Deep-bite is a common component of malocclusion in adults and children. The most commonly used technique for incisor intrusion is the utility arch technique given by Dr Ricketts. In recent times mini-implants are used as anchorage units in orthodontics to bring about tooth movement. The aim of this in-vivo study was to analyze the skeletodental changes occurring during deep overbite correction with mini-implant anchorage system and the utility arches reinforced by a transpalatal arch. From the results our study, we can conclude that the mini-implant technique for true incisor intrusion can be considered superior to the conventional utility arches. Vertical height of molars does not change much with implants and utility arches reinforced by a transpalatal arch. Change in incisor inclination is not seen with mini-implants but significant change in the incisor inclination is seen with the utility arches. Very few studies give a direct comparison between the effects of different types of...
