After a 6-month pause, and following the necessary primary tooth extractions and eruption of the lower second premolars, it was possible to resume the treatment. During the pause, there was spontaneous improvement amongst the buccal occlusion, and minimal patient cooperation was required with retention.

Fig. 11.11 After correction of palatally positioned permanent canines, it is helpful to place a local bonded labial retainer, in addition to conventional upper removable retention. Such teeth have a strong probability of relapse, and removable retention is seldom adequate.

In other cases, it may be helpful to provide local bonded labial retention for a few teeth, in addition to vacuum-formed retainers. For example, this is helpful after correction of severely rotated teeth or palatally placed canines (Fig. 11.11), which have a high probability of relapse, and which are not well retained using only Hawley or vacuum-formed retainers.
