| Resumo: |
Cleft lip and palate are common birth defects. Cleft patient undergone many surgical procedures in the midface, in early ages, that may affect the facial growth. This can result in midface deficiency and class III malocclusion that requires protraction of the maxila or surgical treatment. The maxillary advancement is the main procedure performed to treat patients with midface retrusion. One of the treatment alternatives, consists of using skeletal anchorage and elastics. However, these patients with cleft lip and palate usually present a nutritional deficiency in the early childhood, leading us to question about a possible compromise of their bone quality. The aim of this research was to evaluate the bone condition in the lower Canine regions (distal and mesial) and upper permanent first molars (mesial) using Cone Beam CT in individuals with and without cleft lip and palate, with and without growth potential. No statistical significant differences were found in the measures evaluated among the three groups. The values of cortical thickness and Gray Scale were similar in patients with and without cleft lip and palate, and with growth potential, when compared to adults. Therefore, patients with growth potential and cleft lip and palate have the same bone conditions for receiving mini implants as the adult patients without cleft lip and palate. |
