Description
2.内分泌撹乱作用物質であるビスフェノールAの溶出がないため、人体に使用しても安全性が高い。
3.全ての添加剤に対して、この樹脂成分は口腔内での溶出がないため安全性が高く、また、添加剤、顔料についても安全面で心配はない(本発明の歯科用成形樹脂材料の融点は例えば180℃程度であるため)。
4.義歯床の審美的自然感を増すために、成形体中に人間の口腔内の血管を模した色に着色されたポリエステル繊維体が埋設されてもよい。
5.ステアリン酸マグネシウムを添加剤として配合することにより、樹脂染色時において顔料が全てにまんべんなく混ざり、染色性が非常に高まる。
6.ステアリン酸マグネシウムを配合することにより、樹脂自体の表面の滑沢度が増し、滑りが良くなるため、義歯床体の脱着に有効的である。
7.酸化チタン(酸化鉄)を添加剤として配合することにより、義歯床染色時において人体歯肉に合った自然観のある色合いを再現できる。
8.本発明の歯科用成形体によれば、従来から使用されている歯科用成形樹脂材料(ポリカーボネート、ポリエチレンテレフタレート(PET)、アクリル等)に比べ、機械的強度、曲げ強度、耐熱性に優れているため、義歯床の破折も生じにくく、かつ非常にコンパクトで口腔内での違和感のない義歯床製作が可能であり、吸水性も従来からの樹脂材料に比べ非常に低いため、吸水による雑菌の繁殖や樹脂物性劣化が極めて少ない。
9.さらに上述の組成の歯科用成形樹脂材料は、比重において他の樹脂よりも軽いため、例えば義歯床としての使用において口腔内組織への負担が少ない。
10.本発明の歯科成形樹脂材料は、従来の樹脂材料に比べ、空気中の水分を吸収しにくいため、常温での保管状態においても問題がなく、射出成形時においても水分を除去するために熱乾燥させる必要もなく、作業効率性においても優れている。
11.なお、本発明の歯科用成形樹脂材料はペレット状のものが一般的であるが、これに限定されるものではなく、シート状等のものであっても良い。
本発明の樹脂材料を、射出成形により20mm×20mm×3mmのサイズの板材に製作し調整し、沸騰水(約100℃)中に1時間浸漬し、成形体の外観を確認した結果、面荒れ白濁等は見られなかった。したがって本発明材料を使用し製造された義歯床、暫間被覆冠、歯科矯正器具、人工歯等においても同様の結果が得られる。

1b 人工歯
2 歯科矯正器具
3 人工歯
4 マウスピース(暫間被覆冠)
