Objective
The objective of this presentation is to show changes in soft tissue, dental and skeletal parameters after en-masse retraction with TADs.
Cases
Case -1 18 year old female, with maxillary protrusion, Angle’s Class I molar relationship on left side and end-on molar relationship on right side, overjet 13 mm and deep bite 90%. Extraction of 14,24,34,45 was done. Anchorage augmentation done with nance palatal arch and mini screws between 15, 16 and 25, 26. A molar stabilizing arm was placed in auxiliary tube of 16, 26 and a hook was bent on upper side in sulcus. Keyhole loop was fabricated in SS arch wire (0.019 × 0.025) and 9 mm coil spring used for en-masse retraction of maxillary anterior teeth which took 9 months.
Case-2 21 years old female having Angle’s class I molar relationship with bimaxillary dentoalveolar protrusion. Banding of all 1st and 2nd molars was done. 14,24,34 and 44 were extracted , straight wire appliance was placed with TADs between second premolars and first molars in all four quadrants. Closed coil spring was placed between TADs and soldered hook mesial to canine bracket in 0.019X0.025 SS wire. Complete en-masse retraction took 13 months.
Discussion and summary
TADs are probably the most recent research and clinical agenda of today’s orthodontics. The orthodontic treatment mechanics has revolutionized after the introduction of TADs as an anchorage device. Remarkable changes in soft tissue and dentoskeletal parameters in lateral cephalogram were noted in both the cases.
