Abstract |
It is difficult to perform orthodontic treatment for cleft lip and palate patient. Although there are many orthodontic appliances to expand narrowed maxillary arch, results are rarely successful and the possibility of relapse is increased due to severe scars. Self-ligating bracket, recently used in orthodontic treatment, suggests solution of crowding by expansion of dental arches. Light and continuous force could apply for orthodontic movement due to characteristic low friction of self ligating bracket, which gives expansion force until dentition reaches its new equilibrium position and it can be expressed as spontaneous lateral expansion with heavy labial tension. This kind of expansion force is thought to be a possibility of expanding the constricted maxillary arch of cleft lip and palate patient. Repositioning of the maxilla by Le Fort I osteotomy in case of severe maxillary deficiency, increases the possibility of relapse because of limitation in anterior movement and adaptation of soft tissue. In these cases, distraction osteogenesis(DO) can be applied for stable result. We report a case of cleft lip and palate patient with narrowed maxillary arch and maxillary deficiency using self ligating bracket and DO. |
