Summary
60 bridge frameworks are CAD/CAM manufactured from zirconia-ceramic; 30 bridges are veneered with CAD/CAM fabricated lithium disilicate ceramic, 30 bridges are manually layered. The goal is to compare clinical survival , biological or technical behaviour of the restorations.
Detailed description
Randomized prospective controlled clinical study with three-unit posterior bridges made of zirconia-ceramic to compare veneering with manually layering or CAD/CAM fabricated lithium disilicate ceramic veneers. The hypothesis is that there is no difference in clinical survival of the restorations and no difference in biological or technical behaviour.
