İskeletsel Sınıf II Bölüm I Maloklüzyonların Hareketli Fonksiyonel Apareylerle Tedavisi Sonrası Condylion-Gonion-Menton Açısı ve Dentoalveolar Yüksekliklerdeki Değişikliklerin Değerlendirilmesi

Öz

Amaç: Condylion-Gonion-Menton (CoGoMe) açısı ve dentoalveolar yükseklikler maksillomandibular büyüme ve gelişme hakkında bilgi sağlayan önemli parametrelerdir. Bu çalışmada fonksiyonel tedavi sonrası CoGoMe açısı ve dentoalveoler yüksekliklerde meydana gelen değişikliklerin incelenmesi ve birbirleriyle ilişkili olup olmadığının analiz edilmesi amaçlanmıştır. Gereç ve Yöntemler: Çalışmaya mandibular retrognatiden kaynaklanan iskeletsel sınıf II bölüm I maloklüzyona sahip ve pik döneminde bulunan 38'i kadın (ortalama yaş 11,7 ± 0,6) ve 22'si erkek (ortalama yaş 12,6 ± 0,5) olmak üzere toplam 60 hasta dahil edildi. İskeletsel açıların ve dentoalveoler yüksekliklerin doğrusal ölçümleri, fonksiyonel tedavi öncesi (T0) ve fonksiyonel tedavi sonrası (T1) alınan lateral sefalometrik radyografilerde yapıldı. İstatistiksel analizlerde eşleştirilmiş örneklem t testi, Wilcoxon testi ve Spearman'ın rho korelasyon katsayısı kullanıldı. İstatistiksel anlamlılık p<0,05 olarak kabul edildi. Bulgular: Fonksiyonel tedavi ile CoGoMe açısında anlamlı artış gözlenirken, SN/GoGn açısında anlamlı bir değişiklik saptanmadı. SNA açısında anlamlı bir değişiklik gözlenmezken, SNB'deki artış ve ANB'deki azalma anlamlı bulundu. Anterior dentoalveolar yüksekliklerde anlamlı bir değişiklik gözlenmezken, posterior dentoalveolar yüksekliklerdeki artışların anlamlı olduğu görüldü. Dentoalveolar yükseklikler ile CoGoMe açısı arasında anlamlı bir ilişki bulunmazken, dentoalveolar yükseklikler birbirleriyle pozitif yönde anlamlı ilişki gösterdi. Sonuç: Sonuç olarak: (i)CoGoMe açısı, fonksiyonel tedavi ile mandibular büyümenin izlenmesinde SN/GoGn yerine uygun bir alternatiftir; (ii) dentoalveoler yüksekliklerdeki değişiklikler ile CoGoMe açısı arasında herhangi bir korelasyon yoktur; ve (iii) posterior dentoalveoler yüksekliklerdeki anlamlı artışların, sınıf I ilişkiyi elde etmek amacıyla molar bölgede yapılan selektif möllemenin sonucunda oluşan ekstrüzyondan kaynaklandığı görülmüştür.

Evaluation of the Changes in Condylion-Gonion-Menton Angle and Dentoalveolar Heights After Treatment of Skeletal Class II Division I Malocclusions with Removable Functional Appliances

Abstract

Objectives: Condylion-Gonion-Menton (CoGoMe) angle and dentoalveolar heights are important parameters that provide information about maxillomandibular growth and development. This study aimed to examine the changes in the CoGoMe angle and dentoalveolar heights after functional treatment and to analyze whether they are related to each other. Materials and Methods: A total of 60 patients, 38 females (mean age 11.7 ± 0.6) and 22 males (mean age 12.6 ± 0.5), with skeletal class II division I malocclusion caused by mandibular retrognathia in the peak period were included. Linear measurements of skeletal angular and dentoalveolar heights were made on lateral cephalograms taken pre- (T0) and post-functional treatment (T1). Paired sample t test, Wilcoxon test and Spearman’s rho correlation coefficient were used for statistical analyses. Statistical significance was accepted as p<0.05. Results: While the CoGoMe angle increased significantly with treatment, no significant change was found in the SN/GoGn angle. While no significant change was observed in SNA angle, the increase in SNB and the decrease in ANB were found to be significant. No significant change was observed in anterior dentoalveolar heights. However, increases in posterior dentoalveolar heights were found to be significant. While there was no significant relationship between dentoalveolar heights and CoGoMe angle, dentoalveolar heights showed a positive significant relationship with each other. Conclusion: It was concluded that: (i) the CoGoMe angle was a suitable alternative instead of SN/GoGn for the monitoring of mandibular growth with functional treatment; (ii) there was no correlation between the changes in dentoalveolar heights and the CoGoMe angle; and (iii) the significant increases in posterior dentoalveolar heights were caused by extrusion as a result of selective grindings in the molar region in order to obtain class I relationship.
