Patient Perception and Oral Function of Implant Restorations

The investigators will compare splinted versus non-splinted crowns in a randomized design. Whether the crowns will be splinted or not are decided by distant randomization separate from clinicians conducting the trial. Twenty sealed envelopes will be opened where its stands whether the crowns has to be splinted crowns or non-splinted crowns. The implants in the splinted side will have an intermediate titanium abutment and impression will be taken at abutment level, whereas impressions in the non-splinted side will be taken directly at the fixture level. The splinted as well as the non-splinted crowns will be screw-retained and produced in monolithic zirconia. An open-tray technique / (scanning) will be used for both reconstructions.
