Background: Anterior hyperfunction syndrome is when an edentulous maxilla is opposed by natural mandibular anterior teeth. This leads to various complications in patients requiring denture. The present study was conducted to analyze the cases of anterior hyperfunction syndrome in study population. Materials & Methods: This study was conducted on 80 patients having edentulous maxilla wearing maxillary denture and partially edentulous mandible wearing mandibular removable partial denture. They were analyzed for various signs and symptoms seen in patients with anterior hyperfunction syndrome. Results: Maximum cases were recorded for lack of maxillary denture adaptation (male- 12, female- 8). The need for replacement for maxillary denture was seen 5 males and 4 females. Growth of the tuberoisities was seen in 4 males and 5 females. Lack of mandibular denture adaptation was seen in 7 males and 3 females. Need for replacement for mandibular denture was seen in 6 males and 2 females. Papillary hyperplasia was seen in 1 male and 1 female. Hypermobility of the anterior part of the maxilla was seen in females (7) and males (3). Extrusion of lower anterior teeth was seen in 3 males and 2 females. The difference was significant (0.01). Conclusion: The prevalence rate of combination syndrome was 30% with slight male predominance. Most common sign was lack of maxillary denture adaptation and the need for replacement for maxillary denture.
