OBJECTIVE Assessment of the influence of maxillary lateral incisor agenesis (MLIA) on the facial morphogenesis. METHODS Evaluation of the skeletal dimensions of the upper maxilla and its incisor region. Analysis was performed among three groups: individuals with MLIA, its relatives and the normal population. Among these a comparison between adults and growing individuals was performed. RESULTS MLIA may interfere with the maxillary length and the anterosuperior facial height, negatively conditioning on its potential growth. MLIA was not correlated with changes of the palatine plane inclination, maxillary height nor with adjustment of the anterior nasal spine dimensions related to the Frankfurt plan or to the posterior nasal spine-Frankfurt plan during the observed development stage; the backward angle of the incisors in children with bilateral agenesis of lateral incisors appear to have been corrected in adulthood. CONCLUSIONS MLIA is associated with an upper maxilla shortening, and appear to interfere significantly with the anterior facial height, reducing its potential size.

D014716 Vertical Dimension The length of the face determined by the distance of separation of jaws. Occlusal vertical dimension (OVD or VDO) or contact vertical dimension is the lower face height with the teeth in centric occlusion. Rest vertical dimension (VDR) is the lower face height measured from a chin point to a point just below the nose, with the mandible in rest position.
