Objectives: The main goal of this study was to evaluate the relationship between postoperative pain and short-term implant survival. Objective parameters, such as implant-related factors (type, diameter, length) and the surgical approach were also assessed to correlate them with pain. Materials and Methods: This prospective, single-center study consisted of 144 patients scheduled for the surgical placement of one or more implants either with conventional surgery or with sinus-lifting together. All patients were asked to complete a questionnaire form of pain with a visual-analog scale (VAS, 1–10) for 7 days following surgery. The association of pain scores at each time-point was assessed on implant- and surgery-related factors. Results: The overall cumulative survival rate of 546 implants in 144 patients was 98.17 % (10 implants lost) after 1-year follow-up. No statistical difference was found in pain (VAS) scores between patients with loss and survived implants at any observation period. The length and diameter of placed implants and the presence of a sinus-lifting procedure did not influence the pain scores at any period (P > 0.05). In patients with bilateral sinus lifting, the decrease in pain scores was significant after 3 days (P < 0.05), whereas it was significant after 6 hours for the conventionally treated group (P < 0.01). Although no severe pain was reported at any time, this study found a significant difference in pain intensities among different implant brands. Conclusions: This study was able to show that increased postoperative pain is not a sign of early implant failure. In addition to this, the implant dimensions and presence of sinus lifting procedure did not influence the pain experience. However, the bilateral sinus lifting prolongs the recovery time.
