Description

Technical Field

[0001] This application relates to the field of all-ceramic crown processing technology, and specifically discloses a reinforcement device for processing zirconia porcelain crowns. Background Technology

[0002] Zirconia porcelain crowns, also known as all-ceramic crowns, are restorative crowns used to restore damaged teeth and meet functional and aesthetic requirements. They are a type of denture and are widely used in the fields of dental restoration and cosmetic dentistry due to their wear resistance, resistance to deformation, stable color, and translucency.

[0003] Before being used, all-ceramic crowns undergo multiple processing steps, starting with a dental plaster mold. This involves scanning, mold making, carving the blank, immersion in liquid ceramic, pressure curing, inspection, and packaging. Finally, in the laboratory, the crown is polished and glazed to create a lifelike ceramic crown. After the mold is made, the blank needs to be meticulously carved. During the carving process, a reinforcing device is used to fix the mold in place.

[0004] However, existing reinforcement devices for all-ceramic crown molds can only fix the bottom of the mold and cannot be adjusted according to changes in the mold's specifications and shape. This results in poor mold stability, causing the mold to easily shift under processing stress, leading to shape errors in the finished mold and affecting the production quality of all-ceramic crowns. Therefore, the inventors have provided a reinforcement device for processing zirconia porcelain crowns to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the reinforcement device used in traditional all-ceramic dental molds cannot be adjusted according to changes in the mold's specifications and shape, resulting in displacement changes in the mold during processing and causing shape errors.

[0006] To achieve the above objectives, the basic solution of this utility model provides a reinforcement device for processing zirconia porcelain crowns, including a fixed base for placing an all-ceramic crown mold and several reinforcement components disposed on the fixed base for fixing the all-ceramic crown mold. The fixed base has vertical mounting plates symmetrically arranged on its sides. The reinforcement components include several electric telescopic rods uniformly and vertically disposed on the vertical mounting plates, reinforcement blocks installed at the ends of each electric telescopic rod, connecting pads connecting adjacent reinforcement blocks for protecting the periphery of the all-ceramic crown mold, and a controller. The reinforcement blocks have a cylindrical structure, and each reinforcement block is provided with a pressure sensor on the side near the all-ceramic crown mold. The electric telescopic rods and pressure sensors are electrically connected to the controller.

[0007] The principle and effect of this basic scheme are as follows:

[0008] 1. Compared with existing technologies, this utility model, through the setting of a fixed base and multiple sets of reinforcing components on the fixed base, facilitates the support, placement, and tightening of the all-ceramic dental mold. The use of an electric telescopic rod to drive the telescopic movement of the reinforcing blocks facilitates the reinforcement of the sides of the all-ceramic dental mold located on the fixed base. The cylindrical structure of the reinforcing blocks allows for adjustment of the reinforcement points and range according to the specific contour shape of the all-ceramic dental mold. The tangential contact of the cylindrical surfaces facilitates contact with the all-ceramic dental mold and allows for fine-tuning to adapt to the mold's shape and structure, making fine-tuning more precise. Convenient and well-fitting, this design improves the stability of the all-ceramic dental mold during carving, thus ensuring the processing quality. By incorporating a pressure sensor to detect the contact pressure between the reinforcing block and the all-ceramic dental mold, the reinforcement force can be controlled. This not only ensures the stability of the all-ceramic dental mold but also prevents excessive stress that could damage its structure. This solves the problem that traditional all-ceramic dental reinforcement devices can only clamp and fix the bottom of the tooth, which can easily cause displacement and deviation during processing.

[0009] Furthermore, the connecting pad is an elastic structure. By making the connecting pad an elastic structure, it is easy to adjust its circumference as the electric telescopic rod extends and retracts.

[0010] Furthermore, each of the reinforcing components includes three electrically operated telescopic rods. The connecting pads installed between the reinforcing blocks on adjacent electric telescopic rods can be rolled up. One end of each connecting pad is fixed to both sides of the middle reinforcing block, and the other end is wound around the outer reinforcing block. The rollable connecting pads between the reinforcing blocks on the electric telescopic rods facilitate adjustment of the length of the connecting pads, allowing them to apply lateral pressure and provide containment for the all-ceramic crown.

[0011] Furthermore, the reinforcing block at one end of the reinforcement member has a receiving groove on its inner side, and an automatic winding mechanism for winding up the connecting pad is provided in the receiving groove. By setting the receiving groove and installing the automatic winding mechanism, it is convenient to automatically wind up the connecting pad as the electric telescopic rod and the reinforcing block change position.

[0012] Furthermore, several electrically operated lifting rods are provided between the bottom of the vertical mounting plate and the fixed base, and these rods are electrically connected to the controller. By providing these electric lifting rods, the height of the vertical mounting plate can be easily adjusted, thereby enabling height adjustment of the overall reinforcement structure. This allows the height of the electric telescopic rods and the reinforcement block to be adapted to the height of the all-ceramic dental mold. Attached Figure Description

Obviously, the accompanying drawings described below are only some embodiments of this application.

