Table 2 Outcome success criteria

From: Comparative evaluation of the stability of two different dental implant designs and surgical protocols—a pilot study

Implant success Clinically immobile when tested manually and/or with RFA (minimum ISQ = 65)
Absence of peri-implant radiolucency present on an undistorted radiograph
Absence of unresolved pain, discomfort, infection or neuropathy, or peri-implant soft tissue complications attributable to the implant
Implant placement that does not preclude delivery of a prosthetic crown with an appearance that is satisfactory to the patient and the dentist
Crestal bone loss that is <1.5 mm after the first year of loading followed by not more than 0.2 mm of annual crestal bone loss thereafter
Prosthesis success Absence of unresolved peri-implant soft-tissue complications, such as bleeding, swelling, suppuration or recession, attributable to the prosthetic restoration
Absence of unresolved prosthetic complications, such as screw loosening or porcelain fracture
Absence of esthetic complications, such as implant or abutment visibility, or compromised porcelain translucency or mismatched prosthetic tooth color
Early loading success: a functional provisional crown placed ≥3 weeks and <3–6 months after implant placement, followed by delivery of a definitive crown after 12 months of function
