The Evans Expander is a product of the dedicated work on mixed-dentition expansion, created by Dr. Marianna Evans. This design features a structured mix of 3D bands and lingual support pads to provide optimal anchorage to the teeth throughout expansion. The addition of buccal bumps ensure a streamlined seating and/or removal process.  The acrylic pad, available in a variety of colors, is split to allow for transverse expansion, and offers additional anchorage and support for teeth throughout the expansion process. Available on the upper arch with acrylic, or on the lower arch in a full-metal design.
