53 months (25 months post-deband)
The patient was reviewed 25 months following the completion of active orthodontic treatment. (Figure 7). The overall alignment and tooth interdigitation had been maintained. The 26 was noted to be in a posterior lingual crossbite position, however, this minor irregularity did not present any aesthetic or functional concerns. The 38 and 48 were noted to be partially erupted with a very high likelihood of gaining acceptable antagonistic contact with the opposing 17 and 27. An updated panoramic radiograph (Figure 8) demonstrated that alveolar bone regeneration had occurred in the fourth quadrant and that the eruption path of the developing 38 and 48 appeared favourable.
