Abstract: An orthodontic appliance system for orthodontic treatment of teeth. The system includes a template with a cavity. An attachment is removably received in the receptacle and has a surface including a bonding surface. A method of manufacturing includes constructing a scaffold assembly including a base and placing a template in contact with the scaffold assembly. The method includes inserting the attachment into the receptacle. During separating, the attachment remains coupled to the template in the receptacle. A method of manufacturing includes providing a mold of the patient's teeth. The mold including at least one projection and a through-passage. The method includes placing a container of dental composite in fluid communication with the through-passage, placing a template over the at least one projection, injecting dental composite from the container through the through-passage and into the receptacle, and removing the template from the at least one projection with the filled receptacle.

Abstract: An aligner including a feature positioned on or in at least one of the buccal sidewall or lingual sidewall of the aligner that is configured to attach to an elastic member. The aligner applies a greater corrective force to a patient's dentition when the elastic member is attached. The feature may include a protrusion in the sidewall with an opening to a space configured to receive and attach to an elastic member hook coupled to the elastic member. The feature may include a through-bore in the sidewall that is configured to receive and attach to the elastic member. The feature may include an add-on hook on the sidewall that is configured to receive and attach to the elastic member. The add-on hook may be positioned on a protrusion in the sidewall. The protrusion may receive and engage with a dental attachment positioned on a surface of a patient's tooth.
