Özet:

 This study aimed to compare soft tissue measurements derived from different imaging methodslateral cephalometric radiographs, profile photographs, and three-dimensional 3D stereophotogrammetry 3dMD to evaluate the accuracy and consistency in orthodontic analysis. Thirty-four patients with no craniofacial deformities or a history of trauma were selected. Lateral cephalometric images were analyzed using WebCeph, profile photographs using GIMP, and 3D images with 3dMD Vultus software. Measurements included the nasolabial angle NLA, labiomental angle LMA, and facial convexity angle Conv-A, as well as linear measurements obtained from 3dMD Vultus and WebCeph images. Intra- and inter-rater reliability were assessed using the Intraclass Correlation Coefficient ICC. ANOVA and post hoc tests revealed that NLA values measured with 3dMD were significantly higher than those obtained with other methods p0.05. No significant differences were found in LMA values, while Conv-A measurements showed a statistically significant difference between GIMP and WebCeph p0.05. Linear measurements between WebCeph and 3dMD showed strong agreement ICC0.85. In conclusion, although two-dimensional 2D methods provide clinically acceptable measurements, 3D stereophotogrammetry offers higher accuracy, particularly for critical soft tissue analyses. Based on these findings, it can be concluded that 3D imaging techniques were recommended for orthodontic and maxillofacial studies requiring precise soft tissue evaluation. Based on these findings, the null hypothesis regarding the nasolabial angle was rejected, while the hypotheses for the other angular and linear measurements were accepted.

 Bu çalışma, ortodontik analizlerde doğruluk ve tutarlılığı değerlendirmek amacıyla, lateral sefalometrik radyografiler, profil fotoğrafları ve 3B stereofotogrametri 3dMD ile elde edilen yumuşak doku ölçümlerini karşılaştırmayı amaçlamaktadır. Kraniyofasiyal deformite veya travma öyküsü bulunmayan 34 hasta seçilmiştir. Lateral sefalometrik görüntüler WebCeph, profil fotoğrafları GIMP ve 3B görüntüler 3dMD Vultus yazılımında analiz edilmiştir. Nazolabial açı NLA, labiomental açı LMA ve yüz konveksite açısı Conv-A ölçülmüş, ayrıca 3dMD Vultus ve WebCephte doğrusal ölçümler yapılmıştır. İntra- ve inter-rater güvenilirliği, Sınıf İçi Korelasyon Katsayısı ICC ile değerlendirilmiştir. ANOVA ve post hoc testleri ile yapılan analizlerde, 3dMDde ölçülen NLA değerleri diğer yöntemlerden anlamlı derecede yüksek bulunmuştur p0.05. LMA değerleri arasında fark saptanmamış, Conv-A değerleri GIMP ve WebCeph arasında farklılık göstermiştir p0.05. WebCeph ve 3dMD arasındaki doğrusal ölçümler yüksek uyum sergilemiştir ICC0.85. Sonuç olarak, 2B yöntemler klinik olarak kabul edilebilir olsa da 3B stereofotogrametri, kritik yumuşak doku analizlerinde daha yüksek doğruluk sağlamaktadır.
