Fracture of Zirconia Abutments in Implant Treatments: A Systematic Review

Conclusions: Lower fracture rates were reported for internal connection with metal component (2-piece) zirconia abutments compared with external and internal full-zirconia connection (one-piece) zirconia abutments. Overpreparation and overload should be avoided in case of zirconia abutments.
