Hybrid Invisalign + Braces Plan
At 303 Smiles, you don’t have to pick between metal brackets and clear aligners—or even stick with one the entire time. Dr. Straffon builds a flexible plan where braces and Invisalign work together in whichever order makes the most sense for your smile. Sometimes, we kick things off with clear aligners; other times, braces take the first turn. Each phase uses the appliance that moves your teeth the quickest and keeps life simple.

- Wrap up sooner – we start with the appliance that delivers the biggest changes fast
- Stay motivated – switching appliances midway keeps treatment fresh
- Less appliance fatigue – fewer total months wearing any one device
- Precision and freedom – braces handle complex moves; aligners add eat-what-you-want convenience
- Comfort counts – smooth aligners or low-profile brackets, selected at the right time for your comfort
- Smiles that wow – patients and parents rave about the finished results
- Planned to a T – every step is mapped out by Dr. Straffon for your lifestyle and goals
How it Works
Step One: We begin with either braces or Invisalign—whichever works better for your bite.
Step Two: Once the first phase has completed its task, we proceed to the next appliance to refine every detail.
SStep Three: Complete your treatment, insert your retainers, and keep that confident smile for life.
