ABSTRACT

The difficulties called triple T occur in cases in which the upper and lower teeth do not articulate with each other, both in the anterior part and in the posterior part. Diagnosis: Female patient presents class I molar and canine, with slight anterior crowding, horizontal and vertical overbite of 1 mm. Treatment objectives: Alignment and dental leveling in order to obtain an adequate functional occlusion keeping class I molar and canine. Treatment: Conventional fixed appliances, prescription MBT slot 0.022’’, for the treatment of the triple T problem we used a 0.017’’ × 0.025’’ stainless steel arch with negative torque in the lower incisors, performing stripping in the anteroinferior area and finally using elastic 3/16 of 4.5 oz to achieve a greater settlement. Results: Transversal and sagittal changes were achieved primarily of dental and functional type with favorable facial results.
