Orthodontic Retainers

We use a state of the art intraoral scanner to create a 3D model of your teeth, from which our lab fabricates retainers and appliances that help maintain your smile after braces or clear aligner treatment. Wearing retainers as prescribed by Dr. Hack or Dr. O’Leary is crucial to prevent teeth from shifting back to their original positions.

Keep your beautiful, healthy smile aligned for life!

I was ready for phase 2 treatment when I was in 8th grade and instead of braces I asked for clear aligners. I’m a senior now and I’m still happy with my smile. The doctors and staff are supportive and personable. I am very happy with my result and am so glad I chose OASECT!!
