[0021] 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.

[0022] The traditional production process of wire loop type space maintainers is that the clinician first selects a suitable band ring or full crown on the abutment tooth, then uses elastic impression material to make an intraoral impression, casts a plaster model, and the technician uses stainless steel wire to bend the wire ring or connector on the model, which is welded to the band ring or full crown to make various types of space maintainers. This process repeatedly bends the stainless steel wire and requires spot welding and other processes. The band ring and the wire ring are connected into a whole by welding, which is time-consuming and there is a risk of gum damage, loosening and fracture. The following describes a 3D printed integrated space maintainer provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0023] Embodiment 1:

The adjustment mechanism 3 is changed synchronously to adjust and adapt the instrument, which is convenient for subsequent grinding and polishing, and further improves the comfort of the child when using it.

[0025] In order to reduce manual operation errors, effectively improve the precision and adaptability of the retainer, and protect the abutment teeth and periodontal tissues, a manufacturing mechanism 2 is proposed, wherein a computer 201, a 3D printer 202, and an oral scanner 204 are installed on the top of a workbench 1, a fixing seat 203 for fixing the oral scanner 204 is fixedly connected to the top of the workbench 1, and data between the computer 201, the 3D printer 202, and the oral scanner 204 are interconnected, and an adjustment mechanism 3 includes an oral tooth model 301 adapted to the oral cavity of the child manufactured by the oral scanner 204 and the 3D printer 202, and an integrated space maintainer assembly 302 manufactured by the computer 201, the 3D printer 202, and the oral scanner 204 is installed on the oral tooth model 301. , a digital model of the partially missing teeth in the upper and lower jaws of the child is obtained through an oral scanner 204, the occlusal relationship is obtained, the digital impression is uploaded to the digital processing center, the data value is determined through a computer 201, the designed child tooth model data and digital space maintainer data are imported into the 3D printing system, and the oral tooth model 301 and the integrated space maintainer assembly 302 are printed and produced respectively through a 3D printer 202. The intraoral data is obtained through the oral scanner 204, which can reduce the mold taking operation and reduce the discomfort of the child. The computer 201-assisted design and 3D printing technology can reduce manual operation errors, effectively improve the precision and adaptability of the retainer, protect the abutment teeth and periodontal tissues, and at the same time, the integrated printing and forming can avoid the risk of fracture, and the operation process is more time-saving and labor-saving.

[0026] Embodiment 2:

[0027] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problems in the manual design and production process in the prior art, such as the displacement of the band during transfer, resulting in inaccurate models, and low precision and low fit with teeth after production. Medical staff need to repeatedly bend and perform spot welding and other processes to connect the band and the wire ring 3023 into a whole by welding. This operation process is relatively time-consuming and labor-intensive. However, after the integrated space maintainer assembly 302 is produced, there will be stepped layer patterns on its surface. In order to improve the comfort of the child, it needs to be tested for trial wearing and its outer surface needs to be treated accordingly.

[0028] In order to further adapt and process the manufactured integrated spacer assembly 302, Figure 1 and Figure 3 as well as Figure 4As shown, an integrated space maintainer assembly 302 is proposed, wherein a fixed sleeve 3021 is provided, and two anteroposterior supports 3022 are fixedly connected to the top of the fixed sleeve 3021, a wire loop 3023 is fixedly connected to one side of the fixed sleeve 3021, and a lateral support 3024 is fixedly connected to one side of the wire loop 3023, the wire loop 3023 is parallel to the alveolar ridge of the edentulous area, and the distance from the gum is 1 mm, so that the wire loop 3023 does not affect the growth and eruption of new teeth, and the fixed sleeve 3021 is engaged with the independent tooth closest to the edentulous area, so that the two anteroposterior supports 3022 are engaged with the pits and grooves thereof, and the contact position of the lateral support 3024 with the non-independent tooth closest to the edentulous area is located at the most protruding point of the distal surface of the tooth or slightly below this point. The integrated space maintainer assembly 302 is square, and is in surface contact with the distal adjacent surface of the tooth in a concave-convex manner rather than point contact, so that the integrated space maintainer assembly 302 can be stably fixed in the toothless space area of ​​the child. The inner side of the fixed shell 3021 and one side of the lateral support 3024 are both roughened to form a rough surface 3025. The setting of the two rough surfaces 3025 further improves the connection effect between the integrated space maintainer assembly 302 and the teeth. At the same time, the integrated space maintainer assembly 302 can be fixed and tried through the oral tooth model 301, which is convenient for the staff to grind and polish the surface of the integrated space maintainer, thereby reducing the roughness of the outer surface, making the child more comfortable when using it, and further protecting the child's abutment teeth and periodontal tissues.
