Systems and methods for fabricating indirect bonding trays are disclosed. Digital models of a patient's teeth can be created with digital brackets positioned on the digital model of a patient's teeth. Digital models of indirect bonding trays can be created to retain and transfer the brackets. The indirect bonding trays can be 3-D printed with wells that the functional brackets can be placed into and thereafter transferred to the patient. The 3-D printed indirect bonding tray can comprise two resins, with one resin forming the tray and another resin forming a functional feature.

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.

Non-sliding orthodontic appliances may include an archwire having male fasteners for locking in place with brackets in a non-sliding manner and interproximal loops for exerting forces on the brackets. Appropriate forces may be calculated according to vectors between initial and ideal tooth positions. The brackets may be transferred to a patient's teeth using indirect bonding trays which contain slots for holding and aligning each bracket. The trays may include integrated handles for facilitating handling, may be sectioned into smaller pieces for easier application, and/or may be labeled for facilitating proper registration. Superposition of a digital placement plan and clinical model after bonding may illustrate the accuracy of bracket placement. The archwire may comprise atraumatic ends to avoid patient discomfort. A color registration system can be used to facilitate the attachment of the archwire to the brackets. The archwire may be locked into place with the brackets using crimpable stops.

Hybrid orthodontic archwire designs are disclosed. Hybrid archwires may have bracket-archwire sections and interproximal archwire sections in which each section can vary in cross-section shape, size, and/or material properties. Bracket-archwire sections may be configured to promote torque control and may have rectangular cross-sections. Interproximal archwire sections may be configured to be bent into force-promoting loops and may have round cross sections. Each archwire section may be straight or bent into any shape. Hybrid archwires may have sliding sections and non-sliding sections. Non-sliding sections may have male connectors configured to prevent the archwire from sliding relative to the orthodontic brackets and/or may have cross-sectional shapes, sizes, or coatings that resist sliding relative to sliding sections. Sliding sections may have linear archwire segments. Hybrid archwires may have distal or posterior non-sliding sections and an intermediate anterior or medial sliding section.
