<p><P>PROBLEM TO BE SOLVED: To provide a crown prosthesis structure for performing the fitting and connecting work or separating work of an abutment and a denture base, by simple work, a construction method of the structure, and a disassembly method of the crown prosthesis structure for disassembling the once constructed prosthesis structure for repair. <P>SOLUTION: The crown prosthesis structure includes: the rod-like post of a fiber material fixed in a planted state through an adhesive in a root canal in a vertical hole shape formed in a tooth root; an abutment roughly in a truncated conical shape for mounting a denture, which is connected to the upper surface of the tooth root through the rod-like post; a denture base which has a fitting hole formed at the bottom part and is formed to be freely suitable for the abutment; and the denture mounted on the denture base. Also, the abutment and the denture base are configured to be freely detachably mounted and fixed through tapered fitting structures closely attached to each other. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
