摘要： A dental impression tray assembly includes an impression tray as well as a liner. The liner is adapted to cover holes in the impression tray in order to prevent leakage of impression material through the holes during a dental procedure. Preferably, the liner is removably connected to the tray so that the practitioner has the option of using the tray with or without the liner.

摘要： A bite opener for use during orthodontic treatment has a base for mounting on a lingual side of a tooth, as well as at least one occlusal portion for contact with an opposing tooth so that other teeth (such as molar teeth) can be extruded. In one embodiment, the bite opener has a channel extending between a mesial section and a distal section, so that the sections can be squeezed together when desired to debond the bite opener from the patient's tooth. In other embodiments, the bite opener includes a bite plate connected to the body, and the bite plate is made of a material softer than the body to enhance patient comfort when the jaws are closed. Optionally, the bite plate is detachably connected to the body so that the bite plate can be removed before debonding the body from the tooth.

摘要： An attachment device useful during the course of orthodontic treatment couples an interarch appliance to brackets and/or to archwires placed in the oral cavity. The attachment device includes a wire segment that crosses over a labial side of an archwire in order to enable a coupler of the interarch appliance to slide past the archwire as the patient's jaws are opened. The attachment device increases the range of free sliding motion of the interarch appliance and reduces the amount of stress that might be otherwise imposed on the appliance, on the brackets and/or the archwires as the patient's jaws are opened. The attachment device is particularly suitable for use with Class II correction appliances including elongated, resilient force modules that have an inherent bias toward a normally straight orientation.
摘要翻译： 在矫正治疗过程中有用的附件装置将置放器置于支架和/或放置在口腔内的弓丝上。 附接装置包括穿过弓丝的阴唇侧的线段，以便当病人的钳口被打开时能够让家庭装置的耦合器滑过弓丝。 附接装置增加了行星器具的自由滑动运动的范围，并且减小了当患者的钳口打开时可能施加在器具上，支架和/或弓线上的应力的量。 附件装置特别适用于II类校正装置，包括细长弹性力模块，其具有朝向正常直线定向的固有偏压。

摘要： A method and apparatus for curing photocurable dental materials involve a solid state light emitter and a source of electrical current connected to the light emitter. The source of electrical current provides a current to the light emitter that is sufficient to reduce the lifetime of the light emitter to less than 10 hours. The intensity of light from the light emitter is substantially increased and the apparatus can be conveniently disposed of after use on a single patient. A light guide that includes two conical optical surfaces collects light from the solid state light emitter and optionally directs the light to a third optical surface which has the shape of an elongated, curved tube.
