Abstract
Description
狭い範囲の医療用プラスチックは、発展してきた、主要な「強靭な」プラスチックの一部の使用を排除する。むしろ、本発明者等は、現行の医療等級プラスチックをより許容可能にすることを提案する。
1.エリアが薄くなると厚さがより均一になるようにモデル上で伸張するエリアの厚さを変えること。
2.厚さが均一のプラスチックを作製するが、平坦シートより薄くならないように伸張することになるエリアの一部に、部分的に構築される3Dエリアを事前成形すること。
3.ほぼ均一に成形した後に、平均引っ張り力が厚さを維持するように両方を行うこと。
本発明は、3つの解決策を提供する。
1.エリアが薄くなると厚さがより均一になるようにモデル上で伸張するエリアの厚さを変えること。
2.厚さが均一のプラスチックを作製するが、平坦シートより薄くならないように伸張することになるエリアの一部に、部分的に構築される3Dエリアを事前成形すること。
3.ほぼ均一に成形した後に、平均引っ張り力が厚さを維持するように両方を行うこと。
本出願は、失敗した処置についての不快さを制限し、医師および技工所に対するコストを低減し、関係するすべての人のためによりよい結果および繁栄を促進する。
Claims (6)
- 熱成形中のスランピングを補償するために、異なる厚さの少なくとも2つのエリアを有するシートを備える歯科デバイスの熱成形のためのプラスチック・シートであって、シートの少なくとも1つのエリアは、少なくとも1つの他のエリアより弾性がある歯科デバイスの熱成形のためのプラスチック・シート。
- 事前成形された歯列構造を備える歯科デバイスの熱成形のためのプラスチック・シート。
- 全体が均一な厚さを有する請求項3に記載のプラスチック・シート。
- ポリスチレンを含む請求項4に記載のプラスチック・シート。
- 熱成形後に80%を超えて半透明である請求項5に記載のプラスチック・シート。
- モデル上で熱成形するためのプラスチック・シートであって、プラスチックが前記モデル上で伸張するところでは厚く、また、成形中に弱くなるエリアが25%未満で伸張するような3Dプロトタイプで成形されるシートを備えるモデル上で熱成形するためのプラスチック・シート。
