Description

Technical Field

[0001] This utility model relates to an implant crown bonding and fitting aid, belonging to the field of oral clinical technology. Background Technology

[0002] Dental implants are now widely used. However, the traditional process for bonding the crown portion of a dental implant involves multiple steps: sealing, applying adhesive, waiting for curing, grinding away the sealing adhesive, drying, and then resealing with liquid resin. This process is inefficient, and the adhesive may not be completely removed during the grinding process, leading to complications such as the subsequent sealing material falling off. Utility Model Content

[0003] In order to solve the above-mentioned problems in the existing technology, this utility model provides a dental implant crown bonding and fitting aid, which can simplify the fitting process and improve the sealing efficiency.

[0004] The technical solution of this utility model is as follows:

[0005] A dental implant crown partial bonding fitting aid includes a gingival portion and a crown portion. The gingival portion contains an implant, and the top of the implant has an abutment. Screw channels are formed inside the implant and the abutment. The crown portion has a pre-drilled through-hole, through which it is installed on the outside of the abutment. A space is reserved at the top of the crown portion for filling with fluid resin. The fitting aid also includes a fitting aid rubber ring and a connecting part located at the bottom of the rubber ring. Filling material is installed at the bottom of the connecting part. The fitting aid is used to insert into the screw channel and cause the filling material to automatically disconnect.

[0006] The dental assist device also includes a dental assist occlusal part, with an assist rubber ring disposed at the bottom of the dental assist occlusal part, and the diameter of the dental assist occlusal part being larger than the diameter of the assist rubber ring.

[0007] The outer wall of the auxiliary rubber ring is in close contact with the inner wall of the screw channel.

[0008] The height of the auxiliary rubber ring is 2mm.

[0009] The portion of the bite part of the dental assist device that extends beyond the screw channel is vertically perforated with an overflow hole.

[0010] The filling material is spirally rolled up, and its upper and lower ends are divided into an inner concave connecting end and an outer convex extrusion end. The inner concave connecting end and the outer convex extrusion end are mutually fitting tower-shaped cones. The connecting part is an inverted cone structure and is connected to the inner concave connecting end.

[0011] The dental assist device has a circular ring at the top outer end of the occlusal part, and the overflow hole is provided through the circular ring and the occlusal part of the dental assist device.

[0012] This utility model has the following beneficial effects:

[0013] This invention improves sealing efficiency by combining a dental aid with filling material and pressing to separate the filling material from the connecting part.

[0014] This invention uses an auxiliary rubber ring to prevent adhesive residue from remaining in the screw channel, simplifying clinical procedures. In addition, the fixed rubber ring has a height of 2mm, which provides a good height reference for the sealing fluid resin, ensuring the strength of the fluid resin; it can also quantify the thickness of the fluid resin, making it convenient for future disassembly.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] Please see Figures 1 to 2 The utility model provides a technical solution:

[0021] The existing structure includes a gingival portion 1 and a crown portion 3. An implant 2 is housed inside the gingival portion 1, and an abutment is located on top of the implant 2. Screw channels are formed inside both the implant 2 and the abutment. A through-hole is provided in the crown portion 3, through which the crown portion 3 is installed onto the outside of the abutment. A space is reserved on top of the crown portion 3 for filling with fluid resin.

[0022] The current clinical bonding and placement process involves the following steps: After initial clinical work, an appropriate amount of filling material is selected based on experience, and the screw channel is sealed with the selected material. The through-hole walls of crown portion 2 are then coated with adhesive, and crown portion 2 is pressed into the abutment. Cotton is placed on top of crown portion 2, and the patient's biting is used to confirm its placement. Because the through-hole walls of crown portion 2 are coated with adhesive, excess adhesive will be squeezed into the screw channel when crown portion 2 is pressed into the abutment. Therefore, after the adhesive has cured, it needs to be removed from the screw channel using a high-speed machine. Finally, the through-hole and screw channel are sealed with fluid resin to complete the process.

[0023] The device also includes a dental assist device, which includes an assist device rubber ring 5 and a connecting part 6 located at the bottom of the assist device rubber ring 5. The outer wall of the assist device rubber ring 5 is tightly fitted with the inner wall of the screw channel. Dental filling material 7 is installed at the bottom of the connecting part 6. The dental assist device is used to insert into the screw channel and cause the dental filling material 7 to automatically disconnect. Specifically, the dental assist device also includes a dental assist device bite part 4. The assist device rubber ring 5 is located at the bottom of the dental assist device bite part 4, and the diameter of the dental assist device bite part 4 is larger than the diameter of the assist device rubber ring 5.

[0024] Specifically, the through-hole wall of the crown portion 2 is coated with adhesive. The crown portion 2 and the dental appliance are then placed together into the implant 2 and abutment. The patient confirms the placement of the crown portion 2 by biting down on the occlusal part 4 of the dental appliance. The integrated occlusal part 4 of the dental appliance replaces cotton for manipulation. Simultaneously, because the outer wall of the rubber ring 5 of the appliance fits tightly against the inner wall of the screw channel, the adhesive will not enter the screw channel, thus eliminating the need for the step of removing the adhesive from the screw channel using a quick-release machine. Furthermore, since the portion of the occlusal part 4 of the dental appliance extending beyond the screw channel has a vertically penetrating overflow hole, the adhesive on the crown portion 2 will be discharged outward through the overflow hole. Then, under the action of biting down, the filling material 7 automatically breaks off within the screw channel. After the adhesive has cured, the remaining dental appliance is removed, and the through-hole and screw channel are sealed with fluid resin to complete the process.

[0025] The auxiliary rubber ring 5 is 2mm high. The purpose of setting the auxiliary rubber ring 5 to 2mm is to provide a certain space for the subsequent filling and sealing of fluid resin.

[0026] Specifically, the filling material 7 is spirally rolled up, with its upper and lower ends divided into an inwardly concave connecting end 8 and an outwardly convex extrusion end 9. The inwardly concave connecting end 8 and the outwardly convex extrusion end 9 are mutually fitting tower-shaped cones. The connecting part 6 has an inverted cone structure and is connected to the inwardly concave connecting end 8. When the connecting part 6 and the filling material 7 enter the screw channel, the contact and extrusion between the bottom of the filling material 7 and the bottom of the screw channel causes the tower-shaped concave outwardly convex extrusion end 9 to deform toward the connecting part 6 and drive the inwardly concave connecting end 8 to rotate. Since the connecting part 6 has an inverted cone structure, when the outwardly convex extrusion end 9 is under force, it will provide the inwardly concave connecting end 8 with the force to detach from the connecting part 6, thus allowing the filling material 7 to detach from the connecting part. It is worth mentioning that the connection between the connecting part 6 and the inwardly concave connecting end 8 is not tight, similar to the connection method of Teflon tape in existing technology. Before the overall operation, a certain length of filling material 7 can be pre-rolled according to the doctor's experience. When needed, the required amount of filling material 7 can be used based on the doctor's experience.
