Abstract


Introduction: In cases of accentuated alveolar ridge resorption, the actions that the orofacial muscles have on the basal bone area become more evident, underlining the effects that the contractile action of the muscle fibers produces on the different border zones. Therefore, the complete denture must be well fitted to the basal bone area, respecting the anatomic structures that are directly or indirectly involved.
Objective: To review the literature about the interrelation between anatomy and complete dentures, focusing on the action of the paraprosthetic musculature on these prostheses, and to evaluate the main requirements for their stability and retention.
Method: For this study were used OldMedline and Medline databases from 1942 to 2007, crossing the terms complete denture, anatomy and stability. The BBO database was also used, crossing the terms complete denture and anatomy, between 1985 and 2007. After reading the titles and abstracts, the articles that did not demonstrate the relationship between anatomic structures and complete dentures were excluded. In this way, from the 78 articles retrieved from the initial search, 30 were chosen. Brazilian and international books were also consulted.
Conclusion: The data available in the literature show that that several orofacial anatomic structures present a direct relationship with the complete dentures, in such a way that these structures may affect the stability, retention and functional characteristics of the prostheses. It is therefore important not only to recognize the paraprosthetic structures, but also to know how to identify their role, the type of movements they perform and how they relate to other structures.
