Objective: To use a biomimetic appliance prior to the use of removable clear aligners to reduce the necessity for interproximal reduction in the correction of malocclusions. Subjects: Three adult females aged 23-38yrs. Subject A had a narrow upper arch and mandibular retrognathia; Subject B had crowding and an increased overjet; Subject C had anterior and posterior crossbite. Intervention: All subjects were given optional treatment plans of DNA appliance therapy followed by Invisalign to improve the occlusion. Results: Subject A showed improved mandibular positioning, with improved facial soft tissues. Subject B showed improved posterior occlusion with an increase in upper and lower arch width, resulting in improved facial soft tissues and smile esthetics. Subject C showed improved posterior occlusion, correction of the anterior crossbite and a corrected midline. Conclusions: All three subjects that complied with a non-fixed, DNA appliance/Invisalign protocol showed functional and cosmetic improvements in occlusion without any interproximal reduction.
