Description of the Related Art When a tooth is lost due to a periodontal disease such as alveolar pyorrhea or an accident such as an accident, a treatment for filling and fixing a plastic artificial tooth to the missing portion of the tooth is performed. As a treatment for such a tooth defect, first, a dentist takes a tooth mold of a patient's tooth defect portion, a dental technician creates an artificial tooth by casting in accordance with the taken tooth mold, and the manufactured artificial tooth The general concept is a series of processes in which the dentist refills the patient and fixes it.

いる。Since the conventional treatment for a tooth defect is performed as described above, the treatment progresses from the dentist to the dental technician and then to the dentist again. There is a problem that it takes several days or more from the start to the end of treatment, and it is desired to realize a treatment method in which the treatment can be completed only on the side of the dentist.

定する。By the way, the present inventor has proposed a method for fixing a tooth which has become unstable due to periodontal disease or the like, in Japanese Patent Application No. 31621.
Proposed to No. 63. In this method, a shape memory process is provided in which notches are provided at both ends thereof and a pair of engaging legs are provided, and the engaging legs open in the mother phase state and the engaging legs close in the martensite phase state. Using the shape memory alloy member that has been applied, to form a cavity that communicates with the normal tooth and the unstable tooth to be fixed, insert the shape memory alloy member in the martensite phase state into this cavity, and insert The tooth fixing member is heated to open the engaging leg and fix the unstable tooth.

が充分であるとは言い難い。It is easily conceivable to apply such a fixing method to fix an artificial tooth. That is, cavities are formed in normal teeth on both sides of the tooth defect, and the engaging legs at both ends of the shape memory alloy member in the closed state are inserted into the cavities, and the shape memory alloy member is interposed with the adhesive resin. It is possible to fix the artificial tooth by opening the engaging leg and then heating after positioning the artificial tooth that has been penetrated. However, with this method, it is necessary to maintain the special shape memory characteristics of the shape memory alloy member, so there is a limit to the casting process, and it is not possible to obtain a surface shape for enhancing the adhesion with the resin, and the artificial tooth It is hard to say that is fixed enough.

The original state in which it was inserted into the formed cavity, the artificial tooth was filled with resin to cover the fitting member, the shape memory member was heated after the resin hardened, and the engaging leg was opened (mother phase state) Restore and fix the artificial tooth. This way,
The shape memory member is mechanically joined to the teeth on both sides, and the artificial tooth through which the shape memory member is passed is also securely fixed. Further, if the fitting member is provided with a shape device (formation of holes, unevenness of the surface) for enhancing the adhesiveness with the resin, the fixing of the artificial tooth becomes more reliable.

℃，40℃程度であるものを使用する。The Ni-Ti alloy is an ordered lattice alloy that undergoes martensitic transformation, which is generally called thermoelastic type. And this transformation has a property that the hysteresis of the forward and reverse transformation between the matrix phase and the martensite phase is small, and it is crystallographically reversible. Crystallographically reversible means that not only the crystal structure of the parent phase is restored by reverse transformation, but also the crystal orientation is restored. When shape memory processing is applied and cooled,
At the martensite phase start temperature (M s ), the martensite transformation starts and the deformation proceeds, and at the martensite phase end temperature (M f ), all of the martensite phase is formed. On the contrary, when the Ni-Ti alloy of the martensite phase thus deformed is heated, the reverse transformation starts at the reverse transformation start temperature (A s ),
At the reverse transformation end temperature (A f ), the state returns to 100% mother phase. At this time, in order to completely restore the original shape, it is necessary to heat to A f or higher. After returning to the 100% matrix, the reversibility peculiar to the thermoelastic martensitic transformation completely restores the original crystal shape while maintaining the connection between atoms, and the deformation is eliminated. In this embodiment, A s and A f are 20 respectively.
Use one that is about 40 ℃ or 40 ℃.
