Abstract

Abstract: Objective: To investigate the effect of early orthodontic treatment on alveolar bone in patients with cleft lip palate. Methods: Ninety-seven children with cleft lip palate admitted to our hospital from April 2016 to May 2018 were collected and divided into the early orthodontic group (<6 years old, n=55) and the control group (6 years old, n=42) according to their age. Both groups were given orthodontic treatment. The canine spacing, molar spacing, alveolar bone height and density, and masticatory efficiency were measured before and after orthodontic treatment. Then the facial satisfaction scores and complications were recorded. Results: The canine spacing and molar spacing increased in both groups after treatment, and were larger in the early orthodontic group than in the control group (P<0.05). The visual analogue satisfaction scores increased in both groups after treatment, and were higher in the early orthodontic group than in the control group (P<0.05). The alveolar bone height increased in both groups after treatment, and were higher in the early orthodontic group than in the control group (P<0.05). The alveolar bone density showed no difference between groups after treatment (P>0.05). The masticatory efficiency increased in both groups after treatment, and were better in the early orthodontic group than in the control group (P<0.05). Conclusion: Early orthodontic treatment can effectively and safely improve the dental arch relationship of children with cleft lip palate, optimize the health status of alveolar bone, and improve the masticatory efficiency.

Key words: cleft lip palate, early orthodontic treatment, maxillary arch width, alveolar bone, masticatory efficiency
