All-on-4-dental-implants.org Dr. Golpa was among the first Dentists in the U.S. to embrace the All-on-4® procedure, practice it routinely, and perform every aspect of the procedure (planning, placement & delivery), starting in 2005. Through his experience of performing this procedure thousands of times, he realized that improvements and modifications could be made that would benefit the Patient. Performing every aspect of the procedure himself, has given him invaluable insight into the protocol. Dr. Golpa has performed this procedure more than any single Practitioner in the world. He feels that, in most cases, it provides a better and more permanent solution for his patients.
