[0003] In conventional designs, the front teeth and metal brackets are directly bonded together with adhesives. Although this can form a simple fixation, the area that can be in contact with the adhesive is very limited due to the uneven shape of the resin teeth. The adhesive is easy to detach during use, and the front teeth are easy to fall off during use. Therefore, a crystal mechanism for connecting the metal maxillofacial region and the resin teeth is proposed to solve the above problem. Utility Model Content

[0028] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a crystal mechanism for connecting a metal jaw face with a resin tooth, comprising a metal jaw face 1 for supporting the overall device, a positioning groove 14 for accommodating a resin tooth 3 is arranged at the left end of the metal jaw face 1, and a resin tooth 3 for decorative purposes is inserted at the top of the positioning groove 14, and a supporting block 15 for fixing the resin tooth 3 is arranged at the left end of the metal jaw face 1 near the right end of the positioning groove 14. In the traditional process, an adhesive is generally applied directly between the supporting block 15 and the resin tooth 3. Since the gap there is large, more adhesive liquid is required, and since the right end surface of the resin tooth 3 is uneven, the contact area with the adhesive is limited, and the fixing effect is poor during fixation, and it is easy to fall off. The left end of the supporting block 15 is provided with a connecting component 2 for fixing the resin tooth 3.

[0030] Reference Figure 3 - Figure 5 The connecting component 2 includes a support rod 21 for supporting the entire connecting component 2. The right end of the support rod 21 is fixedly connected to the left end of the support block 15. The support rod 21 includes a connecting layer 211 for supporting the spiral block 22. The connecting layer 211 uses a photosensitive resin as a printing material, has a high rebound rate and a low water absorption rate, and the outer wall of the connecting layer 211 is fixedly connected to the spiral block 22 for increasing the adhesion area. The inner wall of the connecting layer 211 is fixedly connected to the supporting layer 212 for supporting. Layer 212 is made of nylon material and can provide a good supporting effect. The right end of the resin tooth 3 is provided with a vertical groove 31 for accommodating the support rod 21. The support rod 21 is inserted into the inner wall of the vertical groove 31. The inner wall of the vertical groove 31 is provided with a fastening groove 32 for accommodating the spiral block 22. The cross-section of the spiral block 22 is set to be semicircular. The fastening groove 32 and the spiral block 22 are adapted to each other. The contact area between the spiral block 22 and the inner wall of the fastening groove 32 is large. After filling with adhesive, there can be a large adhesion area, and the fixing effect is better.

[0031] Reference Figure 1 - Figure 3 The front end of the metal maxillofacial mask 1 is provided with a supporting surface 11 for supporting the metal maxillofacial mask 1. When the metal maxillofacial mask 1 is installed in the patient's mouth, the supporting surface 11 can support the toothless part inside the patient's mouth. The right end of the supporting surface 11 is fixedly connected with a fixing groove 12 for fixing the entire metal maxillofacial mask 1. The fixing groove 12 can be connected to the patient's molars. The rear end of the metal maxillofacial mask 1 is provided with a receiving groove 13 for accommodating the patient's teeth. There are multiple groups of fixing grooves 12, and another group of fixing grooves 12 is arranged at the right end of the accommodating groove 13.

[0032] Working principle: When manufacturing the metal maxillofacial device 1, the patient's maxillofacial mask needs to be made first, and then a fixed position can be selected in the scanning software. After that, multiple groups of connection components 2 can be generated according to the same direction parameters, and multiple groups of data can be combined with the original data. Finally, the SLM printing technology is used to print and form the whole body.

[0033] After the metal maxillofacial portion 1 is manufactured, the resin tooth 3 can be inserted into the positioning groove 14, and the resin tooth 3 can be pushed to move toward the connecting component 2 until the support rod 21 and the spiral block 22 are inserted into the resin tooth 3, and then the adhesive can be filled into the resin tooth 3, so that the resin tooth 3 can be fixed to the top of the metal maxillofacial portion 1.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
