Correct answer: D — An occlusal scheme where the canine tooth disoccludates the posterior teeth during lateral excursion in RPD patients

Canine rise (canine guidance) in RPD design refers to incorporating an occlusal scheme where the canine teeth guide lateral excursive movements, disoccluding the posterior teeth and RPD denture teeth. This reduces lateral forces on distal extension RPD bases and abutment teeth, improving stability and reducing damaging horizontal forces. It is particularly important in Kennedy Class I and II RPDs where the distal extension base is tissue-supported.
