Correlazione tra malocclusione di Classe II e problematiche articolari : revisione della letteratura

Objectives: The purpose of this literature review is to evaluate current knowledge about the relationship between Angle Class II malocclusion (especially the second division) with temporomandibular dysfunction (TMD). Materials and methods: A survey has been conducted through the electronic databases Medline, using specific inclusion and exclusion criteria, keywords " temporomandibular disorder AND malocclusion class II". Of the 252 articles resulting from research 23 have been selected that met all the inclusion criteria of this review. Results: The prospective, longitudinal and retrospective analysis does not ultimately support a primary role of occlusion, especially Class II malocclusion second division, in the development of joint problems and also support the hypothesis of a multifactorial origin theory of joint problems. Conclusions: It is therefore impossible to make any provision of proper development of TMD on the basis of the presence or absence of a malocclusion although in some studies the Class II malocclusion has been associated with a higher prevalence of muscle strains problems. So, while there is a clear lack of association with joint issues closely (click, lock joint, dislocations) Class II malocclusion in the literature is related only to problems of muscular type.
