Abstract

OBJECTIVE: To evaluate the effects of face mask therapy (RH) on middle cranial base and maxillo-mandibular complexes, and to compare the responses with untreated class 3 subjects.MATERIALS AND METHOD: The treatment group comprised 20 skeletal class 3 children (14 girls, 6 boys; mean age: 11 years 3 months) treated with RH assisted by rapid maxillary expansion (mean treatment time: 9.6 months). The control group included 22 skeletal class 3 subjects (9 girls, 13 boys; mean age: 10 years) observed for 9.5 months. Cephalometric measurements were performed by counterpart analysis. For intragroup statistical comparisons paired t-test, and for intergroup comparisons independent t-test was used.RESULTS: The treatment group revealed significant increases for SNA, ANB, SN-GoGn, Co-A and Co-Gn (p<0.001), and decrease for SNB (p<0.001). The treatment group revealed significant increases in the effective dimension of the middle cranial base (Ar-SE, p<0.05; So-Hor, p<0.001), maxilla (p<0.001), and anterior-posterior nasomaxillary complex (p<0.001, p<0.05, respectively), and decrease in the effective dimension of the mandibular corpus (p<0.05). According to the intergroup comparisons, treatment group revealed more pronounced maxillary advancement (p<0.001), posterior rotation in the mandible (p<0.001), significant increase in the effective dimension of the middle cranial base (So-Hor, p<0.01) and decrease in the effective dimension of the mandibular corpus at a significance level of p<0.001.CONCLUSION: Revealed by the effects on the middle cranial base morphology, favorable treatment responses were achieved with the use of the RH technique.

Özet

AMAÇ: Çalışmanın amacı, ortopedik yüz maskesi (RH) tedavisinin orta kraniyal kaide ve üst ve alt çene kompleksindeki etkilerini counterpart (eşdeğer) analizi ile değerlendirmek ve tedavi görmemiş Sınıf 3 bireylerle karşılaştırmaktır.GEREÇ VE YÖNTEM: Tedavi grubu; üst çenede hızlı genişletme ile birlikte RH tedavisi görmüş ve üst çenesinde retrognati bulunan 20 iskeletsel Sınıf 3 bireyden (14 kız, 6 erkek; ortalama yaşları: 11 yıl 3 ay) oluşmaktadır. Ortalama tedavi süresi 9.6 aydır. Kontrol grubu ortalama 9.5 ay takip edilmiş 22 iskeletsel Sınıf 3 bireyden (9 kız, 13 erkek; ortalama yaşları: 10 yıl) oluşmaktadır. Sefalometrik değerlendirme eşdeğer analizi ile gerçekleştirilmiştir. Grup içi karşılaştırmalarda eşleştirilmiş t-testi; gruplar arası karşılaştırmalarda bağımsız t-testi kullanılmıştır.BULGULAR: SNA, ANB, SN-GoGn açıları, Co-A, Co-Gn boyutları tedavi ile önemli düzeyde artarken (p<0.001), SNB açısı azalmıştır (p<0.001). Tedavi grubunda orta kraniyal kaide boyutları (Ar-SE, p<0.05; So-Hor, p<0.001), üst çene (p<0.001) ve ön-arka nazomaksiller komplekste artış (p<0.001, p<0.05, sırasıyla) ile mandibuler korpus boyutunda azalma (p<0.05) bulunmuştur. Gruplar arası karşılaştırmada, üst çene ileri yön büyümesinin tedavi grubunda daha belirgin olduğu (p<0.001), alt çenede posterior rotasyon oluştuğu (p<0.001), kontrol grubunda orta kraniyal kaide boyutu değişmezken tedavi grubunda önemli artış olduğu (So-Hor, p<0.01) ve mandibuler korpus boyutundaki azalmanın p<0.001 düzeyinde olduğu bulunmuştur.SONUÇ: Büyüme dönemindeki iskeletsel Sınıf 3 bireylerde RH tedavisi ile orta kraniyal kaide boyutlarında artış ve mandibuler korpus boyutunda azalma ile önemli tedavi etkileri gözlenmektedir.
