This randomized controlled trial (RCT) analyzed monolithic single-unit implant restorations out of lithium disilicate (LS2) or polymer-infiltrated ceramic networks (PICN) in a chairside digital workflow (Test) and a conventional protocol (Control). The primary outcome was subjective patient perception in terms of PROMs comparing digital and conventional impression techniques as well as patients' satisfaction related to the final implant restoration among difference workflows and materials. The secondary outcome was to investigate the objective evaluation by a dental professional applying the functional implant prosthodontic score (FIPS). The null-hypothesis of this RCT was that both workflows and the two materials for the monolithic implant restorations had comparable results with respect to the defined outcomes.
