Abstract: Preservation of bone volume after tooth loss is necessary for successful implant placement. The aim of the present study is to compare changes in bone height and pathological problems using autogenous bone with collagen material as well as surgicel alone. This is a clinical trial study in which 39 patients requiring implants in the posterior maxilla were selected. Patients were randomly divided into control and treatment groups. In the control group, autogenous tuberosity bone was used to increase alveolar height after sinus shift. In the case of sinus membrane rupture, a resorbable collagen membrane along with autogenous bone was used. In treatment group, surgicel was used alone to shift sinus membrane. T-test was used for statistical comparison. In control group, pathological abnormalities in the nasal passages were more than the treatment group. Statistical analysis revealed a significant difference between the mean bone height after surgery in the control (10.4±2.6) and treatment groups (12.5±2.7) (p=0.02). According to the results of present study, the use of surgicel has a greater effect on bone growth compared with autogenous bone and collagen membrane.
