INVESTIGATION THE RETROSPECTIVE CEPHALOMETRIC GROWTH CHANGES OF SAGITTAL AIRWAY IN SKELETAL CLASS 2 PATIENTS WITH COMPLETED FUNCTIONAL THERAPY

Abstract

The aim of this study is to compare the changes in sagittal airway dimension after functionaltreatment. A total of 101 patients, 47 maleand 54 female, wereincluded in the study. Group were formed according to gender and appliance type and in patients with 65 removable (monoblock) and 36 fixed appliances (ForsusTM), Sella-Nasion-A angles (SNA), Sella-Nasion-B angles (SNB), and A noktası-Nasion-B angles (ANB) as airway dimensions; lower airway size (PNS-AD1), upper airway size (PNS-AD2), lower adenoid tissue (AD1-BA), upper adenoid tissue (AD2-HO), superior pharyngeal space (SPS), middle pharyngeal space (MPS) and inferior pharyngeal space (IPS) were measured and recorded. A significant increase was observed in all pharyngeal spaces in boys (p<0.05). While a significant increase was observed in the superior and inferior pharyngeal spaces in girls and in removable appliance group, a significant increase was observed only in the inferior pharyngeal space in fixed group (p<0.05). A significantly decrease in SNA and ANB and an increase in SNB were observed in all groups (p<0.05). The amount of increase in SNB and decrease in ANB were found to be significantly higher in removable group than in fixed group (p<0.05). It was seen that with the functional therapy of skeletal class 2 maloc clusions, both significant increases in sagittalair way dimensions were obtained and normal growth and development were managed.

FONKSİYONEL TEDAVİSİ TAMAMLANMIŞ İSKELETSEL SINIF 2 HASTALARIN SAGİTTAL HAVAYOLUNUN RETROSPEKTİF SEFALOMETRİK BÜYÜME DEĞİŞİKLİKLERİNİN İNCELENMESİ

Abstract

Bu çalışmanın amacı, fonksiyonel tedavi sonrası sagittal havayolu boyutlarında meydana gelen değişikliklerin karşılaştırılmasıdır. Çalışmaya; 47 erkek ve 54 kız toplam 101 hasta dahil edildi. Gruplar; cinsiyet ve aparey tipine göre oluşturuldu.65 adet hareketli (monoblok) ve 36 adet sabit (ForsusTM) aparey kullanılmış hastalarda Sella-Nasion-A açısı (SNA), Sella-Nasion-B açısı (SNB), ve A-Nasion-B açısı (ANB)ve havayolu boyutlarında; alt havayolu boyutu (PNS-AD1), üst havayolu boyutu(PNS-AD2), alt adenoid doku boyutu (AD1-BA), üst adenoid doku boyutu (AD2-HO), üst faringeal boşluk (SPS), orta faringeal boşluk (MPS) ve alt faringeal boşluk (IPS) ölçülerek kaydedildi. Erkeklerde, faringeal boşlukların tümünde anlamlı artma gözlendi (p<0.05). Kızlarda ve hareketli aparey grubunda, üst ve alt faringeal boşluklarda anlamlı artma görülürken, sabit aparey grubunda sadece alt faringeal boşlukta anlamlı artma gözlendi (p<0.05). Tüm gruplarda, anlamlı şekilde SNA ve ANB açılarında azalma ve SNB açılarında artma gözlendi (p<0.05). SNB’de artma ve ANB’de azalma miktarı hareketli aparey grubunda sabit aparey grubuna göre anlamlı şekilde daha fazla bulundu (p<0.05). İskeletsel sınıf 2 maloklüzyonların fonksiyonel tedavisiyle, hem sagittal havayolu boyutlarında anlamlı artışlar sağlanırken hem de normal büyüme ve gelişmenin yönlendirildiği görüldü.
