In a Kennedy Class II modification 2 RPD, the curve of Spee is typically:
Show answer and explanation
Correct answer: A. Steep
- A. A Kennedy Class II modification 2 describes a unilateral distal extension with two additional edentulous areas elsewhere. The loss of posterior support and multiple edentulous areas leads to supraeruption of opposing teeth and a STEEP curve of Spee, creating occlusal problems for RPD fabrication.
- B. A reverse curve of Spee (anti-Monson) occurs in cross-bite cases — not typical for Class II Mod 2 RPD patients.
- C. An absent (completely flat) curve is not characteristic of Class II mod 2 RPD patients who typically exhibit exaggerated curves.
- D. A flat curve of Spee represents ideal or corrected occlusion — not typical in Class II Mod 2 with multiple missing teeth.
