Subjects and Methods: The current study include 10 maxillary sinuses, The study patients were partially or completely edentulous in the posterior maxilla and required unilateral or bilateral maxillary sinus augmentation. All patients were selected from the out-patient clinic of Oral and Maxillofacial Surgery Department, faculty of oral and dental medicine, Cairo University. Results: The sinuses were divided into two equal groups (study and control groups), both groups underwent maxillary sinus lift procedures using either space-maintaining titanium screws for the study group or space-maintaining titanium mesh for the control group. The study was a double blind one (participants and outcome assessors were blinded throughout the study). Conclusion: application of titanium mish with micro screws to support the sinus membrane was easier clinically than using long titanium screws alone, as the accessibility and direction of drilling was more difficult when long titanium screws were used  }, keywords = {maxillary sinus floor,titanium mesh,titanium screws}, url = {https://adjc.journals.ekb.eg/article_118966.html}, eprint = {https://adjc.journals.ekb.eg/article_118966_5ec548f33fb192cd846211bc3370b305.pdf} }
