Description

Technical Field

[0001] This utility model relates to the field of dental glass-ceramic technology, and more specifically, to a support device for the manufacture of dental glass-ceramics. Background Technology

[0002] Glass-ceramics are polycrystalline solids produced by controlled crystallization of glass, resulting in a uniform distribution of crystalline and glassy phases. The crystalline phase increases the strength and improves the mechanical properties of the glass. The presence of the glassy phase helps maintain good optical properties and enhances aesthetics. Glass-ceramics are gradually becoming the preferred material for aesthetic dental restorations.

[0003] In the production process of dental glass ceramics, heat treatment processes such as annealing, nucleation, and crystallization are required, and temperature control is necessary during these processes, such as accelerating cooling to improve production efficiency.

[0004] Dental glass ceramics can also be chemically strengthened through high-temperature salt bath ion exchange, forming a layer of compressive stress on the surface of the denture, thereby improving the wear resistance, hardness, and bending strength of glass ceramic dentures.

[0005] However, most glass-ceramic denture support plates and strengthening devices are currently inconvenient to access, making it difficult to heat treat and strengthen the glass-ceramic material. Furthermore, the inconvenience of handling them affects the continuous operation of heat treatment and chemical strengthening, resulting in low efficiency. Utility Model Content

[0040] The working principle of the support device for dental glass-ceramic fabrication provided in this embodiment is as follows: The support device for dental glass-ceramic fabrication provided in this embodiment is suitable for heat treatment and chemical strengthening of dental glass-ceramics. After the lithium disilicate base glass is heat-treated to become an easily machinable glass-ceramic with a lithium metasilicate crystal form, it is processed into a denture shape by CAD / CAM or CNC. When heat treatment is required on the glass-ceramic denture sample, the support plate 20 is placed upright on the base 10, that is, the socket rod 22 of the support plate 20 is inserted into the slot 11 of the base 10, so that the support plate 20 is stably fixed on the base 10. The glass-ceramic denture sample is placed into the first cavity 201 of the support plate 20 that has been inserted and fixed on the base 10, and fixed through the support hole 211. Then, the support plate 20 containing the glass-ceramic denture sample, together with the base 10, is placed in the heat treatment furnace for heat treatment. The setting of the first ventilation groove 213 and ventilation hole 212 helps to ensure that the glass-ceramic denture sample is heated evenly, and the temperature is maintained at the same as the strengthening temperature after the treatment.

[0041] The prepared salt bath is placed into the second cavity 301 of the strengthening tank 30 and melted at the strengthening temperature for 2-5 hours to ensure that the salt bath is mixed evenly and in sufficient quantity. The glass-ceramic denture with the crystallized material is taken out from the heat treatment furnace. The carrier plate 20 is removed from the base 10 using a clamp and inverted into the salt bath of the heated strengthening tank 30. The strengthening tank 30 with the carrier plate 20 inverted is placed in the heating furnace for ion exchange chemical strengthening treatment to obtain the finished glass-ceramic denture.

[0042] The beneficial effects of the support device for dental glass-ceramic fabrication provided in this embodiment are as follows:

[0043] (1) The support plate 20 is inserted and fixed on the base 10 and placed in the heat treatment furnace for heat treatment. The cooperation between the support plate 20 and the base 10 improves the convenience and stability of taking and placing denture samples. The support plate 20 is provided with a first ventilation groove 213 and ventilation hole 212. When the denture sample is placed, the ventilation effect is improved, which facilitates uniform heat treatment of the denture sample, ensures product consistency, and improves production efficiency.

[0044] (2) The treatment plate is placed upside down on the strengthening groove 30 and placed in a heating furnace for chemical strengthening treatment. The support plate 20 is placed upside down in the strengthening groove 30 to cooperate with it. The first ventilation groove 213 of the support plate 20 and the second ventilation groove 31 of the strengthening groove 30 form convective air. The ventilation hole 212 on the support plate 20 cooperates with the first ventilation groove 213 and the second ventilation groove 31 to ensure the stability of the strengthening effect of the denture finished product.

