Subject of dissertation: The development of maxilla in children with congenital unilateral complete cleft lip, alveolus and palate ( from birth till 5 years of age) Key words groups: congenital unilateral total cleft lip, alveolus and palate, development of maxilla from birth till 5 years of age, cleft severity, lip surgery, palate surgery, maxillary dental casts, occlusion. Objects of dissertation: maxillary dental cast of patients with congenital unilateral complete cleft lip, alveolus and palate Research: The study examined 48 patients with congenital unilateral total cleft lip, alveolus and palate treated at the Žalgiris Clinic of Vilnius University Hospital in the period of 2000-2009. In examined patients lip surgery was performed at 3 months and palate surgery at 18 months of age. The study employed maxillary dental casts at 3 and 18 months of age and upper jaw and lower jaw dental casts at 5 years of age in the same patients. In our research we evaluated changes of maxillary linear and angular measurements and relationship between cleft severity and maxillary linear and angular measurements and occlusion at 5 years. Conclusions: During the study, changes in maxillary measurements in patients with congenital unilateral complete cleft lip, alveolus and palate after lip and palate surgery were analysed. Statistically reliable differences in measurements of maxillary measurements of five-year-old patients with congenital unilateral complete cleft lip, alveolus and palate and in children in the control group were found. A statistically reliable correlation was found between maximum primary alveolar and palatal cleft width and maxillary shape and measurement in children at 3, 18 months and 5 years of age and occlusion at 5-years of age. |
