Abstract
All-ceramic fixed partial dentures have been increasing interest due to demand for esthetic and metal-free restorations of the patients. Yttrium tetragonal zirconia polycrystals has the highest mechanical properties, and promising long term clinical performance. Marginal fit of zirconia fixed partial dentures machined by CAD/CAM systems are lower than metal-ceramic fixed partial dentures but within the range of clinical acceptability. Success rates of frameworks in most studies were 100 % and survival rates were 73.9 - 100 %. The most common complications of zirconia fixed partial dentures were chipping of porcelain veneer. Within the limitations of these studies, conclude that zirconia 3 - 4 unit fixed partial dentures have sufficient stability for replacement of anterior and posterior teeth.
