Treatment in the Spotlight

Dr. S. Shih-Hsuan Chen

We would like to thank Dr. Chen for this great case that achieved all treatment goals for her patient including resolution of midline deviation and crowding.

 

Dr. Quote: "Many smiles are being covered under masks during the COVID-19 pandemic. Fortunately, Invisalign aligners can continue to transform patients' smiles even while they stay at home. Stay safe."
