Description

Technical Field

[0001] This utility model relates to the field of dental restoration auxiliary tools, and in particular to a novel substitute hole pattern and a substitute-free 3D printing working model. Background Technology

[0002] In the process of dental implant restoration, the application of digital technology is becoming increasingly common. Specifically, the working models used in the fabrication and testing of implant restoration components are gradually shifting from traditional plaster models to primarily 3D-printed working models. During restoration, the implant is inserted into the patient's alveolar bone. When performing crown restoration, the implant cannot be used directly. In this case, a substitute is usually used and mounted on a 3D-printed working model. The abutment and other superstructure of the restoration are designed on the substitute, allowing for the fabrication of the crown.

[0003] The 3D printing working model in related technologies requires the use of a metal digital substitute (also known as a printed model substitute). Specifically, the substitute is installed onto the 3D printed working model, and the prosthesis abutment is installed on the substitute using a central screw, followed by installation. However, digital substitutes are susceptible to wear and unpredictable damage during use. If damage to the digital substitute is not detected in time, it will lead to a decrease in the accuracy of the fabricated prosthesis abutment, affecting the subsequent crown installation. Moreover, during actual installation, the digital substitute often fails to be properly installed on the printed working model, easily resulting in incorrect gingival alignment and occlusion of the prosthesis, which will also affect the subsequent crown installation. Even worse, because there are many brands and series of dental implants on the market, the wrong digital substitute is easily used during the actual production of prosthesis abutments, resulting in rework and scrap, leading to cost waste and delivery delays. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of substitute body hole pattern and substitute-free digital 3D printing model, which aims to solve the above problems.

[0005] A novel substitute hole pattern and substitute-free 3D printing working model are disclosed. The substitute-free 3D printing working model includes a model body with a cavity. The inner contour shape of the cavity matches the outer contour shape of the substitute hole pattern. The substitute hole pattern includes an interface segment, a substitute segment, and a connecting segment connected in sequence. The shape features of the substitute segment match the shape features of the substitute.

[0006] The replacement segment includes a replacement body portion and a cylindrical portion. The replacement body portion is connected to the interface segment, and the cylindrical portion is connected to the connecting segment.

[0007] Preferably, the alternative body is square, hexagonal, octagonal, or cylindrical, but is not limited to these shapes.

[0008] The outer wall of the connecting section is provided with a first thread.

[0009] Preferably, the end face diameter of the interface segment is larger than the end face diameter of the substitute segment.

[0010] Specifically, the cavity includes: a base interface, a substitute cavity, and a connecting cavity. The inner wall of the connecting cavity is provided with a first connecting part. The lower end of the prosthesis base is fitted into the substitute cavity, and a screw passes through the prosthesis base and is connected to the first connecting part.

[0011] Preferably, the first connecting part is a second thread.

[0012] This invention discloses a novel replacement body hole pattern. It replaces traditional replacement body hole patterns from 3Shape or EXO databases, which are suitable for digital replacement body installation, with a novel replacement body hole pattern suitable for abutment and screw installation. The main body of the model is designed using software, and then 3D printed to create a replacement-free 3D printed working model. The main body of the model has a cavity whose inner shape is adapted to the novel replacement body hole pattern. In application, the prosthesis abutment is installed in the cavity using screws.

[0025] A novel alternative body hole pattern and an alternative body-free 3D printing working model, such as Figure 1-4 As shown, the model includes a substitute body hole pattern 100 and a substitute-free 3D printed working model 200. The substitute-free 3D printed working model 200 includes a model body 2, which has a cavity 21. The inner contour shape of the cavity 21 is adapted to the outer contour shape of the substitute body hole pattern 100. The cavity 21 is designed and 3D printed by the substitute body hole pattern 100 through software. The substitute body hole pattern 100 includes an interface segment 11, a substitute body segment 12, and a connecting segment 13 connected in sequence. The shape features of the substitute body segment 12 are adapted to the shape features of the substitute body. The substitute body hole pattern 100 is used to form the cavity 21. Specifically, the interface segment 11 is used to form the base interface 211, the substitute body segment 12 is used to form the substitute body cavity 212, and the connecting segment 13 is used to form the connecting cavity 213.

[0026] The replacement body segment 12 includes a replacement body portion 121 and a cylindrical portion 122. The replacement body portion 121 is connected to the interface segment 11, and the cylindrical portion 122 is connected to the connecting segment 13.

[0027] Specifically, the substitute body 121 can be square, hexagonal, octagonal, or cylindrical, but is not limited to these shapes. The shape of the substitute body 121 is set according to the shape characteristics of the substitute body. In this embodiment, the shape of the substitute body 121 is set to hexagonal.

[0028] Specifically, the outer wall of the connecting section 13 is provided with a first thread 133 for forming the connecting cavity 213 of the cavity 21.

[0029] The end face diameter of the interface segment 11 is larger than the end face diameter of the substitute segment 12, so that when the substitute-free 3D printing working model 200 is completed, the size of the base interface 211 is larger than the substitute cavity, which facilitates the insertion and installation of the repair base 31.

[0030] The cavity 21 includes: a base interface 211, a replacement cavity 212, and a connecting cavity 213. The inner wall of the connecting cavity 213 is provided with a first connecting portion 2131. The lower end of the prosthesis base 31 is fitted into the replacement cavity 212. Screws 32 pass through the prosthesis base 31 and are connected to the first connecting portion 2131. In this technology, the prosthesis base 31 is installed in the cavity 21 by screws 32, eliminating the traditional steps of first installing the replacement and then installing the prosthesis base 31. It also eliminates the need for a separate replacement, significantly reducing material costs and simplifying the work process.

[0031] The first connecting part 2131 is a second thread, which is adapted to the outer wall of the end of the screw 32. The second thread is used to connect the screw 32.

[0032] In a specific embodiment, the replacement hole pattern in the traditional 3Shape or EXO database, which is suitable for digital replacement body installation, is replaced with a new type of replacement hole pattern in this invention, which is suitable for the installation of the prosthesis abutment 31 and screws 32. The prosthesis abutment 31 and model body 2 are designed by software operation. The model body 2 is provided with a cavity 21, and the inner shape of the cavity 21 is adapted to the new replacement hole pattern 100. The model body 2 and the cavity 21 are designed by software based on the replacement hole pattern 100. The model body 2 is printed by 3D printing to obtain a replacement-free 3D printed working model. In application, the prosthesis abutment 31 is installed in the cavity 21 by screws 32.

[0033] This invention discloses a novel substitute hole pattern. It replaces traditional substitute hole patterns from 3Shape or EXO databases, which are suitable for digital substitute installation, with a novel substitute hole pattern suitable for abutment and screw installation. The prosthesis and model body are designed via software. The model body has a cavity whose inner shape matches the novel substitute hole pattern. The cavity is designed using software based on the substitute hole pattern. In application, the prosthesis abutment is installed in the cavity using screws. This substitute-free 3D printed working model eliminates the need for a substitute and avoids the problem of repeated substitute use, preventing a decrease in prosthesis accuracy due to substitute wear. This improves product yield and customer satisfaction, while reducing rework and maintenance costs.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent modifications or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
