Clinically Relevant Aspects of Dental Materials Science in Orthodontics - Multiple choice questions In Orthodontics
Test your knowledge on Clinically Relevant Aspects of Dental Materials Science in Orthodontics (Graber 7th Edition) with these 35 high-yield MCQs. 1. The stiffness (elastic modulus) of a stainless steel bracket is clinically most relevant to which mechanic? A. Friction during sliding mechanics B. Bond strength to enamel C. Torque expression D. Corrosion resistance Click to Reveal Answer Correct Answer: C Explanation: Stiffness determines the bracket's resistance to deformation. During torque application with rectangular wires, a bracket with low stiffness may experience elastic deformation (slot widening), which significantly reduces the effective torque delivered to the tooth. 2. Which feature of a stainless steel bracket slot surface has the greatest impact on increasing resistance to sliding (friction)? A. High polish B. Increased s...
