Abstract

Maxillary transverse deficiency often manifests as a posterior crossbite or edgeto- edge bite and anterior crowding. However, arbitrary arch expansion in mature patients has been regarded as challenging due to possible periodontal side effects such as alveolar bone dehiscence and gingival recession. To overcome these limitations nonsurgical maxillary expansion of the basal bone in young adults has been demonstrated. Meanwhile, the age range for successful orthopedic expansion has often been questioned possibly due to the underlying individual variation in the suture maturity. This case report illustrates nonsurgical, miniscrew-assisted palatal expansion (MARPE) in a 60-year-old patient with maxillary transverse deficiency accompanied by anterior and posterior crossbites, crowding and gingival recession. The use of MARPE allowed the relief of crowding and the correction of crossbite without causing significant periodontal side effects.
