Description

Technical Field

[0001] This utility model relates to the field of full crown reinforcement technology, specifically a light-curing pressure device for bonding zirconia full crowns. Background Technology

[0002] In the field of dental restoration, existing equipment for bonding zirconia crowns has significant technical shortcomings: traditional pressurization devices are mostly single pressurization structures, lacking the dual adjustment function of "preset basic pressure + supplemental pressure as needed". Either the pressure is uncontrollable, leading to excessive pressurization that damages the abutment tooth, or insufficient pressure that leaves gaps and air bubbles. Even with auxiliary pressurization components, it is difficult to link with the main pressurization system, requiring separate operation and increasing the burden. Moreover, pressurization and light curing are often separate. Manually pressurizing first and then holding the light curing lamp for irradiation can easily cause the crown to shift due to hand tremors. The light curing lamp has no precise positioning and the angle is fixed, which can easily lead to curing blind spots for complex tooth positions. At the same time, most devices are bulky and lack handheld parts and tooth positioning mechanisms adapted to the narrow space of the oral cavity, making operation cumbersome and inefficient, and failing to meet the diverse and high-precision restoration needs of clinical practice. Utility Model Content

[0003] The purpose of this invention is to solve the problems of traditional pressure bonding, such as damage to abutment teeth due to overpressure on single structures, gaps and air bubbles due to underpressure, blind spots in complex tooth positions caused by the lack of positioning and fixed angle of the light curing lamp, and cumbersome operation and low efficiency. This invention provides a light curing pressure device for bonding zirconia full crowns.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A photocuring pressure device for bonding zirconia crowns includes a load-bearing base. A mounting base is fixedly connected to the top right end of the load-bearing base. A telescopic component is provided at the top right end of the mounting base. A top frame is sleeved on the top of the telescopic component. An adjustable pressure component passes through the inner bottom end of the top frame and is located to the left of the telescopic component. An output shaft is provided at the left end of the top frame. A tube is fixedly connected to the left end of the output shaft. A photocuring mechanism is connected to the left end of the tube. A second tube is connected to the bottom end of the output shaft. An auxiliary pressure component is provided at the top left end of the load-bearing base. The bottom end of the second tube is connected to the bottom end of the auxiliary pressure component.

[0006] Furthermore, the telescopic assembly includes a sliding sleeve and a sliding rod. The bottom end of the sliding rod passes through and is slidably connected to the inner side of the top end of the sliding sleeve. The inner side of the top frame is sleeved on the outer side of the top end of the sliding rod. Pulling the sliding rod up or down causes the top frame sleeved on the outer side of the top end of the sliding rod to rise and fall synchronously until the overall height of the left end output shaft, tube body and light curing mechanism of the top frame is flush with the target tooth position.

[0007] Furthermore, the adjusting pressure assembly includes a pressure sleeve, an elastic spiral ring, and an electric spiral push rod. The bottom end of the pressure sleeve is fixedly connected to the top left end of the mounting base, and the top ends of the elastic spiral ring and the electric spiral push rod are fixedly connected to the left end of the top frame. The top frame is slightly translated by threaded transmission, while compressing or releasing the elastic spiral ring sleeved on the outside of the electric spiral push rod.

[0008] Furthermore, the light-curing mechanism includes an outer shell, a secondary pressure pusher, a hand handle, a light source assembly, and a cavity. The top end of the second tube penetrates the tail end of the outer shell. The secondary pressure pusher is located on the inner side of the rear end of the outer shell. The hand handle is fixedly connected to the bottom side of the outer shell. The end of the outer shell away from the tube is internally sleeved onto the outer end of the cavity. The light source assembly is located at the port of the cavity. Medical personnel hold the hand handle on the bottom side of the outer shell of the light-curing mechanism and move the light-curing mechanism to the target tooth position through the flexible or rigid transmission of the tube.

[0009] Furthermore, the light source assembly includes a support rod, a light guide, a support frame, an adjustment component, and a tooth limiting ring. The beginning of the support rod is connected to the end of the cavity, and the light guide is connected to the end of the support rod. The tooth limiting ring in the light source assembly is first fitted onto the outside of the target tooth or adjacent tooth, and the precise positioning of the mechanism is achieved through the fit between the limiting ring and the tooth.

