편측성 완전 구순 구개열 환자의 구개열 형태 및 치궁의 분석

다국어 초록 (Multilingual Abstract)

The aim of treatment of cleft lip and palate is to correct the cleft and associated problems surgically and thus hide the anomaly so that patients can lead normal lives. This correction involves surgically producing a face that does not attract attention, a vocal apparatus that pemits intelligible speech, and a dentition that allows optimal function and esthetics.
In neonatal pe1iods, gross distortion of tissues surrounding the cleft requires considerable effort and time due to post operative functional defect and scarring and induces milk feeding problem, malocclusion of deciduous or permanent dentition, congenital missing teeth, skeletal dysplasia. The occurrence of a cleft deformity is a source of considerable shock to the parents of an afflicted baby, and the most appropriate approach is very important things,
Thus we tried to analysis of dental arch, shape and size of deformity in cleft patients.
The results were obtained as follows.
1. When the cast measurements of UCLP subjects at first visit it was found that the mean length was 9. 29mm at the alveolar cleft width, also that was 11.7mm at the anterior width and 14mm at the posterior cleft width.
2. Comparison of UCLP group at first visit and just lip surgery, it was found that the older group showed a insignificant reduction in the width of the cleft in the alveolar, canine, and tuberosity regions.
3. The maxillary casts of the UCLP group at 6 months differ significantly from those of the at 3 months in both length and width. but there was no statistical difference except anterior ridge length of nonclefted site.
4. Comparison at 6 months and 18 months, there was a greater change in length of the alveolar cleft width, intercanine width, and anterior cleft width. Maxillary arch became wider at both the canine region and intertuberosity region. also posterior anteroposterior length was increased but anterior AP length was decreased from 8.1mm to 7.7mm.
There was meaningful increase at intertl.1berosity length; however, a sigr1ificant reduction in width t-t