[0045] (3) After the heat treatment is completed, take out the support plate 20 and place it upside down on the strengthening tank 30. Chemical strengthening treatment can be carried out immediately, saving time and improving production efficiency.

[0046] In one embodiment, see Figure 3 The diameter of the bearing hole 211 on the side closer to the upper surface of the bearing plate body 21 is larger than the diameter on the side farther from the lower surface of the bearing plate body 21, and the bearing hole 211 is frustum-shaped. That is, the upper diameter of the bearing hole 211 is small and the lower diameter is large, forming a frustum shape from top to bottom. By setting the bearing hole 211 to a frustum shape, the support of the denture sample can be inserted into the frustum-shaped bearing hole 211, so as to stably place the denture sample on the bearing plate 20.

[0047] In one embodiment, see Figure 3 The bearing hole 211 is connected to the first ventilation groove 213. Setting the first ventilation groove 213 and the bearing hole 211 to be connected facilitates the placement and removal of the denture sample, and also allows the denture sample to be placed stably on the bearing plate 20.

[0048] In one embodiment, see Figure 3 The support plate body 21 has multiple first ventilation slots 213 on its sidewalls, arranged in a circumferential array. The bottom of the support plate body 21 has multiple support holes 211, also arranged in a circumferential array. The multiple first ventilation slots 213 and support holes 211 are interconnected. The multiple first ventilation slots 213 further improve ventilation, facilitating uniform heat treatment of the denture samples, ensuring product consistency, and improving production efficiency. The multiple support holes 211 facilitate the placement of multiple denture samples, improving the efficiency of heat treatment and chemical strengthening.

[0049] In one embodiment, the sidewall of the support plate body 21 is provided with eight first ventilation slots 213, and the eight first ventilation slots 213 are arranged in a circumferential array. The bottom of the support plate body 21 is provided with eight support holes 211, and the eight support holes 211 are arranged in a circumferential array. It should be understood that the number and arrangement of the first ventilation slots 213 and support holes 211 are not limited to the above-described situation, and other situations are also possible, which are not limited here.

[0050] In one embodiment, see Figure 3 The bottom of the support plate body 21 is provided with a plurality of ventilation holes 212, which are arranged in an array and located within a circumferential array area enclosed by the plurality of support holes 211.

[0051] In one embodiment, see Figure 4 The second ventilation groove 31 is disposed on the side wall edge of the reinforcing groove 30, and the second ventilation groove 31 is correspondingly disposed with the first ventilation groove 213. When the support plate 20 is placed upside down on the reinforcing groove 30, the second ventilation groove 31 and the first ventilation groove 213 are correspondingly disposed to form convective air, which improves the stability of the reinforcement effect of the finished denture.

[0052] In one embodiment, see Figure 4 The sidewall edge of the reinforcing groove 30 is provided with a plurality of second ventilation grooves 31, and the plurality of second ventilation grooves 31 are distributed in a circumferential array.

[0053] In one embodiment, the sidewall edge of the support plate body 21 is provided with four ventilation holes 212, which are arranged in an array.

[0054] In one embodiment, see Figure 5 The inner diameter of the support plate 20 is larger than the outer diameter of the reinforcing groove 30, which facilitates placing the support plate 20 containing the denture sample into the reinforcing groove 30. That is, when the support plate 20 is placed upside down on the reinforcing groove 30, the inner wall of the support plate 20 is located outside the outer wall of the reinforcing groove 30. It should be understood that, to ensure the chemical strengthening effect, the circumferential array area formed by the multiple support holes 211 must be smaller than the inner diameter of the reinforcing groove 30.

[0055] In one embodiment, the base 10 is provided with a plurality of horizontal slots 11.

[0056] In one embodiment, the base 10 is provided with multiple vertical slots 11.

[0057] In one embodiment, see Figure 1 The base 10 is provided with multiple horizontal slots 11 and multiple vertical slots 11, and the horizontal slots 11 and vertical slots 11 intersect each other. Optionally, the horizontal slots 11 and vertical slots 11 intersect perpendicularly.
