The aim of this study was to investigate the effects of orthodontic treatment on the mandibular condyle head bone formation according to different orthodontic malocclusion groups. Materials and Methods: In the study, forty-eight patients were examined. Individuals included in the study were grouped according to malocclusion groups. Our study was carried out retrospectively. The quality of mandibular condyle bone in panoramic images of patients before and after orthodontic treatment were compared retrospectively. This examination was carried out by a fractal analysis method. Results: According to the findings we obtained from our study; the change in mandibular condyle bone quality before and after orthodontic treatment by age and gender was not found to be statistically different. After orthodontic treatment in individuals with Class I and III malocclusions, the trabecular density structure of the mandibular condyle bone increased and decreased in individuals with Class II malocclusion. The change in mandibular condyle bone quality before and after orthodontic treatment by malocclusion groups was found to be statistically different. Conclusion:The fractal analysis method is a technique that facilitates the diagnosis of minimal changes occurring on the radiographs of orthodontic treatment patients and to evaluate the prognosis of the disease. A relationship was found between orthodontic treatment applied to different malocclusion groups and mandibular condyle head bone formation. When evaluating orthodontic treatments, mandibular condyle head bone formation should be taken into consideration. Amaç: Bu çalışmada, ortodontik tedavinin mandibular kondil başı kemik oluşumu üzerine etkilerinin farklı ortodontik maloklüzyon gruplarına göre araştırılması amaçlanmıştır. Gereç ve Yöntem: Çalışmada kırk sekiz hasta incelendi. Çalışmaya dahil edilen kişiler maloklüzyon gruplarına göre gruplandırıldı. Çalışmamız geriye dönük olarak yapıldı. Hastaların ortodontik tedavi öncesi ve sonrası panoramik görüntülerinde çene kondil kemiğinin kalitesi retrospektif olarak karşılaştırıldı. Bu inceleme fraktal analiz yöntemi ile yapılmıştır. Bulgular: Çalışmamızdan elde ettiğimiz bulgulara göre; yaşa ve cinsiyete göre ortodontik tedavi öncesi ve sonrasında mandibular kondil kemik kalitesindeki değişim istatistiksel olarak farklı bulunmadı. Sınıf I ve III maloklüzyonlu bireylerde ortodontik tedavi sonrası mandibular kondil kemiğinin trabeküler yapısında densite azalması olmuştur. Sınıf II maloklüzyonlu bireylerde mandibular kondil kemiğinin trabeküler yapısı densite artması olmuştur. Maloklüzyon gruplarına göre ortodontik tedavi öncesi ve sonrası mandibular kondil kemik kalitesindeki değişim istatistiksel olarak farklı bulundu. Sonuç: Fraktal analiz yöntemi, ortodontik tedavi gören hastaların radyografilerinde oluşan minimal değişikliklerin teşhisini kolaylaştıran ve hastalığın seyrini değerlendiren bir tekniktir. Farklı maloklüzyon gruplarına uygulanan ortodontik tedavi ile mandibular kondil başı kemik oluşumu arasında ilişki bulunabilece...

Background: Craniofacial growth-development has a complex and multifactorial structure. According to functional matrix theory, soft tissues change the development direction of hard tissues and affect the sinus cavities within the cranial structure. The objective of this study is to determine the change in the maxillary sinus dimensions after orthodontic treatments according to malocclusion groups. Methods: Our study comprises 51 individuals who have met the admission criteria. Our study was carried out retrospectively. The individuals included in the study have been analyzed in terms of malocclusion groups by comparing their maxillary sinus dimensions on panoramic films. Results: The intended base length, planar length of the maxillary sinus, and the area measurements of the maxillary sinus have been found to be different at pre-treatment and post-treatment in terms of malocclusion. In Class I, the post-treatment maxillary sinus indentation base length has decreased, and the average planar base length and the maxillary sinus area has increased, and in Class II, the post-treatment maxillary sinus indentation base length and the average planar base length has increased, the maxillary sinus area has decreased, and in Class III, The post-treatment maxillary sinus indentation base length and the average planar base length has decreased, and the maxillary sinus area has increased compared to the pre-treatment. Conclusion: There have been changes in the sinus dimensions of Class I, II, and Class III patients who have received orthodontic treatment compared to the pre-treatment. The changes in the possible craniofacial structures before orthodontic treatments should be taken into consideration carefully, and the dental treatments to be applied should be decided after such considerations.
