Abstract

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

Abstract

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.