[0010] Furthermore, the top of the support frame is sleeved on the outside of the support rod, the adjustment component is disposed at the bottom of the support frame, and the tooth limiting ring is fixedly connected to the axis of the adjustment component. The light source angle is adapted by adjusting the component—pushing the support frame to make it slide along the groove.

[0011] Furthermore, the adjustment component includes a rotating shaft and a sliding groove. The sliding groove is disposed on the top circumferential side wall of the rotating shaft. The bottom end of the support frame is slidably connected to the sliding groove. The support frame slides along the sliding groove, driving the support rod to rotate around the axis of the rotating shaft, thereby adjusting the illumination angle of the light guide lamp at the end of the support rod.

[0012] Furthermore, the auxiliary pressurization component includes a pump body, a tank body, and an adjustment switch. The bottom end of the pump body is located at the top end of the tank body, the adjustment switch is located at the bottom end of the tank body, and the tank body is located on the top side of the load-bearing base. If it is necessary to further increase the pressure during the bonding process, the pressurization medium in the tank body is transmitted to the space between the outer shell and the cavity through the second pipe body, the output shaft, and the pipe body by opening the adjustment switch of the auxiliary pressurization component.

[0013] Compared with the prior art, this utility model provides a light-curing pressure device for bonding zirconia full crowns, which has the following beneficial effects:

[0014] This light-curing pressurizing device for bonding zirconia crowns forms a dual pressurization system of "main pressurization + auxiliary pressurization" through the adjustment of the pressurizing component and the auxiliary pressurizing component via a dual-tube linkage output shaft. It can preset the base pressure to avoid excessive pressure and damage to the tooth, and can supplement the pressure as needed to ensure that the zirconia crown fits tightly to the abutment tooth and that the adhesive is fully expelled without air bubbles. The light-curing mechanism integrates a hand handle for medical staff to flexibly adjust the position, and the tooth limiting ring can accurately position the device to prevent displacement. The adjustment component can drive the light guide to adjust the irradiation angle to ensure that the light curing light accurately covers the bonding interface. With the help of the secondary pressurizing pusher, pressurization and light curing can be carried out simultaneously, which greatly improves bonding efficiency and curing quality. The overall structure is suitable for complex operation scenarios in dental clinics and has strong practicality. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] like Figures 1-2 As shown, a light-curing pressure device for bonding zirconia full crowns includes a load-bearing base 1. A mounting base 2 is fixedly connected to the top right end of the load-bearing base 1. A telescopic component 3 is provided at the top right end of the mounting base 2. The telescopic component 3 includes a sliding sleeve 31 and a sliding rod 32. The bottom end of the sliding rod 32 passes through and is slidably connected to the inner side of the top end of the sliding sleeve 31. The inner side of the top frame 4 is sleeved on the outer side of the top end of the sliding rod 32. Pulling the sliding rod 32 up or down causes the top frame 4 sleeved on the outer side of the top end of the sliding rod 32 to rise and fall synchronously until the overall height of the output shaft 6, tube 9 and light-curing mechanism 7 at the left end of the top frame 4 is flush with the target tooth position.

[0024] like Figure 3 As shown, a top frame 4 is sleeved on the top of the telescopic component 3, and an adjusting pressure component 5 passes through the bottom inner side of the top frame 4. The adjusting pressure component 5 includes a pressure sleeve 51, an elastic spiral ring 52, and an electric spiral push rod 53. The bottom end of the pressure sleeve 51 is fixedly connected to the top left end of the mounting base 2, and the top ends of the elastic spiral ring 52 and the electric spiral push rod 53 are fixedly connected to the left end of the top frame 4. When the electric spiral push rod 53 is rotated, the top frame 4 is slightly moved by the threaded transmission, while the elastic spiral ring 52 sleeved on the outside of the electric spiral push rod 53 is compressed or released.

