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

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.

Inclusion Criteria:

1. Class I or Class II malocclusion with minimal crowding.
2. 70% to 100% overbite.
3. High lip line with gingival display on smiling and super-eruption of maxillary incisors.
4. All patients had permanent dentition with average to vertical growth pattern and curve of Spee of 4mm or less.

Exclusion Criteria:

1. Having missing teeth on the anterior maxillary area.
2. Any history of trauma or root canal treatment.
3. Previous orthodontic treatment.
4. Low lip line duing social smile.
