Maxillary facial and mandibular lingual cusps require sufficient occclusal length and horizontal overlap for_____________?
Correct answer: D. Soft tissue protection
- A. Esthetics
- B. Centric stability
- C. Chewing efficiency
- D. Soft tissue protection
Explanation
The maxillary buccal and mandibular lingual cusps form the outer protective components of the occlusion, shielding the cheeks and tongue from being caught between the teeth. Their length and horizontal overlap are therefore important for soft-tissue protection.