[0025] like Figure 2 As shown, the adjusting pressure component 5 is located to the left of the telescopic component 3. The left end of the top frame 4 is provided with an output shaft 6. The left end of the output shaft 6 is fixedly connected to a tube 9. The left end of the tube 9 is connected to a light curing mechanism 7. The light curing mechanism 7 includes an outer shell 71, a secondary pressure pusher 72, a hand handle 73, a light source component 74, and a cavity 75. The top end of the second tube 9 passes through the tail end of the outer shell 71. The secondary pressure pusher 72 is located on the inner side of the rear end of the outer shell 71. The hand handle 73 is fixedly connected to the bottom side of the outer shell 71. The end of the outer shell 71 away from the tube 9 is internally sleeved on the outer end of the cavity 75. The light source component 74 is located at the port of the cavity 75. The tooth limiting ring 745 in the light source component 74 is first sleeved on the outer side of the target tooth or adjacent tooth. The precise positioning of the mechanism is achieved by the fit between the limiting ring and the tooth, avoiding the device from shifting during subsequent pressure or light curing.

[0026] Example 2:

[0027] like Figure 4 As shown, the light source assembly 74 includes a support rod 741, a light guide lamp 742, a support frame 743, an adjustment component 744, and a tooth limiting ring 745. The beginning of the support rod 741 is connected to the end of the cavity 75, the light guide lamp 742 is connected to the end of the support rod 741, the top of the support frame 743 is sleeved on the outside of the support rod 741, the adjustment component 744 is set at the bottom of the support frame 743, and the tooth limiting ring 745 is fixedly connected to the axis of the adjustment component 744. The light source angle is adapted by adjusting the component 744—pushing the support frame 743, causing the support frame 743 to slide along the slide groove 7442, driving the support rod 741 to rotate around the axis of the rotating shaft 7441, thereby adjusting the illumination angle of the light guide lamp 742 at the end of the support rod 741, ensuring that the light curing light emitted by the light guide lamp 742 vertically or precisely covers the area where the adhesive is located.

[0028] like Figure 5 As shown, the adjustment component 744 includes a rotating shaft 7441 and a sliding groove 7442. The sliding groove 7442 is located on the top circumferential side wall of the rotating shaft 7441. The bottom end of the support frame 743 is slidably connected to the sliding groove 7442. The light guide lamp 742 emits light-curing light through the electrical energy transmitted by the support rod 741. The light penetrates the zirconia crown and focuses on the adhesive layer.

[0029] like Figure 2 As shown, the bottom end of the output shaft 6 is connected to a second tube 9, and an auxiliary pressurizing component 8 is provided on the top left side of the load-bearing base 1. The bottom end of the second tube 9 is connected to the bottom end of the auxiliary pressurizing component 8. The auxiliary pressurizing component 8 includes a pump body 81, a tank 82, and an adjusting switch 83. The bottom end of the pump body 81 is located at the top of the tank 82, and the adjusting switch 83 is located at the bottom of the tank 82. The tank 82 is located on the top side of the load-bearing base 1. During the bonding process, it is necessary to further increase the pressurizing pressure. By opening the adjusting switch 83 of the auxiliary pressurizing component 8, the pressurizing medium in the tank 82 is transmitted to the space between the outer shell 71 and the cavity 75 through the second tube 9, the output shaft 6, and the tube 9. The auxiliary secondary pressurizing pusher enhances the pressurizing effect and avoids the displacement of the crown due to insufficient pressure from a single pressurizing component.

[0030] Working principle: such as Figures 1-5 As shown, the load-bearing base 1 provides overall stable support for the device, and the mounting base 2 at its top right end serves as the bearing foundation for the core functional components.

[0031] Height adaptation adjustment: Based on the position and height of the tooth in the clinical operation scenario, the height of the top frame 4 is adapted by adjusting the telescopic component 3 - pull the slide bar 32 up or down, and drive the top frame 4, which is sleeved on the outer side of the top of the slide bar 32, to rise and fall synchronously until the overall height of the left end output shaft 6, tube 9 and light curing mechanism 7 of the top frame 4 is flush with the target tooth position, laying the foundation for subsequent pressure and light curing alignment;

[0032] The pressure adjustment component 5 is the core pressure control unit of the device. Its pressure sleeve 51 is fixed at the bottom end of the top left side of the mounting base 2, forming a fixed fulcrum. Rotating the electric spiral push rod 53, the top frame 4 is slightly translated by the threaded transmission. At the same time, the elastic spiral ring 52 sleeved on the outside of the electric spiral push rod 53 is compressed or released. The elastic spiral ring 52 stores or releases pressure through its own elastic deformation, locking the position of the top frame 4 at the height corresponding to the preset pressure. Then, the initial pressure is transmitted to the light curing mechanism 7 through the output shaft 6 and the tube 9 to avoid damage to the tooth body or insufficient pressure leading to bonding gaps in subsequent operations.

