摘要： A thermoformed plastic dental retainer and method of selectively straightening crooked or maloccluded teeth and retaining the straightened teeth using the retainer. The dental retainer is constructed by first forming an impression of a patient's upper or lower dentition and constructing a cast from the impression. The retainer is vacuum thermoformed over the cast using a sheet, plate or disc of thermoformable plastic and a vacuum or pressure thermoforming machine. A protrusion or divot is formed in the retainer on the labial or lingual side of each tooth which is to be repositioned lingually or labially, respectively, and a gap, opening or window is formed in the retainer on the opposite side of the divot to accommodate unhindered tooth repositioning movement. As the retainer is worn on the patient's dentition over a period of days or weeks, the projecting divots apply pressure to the respective teeth and push the teeth into the gap or window of the retainer to a straightened position. By appropriately positioning the divots in the retainer with respect to the patient's malpositioned teeth, the teeth may be moved libially, lingually or rotated, as needed, for straightening.
摘要翻译：一种热成型塑料牙科保持器和使用保持器选择性矫直弯曲或偏心的牙齿并保持矫直齿的方法。牙科保持器通过首先形成患者的上部或下部牙列的印模并且从印模构造铸件来构造。保持器使用可热成型塑料的片材，板或盘和真空或压力热成型机在铸件上真空热成型。在每个齿的唇形或舌侧上的保持器中分别形成突起或凹陷，该侧面将被分别在舌头或阴唇上重新定位，并且在护套的相对侧上形成间隙，开口或窗口以容纳不受阻碍的牙齿重新定位运动。由于保持器在几天或几周的时间内佩戴在患者的牙列上，所以突出的凸起对相应的牙齿施加压力，并将牙齿推进到保持器的间隙或窗口中以达到矫直位置。通过相对于患者的错误定位的齿适当地定位保持器中的凹部，根据需要可以根据需要使牙齿自由地，舌形地或旋转，以矫正。

摘要： A gasket for vacuum thermoforming machines, which gasket is designed to be positioned on the perforated base plate of the thermoforming machine to cover selected ones of the vacuum openings in the base plate. An opening is provided in the center of the gasket for concentrating the vacuum in this area and increasing the vacuum applied to a heated plastic sheet or plate positioned above a dental impression cast located on the base plate in the gasket vacuum opening. The vacuum applied by the vacuum thermoforming machine is thus concentrated within the confines of the vacuum opening of the gasket to more efficiently mold the soft plastic plate over the dental impression cast and form a plastic retainer for straightening teeth. A method for molding a plastic retainer for straightening teeth, which method includes the steps of placing a gasket having a vacuum opening over the perforated base plate of a vacuum thermoforming machine such that some of the vacuum openings are covered by the gasket and others are exposed in the vacuum opening in the gasket; positioning a plastic plate above the gasket adjacent to the heater in the vacuum thermoforming machine; placing a dental impression cast on the perforated base plate in the opening in the gasket; heating the plastic plate; initiating the vacuum in the perforations in the base plate defined by the opening in the gasket; and lowering the softened plastic plate over the dental impression. Additional, and/or oversized perforations may also be provided in the gasket vacuum opening to increase the vacuum applied to the plastic plate.

摘要： Low-density polyethylene dental whitening or bleaching trays are molded to a dental impression cast of a patient, typically by vacuum or pressure thermoforming techniques. In a typical application, a low-density polyethylene plate or sheet is molded on a dental impression cast by operation of a vacuum or pressure thermoforming machine to produce bleaching trays of high quality and extended use for whitening the teeth of patients. The low-density polyethylene material so molded has superior memory for repetitive clinging fit on the teeth and is comfortable and virtually transparent while in place.

摘要： A cleaning apparatus and method for cleaning dental and/or medical implements, and in particular to a system for quickly and thoroughly cleaning dental and/or orthodontic retainers, dental/orthodontic aligners, dental appliances, dentures, bridges, and the like. The preferred embodiment of the present invention contemplates a cleaning system utilizing a vibrating sonic wave bath comprising a vibration means to oscillate a container having at least some fluid therein engaging the item to be cleaned, coupled with the utilization of a preferably flavored tablet containing a non-toxic cleaning material, the tablet preferably also formulated to effervesce upon contact with water, generating bubbles and foam. It has been found that the sonic bath substantially enhances the cleaning and flavoring ability of the effervescent cleaning tablet, while reducing the amount of time to clean the dental appliance. The preferred embodiment of the present invention provides a relatively cost effective, safe, easy to use and reliable system for cleaning and flavoring dental appliances and the like.

摘要： A novel system for discerning pressure points in mouthpieces, namely orthodontic aligners. The system includes the steps of applying a colored gel to a light transmissive or clear mouthpiece-type aligner, mounting the aligner to the upper and/or lower teeth of the patient, and observing through the mouthpiece color variations generated by variations in gel density, wherein pressure points are indicated as lighter colors due to less gel density and spaces are indicated as deeper color, due to higher density of the colored gel. In an alternative embodiment a second gel incorporating rupturable spheres incorporating a second composition is utilized in the present system such that pressure upon the gel releases the second composition, which would be formulated to combine with the first gel and result in a color change, either due to a chemical reaction, or due to a mixing of two colors to produce an identifying color.
摘要翻译：一种用于识别口腔中压力点的新颖系统，即正畸矫正器。该系统包括以下步骤：将有色凝胶施加到透光或透明的喉舌型对准器上，将对准器安装到患者的上部和/或下部的牙齿上，并通过口部观察通过凝胶密度变化产生的颜色变化，其中压力点由于较少的凝胶密度而被指示为较浅的颜色，并且由于着色凝胶的较高密度，空间被指示为更深的颜色。在另一个实施方案中，在本系统中使用结合有第二组合物的可破裂球体的第二凝胶，使得凝胶上的压力释放第二组合物，其将被配制成与第一凝胶结合并导致颜色变化，化学反应，或由于两种颜色的混合产生识别颜色。

摘要： A glow-in-the-dark plastic dental appliance typically for pediatric dental patients, and method of constructing the appliance. According to a preferred method of the invention, the dental appliance is constructed by first forming an impression of a patient's upper or lower dentition and constructing a cast from the impression. The appliance is thermoformed over the cast, typically using a vacuum or pressure thermoforming machine and a sheet, plate or disc of thermoformable plastic impregnated or coated with a phosphorescent material. The appliance is capable of glowing in the dark for a limited period of time after exposure to a light source and as the appliance is worn on the patient's dentition, and is capable of repeated phosphorescence throughout the dental treatment period.

摘要： A thermoformed plastic dental retainer and method of construction including rapid cooling of the retainer, typically using a refrigerant coolant, as the retainer sets on a dental impression cast. The dental retainer is constructed by first forming an impression of a patient's upper or lower dentition and constructing the cast from the impression The retainer is vacuum-thermoformed over the cast using a sheet, plate or disc of thermoformable plastic and a vacuum or pressure thermoforming machine. As the thermoformed plastic retainer sets on the cast, the retainer is rapidly cooled typically by spraying a refrigerant coolant on the retainer. This step causes the retainer to thermally contract against and precisely conform to the configuration and texture of the cast for an accurate and tight fit of the retainer on the patient's dentition Protrusions or divots may be formed in the retainer to apply repositioning pressure to maloccluded or crooked teeth while the retainer is worn on the patient's dentition over a period of days or weeks.
