内容記述 | Low-temperature atmospheric pressure plasma (LT-APP) treatment can be used for surface energy activation and contaminant removal from minute gaps between fiber posts without increased risk of deformation due to physical force or heat. It is an effective method of surface treatment in clinical dentistry. We investigated its efficacy for fiber posts. In Experiment 1, we evaluated the impact of LT-APP on the bending strength of the fiber posts. A three-point bending test was conducted using a universal testing machine. In Experiment 2, we investigated the effect of LT-APP treatment on the adhesion strength between the fiber post and both the abutment construction resin and the adhesive resin cement. A push-out test was conducted using a universal testing machine. Experiment 1 showed that the LT-APP treatment did not weaken the physical properties of the fiber post. Experiment 2 showed that when the LT-APP treatment was performed before the silane treatment, the bond strength improved between the fiber post, and both the composite resin core and the adhesive resin cement. The results indicated that LT-APP treatment of fiber posts is effective. |
