"In orthodontics, functional appliance can be used as a preliminary appliance in treating class II malocclusion with retruded mandible. This type of removable appliance needs patient's full cooperation. However, there is one type of a fixed functional appliance, known as : Herbst Appliance, which was introduced by Herbst in 1909 and was redeveloped by Pancherz in 1979. By using this appliance, the treatment period is much shorter compared to that of other removable functional appliances and the results is more effective. This telescopic mechanism principle produces posterior forces to maxillary dentoalveolar complex and anterior forces to mandibular dentoalveolar complex. The expected effect of the treatment is longer mandible, distal movement of upper molars, mesial movement of lower molars, higher vertical dimension and a decrease of profile convexity. Based on those facts, in treating class II malocclusion-division I or II - a Herbst appliance might be taken into consideration."

"Tujuan: Menganalisis hubungan antara ukuran saluran pernapasan faring pada maloklusi kelas I dan II dengan pola pertumbuhan skeletal vertikal. Metode : Penelitian potong lintang ini melibatkan 126 sampel dengan usia 20-40 tahun yang dipilih secara konsekutif dan dibagi menjadi 2 grup berdasarkan sudut ANB yaitu : maloklusi kelas I dan II, kemudian dikelompokkan lagi menjadi 6 kelompok uji berdasarkan pola pertumbuhan skeletal vertikal (hipo-, normo-, dan hiperdivergen). Saluran pernapasan faring atas dan bawah diukur menggunakan analisis McNamara, sementara panjang saluran pernapasan faring diukur dari titik PNS-Eb. Uji hubungan ukuran saluran pernapasan faring dengan pola pertumbuhan skeletal vertikal dilakukan menggunakan uji Pearson’s Chi-Square dan dilanjutkan dengan uji korelasi Gamma untuk melihat arah hubungannya. Hasil: Analisa statistik menunjukkan tidak ada hubungan antara lebar saluran pernapasan faring atas dan bawah pada maloklusi kelas I dan II dengan pola pertumbuhan skeletal vertikal. Panjang saluran pernapasan faring pada maloklusi kelas II juga menunjukkan tidak ada hubungan dengan pola pertumbuhan skeletal vertikal, berbeda dengan maloklusi kelas I yang menunjukkan adanya hubungan antara panjang saluran pernapasan faring dengan pola pertumbuhan skeletal vertikal. Kesimpulan: Meskipun hasil analisa statistik menunjukkan tidak ada hubungan, akan tetapi lebar saluran pernapasan faring atas pada maloklusi kelas II menunjukkan pola yang unik yaitu saluran pernapasan faring atas menyempit pada pola pertumbuhan skeletal vertikal yang semakin divergen. Temuan unik lainnya dari penelitian ini adalah panjang saluran pernapasan faring berkorelasi positif dengan pola pertumbuhan skeletal vertikal pada maloklusi kelas I, yaitu semakin panjang saluran pernapasan faring dengan meningkatnya pola pertumbuhan skeletal vertikal.
Objective: To analyse the correlation between the pharyngeal airway morphology in class I and II malocclusions with vertical skeletal growth patterns. Methods: This cross-sectional study was involved 126 samples aged 20-40 years who were selected by consecutive sampling and divided into 2 groups; class I and class II malocclusions according to ANB angle. This group will be further be divided into 6 test groups based on the vertical skeletal growth patterns (hypodivergent, norm divergent, and hyperdivergent). Upper and lower pharyngeal airway width were measured using McNamara analysis, while pharyngeal airway length was measured from the PNS-Eb point. Pearson's Chi-Square test was used to test the correlation between pharyngeal airway morphology and vertical skeletal growth patterns and proceed with the Gamma correlation test to see the direction of the correlation. Results: Statistical analysis showed that there was no correlation between the upper and lower pharyngeal airway width in Class I and II malocclusions with vertical skeletal growth pattern. The length of the pharyngeal airway in class II malocclusion also showed no correlation with the vertical skeletal growth pattern, in contrast to the class I malocclusion which showed a statistical correlation between the pharyngeal airway length and the vertical skeletal growth pattern. Conclusion: Although the results of statistical analysis showed no statistical correlation, the upper pharyngeal airway width in class II malocclusion showed a unique trend, that the upper pharyngeal airway width narrowed with an increasingly vertical skeletal growth pattern. Another trend finding from this study is that the length of the pharyngeal airway is positively correlated with the vertical skeletal growth pattern in class I malocclusion i.e., the longer the pharyngeal airway, the greater were the vertical skeletal growth pattern."
