摘要： Methods of making a removable dental positioning appliance include forming a sheet of transparent crystalline polymeric material into a shell having cavities shaped to receive and reposition teeth from a first orientation to a successive orientation. The polymeric material may then be annealed at a temperature above its glass transition temperature or cured if a curable material to enhance characteristics of the polymeric material. The polymeric material may be coated with a second transparent material.

摘要： Apparatus for cleaning removable oral appliances, such as tooth repositioning aligners, comprise a base having a tray for holding the appliance in a bath of cleaning solution. A low-frequency driver is provided in the base for reciprocating the tray about a horizontal or vertical axis to wash the cleaning solution over the appliance. Usually, the apparatus will further comprise a cradle which is mounted to reciprocate about a horizontal axis within the base. The cradle defines a receptacle which removably receives the cleaning tray. The cleaning tray is preferably reciprocated at frequency in the range from 1 Hz to 10 Hz, usually in the range from 2 Hz to 5 Hz.

摘要： Dental floss brushes, as described herein, are extremely difficult to coat with wax coatings. When conventional waxes are utilized, the floss brush becomes matted and gummy. We have developed an improved wax coating solution which results in a thin, uniform coating with good adhesion characteristics. This invention relates to an improved floss brash product and to a novel process for its manufacture. In particular this invention is directed to an improved floss brash made of a textured, high tenacity nylon yarn which provides the scraping functions of a floss under high tension and the brushing functions of a yarn under low tension. The present yarns require a wax coating to improve lubricity during use. The present product exhibits a uniform, thin wax coating. The present process imparts a thin coating by utilizing a "viscosity lowering agent" in the wax coating solution.
摘要翻译： 如本文所述的牙线刷很难用蜡涂层涂覆。 当使用传统的蜡时，牙线刷变得无光泽和粘性。 我们开发出了一种改进的蜡涂层溶液，其导致薄且均匀的涂层，具有良好的粘附特性。 本发明涉及一种改进的牙线刷新产品及其制造方法。 特别地，本发明涉及一种由纹理化，高韧性尼龙纱线制成的改进的牙线刷，其在高张力下提供牙线的刮擦功能，并且在低张力下提供纱线的刷涂功能。 本纱线需要蜡涂层以改善使用过程中的润滑性。 本产品表现出均匀的薄蜡涂层。 本发明通过在蜡涂层溶液中利用“降粘剂”赋予薄涂层。
