| Popis: | Purpose The purpose of this study was to achieve more retention and stability and to delay or prevent screw loosening. Materials and methods Twenty implants (Implantium 3.4 mm, Dentium, Seoul, Korea) were divided into 2 groups (n = 20). In the first group, an adhesive material was applied around the screw of the abutments (test group). In the second group, the screws are soaked in saliva (control group). All the screws were torqued under 30 N/cm, Then, the samples were gone through a cyclic fatigue loading process. After cyclic loading, we detorqued screws and calculated detorque value. Results In comparison with the control group, all the implant screws in the test group were smeared with the adhesive material, showing significant higher detorque value. Conclusion There are significantly higher detorque values in the group with adhesive. It is recommended to make biocompatible adhesive to reduce screw loosening. |
