A Prospective Multicenter Clinical Investigation Evaluating the Accuracy of the Trimline Design When Treated With SureSmile® Aligners.

Inclusion Criteria: * Subject willing to participate in the clinical investigation, able to understand the intent risks and benefits of the clinical investigation as well as associated time commitment and follow-ups visits. * Subject has signed and dated the informed consent form (ICF) . * Subject aged 18 years or above at time of informed consent. * Subject has permanent dentition (i.e., all 2nd molars). * Subject with a dental malocclusion, consistent with Levels 1 and 2 case complexity and within the clinical references as defined in the SureSmile Case Selection Guide. * Crowding or spacing must be ≤6mm present in one or both arches consistent with level 1 and 2 of case complexity. * Midline deviation must be ≤3 mm consistent with level 1 and 2 of case complexity. * Overjet must be ≤4 mm consistent with level 1 and 2 case complexity. * Overbite must be ≤3 mm consistent with level 1 and 2 case complexity. * Anterior open bite must be ≤1 mm, consistent with level 1 and 2 case complexity. * Intermaxillary elastics may be included within the treatment plan to support sagittal, vertical, or transverse correction within the limits defined under exclusion criteria. Exclusion Criteria: * Subjects unlikely to comply with investigational procedures, or unlikely to come back for follow-up visits, as judged by the Investigator. * Subject that presents a dental malocclusion classified as level 3 case complexity, as defined in the SureSmile Case Selection Guide. * Subjects…
