METHOD FOR DENTAL IMPLANT PARTS MANUFACTURE Russian patent published in 2017 - IPC A61C8/00 A61C13/08 

FIELD: medicine.

SUBSTANCE: method for manufacture of a zirconium dental implant body includes the step of zirconium hydroxide surface layer provision with hardness less than that of the zirconium substrate by implant surface exposure to laser radiation. Prior to laser irradiation, the implant is fixed to the end of the rotating shaft of the electric motor, and during irradiation, it is uniformly rotated under the laser beam. At that, during implant irradiation, its surface is continuously treated with water vapour. After the specified time is expired, before the implant is installed, the implant surface, its pores and microcracks are coated with a drug by placing the implant in a capsule filled with a medicinal solution or biologically compatible solution containing solid microparticles of elements with bactericidal and anticoagulant properties, sealed, exposed to ultrasonic vibrations with frequency above the frequency of the cavitation threshold in the range of 20 kHz to 100 kHz, and the intensity of this ultrasound lies in the region of stable cavitation of 1.5 W/cm² to 2.5 W/cm². Then, after 3-5 minutes, ultrasonic vibrations generation is stopped, the solution is drained from the capsule, and the implant with the applied liquid-phase film is removed from the container and installed into a pre-formed bone channel. The invention allows to create a thin layer of zirconium hydroxide on the surface of a zirconium implant made, with hardness less than that of the patient's alveolar bone. Numerous cracks and pores are created on the formed implant layer under the influence of laser radiation and water vapour, where particles of medicinal solution or of biologically compatible solution containing solid microparticles of elements with bactericidal and anticoagulant properties penetrate under the influence of ultrasound.

EFFECT: improved implant biocompatibility with the tissues of patients, reduced time and quality of implant fusion with bone tissues, excluded implant rejection.
