A method and apparatus for facilitating placement and evaluation of virtual appliances on virtual teeth of an orthodontic patient are described. Positioning references comprising bracket height, occlusal plane, or any arbitrary plane are provided to facilitate desired placement of virtual appliances on virtual teeth model. The process can be applied with any dentition state of a patient such as malocclusion, target state from treatment, or intermediate monitored state during the course of a treatment. An unified workstation for treatment planning provides the computer software tools for verification, simulation and evaluation of the virtual appliance placement. The process enables proper planning of treatment for an orthodontic patient suffering from malocclusion involving bonding of virtual brackets to the surface of the patient's virtual teeth with archwires placed in the slots of the brackets, so as to realize the desired results from the treatment in the most desired manner.

It is a common practice with orthodontists in planning treatment for a patient to prescribe dental changes to cure the malocclusion condition of the patient in terms of mesial or distal, buccal or lingual, and occlusal (coronal) or gingival translational displacements; and facial or lingual torque; mesial or distal angulation and mesial or distal rotation displacements. A method and workstation for measuring the dental displacements, or conversely placing the dental elements in desired positions as per the prescriptions for their displacements in a consistent, reproducible and accurate manner is disclosed. A novel orthogonal curvilinear coordinate system is disclosed that enables the measurement of the tooth displacements in conjunction with the individual tooth axes system.

A dental appliance having increased or decreased thickness between an upper shell and a lower shell in combination with a hinging mechanism and a system and a method for treating malocclusions are provided. The dental appliance may have an upper shell and a lower shell which receive upper teeth and lower teeth, respectively, of a user. The upper shell and the lower shell may be attached at a hinge. The dental appliance may have an increased thickness between the upper shell and the lower shell as well as an increased thickness of the hinge. In an embodiment, the dental appliance may have a decreased vertical thickness and an insertable hinging mechanism. The dental appliance may then extend treatment of malocclusions to the rear teeth of the user and may correct a dental condition, such as, for example, overbite, overjet, open bite, crowding, rotations, spacing, cross-bites, gummy smiles and temporomandibular joint problems.

Methods and systems are provided for manufacturing an appliance for correcting malocclusions of a patient's teeth. The method may include measuring the positions of a patient's teeth and receiving tooth movement constraints. The method may also include generating an initial treatment plan based on the measured tooth positions and the tooth movement constraints and measuring the malocclusions of the patient's teeth for one or more types of dental malocclusions. The method may also include generating a plurality of treatment plans from the initial treatment plan based on the measured malocclusion and generating a model of an appliance for each stage of the treatment plan. The method may also include generating instructions for fabricating the appliance for each stage of the treatment plan based on the model of the appliance for each stage of the treatment plan.

A system and method for simultaneously (i) treating a patient's malocclusion by repositioning teeth from an initial tooth arrangement to a final tooth arrangement and (ii) treating Obstructive Sleep Apnea (“OSA”) by forcing the mandible forward comprises a plurality of (e.g., 10-30) sets of individual appliances. The appliances are configured to be placed successively on the patient's upper and lower dental arches and to incrementally reposition the teeth and forcing the jaw forward, during sleep. The system of appliances is preferably configured at the outset of treatment so that the patient may progress through treatment without the need to have the treating professional perform each successive step in the procedure.

A ceramic orthodontic bracket has a centrally located clip for retaining an archwire in an archwire slot. The body of the bracket includes a mesial section, a distal section, and a bridge section, wherein the bridge section extends through, and retains, the clip. The bridge section also includes a recess adjacent to the bridge section that facilitates debonding of the bracket from a patient's tooth. Preferably there are gaps on one or both sides of the clip to allow space for debonding of the bracket by applying a mesial-distal compressive force on the bracket and fracturing the bracket along the recess. This configuration allows the overall mesial-distal width of the bracket to be reduced, thereby facilitating the bonding of brackets to narrow and/or maloccluded teeth. Another embodiment includes a stop member that is connected to the base of the bracket and retains the clip on the bridge section.

A method for treating malocclusion by installing an orthodontic apparatus on a patient configured to treat malocclusion, and applying shock waves to one or both temporomandibular joint (TMJ) of the patient. The application of the shock waves in combination with the force exerted on the mandible by the orthodontic apparatus results in accentuated and accelerated corrective growth and adaptation of the mandible.
