Clinical Evaluation of a Direct Method for the Intrusion of Supraerupted Maxillary Molars: A Preliminary Study

Purpose: This study aimed to evaluate the use of orthodontic mini-implants for the intrusion of supraerupted maxillary molars. Materials and Methods: Nine patients were treated using buttons bonded on dental surfaces and mini-implants inserted on the buccal and palatal sides. The intrusion was evaluated by comparing radiographs obtained at the start of treatment and at the end of intrusion. The t test was used to compare the teeth positions. Results: There was statistically significant intrusion using this method (mean: 2.4 mm; minimum: 1.2 mm; and maximum: 4.5 mm; P = .00). Conclusion: The direct use of orthodontic mini-implants was effective for the intrusion of maxillary molars.
