“Clinical comparison of bond failure rate between two types of mandibular canine-canine bonded orthodontic retainers- a randomized clinical trial”
Abstract Background Bonded retainers are widely used as they are esthetically pleasing, easily acceptable, provide greater stability, compliance free and causes no soft tissue irritation and speech problems. Though, fracture and bond failure are their shortcomings. Therefore, the objectives of this...

The bond failure rate and failure pattern were compared between the two retainers by using Chi-square test. Results The bond failure rates were 42.94% for FRC retainer and 31.41% for MSW retainer.
