[HTML][HTML] Survival analysis of an orthodontic bracket bond subjected to cyclic tensile and shear forces
AY Mansour, M Bamashmous - Journal of Orthodontic Science, 2018 - journals.lww.com
OBJECTIVES: The objective of this study was to evaluate the use of survival analysis in
cyclic fatigue testing in orthodontic bracket bonding. MATERIALS AND METHODS: We used
100 extracted bovine lower incisors (50 orthodontic brackets and 50 eyelet brackets). Each
set of brackets was further divided by etching technique (25 total-etch and 25 self-etch).
Cyclic fatigue testing was performed at a crosshead speed of 2 mm/min using an up-and-
down method. Kaplan–Meier survival data analyses and Cox regression analyses were …
