Abstract
A plastic shell such as an orthodontic aligner has an interior shape that substantially conforms to a current or future dental arch of a patient. The plastic shell includes a hollow feature comprising a cavity. The plastic shell additionally includes an object inserted into the cavity, wherein the object provides structural strength to the plastic shell at a location of the hollow feature and does not interfere with a fit of the plastic shell onto the dental arch of the patient.
