Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Mucosa levels were recorded by means of an acrylic stent provided with three direction grooves: mesial, midfacial and distal. All measurements were assessed with a periodontal probe. 1. Papilla levels: a papilla level (mesial papilla level - distal papilla level) is defined as the distance between the top of the corresponding groove and the top of the papilla 2. Midfacial mucosa level: the midfacial level is defined as the distance between the top of the groove and the first contact with the peri-implant mucosa | — |
Secondary
| Measure | Time frame |
|---|---|
| At each re-assessment, namely 3, 6 and 12 months after baseline (i.e. provisional crown connection), mesial and distal marginal bone changes over time were calculated using standardised peri-apical radiographs. | — |
