Abstract

Aim: The aim of this study was to evaluate the role of the Bonwill triangle in temporomandibular disorders (TMDs).
Materials and Method: This study was conducted using 1880 cone beam computed tomography (CBCT) images obtained from the Department of Oral, Dental, and Maxillofacial Radiology Clinic at Nuh Naci Yazgan University Faculty of Dentistry between June 2020 and February 2024.
Results: A total of 154 patients were included in the study, with ages ranging from 18 to 45 years (mean age: 24.9 ± 5.8 years). Of these, 70 were male (45.5%), and 84 were female(63.0%). The control and TMD groups each comprised 77 patients. In the analyses, no statistically significant difference in the measurements examined was found between the TMD and control groups (p>0.05). In males, the distance between the center of the right condyle and the center of the right mandible (IC-R) was
found to be significantly higher compared to females (p<0.001). Similarly, the distance between the center of the left condyle and the center of the left mandible (IC-L) was found to be significantly higher in males than in females (p<0.001). Additionally, the intercondylar distance measurement was found to be significantly higher in males compared to females(p<0.001). However, there was no statistically significant difference in the IC-R (right and left) and intercondylar distance measurement between the control and
TMD groups (p>0.05).
Conclusion: Limited information exists in the literature about the impact of the Bonwill triangle on TMD. Our findings suggested that TMD did not have a significant effect on these anatomical features. However, gender was found to have a significant effect. These results underscore the need for further research to develop a more comprehensive understanding of the pathophysiology of and treatment strategies for TMD.

Temporomandibular Bozukluklarda Bonwill Üçgeninin Rolünün Değerlendirilmesi: Retrospektif Analiz

Abstract

Amaç: Bu çalışmanın amacı, Bonwill üçgeninin temporomandibular bozukluklar (TMB) üzerindeki etkisini değerlendirmektir.
Gereç ve Yöntem: Nuh Naci Yazgan Üniversitesi Diş Hekimliği Fakültesi’nde Haziran 2020 ile Şubat 2024 tarihleri arasında elde edilen 1880 konik ışın bilgisayarlı tomografi (KIBT) görüntüsü kullanılarak bu çalışma yürütülmüştür.
Bulgular: Çalışmada, toplam 154 hasta incelenmiştir, yaşları 18 ila 45 arasında değişmekte olup ortalama yaşları 24.9 ± 5.8’dir. Bu hastaların 70’i erkek (%45.5) ve 97’si kadındır (%63.0). Kontrol grubunda 77 hasta bulunurken, TMD tanısı alan grubunda da 77 hasta bulunmaktadır. Yapılan analizlerde, TMD grubu ile kontrol grubu arasında incelenen ölçümlerde istatistiksel olarak anlamlı bir farklılık bulunmamıştır (p>0.05). Erkeklerde, sağ kondilin merkezi ile sağ mandibular merkez arasındaki mesafe (IC-S) kadınlara göre istatistiksel olarak anlamlı derecede yüksektir (p<0.001). Benzer şekilde, sol kondilin merkezi ile sol mandibular merkez arasındaki mesafe (IC-S) erkeklerde kadınlara göre anlamlı derecede yüksektir
(p<0.001). Ayrıca, interkondiler mesafe ölçümü erkeklerde kadınlara göre anlamlı derecede yüksektir (p<0.001). Kontrol grubu ile TMD grubu arasında ise IC-S (sağ ve sol) ve interkondiler mesafe ölçümlerinde istatistiksel olarak anlamlı bir farklılık bulunmamıştır (p>0.05)
Sonuç: Bonwill üçgeninin TMD üzerindeki etkisi hakkında literatürde sınırlı bilgi bulunmaktadır. Bu çalışmanın sonuçları, TMD’nin bu anatomik özellikler üzerinde belirgin bir etkisi olmadığını göstermektedir. Ancak cinsiyetin bu ölçümler üzerinde belirgin bir etkisi olduğu bulunmuştur. Bu bulgular, TMD’nin
patofizyolojisi ve tedavi stratejileri üzerine daha derinlemesine bir anlayış geliştirmek için daha fazla araştırmanın gerekliliğini vurgulamaktadır.
