This case report illustrates an orthodontic treatment of a 23-year-old female patient presented with an Angle Class II malocclusion, open bite, bimaxillary dental protrusion and incompetent lips with the aid of titanium miniplates. After extraction of her maxillary first bicuspids and mandibular second bicuspids, fixed pre-adjusted bi-dimensional Edgewise appliances were placed. After alignment, titanium miniplates were surgically placed into the zygomatic buttresses bilaterally. Anterior retraction and intrusion, as well as posterior intrusion were performed. Treatment time was 20 months. Cephalometric superimpositions showed favourable maxillary molar intrusion and mandibular autorotation. Open bite was corrected and class I molars and canines with ideal overjet were achieved with a significant improvement on appearance. Orthodontic treatment with miniplates is an effective technique in open bite cases with vertical problems.
