Abstract

Objectives: The objective of this study was to evaluate clinically and radiographically use of oxidized regenerated cellulose as a graft material in transalveolar sinus lifting and implant insertion.
Subjects and methods: Eighteen implants were inserted in sixteen patients with missed upper molar teeth. They were divided into two groups as the following: group A (study group)included patients who received dental implants after sinus lift with oxidized regenerated cellulose graft, group B(control group) included patients who received implants after sinus lift without graft. The patients were clinically and radiographically evaluated preoperatively and postoperatively immediate and 6 months postsurgery. Clinical evaluation included pain and discomfort, swelling and implant stability using osstell. Radiographical evaluation was done by CBCT to measure the bone height and density.
Results: Both sinus lifted groups with or without graft have significant success rates with superior radiographic results of oxidized cellulose grafted group over non grafted one after a follow up period up to 6 months.
Conclusion: Transealveolar sinus lifting with Oxidized regenerated cellulose graft is a promising graft for sinus augmentation.

Key words: Oxidized regenerated cellulose, Transalveolar sinus floor elevation, CBCT, Dental implants.
