Abstract
Systems and methods for fabricating indirect bonding trays are disclosed. Physical models of a patient's teeth can be created with non-functional placeholder brackets, impressions of which can be transferred to indirect bonding trays. This can create wells in which functional brackets can be placed into, reducing errors created from transferring functional brackets from the physical model onto the indirect bonding trays.
Claims10
A method of fabricating an indirect bonding tray, the method comprising:
- providing a digital model of a patient's teeth in positions of malocclusion;
- digitally moving the patient's teeth from the positions of malocclusion to positions of ideal occlusion in the digital model;
- digitally positioning digital brackets on respective lingual surfaces of the patient's teeth while in the positions of ideal occlusion in the digital model;
- digitally restoring the patient's teeth from the positions of ideal occlusion to the positions of malocclusion while maintaining the positioning of the digital brackets on the respective lingual surfaces of the patient's teeth in the digital model;
- digitally indicating locations for perforations between adjacent teeth of the patient in the digital model, the perforations configured to be used to create a sectional indirect bonding (IDB) tray corresponding to a segment of the patient's dental arch;
- modifying the digital brackets to reduce internal features;
- creating a physical indirect bonding (IDB) tray, the IDB tray comprising perforations corresponding to the digitally indicated locations for perforations, indicia with printed instructional information, and wells, each of the wells corresponding to an external geometry and positioning of a corresponding one of the modified digital brackets in the digital model with the patient's teeth restored to the positions of malocclusion, the wells configured to receive brackets to be bonded on the patient's teeth, and the printed instructional information comprising one or more color markers configured to visually assist in properly placing the IDB tray on the patient's teeth, patient identification information, an upper or a lower arch indicator, and tooth number positions;
- loading the wells of the IDB tray with brackets;
- and
- sending the IDB tray with the wells loaded with brackets to an orthodontic office.
