About Us

Families in Montgomery and Sandwich, Illinois, and in the nearby areas of Aurora, Oswego, and Yorkville, have access to an outstanding orthodontic resource in Kay & Cortopassi Orthodontics. Under the leadership of C. Neil Kay, BDS, MS, and Dr. Chris Cortopassi D.M.D. M.S. the practice has earned a reputation for excellence in the region, and has improved the smiles of people of all ages.

Top-quality orthodontics requires a dedication to customized care. Everyone’s smile is unique, and focusing on the specific needs and treatment goals of each patient allows the Kay & Cortopassi Orthodontics team to deliver amazing outcomes.

While the practice recruits some of the best dental support professionals in the area, braces and wires are always placed by the doctors, not dental assistants or technicians. When new patients come to the practice, they meet one-on-one with an orthodontist to discuss how orthodontia can help improve the appearance and function of their teeth.

Conservative care is a foundational principle of Kay & Cortopassi Orthodontics. There are no treatment coordinators to deliver a sales pitch, and no pressure to sign on for treatment that is unnecessary. Patients learn about all available treatment options and understand the full price of care before making a treatment decision.

The practice uses the very best dental tools and technology to perform orthodontic services, including InvisalignⓇ. Kay & Cortopassi Orthodontics is one of the largest providers in the country for the Spark™ Clear Aligner System, an innovative teeth alignment approach and an alternative to traditional metal braces. Damon SystemⓇ braces are also available, and can deliver faster results than other orthodontic options.

Diagnostic services are performed using the VatechⓇ Green CBCT digital imaging system. This technology creates outstanding imaging using an ultra-low X-ray dose, which is safer for both patients and staff. The iTeroⓇ Element intraoral scanner creates high-resolution imaging that allows patients and orthodontists to visualize a smile both before and after treatment.

If you’re considering orthodontic services for yourself or your child, request an appointment online or call the Kay & Cortopassi Orthodontics office nearest you. .
