Introduction: The treatment for patients with mild skeletal maxillary excess can be camouflaged by distalisation of the entire maxillary arch. This study compares the efficacy
of aligners and passive self-ligation appliance to achieve en masse maxillary arch distalisation using infrazygomatic crest miniscrews. Materials and methods: 12 patients indicated for distalisation with infrazygomatic crest miniscrews were selected. Group 1 (n=6) was bonded with passive self-ligation appliance. Group 2 (n=6) used clear aligners for treatment. Cephalometric software was used to compare the pre and post distalisation readings in the individual appliances for quantifying
the amount of distalisation. Results: Aligners demonstrated more retraction of the upper incisors. . Conclusion: Both the appliances are effective in en masse maxillary distalisation. Dental parameters demonstrated aligners having better control in distalisation. Keywords: Infra zygomatic crest screws, TAD, Self-ligation appliance, aligners.
