CASE REPORT Fig. 14 upper and lower molar bands. One week later bands and brackets were placed along with a habit breaking appliance involving tongue thrust loops. Johns Dental (Fig. 6) and an initial .0175 twisted archwire. After months of straight wire archwire sequence of wires, powerchains were used to close the spaces between all teeth. After one year the habit breaking appliance was removed and the archwire sequence was continued until all spacing was closed and the open bite corrected. On May 24th, 2012 the bands and brackets were removed. (Figs. 8 & 9) An upper Hawley retainer was delivered and a lower lingual anterior retainer wire was bonded from #22 -#27. The active treatment time was nineteen months. At the time of final records the patient had achieved a Class I canine and molar rela-tionship with improved facial esthetics and the loss of her tongue thrust. Generally a tongue thrust swallow-ing pattern can be handled in two ways, mechanical or retraining of muscles. The mechanical method of plac-ing an appliance in the mouth worked well here. (Figs. 10, 11, 12) In addition correction can also be achieved by oral habit training this involves an exercise tech-nique that re-educates the muscles associated with swallowing by changing the swallowing pattern.
