Problems solved by technology

However, after the "dental implant" is implanted in the human body, how to quickly and effectively form the optimal surface pore size and roughness for osseointegration, so as to obtain better initial and long-term stability after healing, has not yet reached a clear conclusion. The pursuit of " Various surface modification methods and process parameters of dental implants are still the subject of research in recent years

Embodiment 1

[0040] First, the artificial aggregate is subjected to sandblasting, and then the artificial aggregate is soaked in the first acid liquid sulfuric acid (concentration: 95 to 99%) at a temperature of 100 to 120°C for 5 to 60 minutes, followed by ultrasonic vibration Machine, using pure water and alcohol as the medium to clean and wet the artificial aggregate, after that, soak the artificial aggregate in the second acid liquid hydrochloric acid (concentration: 36 to 40%) at a temperature of 80 to 100°C5 minutes to 60 minutes. Then, an ultrasonic oscillator is used to clean and moisten the artificial aggregate with pure water and alcohol as the medium, so as to obtain the artificial aggregate after surface treatment.

[0041] The surface roughness of the artificial aggregate obtained in Example 1 was measured with an optical three-dimensional surface roughness measuring instrument, and the results are shown in Table 1. The surface roughness of the artificial aggregate obtained i...

Embodiment 2

[0048] The specific steps are the same as in Example 1, except that the first acid solution used is hydrochloric acid (concentration is 36 to 40%), the treatment temperature is 80 to 100°C, and the soaking time is 5 minutes to 60 minutes. It is sulfuric acid (concentration of 95 to 99%), the treatment temperature is 100 to 120°C, and the soaking time is 5 minutes to 60 minutes.

Abstract

The invention provides a surface treatment method of an artificial bone material. The method comprises the following steps: 1, providing the artificial bone material; and 2, sandblasting the artificial bone material, carrying out first acid corrosion treatment on the artificial bone material by using a first acid solution, and carrying out second acid corrosion treatment on the artificial bone material by using a second acid solution, wherein the first acid solution and the second acid solution are two acidic solutions in order to form a plurality of micro-pores on the surface of the artificial bone material. The invention also provides a surface treated artificial bone material.

Description

technical field [0001] The invention relates to an artificial aggregate and a treatment method thereof, in particular to a surface-treated artificial aggregate and a surface treatment method thereof, and the method is suitable for mass production. Background technique [0002] In the field of dental treatment nowadays, in addition to the traditional "fixed prosthesis" or "removable denture" for the treatment of tooth defects, "Dental Implant" has gradually become one of the mainstream options for dental treatment. . [0003] Looking back, in 1969 Branemark published the research results on titanium alloy "dental implants", which opened a new era of "dental implants". In 1972, Predecki et al. observed experimentally that an irregular "dental implant" surface can promote faster bone growth and have good mechanical fit and adhesion. In 1976, Schroeder et al. first observed the direct contact between bone and "dental implant" in tissue sections. And in 1992, Bower et al. also...
