Three-dimensional assessment of transverse displacement with Facemask and Maxgym in unilateral cleft lip and palate model.
Growing patients with cleft lip and palate (CLP) exhibit maxillary deficiency due to early surgical intervention. Maxillary protraction with expansion is the recommended treatment modality for deficient maxilla. Facemask is a conventional protraction appliance, and Maxgym is a new protraction appliance. The purpose of this study is to compare the efficacy of Maxgym with Facemask using finite-element analysis. ⋯ Maxgym forces produce greater transverse displacement as compared to facemask with or without expansion.
