Expansão rápida da maxila em paciente portador de fissura transforame incisivo unilateral: caso clínico

Abstract

The performance of maxillary expansion is extremely important during the treatment of a patient with a cleft. The unilateral transforamus incisor cleft is the most common variant among oral clefts, impairing maxillary development, compromising facial function and aesthetics. The objective of this work is to evaluate the effects of rapid maxillary expansion using the Haas expander and to quantify the changes in the measurements. The case was performed on the patient K.B.O.P, aged 11, who sought care at Sociedade Especializada em Atendimento ao Paciente Fissurado do Estado de Sergipe (SEAFESE) during the period of one year. Among the results, we observed that after rapid maxillary expansion, there was an immediate and significant change in the transverse, vertical and anteroposterior direction of the maxilla, both in the anterior and posterior areas, demonstrating the effectiveness of the rapid expansion method and the Haas expansor in cases of fissure.
