PROBLEM TO BE SOLVED: To provide a tooth alignment model input device which makes use of the fact that an accurate shape of a tooth alignment model can be obtained as digital data by using penetrating X-rays so as to maintain a positional relation in an articulator for the tooth alignment model, and thereby which can take radiograph with a dental X-ray CT device.SOLUTION: The tooth alignment model input device includes: a mounting plate installation part 12 set up to the articulator for installing the mounting plate of the tooth alignment model a tooth alignment model supporting body 14 for maintaining the same installation condition as that of the articulator, while the tooth alignment model is installed in the mounting plate installation part 10 and a tooth alignment model input table for installing the tooth alignment model supporting body 14 in a jaw supporting part of the dental X-ray CT device on which the jaw is disposed to fix the position of the teeth.COPYRIGHT: (C)2013,JPO&INPIT【課題】透過性のX線を適用することにより歯列模型の正確な形状をディジタルデータで取得できることを利用し、歯列模型の咬合器における位置関係を維持し、歯科用X線CT装置により撮影可能な、歯列模型入力装置の提供。【解決手段】歯列模型のマウンティングプレートを取り付けるために咬合器に備えられているマウンティングプレート取付部12と、マウンティングプレート取付部10に歯列模型を取り付けた状態で、咬合器における状態と同じ取り付け状態を維持するための歯列模型支持体14と歯列模型支持体14を、歯科用X線CT装置の顎を載せて歯の位置を固定する顎支持部に取り付ける歯列模型入力用テーブルとを備える。【選択図】図3
