FIXTURE FOR DENTAL IMPLANT

PROBLEM TO BE SOLVED: To provide a dental implant fixture with which another fixture may be implanted without additional drilling when implantation of a fixture fails.SOLUTION: A dental implant fixture comprises: a body 120; a continuous thread part 130 formed having no gap section on an outer circumferential direction of the body; a bone damage prevention part 170 formed at one end portion of the body and preventing an alveolar bone existing in an opening area of a hole where the body is implanted from being damaged due to the continuous thread part; and an entrance direction guide part provided at the other end portion of the body in a predetermined section in a longitudinal direction from a tip part of the body and guiding the body in an initial implantation entrance direction. The entrance direction guide part 160 comprises: a flat portion formed horizontally flat; an inclined portion 162 extending upward from a circumferential surface of the flat portion 161 with an upwardly increasing radius; and a curved portion 163 connecting the inclined portion and the continuous thread part and having at least one area inwardly curved inward in the radius direction. The body is arranged in a tapered shape. A line connecting tip parts of the continuous thread part forms a taper inclination line.SELECTED DRAWING: Figure 5 【課題】植立が失敗しても、再び穿孔せずに、次のフィクスチャーを植立することができる歯科用インプラントのフィクスチャーを提供する。【解決手段】胴部１２０と、胴部の外面に断絶区間なしに形成される連続ネジ部１３０とを含み、胴部の一端部に、連続ネジ部によって胴部が植立されるホールの開口部の歯槽骨の損傷を阻止する骨損傷阻止部１７０を含み、胴部の他端部に、胴部が、胴部の先端部から長手方向に所定の区間に、胴部に対する初期の植立進入方向を案内する進入方向案内部が形成され、進入方向案内部１６０は、水平方向に平坦に形成される平坦部と、平坦部１６１の周り面から上方に行くほど半径が広くなる傾斜部１６２と、傾斜部と連続ネジ部とを連結し、少なくとも一領域が半径方向内側に湾曲する湾曲部１６３とを含み、胴部はテーパー状に設けられ、連続ネジ部の先端部を連結するラインは、テーパー傾斜ラインを形成する構成とする。【選択図】図５
