Abstract

Background: Various techniques for maxillary sinus augmentation have been utilized using different materials to improve the autogenous bone formation in maxillary sinus, enhancing proper positioning of dental implants.
Objective: The aim of this study is to evaluate the sinus lift procedure using PTFE titanium reinforced membrane to maintain the space formed after schneiderian membrane elevation followed by simultaneous implant placement.
Patients and Methods: this case series was carried out on 12 patients with average age 52.3 years old with posterior maxillary bone 4-6 mm. Implants were placed immediately after sinus lift procedure and the sinus membrane was maintained in position using PTFE titanium reinforced membrane. Patients were followed up for 6 months clinically and radiographically.
Results: All patients except one patient experienced pain and swelling few days after surgery which decreased gradually until completely disappeared one week postoperatively, this single case suffered from infection 3 months after surgery led to implant failure. All patients except the failed case showed a significant increase in bone height, bone density and implant stability.
Conclusion: Results in this study have proven the effectiveness of the titanium reinforced PTFE as a space maintainer facilitating new bone formation.
