Stability of the Maxillary and Mandibular Total Arch Distalization Using Temporary Anchorage Devices (TADs) in Adults

Distalization with temporary anchorage devices (TADs) is commonly used to resolve crowding and correct molar relationships in non-extraction cases. The purpose of this study was quantify the treatment effects post-treatment stability total arch distalization TADs adults thereby elucidate clinical effect modality. subjects were 39 adult orthodontic patients treated TADs. Lateral cephalograms dental casts taken at pretreatment (T0), (T1), retention period (T2, 29.3 ± 12.8 months) evaluate vertical horizontal movement teeth, changes width rotation. It concluded that even though there a little relapse anteroposterior position maxillary mandibular teeth during retention, no obvious facial profile. Therefore, can be moderate amount length discrepancy effectively stable retention.
