Impact of residual ridge anatomy on masticatory efficiency of conventional complete denture users

ABSTRACT Objective: The aim of this cross-sectional study was to evaluate the anatomical characteristics edentulous residual ridges in stone casts complete dentures users and assess correlations with masticatory efficiency. Methods: sample included 74 casts, which 37 were higher bottom. Measurements performed using a drypoint compass transparent ruler. Arches maxillae mandibles classified into small, medium, large. Masticatory efficiency obtained by sieve method old prostheses 3 months after placement new prostheses. between variables arches (height, width size) verified Spearman correlation test. Significant differences efficiencies assessed Wilcoxon Results: People larger maxillary alveolar ridge presented better performance dentures. There no size efficiency, but found arch evaluated Conclusions: With dentures, had tendency for significance. For mandible, height, width, or length, In addition, there significant difference maxilla, height influence anatomy little on performance.
