摘要： The present invention provides methods and systems of repositioning teeth for use in orthodontic treatment, with particular applicability to removable elastic repositioning appliances. Such appliances may be challenged by traditional tooth movements which intrude the crown of the tooth or present tooth positions which reduce available points of purchase. These challenges may be overcome with a series of tooth movements in which a tooth is translated in a “root-first” position. The movements may take advantage of the inherent characteristics of elastic repositioning appliances in translating a tooth from a first position to a desired position along a gingival plane.

摘要： The present invention provides a manipulable or reconfigurable dental model system and methods for its use to model a series of tooth configurations corresponding to sequential tooth movements during an orthodontic treatment. When a patient undergoes orthodontic treatment, teeth and bite configurations are realigned in a series of stages. Each stage represents a new pattern or dental configuration that will eventually lead to a proper final positioning of the entire dentition. Progress from the initial configuration, through the intermediate stages and finally to the final configuration may be accomplished using any one or a combination of different dental appliances. Of particular interest to the present invention, many of these appliances may be made using a dental mold representing the patient's dental configuration. In particular, thermoformable plastic positioning appliances which fit over the patient's teeth may be formed over a three-dimensional mold of the patient's dentition. When successive appliances are used throughout treatment to reposition the teeth from initial to final configuration, a new mold has typically been produced to fabricate the appliance for each stage. The present invention provides an apparatus and methods which employ a manipulable or reconfigurable mold to model patient dentition and gingiva at each stage of treatment.

摘要： Traditional orthodontic treatment often involves the use of basic repositioning devices, such as braces, and the use of supplementary devices, components or accessories to achieve desired end results. Such components may be mounted on fixed, non-removable devices or they may be part of a removable appliance typically worn prior to the application of the fixed devices. As with traditional treatment, it may be desired to utilize similar components when repositioning teeth with removable elastic repositioning appliances. Due to the nature of elastic appliances, such components may take a variety of forms ranging from readily available traditional accessories to specially created devices. Thus, traditional components may be mounted on or embedded in an elastic appliance, or the appliance may be formed to provide similar components. Likewise, the appliance may be modified to provide additional features for specific orthodontic treatments.

摘要： An improved dental appliance system, and methods for using and fabricating the improved appliance, including a polymeric overlay or shell having a teeth-receiving cavity formed therein. The dental appliance having the necessary stiffness or strength to firmly secure the appliance on the teeth and provide controlled forces required for repositioning the teeth, until such time as removal of the appliance is desired. The appliance may be configured for use with a removal mechanism. The removal mechanism provides for selective release of the appliance from the teeth as the removal mechanism undergoes a state change stimulated by an environmental stimulus or environmental switch.

摘要： Practitioners are certified to perform a medical procedure, such as an orthodontic procedure. Certified practitioners are maintained in a referral directory and classified within tiers based on criteria such as the number of procedures that they have performed. Inquiries are solicited from prospective patients, and referral lists are provided to those patients who request them. The referral lists are obtained from the referral directory with doctors from higher tiers who have performed more procedures receiving preferential inclusion on the referral lists.
