This case report describes the treatment of a 23-year, 8-month-old female patient with a Class II malocclusion who showed severe bidentoalveolar protrusion and anterior crowding. The treatment plan consisted of extracting all the first premolars, decrowding and en masse retraction of the upper six anterior teeth and lower anteriors. The upper C-plate placed in the midpalatal area combined with lingual sheath fixtures were used as substitutes for posterior anchorage teeth during upper anterior retraction. Preadjusted brackets (0.022-inch) were used for upper anterior decrowding. A 0.9 mm diameter stainless steel lever-arm soldered to the main arch wire facilitated controlled retraction of upper anteriors. The upper and lower dentition was detailed using a tooth positioner during the finishing stage. Correct overbite and overjet were obtained by decrowding and retraction of the upper six anterior teeth into their proper positions. Use of the C-plate and lingual appliances provided ideal anchorage to enhance the improvement in facial balance. The active treatment period was 19 months. The treatment result was stable 13 months after debonding.
