Description

Technical Field

[0001] The invention relates to the technical field of artificial teeth processing, in particular to a method for making implanted artificial gums. Background Art

[0002] Oral restoration mainly includes three methods: fixed restoration, removable restoration and implant restoration. Implant restoration has developed rapidly since the theory of osseointegration was proposed, and has become very mature after decades of clinical trials and practices. In addition, the inclusion of implant restoration-related consumables in centralized procurement has made its price more affordable, and implant restoration has become the preferred restoration method for many dentists and gingival patients. In the design of implant restoration, the false gums correspond to the gingival soft tissue in the mouth, which is very critical to the gingival morphology, gingival depth and aesthetics of the denture.

[0003] The main method of making false gums in the existing traditional technology is: a hospital takes a mold and pours a plaster model, obtains an impression by wrapping silicone rubber on the implantation area of ​​the plaster model, and then uses tools to dig or grind off the plaster to obtain the false gum cavity that needs to be formed. The impression is further placed in the corresponding position of the "ground plaster model" and an overflow hole is punched on the side. The gum gun injects silicone rubber into the false gum cavity through the hole left on the impression to fill the cavity. After waiting for a period of time, the silicone rubber solidifies and the false gum is completed. The other is to establish a digital model to obtain three models: a working model, a gum model, and an opposing jaw model. The above-mentioned gum model and the working model are spliced ​​together to take a mold to obtain an impression of the entire model, and then the impression is pressed on the working model. A hole is opened on the side of the impression to inject silicone rubber, and the silicone rubber is waited for to solidify. The false gum is completed.

[0004] However, the above method has the following defects when making false gums: 1. The steps of making false gums are very complicated and time-consuming. 2. Silicone rubber materials are expensive and there is a lot of waste in the molding process, so the cost is high. 3. The traditional method is to form a filling cavity with a silicone rubber impression and a working model. Due to its material properties, the silicone rubber impression is elastic and unstable. When filling, the material will squeeze around it and deform and shift. The final false gum does not fit the working model completely, and the fit is poor. It may be partially higher or there may be gaps, which affects the accuracy of false gum production and the quality of later denture implants. Therefore, there is room for major improvements. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a method for making implanted false gums, which simplifies the steps of making false gums, reduces the cost of making false gums, improves the accuracy of making false gums, and ensures the quality of later false tooth implantation.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] The present invention discloses a method for making implanted artificial gums, comprising the following steps:

[0008] S1. Scan the patient's oral cavity to obtain working model data, scanning rod data and jaw model data;

[0009] S2, establishing a matched working model, a gum model and an opposing jaw model according to the acquired working model data, the scanning rod data and the opposing jaw model data;

[0010] S3, importing the gum model into three-dimensional software to make a gum box model;

[0011] S4, printing the gum box model using a 3D printing device;

[0012] S5, filling the printed gum box model with glue;

[0013] S6. The production of implanted dentures is completed.

[0014] Furthermore, in step S1, a 3D scanning device or an oral scanner is used to scan the patient's oral cavity to obtain the working model data, the scanning rod data and the opposing jaw model data.

[0015] Furthermore, the working model data, the scanning rod data and the opposing jaw model data acquired in S1 are imported into modeling software to establish a coordinated working model, gum model and opposing jaw model; the modeling software is, for example, 3Shape software or EXOCAD software.

[0016] Furthermore, the gum model is imported into Magics software to make a gum box model.

[0017] Furthermore, the use of Magics software to make a gum box model includes the following steps. For the gum model processing generated by the gum model, first select the hollow part tool, further select the shell function, select the shell wall thickness, select the shell detailed specifications, the type faces outward, further select the multiple sections of the view tool page, further change the Z-axis position to 0, further select the section cutting option of the cutting or punching tool, further select cutting the visible section and apply to complete the box production.

[0018] Furthermore, the shell wall thickness of the gum model in the shell extraction function is T, 1mm≤T≤2mm.

[0019] Furthermore, the detailed specification of the gum model in the shell extraction function is L, 0.3mm≤L≤0.6mm.

[0020] Further, the produced gum box model is selected for saving.

[0021] Furthermore, in step S4, the gum box model is opened upward during printing.

[0022] Furthermore, in step S5, during the process of filling the printed gum box model with glue, the prepared glue is injected into the gum box model, the gum box model is filled with glue, and the glue is flattened with an extrusion plate so that the glue surface formed by the glue is flush with the outer edge of the gum box model.

[0023] Furthermore, the extrusion plate is a glass plate, and the glass plate is used to extrude the glue so that the glue completely fills the entire gum box model and squeezes out excess glue.

[0024] The beneficial effects of the present invention are as follows: the implanted false gum manufacturing method of the present application is used for implanted false gum manufacturing, and by setting a gum box model, the process of silicone rubber mold taking is eliminated. On the one hand, the false gum manufacturing steps are simplified, and the traditional false gum manufacturing method needs to wait for silicone rubber to cure. The gum box model is short in production time, making the false gum manufacturing more time-saving; on the other hand, the silicone rubber mold taking process is eliminated, and a large amount of silicone rubber mold making is not required, which greatly reduces the waste of silicone rubber materials, thereby reducing the cost of false gum manufacturing; the setting of the gum box model makes the outer wall of the implanted false gum and the outer wall of the implanted false gum close to each other. The inner walls of the gum box model are completely fitted together, the outer wall of the gum model obtained in step S2 is completely fitted with the side wall of the working model, and the inner wall of the gum box model in step S3 is completely fitted with the outer wall of the gum model, thereby ensuring that the side wall of the implanted false gum is completely and tightly fitted with the side wall of the working model, avoiding the situation in which the false gum made after the traditional method of splicing the impression and the working model to form a cavity and completing the filling of glue is not tightly fitted with the working model or even has a gap, resulting in incorrect gingival penetration shape and depth of the subsequent denture, thereby improving the accuracy of false gum production and ensuring the quality of later denture implants.

