Year 2015, Volume: 42 Issue: 3 - Volume: 42 Issue: 3, 177 - 184, 01.02.2015

Abstract

Distal malocclusions are the most common type of anomaly in the society. Skeletal malocclusions cause the emergence of different face types. These anomalies, can be prevented or treated by the elimination or reduction of abnormal function. Functional appliances are widely used for treatment of these anomalies. These appliances conduct the strength of certain muscle groups through the dentition to the basal bone by changing the function and position of the mandible. Although there are many studies on the mechanism of action of functional appliances, the results are still controversial. In this study, the effect of two different activators used in the treatment of Class II Division 1 anomalies on the sagittal development of maxilla and mandibula were compared. The study was carried out on; group 1 consisting of 21 patients 11 girls, 10 boys with an average of 13 treated with herbst, group 2 consisting of 17 patients 10 girls, 7 boys with an average age of 12 treated with monoblock, group 3 consisting of 16 patients 9 girls, 7 boys with an average age of 12 treated with monoblockHeadgear combination, group 4 consisting of 19 nontreated patients 11 girls, 8 boys with an average age of 12 In order to test the similarity of the values at the treatment/control beginning and end within the groups, Variance analysis, t and Duncan test were applied to the initial and final cephalometric values. Consequently, it was determined that the provocation of the mandibulary development depends not on activator design, but the amount of activation and everyday use of appliance, but the inhibition of the maxillary development is still a point of contention.

Abstract

Distal maloklüzyonlar toplumda en çok yayılmış anomali tipidir. İskeletsel maloklüzyonlar değişik yüz tiplerinin ortaya çıkmasına neden olmaktadır. Bu anomalilerin, anormal fonksiyonların ortadan kaldırılması ya da azaltılması ile önlenebileceği, tedavi edilebileceği belirtilmektedir. Tedavi amacıyla fonksiyonel aygıtlar geniş kullanılmaktadırlar. Bu aygıtlar, mandibulanın fonksiyon ve pozisyonunu değiştirerek belli bir kas grubunun kuvvetini dentisyon aracılığıyla bazal kemik kaidesine yönlendiren aygıtlardır. Fonksiyonel apareylerin etki mekanizması ile ilgili birçok araştırma yapılmasına rağmen, sonuçlar halen tartışmalıdır. Makalede sınıf II, bölüm 1 maloklüzyonların tedavisinde kullanılan 2 farklı aktivatörün maksilla ve mandibulanın sagittal gelişimi üzerindeki etkileri kıyaslanmıştır. Araştırma 1. grup herbst aygıtıyla tedavi edilmiş ve yaş ortalamaları 12 olan 21 hastadan 11 erkek, 10 kız , 2. grup monoblok aygıtıyla tedavi edilmiş ve yaş ortalamaları 12 olan 17 hastadan 10 kız, 7 erkek , 3. grup monoblokHeadgear kombinasyonuyla tedavi edilmiş ve yaş ortalamaları 12 olan 16 hastadan 9 kız, 7 erkek , 4. grup ise tedavi edilmemiş ve yaş ortalamaları 12 olan 19 hastadan 11 kız, 8 erkek oluşan gruplar üzerinde yürütülmüştür. Gruplar içinde tedavi/kontrol başında ve sonundaki değerlerinin benzer olup olmadığının test edilmesi amacıyla başlangıç sonuç sefalometrik değerler arasında Varyans analizi, t ve Duncan testi uygulanmıştır. Sonuç olarak mandibular gelişimin provokasyonu aktivator dizaynından değil, aktivasyon miktarından ve aygıtın günlük kullanımından esinlenmekte olduğu, fakat maksillar inkişafın inhibisyonunun tartışma konusu olduğu belirlenmiştir
