Technical Field

[0001] The present application relates to the technical field of denture processing, and in particular to a denture and a digital combined removable denture processing method. Background Art

[0002] Dentures are mainly used to replace and perform the functions of missing natural teeth. They use the remaining natural teeth, the mucosa and bone tissue under the base as support, rely on the denture's retainers and base for retention, use artificial teeth to restore the shape and function of missing teeth, and use base materials to restore the defective alveolar ridge, jawbone and its surrounding soft tissue morphology. Patients can remove and put on a restoration by themselves.

[0003] The prior art discloses a denture processing method, which includes S1: using alginate or silicone rubber and other impression materials to take a patient's impression; S2: after taking the impression, pouring a plaster model and putting it on a frame; S3: marking the plaster model, spreading wax and other processes to complete the bracket wax model; S4: embedding and casting the prepared bracket wax model to obtain a metal bracket; S5: grinding and polishing the bracket after embedding and casting; S6: placing the bracket on the model for manual tooth arrangement; S7: packing the arranged teeth into a box and filling them with glue; S8: opening the box and grinding after filling with glue to complete the denture production.

[0004] Regarding the above-mentioned related technologies, in the process of denture production, there are many steps involving manual participation, and operations such as wax casting, tooth arrangement and filling, and box opening and polishing will have a great impact on the accuracy of the denture, resulting in high labor costs and making the quality of the denture difficult to control. Summary of the invention

[0005] In order to improve the processing quality of dentures while reducing labor costs, the present application provides a denture and a digital combined removable denture processing method.

[0006] The present application provides a method for processing a denture and a digital combined removable denture using the following technical solutions:

[0007] In a first aspect, the present application discloses a method for processing a digital combined removable denture, comprising:

[0008] S1: Oral data collection: collect the original data A of the target user's oral cavity, including the shape, size and position information of the teeth, gums and oral soft tissues;

[0009] S2: Data processing: Process the collected raw data A to obtain processed data B, and generate individual three-dimensional data C of the bracket and the tooth based on the processed data B, and generate the overall three-dimensional data D of the bracket, denture and base at the same time;

[0010] S3: Bracket and tooth processing: According to the individual three-dimensional data C of the bracket and the tooth, the bracket is processed on the metal block by using a subtractive manufacturing method, and the tooth is processed;

[0011] S4: Assembly and filling: Connect the tooth and the bracket to obtain a composite body, and fill the cutting position of the composite body and the metal block with resin to combine the resin with the composite body;

[0012] S5: Secondary processing: Cutting the resin and the assembly according to the overall three-dimensional data D until the three-dimensional dimensions of the resin and the assembly are consistent with the overall three-dimensional data D.

Through subtractive manufacturing, the coordinate system can be kept consistent before and after the denture processing, avoiding the step of model comparison after the processing is completed, reducing the links of manual carving and polishing, improving production efficiency and reducing labor production costs.

[0014] In a specific possible implementation scheme, in step S4, a raised column is integrally formed on the bracket, and a clearance groove adapted to the raised column is formed on the tooth, and the bracket and the tooth are reinforced by mortise and tenon joints through the cooperation of the raised column and the clearance groove.

[0015] By adopting the above technical solution, the mortise and tenon joints between the bracket and the tooth can be reinforced through the cooperation of the raised column and the clearance groove, thereby improving the connection stability between the bracket and the tooth.

[0016] In a specific implementation manner, in step S4, the bracket and the tooth are bonded using a self-curing resin.

[0021] S51: Main body cutting: According to the overall three-dimensional data D, the resin and the assembly are cut until they are consistent with the overall three-dimensional data D, so as to obtain a rough denture blank;

[0022] S52: Grinding and polishing: Grind, polish and disinfect the rough denture to obtain the final denture.

[0023] By adopting the above technical solution, the denture rough blank can be further ground and polished after being obtained by cutting, thereby improving the product quality of the denture and the user experience.

[0024] In a specific possible implementation, in step S3, a computer numerically controlled machine tool is used to complete the subtractive manufacturing of the bracket.

[0025] By adopting the above technical solution, the automated processing of the bracket subtractive manufacturing can be realized, which reduces the labor cost and improves the processing accuracy of the bracket.

[0026] In a specific implementation scheme, in step S1, an oral scanner is used to collect raw data A of the target user's oral cavity.

[0027] By adopting the above technical solution, the original oral data A of the target user can be collected, which is convenient for improving the three-dimensional reference for the later denture processing and improving the matching degree between the denture and the user's oral cavity.

[0028] In a second aspect, the present application discloses a modular removable denture manufactured using a digital modular removable denture processing method.

[0029] By adopting the above technical solution, a removable denture with high processing efficiency, good product quality and high user adaptability can be obtained.
