What sets us apart?

Technology & Innovation

The field of orthodontics has made extraordinary advancements in the past decade with the use of space age super-elastic wires, frictionless bracket systems and advancements in aligner systems such as Invisalign and Invisalign Teen. Dr. Cassalia has been at the forefront of this orthodontic revolution. His Wirelign invention has evolved into C5 Hidden Orthodontics, an orthodontic treatment that uses tiny wires that are completely concealed behind the teeth without the use of braces or removable aligners (trays). As a result, our office – in addition to providing traditional orthodontic care – has evolved into a sub-specialty of concealed orthodontic solutions to orthodontic problems for adults and the self-conscious teen.
