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.
Claims13
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's teeth in the digital model;
- and
- 3D printing an IDB tray based on the digital model, the IDB tray corresponding to a partial segment of a dental arch of the patient and comprising perforations corresponding to the digitally indicated locations for the perforations to section the IDB tray, indicia with printed instructional information, and wells, each of the wells corresponding to an external geometry and positioning of a corresponding one of the 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 to the patient's teeth, and the printed instructional information comprising one or more color markers with an upper or a lower arch indicator, tooth numbers for each tooth of the partial segment of the dental arch, and patient identification information configured to visually assist in placing the IDB tray on the dental arch of the patient.
