Patient Perception and Oral Function of Implant Restorations
Sponsor: University of Copenhagen
Summary
The overall aim is to evaluate the patient-reported outcome and efficiency of replacing posterior teeth with implant-supported crowns compared to RDPs and no treatment. Sub-aims are to evaluate a new 3D-methods for registration of occlusion and to test two crown designs. Thus, the study design has three aims: * To analyze patient perception including OHRQoL, when missing posterior teeth are replaced with implant-supported crowns compared to removable dental prostheses (RDPs) or no replacement. * To develop and validate new 3D digital methods for assessing occlusal contacts between upper and lower jaw and to analyze the methods relation to masticatory ability and efficiency. * To compare the difference in biological technical outcomes between splinted and non-splinted implant-supported crowns over time.

Splinted
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.
