After eruption of the incisor(s), adjunctive procedures
may be appropriate. For example, gingival surgery might be
performed to recontour the attachment levels between the
adjacent incisors, as the gingival heights are often not
symmetric after delayed or orthodontic eruption. As well,
because of the increased potential for tooth position to
relapse once appliances have been removed, long-term retention
is recommended. The increased risk of relapse most
likely results from the significant initial displacement and
rotation of the tooth. A bonded lingual retainer is often
recommended if the occlusion (overbite) will allow its placement.
If the occlusion is such that a bonded maxillary lingual
retainer cannot be placed, a standard Hawley or vacuum
form retainer may be used. Regardless of the type of retainer,
a longer than average retention period should be used.
