Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The use of translucent monolithic zirconia for implant-supported crowns (without veneering ceramic) may reduce the technical complication rate and allow for sufficient aesthetic results in the molar region. To date, no clinical trial investigating monolithic zirconia crowns for single molar implants is available.
The primary outcome of the study is the technical complication rate. This outcome represents an indicator for the prosthetic success of the implant-supported crown. The main biological secondary outcomes are marginal bone level, histological signs of inflammation, and presence of pathogenic bacteria. Further outcomes are crown survival, wear of the crown and of the antagonist.
