Abstract

Objectives: This study compared the skeletal and dental changes obtained by incisor intrusion using three methods: utility intrusion arch (UIA), Connecticut intrusion arch (CIA), and miniscrews.

Materials and methods: A total of thirty-eight patients with age range of 14-25 years were included which were divided into three groups: Group I (n = 13), UIA; Group II (n = 13), CIA; and Group III (n = 12), miniscrew. All the groups were further subdivided into maxillary and mandibular arch. Intrusion force of 60 g and 40 g was used for maxillary and mandibular arch respectively for standardization. Intrusion was concluded after 5-6 months or when correction was achieved. Pre-treatment and post-treatment skeletal and dental changes were compared sing lateral cephalograms.

Results: The results suggested that all three methods were effective means of intrusion, but true intrusion measured from center of resistance was maximum in miniscrew group. No anchorage loss and change in axial inclination of incisors was observed in miniscrew group as compared to UIA and CIA group. Overbite decreased in all groups but more significantly in miniscrew group.

Conclusions: Miniscrew intrusion was considered the preferred method of true intrusion to correct deep bite.