[0030] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0031] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a method for making implanted artificial gums of the present invention comprises the following steps:

[0033] S1. Scan the patient's oral cavity to obtain working model data, scanning rod data and jaw model data;

[0034] S2, establishing a matching working model, gum model and opposing jaw model according to the acquired working model data, the scanning rod data and the opposing jaw model data; modeling software such as 3Shape software or EXOCAD software;

[0035] S3. Importing the gum model into three-dimensional software to make a gum box model; the three-dimensional software is such as Solidworks software or Magics software.

[0036] S4, printing the gum box model using a 3D printing device;

[0037] S5, filling the printed gum box model with glue;

[0038] S6. The production of implanted dentures is completed.

[0039] The gum box model is a concave gum box model, the silicone rubber fills the gum box model, the silicone rubber plane is flush with the top surface of the gum box model, and it can be taken out after the silicone rubber dries. Before designing the denture, you can first put the false gum into the cutting position of the working model to ensure that the false gum and the cutting position of the working mold are completely fitted, and then put the opposing jaw model on the working model with the false gum to ensure that the opposing jaw model and the working model with the false gum bite normally, thereby ensuring the accuracy of subsequent denture production.

[0040] Based on the above-mentioned method for making implanted false gums, the process of taking silicone rubber molds is eliminated by setting a gum box model. On the one hand, the steps of making false gums are simplified, and the time required to wait for silicone rubber to solidify in the traditional method of making false gums is reduced. The gum box model is short in production time, making the false gum production more time-saving; on the other hand, the silicone rubber mold-taking process is eliminated, and a large amount of silicone rubber molds are not required, which greatly reduces the waste of silicone rubber materials, thereby reducing the cost of making false gums; the setting of the gum box model makes the outer wall of the implanted false gums and the gum box model The inner walls of the gingival model are completely fitted together, the outer wall of the gingival model obtained in step S2 is completely fitted with the side wall of the working model, and the inner wall of the gingival box model in step S3 is completely fitted with the outer wall of the gingival model, thereby ensuring that the side wall of the implanted false gingiva is completely and tightly fitted with the side wall of the working model, avoiding the phenomenon that the false gingiva made after the traditional method of splicing the impression and the working model to form a cavity and completing the filling of glue is not tightly fitted with the working model or even has a gap, resulting in incorrect gingival penetration shape and depth of the subsequent denture, thereby improving the accuracy of false gingiva production and ensuring the quality of later denture implantation.

[0041] Wherein, in step S1, a 3D scanning device or an oral scanner is used to scan the patient's oral cavity to obtain the working model data, the scanning rod data and the jaw model data.

[0042] For example, an oral scanner is used to scan the patient's oral cavity to obtain working model data, scanning rod data and jaw model data, and the obtained data is sent to a three-dimensional software platform for design.

[0043] As an implementable method, in step S2, the working model data, the scanning rod data and the opposing jaw model data are imported into 3Shape software to establish a matching working model, gingival model and opposing jaw model.

[0044] As an implementable method, in step S3, the gum model is imported into Magics software to produce a gum box model.

[0045] Import the gum model into Magics software, which can quickly prototype and design and produce the required gum box model.

[0046] Specifically, the use of Magics software to make a gum box model includes the following steps: for the gum model processing generated by the gum model, first select the hollow part tool, further select the shell function, select the shell wall thickness, select the shell detailed specifications, the shell type faces outward, further select the multiple sections of the view tool page, further change the Z-axis position to 0, further select the section cutting option of the cutting or punching tool, further select cutting the visible section and apply to complete the box production.

[0047] The shell wall thickness of the gingival model described in the shell extraction function is T, 1mm≤T≤2mm.

[0048] The shell wall thickness T of the gingival model can be selected according to the specific needs of the gingival model, such as 1 mm, 1.5 mm or 2 mm. For example, the wall thickness T in this application is 1.5 mm.

[0049] The detailed specification of the gingival model described in the shell extraction function is L, 0.3mm≤L≤0.6mm.

[0050] The detailed specifications of the gum model can be selected according to the specific needs of the gum model, such as 0.3mm or 0.5mm or 0.6mm. For example, the detailed specification in this application is 0.5mm.

[0051] Preferably, the produced gum box model is selected for preservation.

[0052] The prepared gum box model is saved so that if the gum box is damaged in subsequent processes, a gum box model can be printed again quickly and accurately.

[0053] As an implementation method, in step S4, the gum box model is printed with the opening facing upward. Printing with the opening facing upward improves printing efficiency and reduces post-processing, so that the gum box model can be printed with high efficiency and low cost.

[0054] As an implementable method, in step S5, during the process of filling the printed gum box model with glue, the prepared glue is injected into the gum box model, the gum box model is filled with glue, and the glue is flattened with an extrusion plate so that the glue surface formed by the glue is flush with the outer edge of the gum box model.

[0055] The gum box model is injected with glue and flattened with an extrusion plate. Compared with the traditional method of open-hole injection, the glue fills the gum box model, and the false gums are made more accurately.

[0056] Preferably, the extrusion plate is a glass plate, and the glass plate is used to extrude the glue so that the glue completely fills the entire gum box model and squeezes out excess glue.

[0057] The glass plate squeezes the glue to make the glue surface smooth, and the gum box model fits tightly with the working model, improving the accuracy of false gum production.

[0058] The above description is only a specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
