Clear Expansion Plate: A Novel Technique

Abstract Objectives Posterior crossbite is one of the most common orthodontic problems in primary and mixed dentition that induces deleterious and permanent effects on dentition, dentoskeletal structures, and esthetics. Early correction of unilateral and bilateral posterior crossbite is necessary to prevent these problems. Early intervention with removable Schwarz appliance is one of the useful appliances to correct posterior crossbite, but it has its own disadvantages. Materials and Methods In this article, we have presented a new appliance and method of fabrication to aid the expansion of the maxilla. Results The presented “clear expansion plate” that is made by thermoplastic sheets maintains all of the positive properties of the Schwarz plate and has several additional advantages. Conclusion After being tested in clinical trials, traditional expansion plate can be replaced by clear expansion plate.
