Abstract
INTRODUCTION: A conventional ortho-surgical treatment, although with good clinical results, does not often achieve the desired functional outcomes. Patients with dentofacial deformities, especially those with increased occlusal planes (OP), are also affected by muscle, joint and breathing functional disorders, as well as facial esthetic involvement. The surgical manipulation of the OP in orthognathic surgery is an alternative to overcome the limitations of conventional treatment. OBJECTIVE: To report the importance of assessing the occlusal plane during diagnosis, planning and ortho-surgical treatment of patients with facial skeletal deformities and its main advantages. CONCLUSION: Although both philosophies of ortho-surgical treatment (conventional and by surgical manipulation of the OP) have presented good results, the selective correction of the OP allows a full treatment of these patients, providing better esthetic and functional results.
Highlights
A conventional ortho-surgical treatment, with good clinical results, does not often achieve the desired functional outcomes
The occlusal plane is the angle between the Frankfurt horizontal plane and a line touching the cusps of premolars and second molars
An increased occlusal plane usually is associated with an open mandibular plane, which occurs in cases of decreased occlusal planes and closed mandibular planes.[1]
Summary
A conventional ortho-surgical treatment, with good clinical results, does not often achieve the desired functional outcomes. The surgical manipulation of the OP in orthognathic surgery is an alternative to overcome the limitations of conventional treatment. Objective: To report the importance of assessing the occlusal plane during diagnosis, planning and ortho-surgical treatment of patients with facial skeletal deformities and its main advantages. Os pacientes com deformidades dentofaciais, principalmente os que possuem plano oclusal (PO) aumentado, são acometidos também por distúrbios funcionais musculares, articulares e respiratórios, além do comprometimento estético facial. Objetivo: relatar a importância da avaliação do plano oclusal nas fases de diagnóstico, planejamento e tratamento ortocirúrgico de pacientes com deformidades esqueléticas faciais, e suas principais vantagens. Conclusão: apesar de ambas as filosofias de tratamento ortocirúrgico (convencional e pela manipulação cirúrgica do PO) apresentarem bons resultados, a correção seletiva do PO permite um tratamento integral desses pacientes, propiciando melhores resultados estéticos e funcionais. » Os pacientes que aparecem no presente artigo autorizaram previamente a publicação de suas fotografias faciais e intrabucais
