Abstract
【解決手段】弧線を受容するための溝を規定する壁部を有する胴体部と、近心端部、遠端部、歯肉端部及び咬合端部を有する無孔基部を含み前記胴体部を歯に結合するための前記胴体部に接続された結合構造体と、を含み、前記結合構造体が、第1の結合強度値で前記近心端部を前記歯に結合させるための第1の手段と第2の結合強度値で前記遠端部を前記歯に結合させるための第2の手段と第3の結合強度値で前記歯肉端部を前記歯に結合させるための第3の手段と第4の結合強度値で前記咬合端部を前記歯に結合させるための第4の手段とを含み、前記第1の結合強度値、前記第2の結合強度値及び前記第3の結合強度値の少くとも1つが前記第4の結合強度値より小さいことを特徴とする歯科矯正具を提供する。
【選択図】図1
Description
しかしながら、結合構造体19bは、基部20bに結合し、器具10bの胴体部から離れる方向において外側に広がる一連の突起物36bを含む。突起物36bは、接着剤がいったん硬化すると機械的に組み合うようにハンマーの頭様のマッシュルーム形の頭部のような大きな頭部を任意に有する。図6に示される突起物36bは正方形の断面形状であるが、円柱又は方形の形状の突起物のような他の形の突起物も用いることができる点も理解されるはずである。他のものとして、突起物36bは、先に記載の粒子32,32aのような規則的又は不規則的な形状の粒子をすることもできる。
任意的に、器具10cの胴体部及び基部20cは、ステンレススチールのような金属から作られ、メッシュパッド38cもステンレススチールから作られる。メッシュパッド38cは、溶接又はろう付け作業により基部20cに付着される。適切なメッシュパッドの例は、3M Unitek Corporationから得られる“DYNABOND”ブランドの結合基部を含む。
あるいは、部分22d,24dは基部20dに対する歯科矯正用接着剤の結合強度を削減する材料で被覆することができる。このような例において、材料48dは必要に応じて除去するか、又は先に記載の方法において用いることができる。
材料48eは、基部20eに対する矯正歯科用接着剤の結合強度を増強するための基部20e上に被覆される。材料48eは、先に記載される材料48dと同一にすることができる。しかしながら、本例において、材料48eは、部分26eより大きい部分22e,24e及び28eの表面領域を覆う。結果として、歯に対する器具10eの結合強度は、部分22e,24e及び28e下の領域より部分26e下の領域においてより小さい。
