Design outcomes

Primary

Measure	Time frame
The primary outcome of the study is the technical complication rate after 3 years of clinical service, assessed by means of standardized USPHS criteria.	—

Secondary

Measure	Time frame
Secondary endpoints will be assessed at each follow-up visit (1- /3- and 5-years). • Secondary caries (assessed on a radiograph and by clinical examination) • The biological outcome (assessed with a periodontal probe: bleeding on probing, pocket depth, plaque score) • The FDP (fixed dental prosthesis) survival (assessed by means of standardized USPHS criteria) • The wear rate of the FDP and the antagonists (assessed by means of a silicone impression)	—
