Ortodontik tedavi görmüş hastalarda implant planlaması öncesinde fraktal analiz yöntemi kullanılarak alveolar trabeküler kemik yapısının tayini

Amaç: Bu çalışmanın amacı, ortodontik tedavi gören hastaların implant tedavisinde rehber olması amacıyla, ortodontik tedavi öncesinde (T0), hemen sonrasında (T1) ve 6 ay sonrasında (T2) trabeküler kemik değişikliklerini fraktal boyut (FD) analizini kullanarak değerlendirmektir.Gereç ve Yöntemler: Çalışmaya bir dişi eksik olan toplam 32 ortodonti hastası dahil edildi. Hastalar dişleri hizalamak ve implant yerleştirmek için boyutsal olarak uygun bir alan oluşturmak için tedavi edildi. Panoramik radyografiler standart protokollerle sabit ortodontik tedavi öncesinde (T0), hemen sonrasında (T1) ve 6 ay sonrasında (T2) alındı. FD analizi Image J 1.3 yazılımı kullanılarak kutu sayma yöntemiyle yapıldı. Bulgular: En yüksek FD değeri tedavi öncesinde ölçüldü (T0 = 1.47 ± 0.14). T2' nin ortalama FD değeri (1.32 ± 0.14), T1'den (1.19 ± 0.15) istatistiksel olarak anlamlı derecede yüksek bulundu (p <0.001). Sonuç: Trabeküler kemik zamanla daha karmaşık bir yapı kazandığından, ortodontik tedavinin sona ermesinden hemen sonra implant ameliyatı planlanmaması önerilmektedir. FD analizi kemik trabekül yapısını panoramik radyografilerde incelemek için basit ve uygun maliyetli bir yöntemdir.

Estimation of the trabecular structure of alveolar bone before implant planning in orthodontic treated patients by using fractal analysis method

Background:The aim of this study was to assess the trabecular bone pattern changes of orthodontically treated patients before orthodontic treatment (T0), immediately after (T1) and 6 months after (T2) the treatment by using fractal dimension (FD) analysis in order to guide implant applications. Methods:Totally 32 orthodontic patients who had one missing tooth were included in the study. Patients were treated to align the teeth and to create a dimensionally appropriate space for implant placement. Panoramic radiographs were taken with standard protocols at the time periods of before (T0), immediately after (T1) and 6 months after (T2) treatment. FD analysis was performed using Image J 1.3 software with the box-counting method. Results:The highest FD value measured before treatment (T0=1.47±0.14). Mean FD values of T2 was found statistically significantly higher (1.32±0.14) than T1 (1.19±0.15) (p<0.001). Conclusions:It is suggested not to plan implant surgery immediately after the end of orthodontic treatment because trabecular bone gains more complex nature over time. FD analysis is a simple and cost-effective tool for examining bone structure in panoramic radiographs.
