PROBLEM TO BE SOLVED: To provide an abutment teeth gauge that enables a worker to grasp a grinding amount of teeth in the process of forming abutment teeth.SOLUTION: An abutment teeth gauge 1 is placed astride each occlusal surface of a plurality of molar teeth 31 for forming the dentition. The plurality of molar teeth 31 contain a first molar tooth 31A, and includes a first close contact surface 11A capable of closely contacting the occlusal surface 31A1 of the first molar tooth 31A, a first buccal sidewall 12A rising up from the buccal end of the first close contact surface 11A, and a first lingual sidewall 13A rising up from the lingual end of the first close contact surface 11A. A first buccal ridge line 15A is formed in the boundary between the first close contact surface 11A and the buccal sidewall. A first lingual ridge line 16A is formed in the boundary between the first close contact surface 11A and the lingual sidewall. The first buccal ridge line 15A and the first lingual ridge line 16A can be placed so as to be positioned in the occlusal surface 31A1 of the first molar tooth 31A in the abutment teeth gauge.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】支台歯が形成される過程において、作業者が歯の研削量を把握することを可能にする支台歯形成ゲージを提供すること。【解決手段】歯列を形成する複数の臼歯31のそれぞれの咬合面に跨って載置される支台歯形成ゲージ1であって、複数の臼歯31は、第1臼歯31Aを含み、第1臼歯31Aの咬合面31A1に密着可能な第1密着面11Aと、第1密着面11Aの頬側端部から立ち上がる第1頬側側壁12Aと、第1密着面11Aの舌側端部から立ち上がる第1舌側側壁13Aと、を備え、第1密着面11Aと頬側側壁との境界には第1頬側稜線15Aが形成されており、第1密着面11Aと舌側側壁との境界には第1舌側稜線16Aが形成されており、第1頬側稜線15A及び第1舌側稜線16Aは、第1臼歯31Aの咬合面31A1に位置するように載置可能な支台歯形成ゲージ。【選択図】図1
