  First step (A): In order to kill microorganisms and the like in the surface of the crown 3 and the dental follow-up cavity 2, sterilization is performed by, for example, high-temperature and high-pressure saturated steam in an autoclave. This can prevent bacterial growth during long-term storage.

  Second step (B): The surface of the crown 3 and the inside of the tooth cavity 2 are immersed in a chemical such as 40% phosphoric acid gel for about 10 seconds for the purpose of mineral decalcification, and after the treatment, purified water is used. Wash with air and air dry.

  Third step (C): For the purpose of organic dissolution, the surface of the crown 3 and the inside of the dental cavity 2 are immersed in a chemical such as 10% sodium hypochlorite gel and subjected to an immersion treatment for about 2 minutes. Wash with purified water and air dry.

  Fourth step (D): For the purpose of recovering the enamel and dentin 4 on the surface of the crown 3 to the whiteness immediately after eruption, soak in a chemical such as 16% urea peroxide for about 12 hours. Later, it is washed with purified water and air-dried.

  5th process (E): After applying the dental adhesive which introduce | transduced the self-etching primer in the crown decay part 1 and the dental follow-up cavity 2, the dental using the photocurable resin whose elasticity modulus is substantially equal to a tooth Fill with composite resin for filling and restore the shape of the deciduous teeth.

  This self-etching primer treatment agent is used for the surface treatment of tooth enamel when the adhesive resin cement is adhered to the tooth enamel. Specifically, when an adhesive resin cement such as 4-META / MMA-TBB resin is adhered to a tooth enamel, an acidic monomer of methacrylate or acrylate such as 2-methacryloyloxyethyl phosphate, 2-hydroxy Adhesion of adhesive resin cement to enamel when the enamel is treated with a self-etching primer treatment agent with an aqueous solution containing a water-soluble monomer such as ethyl methacrylate or acrylate and a metal salt such as ferric chloride. It is widely known to improve strength and durability.

  6th process (F): The restoration process of the nano level | wound made in the tooth is performed by application | coating of the enamel improving agent to the crown 3 surface.

  By passing through the first step (A) to the sixth step (F) described above, a deciduous tooth form restoration P that can be stored stably for a long period of time is generated.

  Next, a process for treating deciduous teeth (generation of a deciduous tooth form restoration P) for enhancing the preservation of deciduous teeth will be described in comparison with a conventional example.

  Conventionally, the fifth step (E) is performed after the first step (A).
