On the issue of the chemical structure of braces

The article presents a review of the of the chemical structure of braces systems currently used in dentistry. At the moment, braces are one of the most commonly used orthodontic structures in the treatment of defects in the dental system. The following requirements apply to braces: strong adhesion to the hard tissues of teeth, biocompatibility, atraumatism, ease of fixation and use, convenience in carrying out individual and professional oral hygiene. Metals, plastics (polycarbonate, polyurethane), ceramics can serve as materials for the manufacture of braces. The main advantages of metal braces are biocompatibility and modified adhesion, while ceramic and plastic braces offer high aesthetics. The main disadvantage of plastic braces is the low structural strength, as well as the toxicity of bisphenol, which is a monomer of polycarbonate. The disadvantages of metal braces include a low level of aesthetics. The main disadvantage of ceramic braces is the risk of chipping the enamel or crown of the tooth when removing the structure due to its high adhesion to the hard tissues of the tooth. Currently, in the Russian Federation, due to import substitution, it is particularly relevant to manufacture our own, domestic braces with improved biocompatibility and adhesion to hard dental tissues, as well as caries prevention at the place of braces installation.
