Abstract

ABSTRACT
Aim: The aim of this retrospective study was to investigate the effects of different vertical growth pattern on sagittal structures.
Material and Methods: The material consisted of cephalometric films of untreated 50 Class II subjects, 24 boys and 26 girls, aged 9 to 12 years. Subjects were divided into three groups with increased vertical facial growth pattern (SN/GoGn>320), normal vertical facial growth pattern (280≤SN/GoGn≤320) and decreased vertical facial growth pattern (SN/GoGn<280). Differences between vertical groups were assessed by the means of variance analyses and least significant difference (LSD) test. And correlation coefficient between vertical groups and other variables were calculated.
Results: SNA (p<0.01), SNB (p<0.05), Gonial angle (p<0.001), Jarabak ratio (p<0.001) and IMPA (p<0.01) were found to be related with vertical growth pattern. Negative correlation was found between SN/GoGn and SNA, SNB, IMPA angles and Jarabak ratio, and also positive correlation was observed between SN/GoGn and Gonial angle.
Conclusion: The change in vertical growth pattern influenced sagittal parameters of face.
Keywords: growth and development, maxilla, mandible, vertical dimension, maxillofacial development


ÖZ
Amaç: Bu retrospektif çalışmanın amacı farklı vertikal yüz gelişim paterninin sagittal yapılar üzerine olan etkisini incelemektir.
Gereç ve Yöntem: Çalışma materyalini, yaşları 9 ile 12 arasında değişen 24 erkek ve 26 kız olmak üzere tedavi edilmemiş 50 Sınıf II vakanın sefalmetrik filmleri oluşturmaktadır. Bireyler dikey yüz büyümesi artmış bireyler (SN/GoGn> 320), dikey yüz büyümesi normal olan bireyler (280≤SN/GoGn≤320) ve dikey yüz büyümesi azalmış bireyler (SN/GoGn<280) olmak üzere 3 gruba ayrılmıştır. Vertikal gruplar arasındaki farklılıklar varyans analizi ve LSD testi ile değerlendirilmiştir. Dik yön ile diğer değişkenler arasındaki korelasyon katsayısı belirlenmiştir.
Bulgular: SNA (p<0.01), SNB (p<0.05), Gonial açı (p<0.001), Jarabak oranı (p<0.001) ve IMPA (p<0.01) farklı vertikal gelişim paternleriyle ilişkili bulunmuştur. SN/GoGn ile SNA, SNB, IMPA açıları ve Jarabak oranı arasında negatif, Gonial açı ile de pozitif korelasyon saptanmıştır.
Sonuç: Dikey yüz gelişimdeki değişiklikler yüzün sagittal gelişimi etkilemektedir.
Anahtar Kelimeler: büyüme ve gelişim, maksilla, mandibula, vertikal boyut, maksilofasiyal gelişim
