Claims (5)
- 上顎(2)及び下顎(3)を含む歯の状況の全体撮像(50)のための個々の三次元光学撮像(1)を記録するための方法であり、前記上顎(2)の第1の部分の第1の仮想三次元モデル(6)と、前記下顎(3)の第2の部分の第2の仮想三次元モデル(8)とが個々の撮像から形成される、方法であって、前記第1の仮想三次元モデル(6)と前記第2の仮想三次元モデル(8)との間の幾何学的な位置関係が特定され、前記位置関係の特定が、接触パターンを用いて行われ、前記接触パターンが、前記上顎(2)と前記下顎(3)との間に複数の接触範囲(31、32)を含んでおり、咬合紙(29)を前記上顎(2)と前記下顎(3)との間に配置してから前記上顎(2)及び前記下顎(3)を咬合位置にすることで、前記接触パターンが前記咬合紙(29)によって測定され、つづいて、前記咬合紙(29)を取り除いた後で個々の撮像(1)の測定が行われ、その結果、前記上顎(2)及び前記下顎(3)での接触パターンの接触範囲が検出され、前記上顎(2)及び前記下顎(3)における接触範囲の位置を特定するために、形成された第1の仮想三次元モデル(6)及び形成された第2の仮想三次元モデル(8)が、コンピュータ(10)によって解析され、検出された幾何学的な位置関係を考慮して前記第1の仮想三次元モデル(6)及び/又は前記第2の仮想三次元モデル(8)が変形されるため、前記第1の仮想三次元モデル(6)における第1の仮想接触範囲(31)と前記第2の仮想三次元モデル(8)における第2の仮想接触範囲(32)との間で生じる差異が最小化され、前記検出された幾何学的な位置関係に基づいて、前記第1の仮想三次元モデル(6)及び/又は前記第2の仮想三次元モデル(8)が変形されるため、前記第1の仮想接触範囲(31)が前記第2の仮想接触範囲(32)に一致することを特徴とする、方法。
- 前記接触パターンの接触範囲(31、32)が、前記第1の仮想三次元モデル(6)と前記第2の仮想三次元モデル(8)との間の局所的な対応関係になることを特徴とする、請求項1に記載の方法。
- 前記第1の仮想三次元モデル(6)よりも高い測定精度を備える前記第2の仮想三次元モデル(8)が変更されずに維持され、前記第1の仮想三次元モデル(6)を前記第2の仮想三次元モデル(8)に適合させるために前記第1の仮想三次元モデル(6)が変形されることを特徴とする、請求項1に記載の方法。
- 前記第2の仮想三次元モデル(8)よりも高い測定精度を備える前記第1の仮想三次元モデル(6)が変更されずに維持され、前記第2の仮想三次元モデル(8)を前記第1の仮想三次元モデル(6)に適合させるために前記第2の仮想三次元モデル(8)が変形されることを特徴とする、請求項1に記載の方法。
- 前記第1の仮想三次元モデル(6)及び前記第2の仮想三次元モデル(8)を形成するための個々の撮像の記録が、包括的な記録を用いて行われ、記録エラーを低減するために、記録する撮像のそれぞれが、前回の撮像及びすでに実施されたもう1つの撮像と共に記録され、前記記録する撮像、前記前回の撮像及び前記もう1つの撮像が共通の重なり範囲を備えていることを特徴とする、請求項1乃至4のいずれか1項に記載の方法。
