    摘要： This invention relates to a base material composition for dental treatment comprising 100 parts by weight of alumina cement powder, 1-50 parts by weight of calcium type powder hardening retarder, and 1-20 parts by weight of hardening retarder for restraining dispersion of calcium ion. This composition has appropriate hardening time and consistency, and is higher in strength and lower in solubility. The composition gets hardened by low alkalinity and is very low in tissue irritation.

    摘要： An endosseous implant including at least an embedding portion to be embedded in a living tissue, the embedding portion comprising any of a platelike body itself and a desired shape of body obtained by working the platelike body, the platelike body having orderly or disorderly a plurality of substantially straight tubular channels passing through the thickness of the platelike body for permitting the ingrowth and penetration of the adjacent bone tissue therein, the tubular channels including at least two kinds of three different pore diameters of large, medium, and small pore diameters respectively for permitting the ingrowth and penetration of a bone tissue, osteoid tissue, and fibrous tissue, whereby a polycapillary structure is built by the ingrowth and penetration of the at least two of the three kinds of tissues which pass through the thickness of the platelike body after the implantation. According to the endosseous implant, there is provided a polycapillary structure which makes it possible for at least two of the bone, osteoid and fibrous tissue to pass through the thickness of the implant to make a biological dynamic connection of hard and soft tissues by the minial two kinds of the tissue. Futhermore the distribution of the tubular channels is set depending upon the stress imparted to said embedding portion, said distribution being such that channels small in pore diameter correspond to high impact stress, channels medium in pore diameter correspond to medium impact stress, and channels large in pore diameter correspond to low impact stress.
