The purpose of this prospective clinical study was to investigate differences in outcomes from two common treatment modalities used to reduce deep overbite: maxillary incisor intrusion using an intrusion arch and posterior tooth eruption using an anterior bite plate. Pre-treatment, post-overbite correction and post-treatment records were gathered from 32 patients who presented with deep overbite malocclusions to the Virginia Commonwealth University orthodontic clinic. Both groups of patients experienced reductions in overbite and maxillary incisor display as well as maxillary and mandibular incisor proclination and mandibular incisor occlusal movement during treatment. In the intrusion arch group, the center of resistance of the maxillary incisor was significantly intruded during overbite correction. The maxillary incisor incisal edge was significantly more intruded at the end of treatment in the intrusion arch group. Both groups experienced flattening of the smile arc in agreement with previous studies showing similar changes in orthodontically treated individuals.
