Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Patient reported outcome measure (PROM): satisfaction with impression technique via VAS questionnaire	After impression-taking, questionnaires were handed out to the participants to evaluate PROMs via visual analog scales (VAS). Six categories were assessed: (1) overall treatment time of impression-taking procedure (0=unsatisfactory to 10=excellent); (2) convenience level of the impression technique (0=unsatisfactory to 10=excellent); (3) anxiety level of impression technique (0=low to 10=high); (4) bad taste and (5) nausea caused by the impression (each 0=no sensation to 10=a lot of sensation); and (6) pain during impression-taking procedure (0=no pain to 10=a lot of pain).	After impression, At first visit within 30 minutes
Primary	Patient reported outcome measure (PROM): satisfaction with final implant restoration via VAS questionnaire	Patients were requested to score their feeling on screw-retained monolithic implant crowns in a 10cm VAS one week after delivery of the final implant crowns. The level of patients' satisfaction was measured in four categories: (1) perception of the overall treatment outcome (0=unsatisfactory to 10=excellent); (2) opinion on the function of the restoration (0=unsatisfactory to 10=excellent); (3) esthetic perspective (0=unsatisfactory to 10=excellent), and (4) ease of oral hygiene care (0=unsatisfactory to 10=excellent).	1 week after prosthesis delivery
Secondary	Functional implant prosthodontic score (FIPS)	objective evaluation by a dental professional applying the functional implant prosthodontic score (FIPS).	Prosthesis delivery visit, an average of 2 weeks after first visit for impression procedure