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

Reinforcing block; 6. Connecting pad; 7. Pressure sensor; 8. Receiving groove; 9. Electric lifting rod.

[0017] A reinforcing device for processing zirconia porcelain crowns, implementing, for example... Figure 1 As shown: It includes a fixing base 2 for placing the all-ceramic dental mold 1 and four sets of reinforcing components on the fixing base 2 for fixing the all-ceramic dental mold 1. The sides of the fixing base 2 are symmetrically provided with vertical mounting plates 3. The reinforcing components include multiple electric telescopic rods 4 evenly and vertically arranged on the vertical mounting plates 3, reinforcing blocks 5 installed at the ends of each electric telescopic rod 4, connecting pads 6 connecting adjacent reinforcing blocks 5 for surrounding the periphery of the all-ceramic dental mold 1, and a controller. The reinforcing blocks 5 are cylindrical structures. Each reinforcing block 5 is provided with a pressure sensor 7 on the side near the all-ceramic dental mold 1. The electric telescopic rods 4 and the pressure sensors 7 are electrically connected to the controller, which may include, but is not limited to, a PLC controller.

[0018] Among them, such as Figure 1 As shown, the connecting pad 6 is an elastic structure.

[0019] Among them, such as Figure 1 and Figure 1 As shown, each of the reinforcement components includes three electric telescopic rods 4. The connecting pads 6 installed between the reinforcement blocks 5 on adjacent electric telescopic rods 4 can be rolled up and installed. One end of the connecting pad 6 is fixed to both sides of the middle reinforcement block 5, and the other end of the connecting pad 6 is wrapped around the outer reinforcement block 5.

[0020] Among them, such as Figure 1As shown, the inner side of the reinforcing block 5 located at the end of the reinforcement is provided with a receiving groove 8. The receiving groove 8 is provided with an automatic winding mechanism for winding up the connecting soft pad 6. The automatic winding mechanism adopts the same structure as the automatic recycling structure of the existing automatic tape measure.

[0021] Among them, such as Figure 1 As shown, each vertical mounting plate 3 has four electric lifting rods 9 between its bottom and the fixed base 2, and the electric lifting rods 9 are electrically connected to the controller.

[0022] In the specific implementation of this utility model, when it is necessary to carve the all-ceramic dental mold 1, the controller controls the electric telescopic rod 4 to drive the reinforcing block 5 to retract to the initial position. Then, the height of the reinforcing block 5 is determined according to the height of the all-ceramic dental mold 1 to be carved. The controller controls the electric lifting rod 9 to drive each vertical mounting plate 3 to lift and adjust, thereby completing the height adjustment of the reinforcing block 5 and making it suitable for use with the height of the all-ceramic dental mold 1. Next, the all-ceramic dental mold 1 is placed on the fixed base 2, and the electric telescopic rods 4 are extended by the controller, so that each reinforcing block 5 is tangentially pressed against the periphery of the all-ceramic dental mold 1. When the value on the pressure sensor 7 tends to stabilize, the surface reinforcing blocks 5 have completed the tightening and fixing of the all-ceramic dental mold 1, and the electric telescopic rods 4 stop extending. During this process, as the electric telescopic rods 4 extend and each reinforcing block 5 finally stops moving, the connecting soft pad 6 performs unwinding and extension and tightly surrounds the outer periphery of the all-ceramic dental mold 1, thus completing the reinforcement operation of the all-ceramic dental mold 1. Then, the carving and processing of the all-ceramic dental mold 1 can begin.

[0023] Compared with the prior art, this utility model, by setting a fixing base 2 and multiple sets of reinforcing components on the fixing base 2, facilitates the support, placement, and tightening of the all-ceramic dental mold 1. The electric telescopic rod 4 drives the telescopic movement of the reinforcing block 5, facilitating the reinforcement operation on the side of the all-ceramic dental mold 1 located on the fixing base 2. The cylindrical structure of the reinforcing block 5 allows for adjustment of the reinforcement points and range according to the specific contour shape of the all-ceramic dental mold 1. The tangential contact of the cylindrical surfaces facilitates contact with the all-ceramic dental mold 1 and allows for fine-tuning operations to adapt to the shape and structure of the all-ceramic dental mold 1. It is more convenient and fits better, thus making the all-ceramic dental mold 1 more stable during carving and processing, thereby ensuring the processing quality of the all-ceramic dental mold 1. By setting pressure sensor 7, the contact pressure between the reinforcing block 5 and the all-ceramic dental mold 1 is detected, thereby controlling the reinforcing force on the all-ceramic dental mold 1. This not only ensures the stability of the all-ceramic dental mold 1, but also avoids excessive force on the all-ceramic dental mold 1, which could lead to structural damage. This solves the problem that traditional reinforcing devices used in all-ceramic dental processing can only clamp and fix the bottom of the all-ceramic dental mold, which can easily cause displacement and deformation of the all-ceramic dental mold during processing, resulting in processing deviations.
