Description
本発明は、一般に、矯正歯科の分野に関し、そしてより詳細には、徐々に歯を再配置するためのシステムおよび方法に関する。
本発明は、歯のコンピューターモデルを配列するためのシステム、装置およびコンピューター実行可能な方法を包含する。
上記歯列弓形が歯の付着点を通るように、各歯を配置する工程を包含する。
図1は、上顎骨22および下顎骨20とともに頭蓋10を示す。下顎骨20は、頭蓋10に対して関節30で蝶番式につながっている。関節30は、側頭下顎骨関節(TMJ)とよばれる。上顎骨22は、上顎101と関連づけられている一方で、下顎骨20は、下顎100と関連づけられている。
たは回転方向のいずれかに動くにつれて、累積平行移動を受ける。すなわち、この点は通常非線形経路をたどるが、処置の間のいずれか2回、決定されるときに、歯の任意の点の間に線形距離が存在する。従って、任意の点P1は、事実、矢印d1により示されるように、真の側方から側方への平行移動を受け得るが、第2の任意の点P2は、弓状経路に沿っ
て移動して、最終的な平行移動d2を獲得し得る。本発明の多くの局面は、任意の特定の
歯に対して示された点P1の最大の許容可能な移動に関して規定される。このような最大
の歯の移動は、次いで、任意の処置工程においてその歯のための最大の移動を受ける歯上の点P1の最大線形平行移動として規定される。
1.上顎の永久第一臼歯の近心面頬面の咬頭が、下顎の永久第一臼歯の近心の咬頭と中心の頬側の咬頭との間の溝に咬合する。
2.上顎の第一臼歯の遠心の辺縁隆線が、下顎の第二臼歯の近心の辺縁隆線と咬合する。
3.上顎の第一臼歯の近心面舌面の咬頭が、下顎の第一臼歯の中心の窩と咬合する。
4.上顎の小臼歯の頬側の咬頭が、下顎の小臼歯との咬頭鼓形空隙関係を有する。
5.上顎の小臼歯の舌側の咬頭が、下顎の小臼歯と咬頭窩関係を有する。
6.上顎の犬歯が、下顎の犬歯および第一小臼歯と咬頭鼓形空隙関係を有する。この咬頭の先端は、鼓形空隙に対してわずかに近心である。
7.上顎の切歯が、下顎の切歯と重なり、そして弓の中線が一致する。
1.大部分の上顎の切歯が、正の傾斜を有する;下顎の切歯が、わずかに負の傾斜を有する。大部分の最適なサンプルにおいて、切端間の歯冠角度は、180°未満である。上顎の切歯の歯冠は、下顎の切歯が咬合平面に対して90°の線に対して負に傾斜するより、この線に対してより正に傾斜する。
2.上顎の切歯歯冠の傾斜が、ほぼ正である(中心が側方より正である)。犬歯および小臼歯は、負であり、そして非常に類似している。上顎の第一および第二の臼歯の傾斜もまた、類似しており、そして負であるが、犬歯および小臼歯の傾斜よりわずかにさらに負である。臼歯はより負である。なぜなら、これらは、犬歯および小臼歯が測定される隆起した顔側の縁部からではなく、溝から測定されるからである。
3.下顎の歯冠の傾斜が、切歯から第二臼歯にかけて、前進的により負である。
