Problems solved by technology

These methods can inhibit the adhesion of bacteria to a certain extent, improve the biocompatibility of dental implants, and induce the growth of bone tissue, but these methods often lose sight of the other, and have problems such as poor chemical stability and poor controllability.
For example, CN 102676986 discloses a method for preparing a silver-infiltrated layer on the surface of a titanium dental implant, which can effectively inhibit the adhesion of bacteria on the surface of the implant material, but the release rate of silver ions is uncontrollable and will be released in large quantities at the initial stage of implantation, maintaining The anti-infection time is short and the biocompatibility is poor (Biomaterials 2011, 32: 9810-9817); as another example, the dental implant sprayed with hydroxyapatite on the titanium surface can adapt to the natural remodeling of the surrounding bone and maintain bone mass, but the implant Tooth has the problem that the coating is easy to degrade, and the anti-infection performance cannot meet the needs

Abstract

The invention discloses a preparation method of a dental implant capable of being used for diabetic patients. The method comprises the following steps that an amino catechol compound, an organic cationic antibacterial agent and a buffer solution are mixed to obtain a dipping solution; a dental implant body is put into the dipping solution to be dipped for 12 h to 36 h at the temperature ranging from 18 DEG C to 37 DEG C, and a dipped dental implant is obtained; ultrasonic washing is conducted on the dipped dental implant with absolute ethyl alcohol and deionized water, drying is conducted at room temperature, and then the dental implant capable of being used for the diabetic patients is obtained. The preparation method is simple, easy to operate, capable of saving energy, low in carbon and free of pollution, and the dental implant prepared through the method has the good anti-infection performance and biocompatibility and can be used for the diabetic patients.

Description

technical field [0001] The invention relates to the field of preparation of dental implants. More particularly, it relates to a method for the preparation of dental implants for diabetic patients. Background technique [0002] Dental implant technology has become a routine means of repairing missing teeth in the oral cavity. A large number of experimental studies and clinical cases have proved that the success rate of dental implants is mainly affected by the following two factors: First, oral bacteria are easy to colonize around the implants, and even form biofilms, causing peri-implantitis and peri-implant mucosa First, the biocompatibility of the implant is poor, and the combination with the alveolar is poor, resulting in slow osseointegration and healing after implantation. [0003] For diabetic patients, the success rate of dental implants is significantly lower than that of normal edentulous patients. On the one hand, high blood sugar is conducive to the reproduction...
