Table 2 Loading criteria applied at implant placement surgery (loading criteria 1 (LC1)) and attachment of provisional restoration (loading criteria 2 (LC2))

From: A randomized, 12-month controlled trial to evaluate non-inferiority of early compared to conventional loading of modSLA implants in single tooth gaps

Loading criteria 1 Loading criteria 2
• Sufficient oral hygiene • At least 1 mm bone volume around the implanta • No major dehiscence (<3 mm) or other bone defects at the implant site • Bone quality I–III • Adequate insertion torque (≥15 Ncm during placement of the healing cap) • Suitable implant position • Dental radiograph shows three threads of implant fixture • Sufficient oral hygiene • No rotational movement of the implantb during abutment connection at 15 Ncm • No moderate or severe pain at the implant site during abutment connection at 15 Ncm • Suitable implant position • Dental radiograph shows three threads of implant fixture
  1. Any patients not fulfilling LC1 received an alternative treatment, e.g., bridge, false teeth, and were subsequently included in the safety analysis set (SAS)
  2. aThat is, for a 4.1-mm diameter 10-mm-long implant, crestal width and bone height should be 6.1 and 11 mm, respectively
  3. bDuring abutment connection
