Tissue Engineering and Regeneration

We offer several revolutionary and innovative tissue regeneration treatments that use your body’s own natural healing abilities in order to put your oral health in excellent condition and make you a candidate for life-transforming dental implants. We also use stem cell therapy to recapitulate de-novo bone formation to not just repair, but truly regenerate, bone and periodontal tissues back to health.

Surgical Orthodontics

Surgically Facilitated Orthodontic Therapy, or SFOT, uses a modern and safe way to straighten teeth and restore complete oral health. It begins with imaging diagnostics and tooth movement simulation software to understand where teeth need to be positioned for the patients face/smile, bite, and airway. This approach provides novel risk assessment of the available bone around the teeth and highly personalizes an individuals orthodontic plan. When needed, fortifying the jawbone (the foundation of the smile) by SFOT can help transform a vulnerable periodontium away from future gum recession problems and may also help avoid tooth extraction as apart of the orthodontic plan. It can even restore receding gums and gain oral cavity volume for the tongue as apart of the interdisciplinary process.
