見い出し、本発明に到った。In recent years, resin restoration materials for granites using acrylic thread monomers (for example, composite resins and resin cements) have come into widespread use, but a. Because of this, there was a problem that the surface of the filling material could not be sufficiently hardened during tooth filling. For composite resin restoration of grade 5 cavities on i4 teeth, the surface can be almost completely hardened by pressure feeding with strips, but for complex surface shapes such as the occlusal surface of Hizono and cement margins, it is difficult to apply pressure with strips. The above problem can be solved by applying a paste to the surface of the filler to cut off the contact between oxygen and the filler and completely harden the surface. Based on this idea, we tried various persimmon ingredients. As a result, a water paste containing two types of polyethylene glycol, low molecular weight and tonal appearance, has an excellent oxygen shielding effect, is easy to apply to the surface of the filling material or the contact interface, and is easily removed by washing with water in the oral cavity. The present invention was based on the discovery that this method has the following advantages.

It is a surface covering material for The surface coating material of the present invention is prepared by mixing and heating the above two types of polyethylene glycols and melting them together.
After forming a homogeneous solution, the solution is cooled to room temperature while stirring to precipitate the polymeric polyethylene glycol.
It can be prepared by forming a solid-liquid mixed system (paste-like).

布が困難となる。In the present invention, it is important that the surface coating material be obtained in the form of a paste with poor fluidity. A dental resin restorative material is filled into a tooth cavity and cured, but the dental cavity exists at various positions on the tooth. Therefore, the surface of the filled resin tends to be inclined or vertical. In order to cover surfaces that will bend, the surface coating material needs to be in the form of a paste with poor fluidity even when heated in the oral cavity, so that it can be applied thickly to the surface and does not block air. , I.J.

The purpose of mixing two polyethylene glycols having 100% polyethylene glycol is to obtain a darning paste, and the amount of the polymeric polyethylene glycol mixed is less than 2Q City-15i part (
Low molecular weight polyethylene glycol (4 parts per 100 parts) has too much fluidity to be applied to the resin surface, and conversely, if it exceeds 200 parts, the paste becomes hard and difficult to apply.

Such a restorative material is filled into the southern dental cavity and hardened, but after filling, by applying the coating agent of the present invention to the surface of the resin restorative material, the surface portion is isolated from air, so that it hardens. becomes complete. As a result, the weak layer on the resin surface caused by insufficient curing, which occurs in conventional methods that do not use such coating agents, does not come off due to friction, etc., and the surface coating agent of the present invention can be used. It will be possible to completely fill it.
