Abstract

Aim: Selection of an appropriate archwire form is critical for maintaining the natural dental arch and ensuring post-treatment stability. Preformed copper-nickel-titanium (CuNiTi) archwires are widely used in contemporary orthodontics and are often designed with broader arch forms. This study aimed to determine the average mandibular dental arch dimensions to compare them with those of preformed CuNiTi archwires. Materials and Methods: Three-dimensional intraoral scans of 44 individuals with untreated class I malocclusion and minimal crowding/diastema were evaluated. Mandibular intercanine and intermolar widths, as well as canine and molar arch depths, were measured using a bracket slot point-based reference system. Eleven commonly used preformed CuNiTi archwires from five manufacturers were selected, and their corresponding dimensions were measured. Differences between individual dental arch measurements and corresponding archwire dimensions were analyzed using one-sample t-tests, with p < 0.05 as the level of statistical significance. Results: All evaluated preformed CuNiTi archwires differed significantly from the natural mandibular intercanine width (p <0.05). In the intermolar region, Cu Nitanium ProForm – Lower, Cu Nitanium DL-X - Universal, and Tanzo Mid Form III archwires showed no significant difference from the natural mandibular width (p > 0.05), whereas the remaining archwires demonstrated significant discrepancies. Conclusion: None of the evaluated archwires matched the intercanine width, and limited compatibility was observed in the intermolar region. These findings suggest that dimensional discrepancies are mainly concentrated in the intercanine region, emphasizing the importance of individualized archwire selection to preserve mandibular arch stability.

Özet

Amaç: Uygun ark teli formunun seçimi, doğal dental arkın korunması ve tedavi sonrası stabilitenin sağlanması açısından kritik öneme sahiptir. Önceden şekillendirilmiş bakır-nikel-titanyum (CuNiTi) ark telleri güncel ortodontik uygulamalarda yaygın olarak kullanılmakta ve çoğunlukla daha geniş ark formlarına sahip olacak şekilde üretilmektedir. Bu çalışmanın amacı, ortalama mandibular dental ark boyutlarını belirlemek ve bunları önceden şekillendirilmiş CuNiTi ark telleri ile karşılaştırmaktır. Gereç ve Yöntemler: Minimal çapraşıklık veya diastemaya sahip, tedavi görmemiş Sınıf I maloklüzyonlu 44 bireyin üç boyutlu intraoral taramaları değerlendirildi. Mandibular interkanin ve intermolar genişlikler ile kanin ve molar ark derinlikleri, braket slot noktasına dayalı referans sistemi kullanılarak ölçüldü. Beş farklı üreticiye ait yaygın olarak kullanılan 11 adet önceden şekillendirilmiş CuNiTi ark telinin boyutları kaydedildi. Bireysel dental ark ölçümleri ile önceden şekillendirilmiş ark teli boyutları arasındaki farklar tek örneklem t-testi ile analiz edildi ve istatistiksel anlamlılık düzeyi p < 0.05 olarak kabul edildi. Bulgular: Değerlendirilen tüm önceden şekillendirilmiş CuNiTi ark telleri, doğal mandibular interkanin genişlikten anlamlı düzeyde farklı bulundu (p < 0.05). İntermolar bölgede ise Cu Nitanium ProForm - Lower, Cu Nitanium DL-X - Universal ve Tanzo Mid Form III ark telleri doğal mandibular genişlikten anlamlı fark göstermedi (p > 0.05); diğer ark tellerinde anlamlı farklılık saptandı. Sonuç: Değerlendirilen ark tellerinin hiçbiri doğal interkanin genişlik ile uyum göstermemiş, intermolar bölgede ise sınırlı düzeyde uyumluluk gözlenmiştir. Bu bulgular, boyutsal uyumsuzlukların ağırlıklı olarak interkanin bölgede yoğunlaştığını göstermekte ve mandibular ark stabilitesinin korunması için bireyselleştirilmiş ark teli seçiminin önemini vurgulamaktadır.
