I have learned from Dr. Sangiv Patel first hand over many years. His indepth of knowledge of the stomatognatic system is extraordinary. I have used the his protocols in my practice for many years. This has definitely resulted in the longitivity of the restorations and the prostheses I have provided to my patients. Every time I have an opportunity to hear him or take part in one his courses, I definitely learn some more which enhances my knowledge and improves treatment I provide to my patients.
