Abstract

Purpose:This research aimed to assess the amount of bone formation with PEEK (test group) in compared to Titanium Meshwork (control group) in maxillary sinus lifting using CBCT and assessment
of the biocompatibility of the Meshwork and PEEK with the schneiderian membrane integrity.
Materials and Methods: Patients were divided into two groups ; the test group had their maxillary sinuses
lifted using PEEK, while the control group had their sinuses lifted using titanium mesh.Clinical examination
includes assessment of biocompatibility of Schneiderian membrane ; Postoperative healing and radiographic examination using CBCT at 6 months to assess newly produced bone in both groups.
Results : Although there was no significant difference in newly produced bone between both groups, the test group had stronger Schneiderian membrane biocompatibility than the control group.
Conclusion: PEEK and titanium mesh are used as space-maintenance devices; however; in terms of application, the PEEK device demonstrated greater biocompatibility with the Schneiderian membrane.
