療を行なえないという問題がある。For this purpose, as a method for administering a medicinal solution into the oral cavity, as described in Japanese Patent Publication No. 57-52060, for example, a cavity in which a medicinal solution can be sealed is formed in the denture, and a medicinal solution administration window that can be opened and closed at the tooth root of the denture is used. There is a method in which a drug solution is administered at the same time as the occlusal action. However, this method has the problem that the drug solution can only be administered during the occlusal action, and treatment cannot be performed by continuous drug solution administration.

Therefore, treatments for inflammation and diseases can be effectively carried out. Moreover, since the implant is integrally fitted and fixed to the upper part of the tooth, treatment can be performed without causing any discomfort to the patient. It is necessary to change the sustained release rate of the drug solution depending on the therapeutic purpose, and this can be done by changing the pore size of the ceramic that forms the incorporated material 2. When the drug solution runs out, the implant 2 can be taken out from the artificial tooth crown 1 and a new implant impregnated with the drug solution can be fitted and fixed, making it easy to extend the treatment period.

る。7 to 9 above, the entire artificial tooth crown is constructed of porous ceramics impregnated with a drug solution and capable of sustained release, and the drug solution is gradually absorbed through the gingival mucosa. Therefore, it is possible to effectively treat mucosal inflammation such as stomatitis and gingivitis, and mucosal cancer diseases. In the case of the eighth and ninth embodiments, the artificial tooth root 18 itself is also made of ceramics similar to the artificial tooth crown, and the chemical solution is impregnated into the artificial tooth root 18 or both with the artificial tooth crown. You can also do it. Artificial tooth root 1
When 8 is impregnated with a drug solution for sustained release, the drug solution leaches into the gingiva, making it possible to effectively treat cancer deep in the gingiva and alveolar bone cancer. When both are impregnated with a drug solution for sustained release, the drug solution is absorbed from both the gingival mucosa and the gingival region, making it possible to effectively treat a wide range of inflammations and diseases.
