Abstract

Peranti lepasan merupakan bagian dari perawatan ortodonti. Pegas kantilever tunggal merupakan komponen aktif dari peranti lepasan yang mengerakan gigi kearah mesial-distal. Daya lenting secara klinis memberikan gaya yang konstan selama pergerakan gigi. Posisi koil terhadap basis akrilik, diameter kawat, diameter koil, dan perubahan suhu mempengaruhi besar daya lenting. Menambah koil dapat memperpanjang kawat dan meningkatkan daya lenting yang dihasilkan. Daya yang dibutuhkan untuk menggerakkan gigi berakar tunggal adalah 25-40 gram. Tujuan: Untuk mengetahui perbedaan daya lenting pegas kantilever tunggal dengan posisi koil dan diameter koil. Metode: Penelitian yang digunakan yakni pre eksperimental. Penelitian ini adalah penelitian eksperimen yang memanipulasi independent variable, pemilihan subjek penenlitian dilakukan secara non random, dan tidak memiliki control grup atau comparison group. 45 sampel dibagi menjadi 9 kelompok dengan posisi koil 9 mm, 12 mm dan 15 mm dari basis akrilik dan diameter koil 2 mm, 2,5 mm, dan 3 mm. Kantilever tunggal diaktivasi sebesar 3mm. Pengujian pengukuran daya lenting menggunakan Gauge Meter. Hasil: Uji One Way ANOVA menunjukkan terdapat perbedaan daya lenting kantilever tunggal dengan posisi koil dan diameter koil (sig<0,05). Uji Post Hoc Turkey membuktikan terdapat perbedaan bermakna antara posisi koil dan diameter koil (sig<0,05). Hasil penelitian menunjukkan bahwa semakin besar diameter koil maka semakin kecil daya lenting yang dihasilkan, sedangkan semakin jauh posisi koil maka semakin besar daya lenting yang dihasilkan. Kesimpulan: Perbedaan posisi koil dan diameter koil berpengaruh terhadap daya lenting yang dihasilkan pada pegas kantilever tunggal.

English Abstract

Background: A removable appliance is part of orthodontic treatment. single cantilever spring is an active component from a removable appliance that moves teeth towards the mesial-distal. The springiness clinically provides a constant force during tooth movement. The distance of the position of the coil to the acrylic base, the diameter of the wire, the diameter of the coil, the cross -sectional area of the wire and the change in temperature affect springiness. Adding coil can extending the wire and increasing the results of springiness. The force required to move a single rooted tooth is 25-40 grams Purpose: To determine the difference in springiness at coil position distance and coil diameter. Method: The research used is pre-experimental. This research is an experimental study that manipulates independent variables, the selection of research subjects is carried out non-randomly, and does not have a control group or comparison group. 45 samples were divided into 9 groups with a coil position distance of 9 mm, 12 mm and 15 mm from the acrylic base and coil diameters of 2 mm, 2.5 mm, and 3 mm. Single cantilever activated by 3mm. The springiness measurement is measured using the Force Gauge Meter. Result: One Way ANOVA test showed that there was in the springiness of a single cantilever with the distance of the coil position and the diameter of the coil (sig < 0.05). The Post Hoc Turkey test proved that there was a significant difference between the the different coil position distance and the different coil diameters (sig < 0.05). The results showed that the larger the diameter of the coil, the smaller the springiness produced, while the farther the coil position distance, the greater the springiness produced. Conclusion: The coil position distance and the coil diameter affects the springiness produced in a single cantilever spring.
