How does the coronoid process affect the maxillary denture?
Show answer and explanation
Correct answer: B. It limits the buccal flange extension during function.
The coronoid process plays an important role in the functional movements of the maxillary denture. During wide opening or lateral movements of the mandible, the coronoid process may come into contact with the posterior buccal flange of the maxillary denture. This limits the extension of the buccal flange in that region to avoid interference. If the buccal flange is overextended, it can cause discomfort and instability of the denture. Therefore, careful consideration is needed during the fabrication process to ensure proper function without interference.
