Cambios cefalométricos en pacientes con prognatismo y pseudo prognatismo mandibular pre y postquirúrgicos.

Abstract

Introduction: Class III malocclusion is considered the third oral health problem after caries and periodontal disease, according to the WHO. Dental class III is related to mandibular prognathism, which is characterized by a mandible with vertical growth. For this reason, it is necessary to make an early diagnosis of the eruption of the first permanent molars and canines, which determine the key to occlusion. The treatments can be interceptive using functional orthopedics and corrective with orthodontic-surgical treatment. Objective: To determine the cephalometric changes in patients with mandibular prognathism and pseudo prognathism pre and post-surgery. Materials and Methods: It is a systematic review in which metasearch engines such as: Google Scholar, Pubmed, Scielo, Medline were used, and the result yielded 40 important research articles for this work. Results: Mandibular pseudoprognathism is the product of multifactorial alterations that influence dentoskeletal development, which must be corrected early with functional orthopedics and orthosurgically after calcification of the bone growth centers. The diagnosis must be clinical and radiographic, making a cephalometric analysis considering mainly the ANB angle. Conclusion: Pseudoclass III disharmony tends to worsen with growth, so early orthodontic intervention is necessary to prevent true prognathism before growth of the craniofacial skeletal sutures is complete.
