Types of Dental Implant Materials — Titanium vs Zirconia

Mar 12, 2015 · Both types of implants require several months for the bone to fuse or grow against the implant before we can place the final teeth. With one-piece zirconia implants, this healing phase can be a little more tricky as we cannot bury the implant under the gum tissue. if there is pressure or movement of the implant, it will not osseointegrate.
