Summary
Maxillary
midline diastema is a common aesthetic concern of dental patients.
Various treatment modalities have been employed to close diastemas. This
case report describes an unusual orthodontic treatment approach for a
25-year-old African American female patient with a large maxillary
midline diastema of 5 mm, bialveolar dental protrusion and unilateral
Class III malocclusion. The treatment included one mandibular incisor
extraction, followed by retraction of the incisors. At the end of the
16-month active treatment period, favourable aesthetic and occlusal
outcomes were attained. Closure of midline diastema, good overjet and
overbite with Class I molar relationships were achieved.
Clinical significance
Fixed
orthodontic treatment with single mandibular incisor extraction can be
an effective treatment choice for a large maxillary midline diastema.
With careful selection of the case and treatment planning, successful
results can be obtained.
