooth positioning groove, the relative position between each tooth monomer is fixed and optimal, after the plurality of tooth monomers are placed on the base assembly through the locator, as long as one tooth monomer is not in place, other tooth monomers cannot be in place. At this time, only the matching position between the locator and the base assembly needs to be adjusted slightly, according to the positional relationship between the entire dentition and the base assembly, the optimal installation mode can be determined conveniently and quickly, so that all tooth monomers are in the optimal fixed position and fixed angle.

[0057] In general, each tooth monomer is first placed into the tooth positioning groove in the locator, and the plurality of tooth monomers form a complete dentition in the locator, and then the plurality of tooth monomers are placed on the base assembly through the locator, and the fixed position and fixed angle between the tooth monomer and the base assembly are adjusted by means of the locator, so as to eliminate the deviation.

[0058] As shown in Figure 2 and Figure 3 Preferably, the locator 4 comprises a crown wall 401, a lingual wall 402 and a labial wall 403, the lingual wall 402 and the labial wall 403 are respectively arranged on both sides of the crown wall 401, and the tooth positioning groove is formed between the crown wall 401, the lingual wall 402 and the labial wall 403.

[0059] The crown wall 401, the lingual wall 402 and the labial wall 403 are provided with observation through holes 404. When the tooth monomer 3 is placed in the tooth positioning groove, it is most ideal that the outer wall of the tooth monomer 3 completely abuts against the inner wall of the tooth positioning groove. Therefore, the observation through holes 404 are arranged on the crown wall 401, the lingual wall 402 and the labial wall 403, the positioning of the tooth monomer 3 is checked through the observation through holes 404, and the positional deviation of the tooth monomer 3 is prevented.

[0060] In addition, the observation through hole also has the effect of assisting in taking out the locator. As described above, in order to prevent each tooth monomer from falling off from the tooth mounting groove when the tooth mounting groove opening faces downward, the size of the tooth mounting groove is slightly smaller than the size of the corresponding tooth monomer, and such design makes the tooth monomer have a certain probability of being stuck in the tooth mounting groove and being difficult to take out. At this time, after the bonding is completed, a slender hard rod is inserted into the observation through hole, so that the tooth monomer can be easily loosened, thereby facilitating the separation of the locator and each tooth monomer after the bonding of all tooth monomers is completed.

[0061] Preferably, a snap-fit ​​portion is provided on the inner side of the crown wall, and the snap-fit ​​portion matches the crown of the tooth unit. It is conceivable that the surface of the crown may have a certain uneven texture. By providing a snap-fit ​​portion on the inner side of the crown wall that matches the crown, when the tooth unit is placed in the tooth mounting groove, the snap-fit ​​portion will engage with the surface of the crown, thereby achieving alignment and preventing deviation between the tooth unit and the locator.

[0062] exist Figure 1 and Figure 2 In the corresponding embodiment, the positioner only covers the individual tooth units and not the base assembly. Therefore, when adjusting the relative position of each tooth unit and the base assembly using the positioner, it is necessary to try multiple matching solutions. When each tooth unit is inserted into the tooth positioning groove and does not shake even slightly, it can be determined that this is the optimal installation method. However, this positioning method cannot quickly and accurately find the optimal installation method.

[0063] like Figure 3 As shown, preferably, in order to quickly and accurately find the best installation method, the positioner 4 is also provided with a first wrapping portion 405 and a second wrapping portion 406, the first wrapping portion 405 is provided on the edge of the lingual side wall 402, and the second wrapping portion 406 is provided on the edge of the labial side wall 403, and the first wrapping portion 405 and the second wrapping portion 406 abut against the base assembly 2.

[0064] Through the cooperation between the base assembly and the first wrapping part and the second wrapping part, with the base assembly as the reference point for alignment, it is only necessary to insert the locator provided with the first wrapping part and the second wrapping part into the base assembly, and make the first wrapping part and the second wrapping part wrap the base assembly, so as to conveniently and quickly determine the optimal position of the tooth unit.

[0065] In addition, a plurality of bonding windows are provided on the first wrapping portion and / or the second wrapping portion, so that a technician can bond the tooth monomer through the bonding windows.

[0066] like Figure 2 As shown, preferably, the fixing seat assembly is provided with at least one positioning protrusion 102, and the base assembly is provided with at least one positioning recess 202. The positioning protrusions 102 correspond to the positioning recesses 202 one by one, and the positioning protrusions 102 are locked in the positioning recesses 202. The cooperation between the positioning protrusions and the positioning recesses allows the base assembly to be better fixed to the fixing seat assembly, preventing the base assembly from being displaced relative to the fixing seat assembly during the production of the complete denture, thereby affecting the installation of the tooth monomer.

[0067] Specifically, the positioning protrusions are provided with three, three positioning protrusions are located on the left side, the middle and the right side of the fixed seat assembly respectively; the positioning recesses are provided with three, three positioning recesses are located on the left side, the middle and the right side of the base plate assembly respectively. The left side, the middle and the right side are respectively provided with a group of positioning protrusions and positioning recesses, which can further improve the fixing effect between the base plate assembly and the fixed seat assembly.

[0068] Preferably, the lower surface of the fixed seat assembly is provided as a flat surface. The flat surface is provided on the lower surface of the fixed seat assembly, which facilitates the placement of the entire manufacturing module on the operation table.

[0069] The material of the base plate assembly and the tooth monomer is PMMA resin. PMMA resin has the advantages of chemical stability, non-toxicity and high strength, and can be used as a 3D printing material.

[0073] S3. Design a fixed seat model, a base plate model and a plurality of tooth monomer models based on the three-dimensional model of the patient's mouth. The fixed seat model, the base plate model and the plurality of tooth monomer models most matched with the three-dimensional model are designed according to the three-dimensional model; similarly, the fixed seat model, the base plate model and the plurality of tooth monomer models are virtual three-dimensional models.
