PROBLEM TO BE SOLVED: To improve both wear resistance and masticatory function for an artificial tooth without impairing the form, function and beauty of an existent artificial tooth, further to easily recover the masticatory function of an artificial tooth worn by mastication and to maintain the function for a long time in the artificial tooth after long- time use. SOLUTION: Actions to pressing and to crush food are required for masticating food when occlude the upper and lower maxillary teeth. For such actions, it is important to surely capture food with the upper and lower maxillary teeth and it is necessary just to make food hard to escape from an occlusion plane. Besides, in order to maintain an inter-maxilla distance, it is enough only to mutually locally contact the upper and lower maxillary teeth in the case of occlusion. On the basis of such thinking, a wire 20 of metal or rubber is inserted inside a tooth top 12 of an artificial tooth 10 in the state of partially exposing it on an occlusion plane 14 at one terminal part. Thus, food is captured on the top end of the exposed part of the wire by the artificial tooth in the case of occlusion and made hard to escape, sufficient pressing and crushing can be easily performed and the masticatory function and the inter- maxilla distance are maintained for a long time.
