To correct this malocclusion, there are currently several forms of treatment. Among the functional orthopedic devices, the Herbst device has stood out due to its efficiency and practicality for being fixed and not requiring the collaboration of the patient. The purpose of this article is to present, through a clinical case report, the treatment of class II malocclusion with a modified Herbst appliance with a lower acrylic splint. The female patient initially had 11 years and 11 months, permanent dentition, mandibular retrusion and atresia of the arches. Initially, a maxillary circuit breaker and lower expander were used, followed by the Herbst appliance and finished with fixed orthodontics. At the end of the treatment, the modified Herbst appliance proved to be effective, providing a class I molar relationship, improving the patient’s profile and decreasing the space between the resting lips.
