*2.5. Parameters Related to Dental Implant*

A calibrated investigator (T.A.) gathered the data from patient's records relating to the implant dimensions (diameter x length), jaw location (mandible or maxilla), surface characteristics (smooth or moderately rough surfaces), insertion torque (in Newton centimeters [Ncm]), implant–abutment connection (platform-switching), prosthetic restoration type (screw- or cement-retained). "Implant success" was described on the basis of the following characteristics: (1) existence of a fully functional implant within the oral cavity; (2) selfevaluated satisfaction of the patient regarding implant and the associated prosthesis [28].
