| Abstract: Maxillary sinus pneumatization and resorption of the posterior alveolar bone complicate implant placement in the posterior maxillary area, where the implant placement procedure is very challenging. Aim: To assess the efficacy of the PEEK material that can maintain the Schneiderian membrane elevated and close the sinus window during the healing period, and to assess the quality and quantity of bone formation in maxillary sinus augmentation. Patients and methods: twenty-four patients with clinical and radiological diagnoses of maxillary sinus pneumatization with remaining bone height less than 5mm needing implants after lateral approach sinus augmentation surgery with age range 20-50 years. The patients in the study were divided into two equal groups. In twelve patients (tested group), the maxillary sinus was lifted using PEEK and PRF product after blood centrifuging. Twelve patients in the control group's maxillary sinus were lifted using the PEEK device alone. Results: Six months after Schneiderian membrane elevation using the PEEK device alone (control group) or with PRF (tested group) revealed an insignificant difference in the quantity (mm) using CBCT (P>0.05), while the significant difference in quality (Percentage of bone formation %) using histomorphometric analysis of the newly formed bone between both groups (P value<0.0001).Conclusion: Custom-made PEEK novel design is a predictable method in sinus lift procedures with predictable results, irrespective of the presence or absence of PRF as it proved to be of little value as a sole augmentation material. | ||||
