What term describes a pattern of bone resorption in the anterior edentulous maxilla when it opposes mandibular anterior teeth only?

• A. Osteoradionecrosis
• B. Residual ridge syndrome
• C. Peri-prosthetic syndrome
• D. Combination syndrome

Answer: (D)

This pattern is combination syndrome, a denture-related sequence of changes that occurs when a maxillary complete denture opposes only mandibular anterior teeth. The anterior maxilla begins to resorb due to the unopposed anterior pressure, while the posterior maxillary region can respond with tuberosity overgrowth. You’ll also see changes such as papillary hyperplasia in the palate, extrusion of the mandibular anterior teeth, and a tendency for loss of posterior occlusion. This combination of signs—especially the rapid resorption of the anterior maxilla in the setting described—defines this condition, making it the best answer. Osteoradionecrosis is radiation-induced bone death, not a denture-induced pattern. Residual ridge syndrome refers to generalized ridge resorption without this specific anterior-maxillary pattern. Peri-prosthetic syndrome describes soft-tissue or peri-implant issues around prostheses, not the characteristic maxillary anterior resorption with tuberosity changes seen here.
