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 method and apparatus is provided for digitally checking the insertion quality of a target customized virtual arch wire designed during treatment planning prior to actually manufacturing the target arch wire. The method includes the steps of digitally simulating the insertion of the customized target virtual arch wire into the virtual brackets placed up on virtual teeth of a patient in an initial state of interest for checking if the arch wire could be inserted into the virtual brackets without conflicts or collisions. The initial state may be a malocclusion state or any intermediate treatment state of the patient. In the event the target virtual arch wire would cause conflicts, then the simulation optimizes the arch wire design in an attempt to eliminate the conflicts. In another aspect, a method is provided for selecting the recommended starting point for inserting the customized arch wire in the brackets placed on the dentition of the patient in the initial state.

A dental occlusion correcting system (DOCS) that is designed to simplify and expedite the correction of Class II dental malocclusions. The DOCS (10) includes a set of upper and lower molar attachment structures (13,14), attached respectively to a person's upper molar and lower molar, a set of upper and lower loosely attached linkages (11,12), and a force module (70). Each of the loosely attached linkages (11,12) includes a link pivitor (50) and a link base (30) which are rotatably connected together through a system of gears and stops and rotational sections (43,44,58,59). The upper and lower loosely attached linkages are connected together, on the same side of a patient's dentition, by a force module. The force module produces upward-backward and downward-forward compression force, commensurate with the force required by a specific dental patient.

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.
