Rapid maxillary expansion (RME) has proven to be a viable treatment option for space gaining in maxilla. Similarly, mandibular incisor extraction when used in aptly selected cases has been reported to be a valuable adjunctive therapy to relieve tooth size-arch length discrepancy in mandibular arch. However, cases reporting the concomitant use of both these modalities are few. The objective of the present article is to report the successful orthodontic treatment of severe tooth size-arch length discrepancy in an adolescent patient using a combination of nonextraction treatment including RME, proclination of anterior teeth and reproximation in the maxillary arch, and single incisor extraction in the mandibular arch. Through a meticulously planned individualized treatment approach, esthetically and functionally stable results with good occlusion were achieved, which were well-maintained at 3-year follow-up. The favorable treatment outcome and long-term stability achieved substantiates the feasibility of this unconventional treatment option in selected cases.
