Abstract

Objective: This study aimed to
evaluate the stability of transversal arch widths of upper and lower dental
arches following retention with thermoplastic retainers applied after non-extraction
fixed orthodontic treatment.

Materials and
Method:
The material consisted of the pre-treatment (T1), post-treatment
(T2) and post-retention (T3) cephalometric data and the dental models of 21
patients (16 female, 5 male;
average age 17.5 ± 1.2 years), who presented
skeletal Class 1 and dental Angle class I relationship with an optimal vertical
facial pattern, and small amount of crowding in both jaws. The patients had
been treated by non-extraction fixed orthodontic treatment followed by the
application of thermoplastic retainer with a mean retention period of 1 year. The
dental models were scanned and transferred to digital environment to measure
inter-canine, inter-premolar and inter-molar widths for both dental arches.
Repeated Measures ANOVA and Wilcoxon Signed-Rank tests were used for the
statistical analysis of the data having normal and non-normal distribution,
respectively (
α=0.05).

Results: Statistically
significant differences were found in the upper inter-premolar width between
the T1-T2 periods
(p<0.001), and between the T1-T3 periods (p<0.001), and in the lower inter-premolar
width, between the T1-T2 periods only
(p<0.001). In none of the
arches and for none of the parameters a statistically significant difference
was found between the
T2-T3 periods (p>0.05).







Conclusion:
Retention
with thermoplastic retainers was found to be effective in maintaining
transversal arch width in both arches after non-extraction fixed orthodontic
treatment.

Abstract

Amaç: Çekimsiz sabit ortodontik tedavi görmüş hastalarda
termoplastik apareyler ile yürütülen pekiştirme tedavisi sonunda alt ve üst
dental arklardaki transversal boyutların stabilitesinin değerlendirilmesi
amaçlandı.

Gereç ve Yöntem: Çekimsiz sabit ortodontik tedavisi tamamlanmış ve termoplastik
aparey ile ortalama 1 yıllık pekiştirme dönemi kayıtları mevcut olan iskeletsel
Sınıf 1, dişsel Angle sınıf I, optimal dik yön büyüme paterni gösteren, alt ve
üst arkta hafif çapraşıklığı bulunan 21 hastanın (16 kız, 5 erkek;
yaş ortalaması 17.5 ± 1.2 yıl) tedavi başı (T1), tedavi sonu
(T2) ve pekiştirme sonu (T3) lateral sefalometrik kayıtları ile dental modelleri
değerlendirmeye alındı. Dental modeller, masaüstü tarayıcı ile taranarak
dijital ortama aktarıldı. İnterkanin, interpremolar ve intermolar mesafeler her
iki çenede ölçüldü. İstatistiksel olarak, normal dağılım gösteren veriler Tekrarlı
Ölçümler İçin ANOVA testi ile, normal dağılım göstermeyen veriler ise Wilcoxon
Signed-Rank testi ile değerlendirildi (
α=0.05).

Bulgular: İstatistiksel olarak anlamlı farklar üst çenede interpremolar
mesafe için T1-T2 dönemleri arasında (p<0.001) ve T1-T3 dönemleri arasında (p<0.001),
alt çenede ise interpremolar mesafe için yalnızca T1-T2 dönemleri arasında bulundu
(p<0.001). Hiçbir çenede, hiçbir parametre için T2-T3 dönemleri arasında
istatistiksel olarak anlamlı fark bulunmadı (p>0.05).







Sonuç: Termoplastik
apareylerin çekimsiz sabit ortodontik tedavinin pekiştirme dönemi sonunda
transversal yöndeki tedavi sonuçlarını koruduğu bulundu.