[0033] The auxiliary pressurization component 8 at the top left end of the load-bearing base 1 is connected to the bottom end of the output shaft 6 through the second tube 9, forming a dual pressurization system of "main pressurization + auxiliary pressurization". Before the operation, the pressurization medium (such as hydraulic oil or compressed air) in the tank 82 is injected into the second tube 9 by turning on the pump 81. The pressure of the medium is controlled by adjusting the adjustment switch 83 at the bottom of the tank 82, so as to reserve pressure for the subsequent bonding process that requires additional pressurization, and ensure that the pressure can be flexibly adjusted according to clinical needs.

[0034] Operational alignment stage: Medical staff hold the hand handle 73 on the bottom side of the outer shell 71 of the light curing mechanism 7 and move the light curing mechanism 7 to the vicinity of the target tooth position through the flexible or rigid transmission of the tube body 9. The inner end of the outer shell 71 away from the tube body 9 is connected to the cavity 75. The light source component 74 at the port of the cavity 75 is the core working end, and the bonding interface between the zirconia crown and the abutment tooth is initially aligned.

[0035] Tooth body limiting and precise positioning: The tooth body limiting ring 745 in the light source assembly 74 is first fitted on the outside of the target tooth or adjacent tooth. The precise positioning of the mechanism is achieved by the fit between the limiting ring and the tooth body, avoiding the device from shifting during subsequent pressure or light curing, and ensuring that the pressure direction is consistent with the long axis of the tooth body and the light curing light is focused on the bonding surface.

[0036] Light curing angle adjustment: If there is an angle deviation at the bonding interface, the light source angle can be adapted by adjusting component 744 - push support frame 743 to slide along slide groove 7442, drive support rod 741 to rotate around axis 7441, thereby adjusting the illumination angle of light guide lamp 742 at the end of support rod 741, ensuring that the light curing light emitted by light guide lamp 742 vertically or accurately covers the area where the adhesive is located, and avoid light refraction leading to insufficient curing;

[0037] Secondary pressurization reinforcement: After positioning and angle adjustment, the secondary pressurization pusher 72 on the inner side of the rear end of the outer shell 71 is pushed forward along the inner side of the outer shell 71 to push the cavity 75. The cavity 75 drives the light source assembly 74 to move towards the zirconia crown. At this time, the outer side of the light guide lamp 742 or the tooth limiting ring 745 contacts the outer surface of the crown, applying continuous and stable secondary pressurization (the pressure can be controlled by adjusting the deformation of the elastic spiral ring 52 of the initial pressurization assembly 5) to ensure that the adhesive between the zirconia crown and the abutment tooth is fully discharged and tightly adhered.

[0038] Photocuring start-up and adhesive curing: While maintaining stability under secondary pressure, the light guide lamp 742 of the light source assembly 74 is activated. The light guide lamp 742 emits photocuring light through the electrical energy transmitted by the support rod 741. The light penetrates the zirconia crown and focuses on the adhesive layer, so that the adhesive can fully polymerize and cure under stable pressure, ensuring that the adhesive reaches the best curing strength.

[0039] If it is necessary to further increase the pressure during the bonding process, the adjustment switch 83 of the auxiliary pressure component 8 is turned on, so that the pressure medium in the tank 82 is transmitted to the outer shell 71 and the cavity 75 through the second pipe 9, the output shaft 6, and the pipe 9. The auxiliary secondary pressure pusher enhances the pressure effect and avoids the displacement of the crown due to insufficient pressure of a single pressure component.

[0040] After the adhesive has fully cured, first turn off the light guide 742, then push the secondary pressure pusher 72 in the opposite direction to release the pressure, remove the tooth limiting ring 745, and move the light curing mechanism 7 away from the tooth position by holding the handle 73; finally, adjust the electric spiral pusher 53 in the opposite direction to release the pressure of the elastic spiral ring 52, slide the slide bar 32 downward to reset the top frame 4, turn off the pump body 81 and release the residual pressure in the auxiliary pressure component 8 by adjusting the switch 83 to complete the entire zirconia full crown bonding operation.
