Primary Outcome Measures

Name	Time	Method
Bleeding on probing [positive (+) or negative (-)]	About 5-10 years after surgery	When bleeding is present after probing using a periodontal probe with a force of 0.2-0.3 N.
Peri-implant probing depth (mm)	About 5-10 years after surgery	Measured using a periodontal probe inserted into the peri-implant sulcus
Bone loss (mm)	About 5-10 years after surgery	Measured apically from the most coronal portion of the intraosseous part of the implant using periapical radiographs
