Zirconia implants have lower survival rates and higher rate of mucositis than conventional titanium implants

• The esthetic outcome was moderate to almost perfect, with a high level of patient satisfaction.

• No significant association was found between survival rate and the presence of mucositis around one- or two-piece implants or any other study variable.

The survival rate is low for one- and two-piece zirconia implants. Both types of implants demonstrated a low mechanical complication rate. The incidence of periimplantitis is low but mucositis is present in 50%. Patient satisfaction related to esthetics and function is moderate to high. They represent a good option for patients requiring an alternative to titanium implants. Zirconia implants appear to be an alternative to the titanium option and may be indicated for patients requiring “metal-free” restorations.
