Which term refers to a specific pattern of bone resorption associated with full maxillary dentures opposing only mandibular anterior teeth?

• A. Ridge remodeling syndrome
• B. Mandibular resorption syndrome
• C. Combination syndrome
• D. Maxillary ridge syndrome

Answer: (C)

Combination syndrome describes the specific pattern of bone and tissue changes that occurs when a complete upper denture opposes only the mandibular anterior teeth. The occlusal imbalance produces a characteristic sequence: rapid resorption of the anterior maxillary ridge under the denture, compensatory overgrowth (hypertrophy) of the maxillary tuberosities, extrusion of the mandibular anterior teeth due to lack of posterior contact, and resorption of the posterior mandible where the denture base sits. Papillary hyperplasia of the palate can also be present. This combination of anterior maxillary loss with posterior changes and mandibular anterior extrusion is what makes this pattern distinct. Other terms like ridge remodeling, mandibular-only resorption, or maxillary ridge syndromes don’t capture this specific sequence.
