Description

Technical Field

[0001] The present invention relates to the technical field of implant dentures, and in particular to a segmented edentulous jaw implant bridge fixed denture. Background Art

[0002] In the field of oral implant restoration, edentulous jaw implant restoration is an important means to solve the problem of full-mouth tooth loss in patients. Currently, the common edentulous jaw implant bridge fixed dentures mostly adopt an integral structure. However, during the production process of the integral bridge, it is difficult to achieve completely accurate adaptation due to the complexity of the patient's jaw morphology, implant placement angle and position in the patient's mouth. Stress concentration is prone to occur at the connection between the bridge and the implant, causing the bridge or implant to bear unreasonable stress for a long time, increasing the risk of bridge breakage, implant loosening and even failure; in addition, once the integral denture is locally damaged or needs to be adjusted, it is often necessary to remove the entire denture and remake it. The maintenance cost is high and the cycle is long, which brings great inconvenience to the patient. In addition, the existing connection method is also insufficient in terms of stability and sealing, which can easily lead to food residues entering the connection part, causing oral hygiene problems and inflammation around the implant.

[0003] In order to solve the above problems, some segmented dentures have been studied. However, the existing segmented dentures have problems such as unreasonable segment design, complex and unstable connection structure, and poor coordination between segments. In addition, due to the use of private customized medical methods, the production cycle is long, which cannot meet the actual clinical needs well and is difficult to be widely promoted in actual production and application. Therefore, there is an urgent need to design a segmented edentulous jaw implant bridge fixed denture with a novel and reasonable structure, stable connection, and effective solution to the existing problems. Summary of the Invention

[0004] The purpose of the present invention is to provide a segmented edentulous jaw implant bridge fixed denture, which improves the adaptability of the denture to the patient's oral cavity, disperses stress, and reduces the risk of damage to the denture and implant through innovative segmented structural design and connection method; at the same time, it facilitates local repair and adjustment of the denture, improves the stability and sealing of the denture, improves oral hygiene, and improves the patient's comfort and repair effect.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] As a further technical solution of the present invention, the top surface of the connecting piece is provided with a truncated cone with an outwardly convex diameter as a connecting platform. After the connecting piece is installed on the top surface of the base, the top surface of the connecting piece is ground and fixedly connected to the denture crown. The denture crown is made of all-ceramic material and has good aesthetics and biocompatibility.

[0008] As a further technical solution of the present invention, the inner end of the connecting card rod is fixedly connected to an inner card plate, a card slot is provided on the inner card plate, the support card rod is clamped inside the card slot, a rectangular groove is provided at the bottom of the sealing card plate, and protrusions are provided on both sides of the sealing card plate.

After screwing the external hexagonal nut structural block, the threaded rod cannot be rotated due to the restriction of the slot, and at this time the position of the connecting sleeve and the fixed tube can be adjusted. After the connecting sleeve is separated from the fixed tube, the position of the card wheel can be adjusted by pulling the card wheel. After being fixedly engaged with the adjusting block, the connecting sleeve is rotated to fix it with the fixed tube to complete the position fixation of the card wheel.

[0011] As a further technical solution of the present invention, the outer wall of the implant is implanted into the patient's alveolar bone by opening a thread, and the connecting rod fixedly connected to the top of the implant is a metal rod made of titanium, but is not limited to titanium.

When subjected to force, each connecting bridge can independently disperse stress, avoiding the problem of stress concentration in the integral bridge, effectively reducing the risk of bridge breakage and implant loosening, and increasing the service life of the denture and implants.

[0014] Secondly, it is easy to repair and adjust: when the denture is partially damaged or needs adjustment, it is only necessary to dismantle the corresponding connecting bridge for repair or replacement without removing the entire denture, which greatly reduces repair costs and time and improves repair efficiency.

[0034] Please see the attached Figure 6 and attached Figure 7 The inner end of the connecting rod 61 is fixedly connected to the inner card plate 6101, and a card slot is provided on the inner card plate 6101. The support card rod 62 is clamped inside the card slot. A rectangular groove is provided at the bottom of the sealing card plate 63, and protrusions are provided on both sides of the sealing card plate 63. When the sealing card plate 63 is clamped to the top surface of the connecting rod 101, the support card rod 62 is clamped in the rectangular groove at the bottom of the sealing card plate 63, and the protrusions on both sides of the sealing card plate 63 are respectively clamped in the card slot of the inner card plate 6101 and the card slot on the inner wall of the rectangular groove of the connecting rod 101, and the sealing card plate 63 is used to achieve the sealing of the top surface of the connecting rod 101;

[0040] Working principle of the present invention:

[0041] In the early preparation stage, a high-precision three-dimensional scan is performed on the patient's oral cavity to obtain detailed data such as the position, angle, and jaw morphology of the implant 1. The data is then imported into the three-dimensional design software. Based on the distribution of the implant 1 and the jaw morphology, the bridge unit is divided in the three-dimensional design software. The adjustment block 4201 is clamped onto the clamping wheel 4101 to complete the angle fixation of the second connecting frame 42 and the first connecting frame 41. The bridge is assembled, and the implant 1 and the abutment 2 are connected to the connecting bridge 4 at the required position. The connection between the implant 1 or the abutment 2 and the connecting bridge 4 is completed by threaded connection.

[0042] During the installation stage, the supporting clamp rod 62 is used to push the inner clamp plate 6101 so that the clamping block at the outer end of the connecting clamp rod 61 is clamped into the groove at the top of the connecting part 3. After the clamping block is clamped into the clamping groove on the inner clamp plate 6101 and the clamping groove on the inner wall of the rectangular groove on the top surface of the connecting rod 101, the clamp between the connecting part 3 and the connecting rod 101 is completed. After the sealing is completed using the sealing clamp plate 63, the connecting rod 101 is made flush with the top surface of the connecting part 3. The adhesive is applied to the connecting part 3, the denture crown is accurately placed on the connecting part 3, the crown position and occlusal relationship are adjusted, and the denture installation is completed after the adhesive is cured.
