Abstract
A mandibular positioning facial retrognathism orthodontic system and a design method thereof are disclosed. The orthodontic system includes a maxillary shell-like dental appliance having a shell-like body, a protrusion portion protruding toward an opposite jaw is disposed at a posterior area corresponding to the shell-like body, a traction portion is disposed at a labial side of the shell-like body, and a retaining portion configured for fastening with a retaining attachment is disposed at the posterior area corresponding to the shell-like body. The protrusion portion is engaged with the posterior area of a mandibular for occlusal reconstruction, so that mandibular incisors are aligned with maxillary incisors. The design method is a design method for the mandibular positioning facial retrognathism orthodontic system, which can provide a treatment-specific orthodontic system, thereby achieving treatment of mandibular positioning facial retrognathism.
