Description
また、前記基礎データは、前記口腔模型をスキャンした口腔模型スキャンデータを前記患者の頭蓋骨に対してCT撮影したCTイメージ上に融合することで得られる。
その際、前記歯科インプラントモジュールは、患者のCTデータと口腔模型または口腔を3Dスキャンしたイメージとを重畳することにより、インプラント診断及び仮想診断のための環境を具現することができる。
その際、前記切削ガイドを固定するためのホールと前記固定板を固定するためのホールは、少なくとも一対のホールが顎骨における同じ位置に形成されるようにデザインされる。
また、前記歯科医院サーバは、仮想顎矯正を行うに当って、それぞれの部分に切断された顎骨断片をプログラム上で移動及び回転させながら、仮想顎矯正を行うことができる。
その際、前記顎矯正補助装置は、実際の顎矯正遂行で各顎骨を切断するための切削ガイドと、切削ガイドによって切断された顎骨の各部分を仮想顎矯正を通じて移動させた後、顎骨を固定する固定ピンの位置を案内するための顎骨固定板(fixation plate)及び顎骨固定板を固定する時、上・下顎弓の仮想顎矯正位置の固定のために、上・下顎の間に挟まれる臨時固定体としての顎弓固定板(intermittent stent)と、を含んで構成することができる。
図1は、本発明の実施形態による3次元ハイブリッド映像構築プログラムを利用した顎矯正システムの構成を概略的に示す図面である。
CT撮影装置101は、顎矯正診断計画樹立のために、顎矯正対象患者の頭蓋骨に対するCT撮影を行う。
図2は、本発明による3次元ハイブリッド映像構築プログラムを利用した顎矯正システムに基づいて顎矯正を行う過程を示すフローチャートである。
また、前記顎矯正装置製作会社によって製作された顎矯正補助装置は、図12の(A)、図12の(B)のように、実際の顎矯正で各顎骨を切断するための切削ガイド110a〜110cと、図12の(C)のように、切削ガイド110a〜110cによって切断された顎骨の各部分を仮想顎矯正を通じて移動させた後、顎骨を固定する固定ピンの位置を案内するための顎骨固定板120a〜120d及び顎骨固定板120a〜120dを固定する時、上・下顎弓の仮想顎矯正位置の固定のために、上・下顎の間に挟まれる臨時固定体としての顎弓固定板130と、を含んで構成される。
