Dental implant angle abutment made of molybdenum-rhenium alloy material

Abstract

The utility model discloses a dental implant angle abutment made of molybdenum-rhenium alloy material, which comprises an abutment upper structure and an abutment lower structure which are connected from top to bottom, the abutment upper structure comprises a truncated cone section and a connecting section, the lower end of the truncated cone section is connected with the connecting section, the connecting section and the truncated cone section are not coaxial, and the lower end of the truncated cone section is connected with the abutment lower structure. The connecting section is in threaded connection with the top of the abutment lower structure; the abutment upper structure and the abutment lower structure are both made of molybdenum-rhenium alloy materials. The dental implant is beneficial to angle matching of a long axis of a root crown after the implant is placed, ensures that the dental implant and surrounding bone tissues realize bony combination in the early stage and the soft tissues around an abutment are closed and combined, and effectively reduces occlusal force to bone structures around the implant and bone tissues around the abutment. Particularly, the long-term stable natural fusion state between the implant and the skeleton can be more prominently consolidated by stress interference of bone tissues around the neck of the implant and resistance to invasion of adverse factors of the oral environment.

Description

Technical Field

[0001] This utility model relates to the field of implant technology, and in particular to an angled abutment for a dental implant made of molybdenum-rhenium alloy. Background Technology

[0002] The abutment of a bone-plane dental implant is an essential component of a modular root-shaped bone-plane dental implant. It precisely connects to the corresponding internal interface within the implant root via a specially shaped hollow or solid connector. The solid connector abutment screws directly into the corresponding interface of the implant, creating a tightly integrated structure (achieving a cold-welding effect) where the abutment and implant root are two solid entities. This facilitates the assembly and retention of the crown on the abutment (through bonding or screw fixation) and also supports the fixation of other types of prosthetic frameworks, ultimately ensuring the complete anatomical and physiological functions of the dental implant structure.

[0003] Molybdenum rare earth materials possess many unique properties. Among them, the high strength, excellent toughness, ductility, and biocompatibility of Mo-50 Re alloy have been discovered in recent years to make it an excellent alternative to traditional implant materials. In 2018, MiRus, a medical device manufacturer in Atlanta, Georgia, reported a new application for a molybdenum-rhenium alloy at body temperature. Based on its mechanical and biological properties, cardiovascular stents made from Mo-50 Re alloy passed clinical evaluation, met ASTM standards, and obtained application certification. Utility Model Content

[0004] To overcome the aforementioned shortcomings, this invention aims to provide a dental implant angle abutment made of molybdenum-rhenium alloy. This abutment effectively achieves integrated connection of all parts of the dental implant, facilitating post-implant placement angle adjustment of the root-crown long axis. It ensures early osseointegration between the implant and surrounding bone tissue, as well as closed integration of the soft tissue around the abutment. This effectively reduces stress interference from occlusal forces on the surrounding bone structure, especially around the implant neck, and resists adverse factors in the oral environment, thus more significantly solidifying the long-term, stable, and natural fusion between the implant and bone. Furthermore, it allows for easy angle adjustment to accommodate crowns with different structures.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dental implant angle abutment made of molybdenum-rhenium alloy includes an upper abutment structure and a lower abutment structure connected from top to bottom, wherein: the upper abutment structure includes a truncated conical segment and a connecting segment, the lower end of the truncated conical segment is connected to the connecting segment, the connecting segment is not coaxial with the truncated conical segment, and the connecting segment is threadedly connected to the top of the lower abutment structure;

[0007] Both the upper and lower structures of the base are made of molybdenum-rhenium alloy.

[0008] Preferably, the truncated conical segment has a hollow structure.

[0009] Preferably, the lower end of the truncated conical segment is the larger end.

[0010] Preferably, the truncated conical segment and the connecting segment are manufactured integrally.

[0011] Preferably, the connecting section is provided with an external thread, and the top of the lower structure of the base is provided with an internal thread that is adapted to the external thread.

[0012] Preferably, the angle between the axis of the truncated conical segment and the axis of the connecting segment is not less than 5°.

[0013] More preferably, the angle between the axis of the truncated conical segment and the axis of the connecting segment is 5°, 15°, 20°, 25°, 30°, 35° or 40°.

[0014] Preferably, the connecting segment is a cylinder with a length of 1-5 mm and a diameter of 4-7 mm.

[0015] Furthermore, the lower structure of the base is a hollow structure and is provided with external threads.

[0016] Preferably, the lower structure of the base is screw-shaped.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This utility model can effectively connect the various parts of the dental implant, which is beneficial for adjustment during implantation and ensures the dental implant is firm and durable.

[0019] 2. This invention causes less interference to the placed bone structure and can more prominently integrate with the natural shape of the bone, achieving bony integration.

[0020] 3. The lower structure of the abutment of this utility model is a hollow hexagonal shape with a tapered ground groove for double fixation, which is conducive to connection with the corresponding insertion port built into the root of the bone plane implant. Attached Figure Description
