Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a protective device for the molded product during the trial fitting of complete dentures. Background Technology

[0002] With the accelerating aging of China's population, the demand for custom-made removable dentures (especially complete dentures) is showing a significant upward trend. In the process of making custom-made dentures, in order to ensure the smooth wearing of the final dentures, a trial tooth alignment operation is required before the formal denture making. The core purpose of this operation is to accurately determine the patient's occlusal relationship, and the dentist will perform a trial fitting for the patient to verify the results.

[0003] Currently, when transporting completed trial-arranged dentures, dental prosthesis manufacturers first install them using an articulator. Existing articulators, such as... Figure 1 As shown, the prosthesis mainly consists of four core parts: the maxillary body, mandibular body, condylar movement system, and supporting structure. After the prosthesis is installed, it is generally transported in a paper box. However, this packaging method has many drawbacks: Firstly, the internal space of the paper box is relatively large. When the transport vehicle travels on bumpy roads, the frame and prosthesis will bounce up and down inside the box, causing them to collide with the upper and lower parts of the box, which can easily damage the prosthesis and seriously affect its protection, storage, and transportation effectiveness. Secondly, the existing packaging method cannot effectively ensure that the occlusal relationship of the trial-fit prosthesis remains stable during transportation and storage. There may be a problem where the occlusal relationship is good during the trial-fit, but the final prosthesis worn clinically differs significantly from the trial-fit, resulting in the need to remake the prosthesis. This increases the production cost for the company and prolongs the waiting time for patients. Therefore, we propose a protective device for the finished product during the trial-fit of complete dentures to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a protective device for the molded product during the fitting of complete dentures. When in use, no complicated fixing tools are required. Assembly can be completed simply by embedding the frame into the corresponding contour structure and covering it with a protective pad. Furthermore, the contour groove and contour slot are perfectly matched with the upper and lower structures of the frame. This can effectively prevent the frame from jumping up and down and shaking during transportation, thus improving the stability after installation.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A protective device for the molded denture during the trial fitting process, including...

[0007] The box body has a first protective pad fixedly installed on the bottom side inside the box body, and the upper side of the first protective pad has a contoured groove that matches the bottom structure of the jaw frame.

[0008] The contoured groove includes a base receiving area for accommodating the support base at the bottom of the jaw frame, a connection end receiving groove adapted to the connection end at the bottom of the jaw frame, and two arc-shaped grooves that match the two ear plates at the bottom of the jaw frame.

[0009] The second protective pad is placed inside the housing. The bottom of the second protective pad has a contoured slot that matches the top structure of the jaw frame. The contoured slot includes a maxillary body receiving slot for accommodating the upper base of the jaw frame, a condylar guide avoidance area that matches the upper condylar guide assembly of the jaw frame, two assembly slots that match the positions of the two ear plates of the jaw frame, and a knob receiving cavity for limiting the adjustment knob of the jaw frame.

[0010] As a preferred technical solution, both the first protective pad and the second protective pad are made of elastic cushioning material, which is EVA foam, silicone or polyurethane foam.

[0013] As a preferred technical solution, the inner walls of the contoured groove and the contoured card slot are provided with several elastic protrusions, the height of which is 1mm to 3mm.

[0014] The beneficial effects of this utility model are:

[0015] 1. Precise and stable positioning: The contoured grooves and slots are perfectly matched with the upper and lower structures of the jaw frame. Combined with 1-3mm elastic protrusions on the inner wall, they fill the tiny gaps to form multi-point compression, preventing the jaw frame and molded products from shifting or shaking during storage and transportation.

[0016] 2. Comprehensive protection: The first and second protective pads are made of elastic cushioning materials such as EVA foam, which can absorb impact and reduce hard contact. Combined with the raised dots to disperse the impact force, they can effectively prevent scratches, damage to molded products and damage to jaw components.

[0017] 3. Convenient and efficient operation: No complicated fixing tools are required. Assembly can be completed simply by embedding the jaw frame into the contour structure and covering it with the protective pad. The through groove of the second protective pad makes it easy to remove. The straps and Velcro on the case can be quickly reinforced, simplifying the protection operation before and after trying on the case. It can also be reused, making it highly practical.
