  • Patent number: 8326647
    Abstract: 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.

  • Publication number: 20120244488
    Abstract: A computer is used to create a plan for repositioning an orthodontic patient's teeth. The computer receives an initial digital data set representing the patient's teeth at their initial positions and a final digital data set representing the teeth at their final positions. The computer then uses the data sets to generate treatment paths along which the teeth will move from the initial positions to the final positions.

  • Patent number: 8235713
    Abstract: The present invention provides improved devices, systems and methods for repositioning teeth from an initial tooth arrangement to a final tooth arrangement. Repositioning is accomplished with a system comprising a series of polymeric shell appliances configured to receive the teeth and incrementally reposition individual teeth in a series of successive steps. The individual appliances may be formed from layers having different stiffnesses (elastic moduluses), and the stiffnesses of successive appliances may be different, or both.

  • Patent number: 7874837
    Abstract: Methods and corresponding apparatus for segmenting an orthodontic treatment path into clinically appropriate substeps for repositioning the teeth of a patient include providing a digital finite element model of the shape and material of each of a sequence of appliances to be applied to a patient; providing a digital finite element model of the teeth and related mouth tissue of the patient; computing the actual effect of the appliances on the teeth by analyzing the finite elements models computationally; and evaluating the effect against clinical constraints. The appliances can be braces, polymeric shells, or other forms of orthodontic appliance.

  • Publication number: 20090292556
    Abstract: 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.

  • Patent number: 7578674
    Abstract: Appliances are made using a dental mold representing a 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. An apparatus and methods which employ a manipulable or reconfigurable mold to model patient dentition and gingiva at each stage of treatment. The apparatus and methods are particularly useful for performing midcourse corrections during orthodontic procedures using a plurality of such appliances in sequence.

  • Publication number: 20080206701
    Abstract: 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.
