Abstract

The invention discloses a tanb alloy dental implant and a tanb alloy dental implant material. The tanb alloy dental implant material comprises tantalum powder and niobium powder mixed with Ta:Nb=5.8-6.2:3.8-4.2, and the weight ratio of balance elements is less than 1. 5%; the powder particle sizes of the niobium powder and niobium powder are from 10 micrometers to 60 micrometers. The tanb alloy dental implant is prepared by a laser layered superposition selective zone melt forming process using the tanb alloy dental implant material.

Description

technical field [0001] The invention relates to the technical field of medical biomaterials, in particular to a tantalum-niobium alloy dental implant material and a tantalum-niobium alloy dental implant. Background technique [0002] In recent years, with the development of dental implant technology, dental implants have become one of the main repair methods for missing and defective dentition. Dental implants are usually anchored in the pre-opened holes on the patient's alveolar bone, and then worn correspondingly. crown to complete the restoration of the implant. Dental implants have the appearance and function of normal natural teeth, and are very popular among patients and dentists. [0003] With the development of social economy and the improvement of people's living standards, the requirements for medical care are getting higher and higher. In order to meet people's desire for health care, countries around the world have done a lot of work on the research and develop...
