Advanced Orthodontic Care, Powered by Technology
At Saint Louis South Orthodontics, we use advanced technology such as the iTero® digital scanner to create precise 3D models without traditional impression materials. Invisalign® clear aligners offer a comfortable, removable, and discreet option for straightening your smile.
Invisalign®
Invisalign® straightens teeth using a series of customized, removable, clear aligners designed to gradually improve your smile.
3D Modeling
Instead of traditional impressions, we use digital technology to create accurate 3D models of your teeth for treatment planning.
iTero®
The iTero® digital scanner creates detailed 3D images of your teeth, helping our team plan treatment with greater precision.
“Orthodontics is a dental specialty that is concerned with the study and treatment of malocclusions (improper bites), which may be a result of tooth irregularity, disproportionate jaw relationships, or both. My passion for being an orthodontist and creating artistic smiles is amazingly rewarding as the result of orthodontic treatment restores confidence and self-esteem.”
