AB  - Objective: The aim of thisstudy was to evaluate the long term results of double plate appliance andfacemask combination (DPA-FM) in treating Class III malocclusions when growthpotential of the patients was close to cease or ceased.Materials and Method: The material consistedof the pretreatment (T1), posttreatment (T2), and long term (T3) lateralcephalometric and the hand-wrist radiographs of 13 patients (5 females, 8 males;mean chronological age: 11.1±1.40 years) with skeletal and dental Class IIImalocclusion treated with DPA-FM combination. The mean DPA-FM treatment timewas 10.8±1.88 months. The hand-wrist growth and developmental stages were MP3uor Ru at T3. The mean follow-up period was 5.0±1.98 years. Friedman’s Two-WayANOVA and Wilcoxon signed-rank tests were used to evaluate the treatment(T2-T1), follow-up (T3-T2) and overall (T3-T1) results.Results: Withthe DPA-FM therapy, SNA and ANB angles increased (p<0.001); however, nosignificant differences were found in these parameters during T3-T2 period[p=0.655 (SNA), p=0.805 (ANB)]. Significant increases were found in N┴FH-A distance duringthe treatment (p<0.01) and follow-up (p<0.05) periods. Molar relation showedsignificant increases with DPA-FM in both the treatment and overall period(p<0.001). Overjet increased significantly during the treatment(p<0.001), follow-up (p<0.05), and overall (p<0.001) periods.Significant protrusion of upper incisors (U1/NA) was observed during thetreatment, follow-up, and overall periods (p<0.05). U6/PP and L6/MP anglesdid not change during the DPA-FM treatment; however, these parameters decreasedsignificantly during the follow-up and overall periods (p<0.05).Conclusion: In the treatment ofClass III malocclusion, the DPA-FM appliance was effective. The skeletal anddental sagittal changes achieved by orthopedic treatment were maintained in thelong term.

N2  - Amaç: Sınıf III maloklüzyonun tedavisinde kullanılan ağız-içi çift plakile yüz maskesi (AÇP-YM) kombine tedavisinin uzun dönem sonuçlarının büyümepotansiyeli bitmiş ya da bitmekte olan hastalarda değerlendirilmesidir.Gereç ve Yöntem: Çalışmanın materyali AÇP-YM kombine tedavisi uygulanmış olaniskeletsel ve dişsel Sınıf III maloklüzyona sahip 13 hastaya (5 kız, 8 erkek;ortalama kronolojik yaş: 11.1±1.40 yıl) ait tedavi öncesi (T1), sonrası (T2) veuzun dönem takip (T3) lateral sefalometrik ve el bilek radyografilerindenoluşturuldu. Ortalama AÇP-YM tedavi süresi 10.8±1.88 aydır. T3 döneminde, elbilek büyüme ve gelişim safhası, MP3u veya Ru dönemidir. Ortalama takip süresi5.0±1.98 yıldır. Tedavi (T2-T1), takip (T3-T2) ve toplam (T3-T1) değişikliklerideğerlendirmek için Friedman iki yönlü ANOVA ve Wilcoxon işaretli sıralartestleri kullanıldı.Bulgular: AÇP-YM tedavisi ile SNA ve ANB açılarında artış bulundu (p<0.001). Ancak buparametrelerde T3-T2 döneminde önemli düzeyde bir değişiklik meydana gelmedi [p=0.655 (SNA), p=0.805(ANB)]. N┴FH-A mesafesi tedavi(p<0.01) ve takip (p<0.05) dönemlerinde önemli düzeyde arttı. Molar ilişkide, hem AÇP-YM tedavisi sırasında hem de toplam süredeönemli düzeyde bir artış meydana geldi (p<0.001). Overjet ise, tedavi(p<0.001), takip (p<0.05) ve toplam sürede (p<0.001) önemli düzeydearttı. Tedavi, takip dönemlerinde ve toplam sürede, üst keserlerde (U1/NA)önemli düzeyde protrüzyon gözlendi (p<0.05). U6/PP ve L6/MP açıları AÇP-YMtedavisi ile değişmezken, takip periyodunda ve toplam sürede bu parametrelerdeönemli düzeyde azalma meydana geldi (p<0.05).Sonuç: AÇP-YM kombine tedavisi, Sınıf III maloklüzyonun tedavisinde etkilibulundu. Bu ortopedik tedavi ile meydana gelen iskeletsel ve dişsel sagitaldeğişikliklerin uzun dönem takip periyodunda korunduğu gözlendi.
