- Primary Outcome Measures
Name Time Method The primary outcome will be the frequency of technical complications at one year post loading.
- Secondary Outcome Measures
Name Time Method Clinical, biological outcomes (probing depth (PD), bleeding on probing (BOP), plaque index (PI), and radiographic evaluations (marginal bone levels (MBL), together with patient-reported outcome measures (PROMs), OHIP, profilometric measurements, crown to implant ratio, interocclusal<br>relationship, costs, number of interventions to resolve complication will be evaluated at the different time-points.
