A method comprising: gathering a first digital model representing a dental arch-like structure of a patient, wherein the dental arch-like structure comprises one or more tooth-like structures to interface with a polymeric aligner; gathering a second digital model representing the polymeric aligner to be supported by the dental arch-like structure, wherein the polymeric aligner comprises one or more tooth-receiving cavities to receive the one or more tooth-like structures of the dental arch-like structure, and wherein the second digital model specifies first one or more physical properties of the polymeric aligner at one or more regions of the polymeric aligner; simulating an interaction of the polymeric aligner to the dental arch-like structure using the first digital model and the second digital model; simulating a removal of the polymeric aligner from the dental arch-like structure using the first digital model and the second digital model to obtain a simulated removal of the polymeric aligner from the dental arch-like structure; determining a likeliness that one or more values at the one or more regions will satisfy one or more damage criteria, the determination being based on an interaction of the dental arch-like structure and the first one or more physical properties of the polymeric aligner, and the interaction being due to the simulated removal; analyzing the second digital model for one or more likely points of physical damage based on the determination of the likeliness of the one or more values satisfying the one or more damage criteria; and in response to analyzing the second digital model for the one or more likely points of physical damage, determining whether to implement one or more corrective actions for the polymeric aligner. gathering a first digital model representing a dental arch-like structure of a patient, wherein the dental arch-like structure comprises one or more tooth-like structures to interface with a polymeric aligner; gathering a second digital model representing the polymeric aligner to be supported by the dental arch-like structure, wherein the polymeric aligner comprises one or more tooth-receiving cavities to receive the one or more tooth-like structures of the dental arch-like structure, and wherein the second digital model specifies first one or more physical properties of the polymeric aligner at one or more regions of the polymeric aligner; simulating an interaction of the polymeric aligner to the dental arch-like structure using the first digital model and the second digital model; simulating a removal of the polymeric aligner from the dental arch-like structure using the first digital model and the second digital model to obtain a simulated removal of the polymeric aligner from the dental arch-like structure; determining a likeliness that one or more values at the one or more regions will satisfy one or more damage criteria, the determination being based on an interaction of the dental arch-like structure and the first one or more physical properties of the polymeric aligner, and the interaction being due to the simulated removal; analyzing the second digital model for one or more likely points of physical damage based on the determination of the likeliness of the one or more values satisfying the one or more damage criteria; and in response to analyzing the second digital model for the one or more likely points of physical damage, determining whether to implement one or more corrective actions for the polymeric aligner. <EOS>
