▎ 摘　　要

NOVELTY - The graphene (2) is used as a material to fill and to seal a tooth cavity. An insulation and securing unit are secured to adjacent natural teeth, so as to provide the physical strength. An insulation and securing unit is provided for securing the structure of bridge to adjacent natural teeth, and is elevated above the gum except for a number of support points sit on gum (5). USE - Graphene used as material for dental cap, and used in dental bridge, denture, dental implant and dental filling (all claimed). ADVANTAGE - The foodstuff is prevented from entering into the tooth cavity. The natural look of the tooth is preserved by the transparent nature of graphene. DESCRIPTION OF DRAWING(S) - The drawings show the schematic views of the graphene. Artificial tooth (1) Graphene (2) Socket cavity (3) Jawbone (4) Gum (5)
