Lower Molar Distalization Using Clear Aligners: Bodily Movement or Uprighting? A Preliminary Study

Background: Lower molar distalization is considered to be one of the most difficult movements obtain with clear aligners. The aim this study was evaluate possibility distalize lower molars using aligners in adults without miniscrews. Material and methods: rx cephalograms 16 patients (8 males, 8 females; mean age 25.6 years), who underwent distalization, were analyzed. Cephalograms taken before beginning treatment (T0) after end (T1). Dental skeletal changes between T0 T1 evaluated. level significance set at p < 0.05. Results: At T1, second moved distally 2.47 mm, but there a significant tipping (p = 0.027); same result found first molar, distal movement 1.16 mm 0.003). No detected on sagittal vertical variables. Conclusion: Clear aligner therapy can provide more than bodily when programmed. This could sufficient correct initial malocclusion gain class I relationship.
