McKinney, Texas

Dr. Chang attended Baltimore College of Dentistry in Maryland where he earned his Doctorate of Dental Surgery in 2003.

While in San Antonio, he also completed his research on bio-modification of titanium surfaces to improve initial implant stability and earned his Master’s degree in the school of Biological Science.

He was the first dentist in the U.S. to have successfully restored full arch implant cases utilizing all zirconia, screw retained three unit FPDs, as well as the Procera all zirconia, full arch screw retained hybrid restoration (fixed denture).
Less than a year after completing his residency program, he successfully challenged both the American Board of Periodontology & American Board of Prosthodontics’ board examinations. He is one of five dual board-certified dental specialists in both periodontics and prosthodontics in the United States.
