Aim: To assess the effectiveness of zygomatic anchorage for the intrusion of maxillary posterior teeth. Method: A male patient, 20 years 5 months of age, with 3-mm anterior open bite with excessive maxillary posterior growth, was accepted for treatment. Titanium miniplates were fixed bilaterally to the zygomatic buttress area and 200 g of force was applied unilaterally with 9-mm nickel-titanium coil springs between the vertical extension of the miniplate and the first molar buccal tube. Later, the zygomatic site was used for maxillary canine distalization. Results: The maxillary posterior teeth were intruded effectively and the canines were distalized bodily, without anchorage loss, with the help of zygomatic anchorage. The patient was advised to maintain good oral hygiene throughout the treatment. This noninvasive surgical procedure eased and reduced the operation time and did not require headgear wear nor anterior box elastics for anterior open bite correction. Conclusion: The zygomatic area was found to be a useful anchorage site for the intrusion of the molars over a short period of time. Long-term stability of the bite closure should be assessed in future studies. World J Orthod 2002;3:147153.
