Problems solved by technology

However, due to the complex geometry of the denture framework, traditional mechanical polishing techniques are difficult to efficiently achieve a fully effective machining of the component surface
In addition, some of these technologies include electrochemical processing technologies, which use harmful chemicals including strong acids or bases, which are dangerous to operate and not environmentally friendly.

Abstract

The invention relates to the technical field of metal material surface treatment, in particular to an electrolyte plasma polishing method for a pure titanium denture support. In order to obtain the efficient, environment-friendly and simple polishing pure titanium denture support, the method comprises the following steps of (1) carrying out mechanical grinding; (2) carrying out ultrasonic cleaning; (3) drying; (4) carrying out electrolyte plasma polishing, wherein a polishing solution is a mixed aqueous solution of ammonium fluoride and potassium fluoride; the concentration of the ammonium fluoride aqueous solution is 3 to 18 g/L, and the concentration of the potassium fluoride dihydrate aqueous solution is 25 to 100 g/L; (5) carrying out ultrasonic cleaning; and (6) drying and carrying out vacuum sealing preservation to obtain a finished denture support with a bright mirror surface.

Description

technical field [0001] The invention belongs to the technical field of metal material surface treatment, and in particular relates to an electrolyte plasma polishing method for a pure titanium denture bracket. Background technique [0002] Dental defect is a common oral disease in middle-aged and elderly people. With the development of population aging in my country, the number of patients wearing removable dentures is increasing year by year. Pure titanium has good biocompatibility, high corrosion resistance, and light specific gravity. It has become an indispensable material for dental implants, and pure titanium brackets are more and more widely used. [0003] The environment in the oral cavity is one of the most complex microbial clusters in the human body. Wearing dentures in the mouth will cause the micro-ecological balance in the oral cavity to be out of balance, and easily cause dental caries, denture stomatitis and other diseases. At present, most of the widely use...
