ORTHODONTIC : Malocclusion in Down syndrome - a review


Down syndrome or Trisomy 21 is a genetic disorder, which results in intellectual impairment, typical craniofacial features and a wide spectrum of phenotypic abnormalities.

Characteristic features of midface hypoplasia in Down syndrome include smaller maxilla, presence of 'stair' palate and severe malocclusion.

Generally, the most frequent malocclusions stem from variations in vertical and transverse occlusions, identified mainly as Angle's Class III molar relations, anterior open bite, anteroposterior crossbite, and proclination of the anterior teeth.
