Compare the tooth borne versus fixed orthodontic intrusive system (TADs) for the correction of anterior deep overbite

Full description

this study determined which method was more compliant, efficacy and comfortable. It was performed to evaluate intrusion of upper incisors with applying tooth borne system as Connecticut Intrusion Arch (CIA) and temporary anchorage devices (TADs) [miniscrew] and evaluate the dental and skeletal cephalometric effects of these intrusion methods on individuals with deep bite caused by supraocclusion of upper incisors. It also evaluated oral hygiene and pain sensation in the two groups during the study period.
