<p>PURPOSE: To reduce a partition height and facilitate handling at the same time by accommodating the upper side part of a partition screw in a sleeve-form element, and fitting the partition screw to a fixed member through the sleeve- form element. CONSTITUTION: An artificial tooth root partition member 1 comprises a sleeve- form element 5 and a partition screw 7 for fixing the element to a fixed body 2. The upper side part of the sleeve-form element 5 is provided for a conical tubular part 17 and accommodated in a conical form region setting plane formed by a gold cap 4. The upper part of the partition screw accommodated in the gold cap 4 is formed by a cylindrical part 23 wider on the lower side, and the cylindrical part is adjacent to the internal tubular surface of the sleeve-form element 5. The sleeve-form element 5 is screwed in a hole of the fixed body 2 by the partition screw 7 by use of a fitting means. Thus, it is possible to obtain a partition member, the partition height of which is lower and which can be easily handled.</p> |
