<p>PURPOSE:To reduce the concn. of stress to the bone tissue around an artificial dental root or to the neck part of the artificial dental root and to make the absorption of the peripheral bone of the artificial dental root or the breakage of the artificial dental root hard to generate by mounting a connection member for connecting the heads of at least two ones among artificial dental roots and the head of a natural tooth so as to cover both of them. CONSTITUTION:Two rod-shaped artificial dental roots 1, 2 and one natural tooth 4 adjacent to the artificial dental root 2 are connected by a connection member 3. The connection member 3 connects the heads of the artificial dental roots 1, 2 and the head of the natural tooth 4 and is integrally formed. By this method, the heads of a plurality of the artificial dental roots and the head of the natural dental adjacent thereto or between both of them can be covered with and connected by the connection member made of a material for a living body and, therefore, the concn. of stress to the bone tissue around the artificial dental roots directly coming into contact with bone tissue or bonded thereto and the neck parts of the dental roots is extremely low.</p> |
