Dr. Azadeh Khajavi specializes in full mouth reconstruction using metal-free dental implants, particularly zirconia implants. Zirconia implants have been used since 1987 as an alternative to titanium implants. Some benefits of zirconia implants are that they are designed to withstand force and pressure over time, have a one-piece design that resists potential infections, and can be placed immediately after tooth extraction requiring less invasive surgery.
