- Aetiology and management of class III malocclusionPublication . Zanforlin, Mariana Baptista; Bugaighis, ImanClass III malocclusion is characterized by a complex three-dimensional facial skeletal disparity between maxillary and mandibular growth patterns along with varying degrees of dentoalveolar and soft tissue compensations. In terms of severity, this malocclusion ranges from dentoalveolar abnormalities or functional anterior mandibular displacement to true skeletal problems with substantial maxillomandibular discrepancies. In addition, this condition can be aggravated by vertical growth problems. Skeletal Class III malocclusions can be a result of retrognathic maxilla with a normal mandible both in position and in size, or prognathic mandible with a normal maxilla both in position and in size or a combination of retrognathic maxilla with prognathic mandible. Although not very prevalent, skeletal Class III malocclusion represents a huge challenge in terms of therapeutic approach and post-treatment stability. Hence, to determine a realistic and appropriate management and the ideal treatment timing, it is essential to establish an accurate diagnosis. Moreover, a thorough understanding of craniofacial growth and development is required to estimate the remaining growth, especially when growth modification is envisioned. The aim of this literature review was to provide an overview of Class III malocclusion, with emphasis on its aetiology and components. Evidence based approach and critical appraisal of the relevant literature in English and Portuguese languages between the years 1899 – 2021 were performed. Several search engines were employed such as Pubmed, google scholar Scielo, B-on, the Cochrane data base and relevant books on the subject. The following keywords were used throughout the research process: Class III malocclusion, aetiology, treatment, mandibular prognathism.
