ABSTRACT

Objective To study the clinical effect of orthopedic-orthodontic treatment in crossbite in deciduous dentition through cephalmetric analysis. Methods 12 children with crossbite in deciduous dentition were enrolled in treatment group. Control group included 8 patients with normal deciduous dentition. Modified reverse headgear was used in each patient in the treatment group. Orthodontic force was a-bout 2. 94-4. 90 N (300-500 g) , and the direction of force was under occlusion plane for 37 degree. Each patient wore reverse headgear for 10 hour per day. Orthodontic treatment lasted for 6 months, and then orthodontic treatment began at once. Orthodontic treatment was not over until crossbite was corrected. The cephalmetric change was compared between two groups before treatment (T1) , after orthopedic treatment (T2)and after orthodontic treatment (T3). The effect of orthopedic-orthodontic treatment was analyzed in two group. Results Crossbite was corrected successfully in all patients in the treatment group. After treatment, A point moved forward by 2. 8mm, Is-FHp increased 8. 38 mm, <SNA increased 2. 65, incisors in mandible moved backward a little bit. All these changes were statistical different as compared with those in the control group. Conclusion Skeletal and dental deformity are improved progressively after combined orthopedic-orthodontic treatment. It is recommended to perform orthopedic-orthodontic therapy in skeletal crossbite in deciduous dentition.

ABSTRACT

<p><b>OBJECTIVE</b>To Verify the safety and reliability of one-stage repair of complete cleft Lip and palate in infancy and to obtain the primary result.</p><p><b>METHODS</b>The simultaneous repair of complete cleft Lip and palate in infants 3 to 12 months of age were performed in 271 cases. The deformities include 185 cases of typical complete unilateral clefts and 75 cases of complete bilateral clefts, and other 11 atypical cleft infants. The preoperative orthopedic treatment for wide alveolar cleft was undertaken in 24 infants and the lip appearance and speech outcome were evaluated in 116 children by 1 to 4 years' postoperative follow-up.</p><p><b>RESULTS</b>All infants, except for dyspnea in 2 babies, palatal fistula formation in 6 cases and temporary wound hemorrhage in 5 infants, were recovered without complications. After orthopedic treatment, the width of the alveolar cleft was reduced 6.1 mm in average. The evaluation showed that 93.1% of children had got good or excellent lip appearance. And the acceptable or excellent speech was found in 94.8% children.</p><p><b>CONCLUSIONS</b>Simultaneous repair of complete cleft lip and palate in infancy is safety and reliable. The preoperative orthopedic procedure is able to reduce the wide alveolar cleft and to achieve alignment of alveolar segments. The acceptable and or excellent lip appearance and speech function could be obtained in this one-stage operative procedure in infants.</p>
