Introduction: Implant placement in the posterior atrophic maxilla sometimes represents a challenge and requires pre-implant sinus floor elevation surgery. The objective of this study was to evaluate the success rate of sinus floor elevation techniques performed using the lateral and crestal approaches.
Materials and Methods: A retrospective study was conducted on 59 cases. Two surgical techniques were used: 32 patients underwent the crestal approach, whereas 27 patients were treated using the lateral approach.
Results: The success rate of the crestal sinus lift technique was 93.84%, with a failure or complication rate of 6.16%. The complications included two cases of sinus membrane perforation, one case of vestibular cortical plate fracture, and one case of implant instability.
For the second technique, the success rate was 90.56%, with six failure cases, represented by three cases of membrane perforation, two cases of sinusitis, and one case of hemorrhage due to injury of the alveolo-antral artery.
Conclusion: Mastery of the sinus lift technique enables initiation of implant treatment and helps meet patients’ expectations.
