Problems solved by technology

As we all know, dental implants are small in size, generally only about 2mm in diameter, and less than 1mm in the thinnest part, so it is prone to problems such as difficult control of surface treatment accuracy, out-of-tolerance dimensions, and uneven surface treatment.

Embodiment 1

[0006] Clean 30 pure titanium (brand TA2) dental implants with absolute ethanol in an ultrasonic oscillator for 2 minutes, take them out and air-dry them, then soak them in a solution with a mass ratio of ferric chloride: ferric sulfate: ammonium nitrate: citric acid: glycerine Alcohol: pure water in a beaker of acid etching solution close to 1:0.5:1:50:50:20, place the beaker in an ultrasonic oscillator for natural acid etching for 1 minute, then take out the dental implant and use it without Washed with water and ethanol to obtain a dental implant after surface treatment.

Embodiment 2

[0008] Clean 45 titanium alloy (brand TC4) dental implants with a metal cleaning agent in an ultrasonic oscillator for 3 minutes, take them out and air-dry them and soak them in ① The mass ratio is ferric chloride: ferric sulfate: ammonium nitrate: citric acid: acrylic acid Triol: Put pure water in a beaker of an acid etching solution close to 1:0.5:1:50:50:20, place the beaker in an ultrasonic oscillator for natural acid etching for 1 minute, and then take out the dental implant with a sterile Clean with water and ethanol, observe the surface treatment, if necessary, repeat step ① until the surface condition is satisfactory, and obtain the dental implant after surface treatment.

Abstract

The invention discloses a surface treatment method of a dental implant; the method is applicable to surface treatment of a dental implant, the treated dental implant gains enlarged contact area and improved binding force with alveolar bone, and the stability of the implant is enhanced. The method comprises: pre-cleaning the surface of the finished dental implant to remove surface metal debris, impurities, oil and the like, soaking the dental implant in a solution of iron chloride, ammonium nitrate, citric acid, glycerol and purified water in a mass ratio of 1:0.5:1:50:50:20, wherein the purity of the drug solution needs to be not less than level III (chemical purity), and treating the surface of the dental implant in an ultrasonic oscillator so that surface treatment uniformity is guaranteed.

Description

technical field [0001] The invention relates to a surface treatment method of a dental implant. Background technique [0002] The treatment of tooth loss with metal dental implants is recognized by doctors and patients. Prolonging the service life of implants and improving the bonding strength between implants and alveolar bone have always been the goals pursued by stomatologists. At the same time, It also reflects from the side that the contact area between the dental implant and the alveolar bone is insufficient, the bonding force needs to be improved, and the stability of the implant needs to be enhanced and other problems that need to be solved urgently. As we all know, dental implants are small in size, generally only about 2mm in diameter, and less than 1mm in the thinnest part, so it is prone to problems such as difficult control of precision in surface treatment, out-of-tolerance dimensions, and uneven surface treatment.
