Measuring method by using resonance of a resonance medium
First Claim
1. A method of determining a shape of an article based on resonant properties of an MRI contrast medium, comprising the steps of:
- providing said article, wherein said article is one of teeth, a prosthesis, a jaw bone, and an implant structure and wherein said article lacks or is short of hydrogen protons;
providing said MRI contrast medium which is rich in hydrogen proton;
supplying said article with said MRI contrast medium, wherein said MRI contrast medium is in a liquid state at least when said MRI contrast medium is supplied to said article;
measuring said MRI contrast medium with an MRI device; and
determining said shape of said article on the basis of a configuration of said MRI contrast medium.

Abstract
The present invention relates to a method and an apparatus for determining the shape of a tooth, a prosthesis, a jaw bone, or an implant structure with an Magnetic Resonance Imaging device. However, since these items lack a substantial number of protons, electrons, or molecules which can be detected by an Magnetic Resonance Imaging device, these items are supplied with an Magnetic Resonance Imaging contrast medium which is rich in such protons, electrons, or molecules. Therefore, once the Magnetic Resonance Imaging contrast medium is supplied to the tooth, prosthesis, jaw bone, or implant structure, the Magnetic Resonance Imaging device can measure the items by measuring the Magnetic Resonance Imaging contrast medium surrounding the items. Furthermore, an electrical circuit may be provided which can determine the shape of the tooth, prothesis, jaw bone, or implant structure based on the measurements of the Magnetic Resonance Imaging device. Also, a three dimensional cutter may be provided which can create a crown or other implant based on the shape determined by the electrical circuit.
