Select what is the most often malocclusion.

• A. malocclusion of the II/II Angle class
• B. deep bite
• C. malocclusion of the II/I Angle class
• D. crossbite occlusion

Answer: (C)

Understanding how molar and canine relationships relate in Angle’s classification helps explain why this pattern is most often seen. In practice, many patients present with a posterior misalignment where the upper and lower first molars show a Class II relationship, but the canines still bite together in a Class I pattern. This combination—molar Class II with canine Class I—is a very common presentation because the posterior segment often shifts or crowds due to space issues or jaw growth patterns, while the anterior segment can remain relatively well-aligned (or compensate) so the canine relationship stays Class I. That's why this II/I configuration is encountered more frequently than when both molars and canines are Class II, or when a crossbite or deep bite is the dominant issue.
