Just as Dr. Leonard is the expert at moving teeth with braces, he is also the expert at moving teeth with Invisalign. When Invisalign was first introduced to the profession, AlignTech (the makers of Invisalign) would only certify orthodontists to use the system. It was not until the company lost a lawsuit brought by a primary care dentist, that AlignTech devised one day seminars to teach primary care dentists how to move teeth with Invisalign. With 5000+ hours of graduate training in orthodontics after graduating near the top of his class in dental school, Dr. Leonard is your go-to guy when it comes to orthodontic treatment. It is similar to the difference between your primary care physician and a cardiologist when it comes to treating heart disease.
