Description

 Specification

 Dental tooth surface coating kit

 Technical field

 The present invention relates to a dental coating material. More specifically, it is used for improving the aesthetics of teeth, such as giving gloss to teeth and adjusting the color tone by applying to teeth, for protecting !, dental coating materials, dental etching agents, dental The present invention relates to a dental coating kit, which may include a primer for dental use, a dental adhesive, and the like.

 Background art

 [0002] In recent years, there has been an increasing aesthetic demand for higher awareness of healthy teeth !, an increase in the number of Japanese people, and an improvement in the color tone of natural tooth surfaces.

Methods for improving the color tone of the natural tooth surface include (1) a method using a chemical solution such as hydrogen peroxide solution, and (2) a method of attaching a prosthesis called a laminate veneer. Among them, (2) the laminating base method is a method of adhering a porcelain resin having a small thickness to the dentin, and is excellent in aesthetics (for example, see Non-Patent Documents 1 and 2). ₀

 [0003] Further, in order to further enhance the aesthetics, there has been an increasing demand for making the tooth surface (enamel) shiny. In such a case, the artificial material is loaded on the tooth material by a method such as coating the surface of the tooth material with a laminating base method or a dental composite resin.

 In the case of the laminating method, the tooth material must be cut by the thickness of the porcelain resin, and (2) the porcelain resin, that is, the prosthesis is produced. In order to do so, high technical skills are required, (3) complicated processing steps are required, and (4) treatment costs are high.

[0004] In addition, in the case of a method of coating a tooth surface using a dental composite resin, (1) uneven coating and uneven thickness are easily generated, and (2) the tooth surface is cut because the coating layer is thick. There was a problem that had to be done.
