high-tech comfort & Care

These X-rays provide us with detailed images of a patient’s smile, allowing us to accurately diagnose issues and create a customized treatment plan.

Precision Bracket Placement

Precision Bracket Placement is a technique that leverages advanced computer software to plan the exact position of each bracket on a patient’s teeth.

With our in-house lab, we can fabricate your retainers right here in our office, which allows for a better fit and faster fabrication of appliances.
