Upper occlusal plane rotation using miniplates in open bite with deep bite malocclusion: Two case reports

Marcel Marchiori FARRET, Carlos Eduardo BALBINOT, Felipe Foschiera TRINDADE

Introduction: Patients with open bite and deep bite usually have the upper and lower occlusal planes rotated in clockwise or counterclockwise direction. In these cases, the upper occlusal plane may be modified through the posterior intrusion or anterior intrusion, to achieve a good functional and aesthetic result. Methods: The effective rotation of the upper occlusal plane was always one of the main challenges of orthodontic treatments, because it was difficult to obtain a remarkable change without side effects or the extreme cooperation of patients. The skeletal anchorage brought new possibilities to these cases, increasing the amount of orthodontic movement, reducing or eliminating side effects, and sometimes even eliminating the necessity of orthognatic surgery. Results: This manuscript reports two cases of patients with open bite and deep bite, respectively, treated with miniplates in the posterior region of the maxilla, used to rotate the upper occlusal plane. The results showed remarkable rotation of the upper occlusal plane in both cases, with good esthetic, and functional results at the end of treatment.
