عنوان انگلیسی Soft Tissue Profile Changes Following Orthodontic Treatment in Patients With Unilateral Cleft Lip and Palate
چکیده انگلیسی مقاله Background – Anterior crossbite is a common malocclusion in unilateral cleft lip and palate. (UCLP) patients. Several studies have investigated the effects of orthognathic surgery or orthopedic treatment on correction of this malocclusion. Only few studies evaluated the effect of conventional orthodontic treatment on growing patients. Objectives - To scrutinize significant changes of dento-skeleton and facial profile following early orthodontic treatment in UCLP children and to compare the treatment results with the clinical norm.   Material & Methods – Lateral cephalograms of 32 non-syndromic UCLP children (15 boys, 17 girls), mean age 10.91 ± 2.00 years were retrospectively collected. All patients had complete orthodontic records before and after treatments indicating the acceptable treatment result when considered from degree of overbite, overjet, maximum intercuspation occlusion and facial profile. Cephalometric measurements represented dento-skeletal and soft tissue profile before and after treatments were evaluated, and significant changes were tested by paired t-test. One sample t-test was used to analyse significant differences between these measurements and the clinical norm. Results – The initial characteristics of the UCLP patients were skeletal Class III maxillary retrusion with relative mandibular prognathism, retroclination of the incisors, negative overjet, increase overbite and concave facial profile. After conventional orthodontic treatment, mainly maxillary arch expansion and Class III elastic traction, the acceptable overbite and overjet were achieved by proclination of the upper incisors. Significant changes of the soft tissue profile due to facial growth and treatment were increase of facial convexity, nose length, nose depth, columellar length, soft-tissue face height ratio, upper and lower lip lengths and upper lip protrusion. The soft tissue profile after treatment was acceptable when compared with the clinical norm. Conclusion – The early correction of the anterior crossbite with maxillary arch expansion and Class III traction could improve the soft-tissue facial profile of UCLP patients.
