EVALUATIONS THE EFFECTS OF DIFFERENT SURFACE TREATMENTS ON MICROLEAKAGE OF HEAT CURE ACRYLIC RESIN AT CO-CR ALLOY AND PEEK POLYMER INTERFACE
Journal Title: World Journal of Pharmaceutical Research - Year 2019, Vol 8, Issue 2
Abstract
Background: Microleakage at framework components and acrylic resin junction in removable partial denture may result from poor chemical bonding, PEEK one of the alternative framework materials used to overcome like this drawback. Objectives: Evaluate the microleakage of acrylic resin to Co-Cr alloy and PEEK using different surface treatments. Materials and Methods: Sixty specimens prepared in regtinguler shap with contained grid and divided according to framework material type into two groups Co-Cr alloy and PEEK (n=30/ group), then each main groups subdivided according to surface teratment type to three subgroups (n=10/ group) control group (no surface treatment), air abrasive group (110 μm alumina oxid) and acid etch group (98% sulfuric acid). The specimens were thermocycled (3000 cycles) after clear heat cured acrylic resin application, then immersed in sodium fluorescein dye solution (0.1 g/1000mL) for 24 hours at room temperature, microleakage assessment done by counting the grids that exhibited dye penetration under ultraviolet-light. Data were analyzed LSD test at (p<0.05). Characterizations performed through scanning electron microscope and X-Ray diffraction. Results: PEEK acid etch and air abrasive surface treatment groups show the lowest microleakage values, while Co-Cr alloy acid etch and control groups had the highest microleakage values. The results revealed highly significant differences between all groups at P<0.01. Conclusion: Microleakage reduced with air abrasive treatment for both Co-Cr and PEEK; however, sulfuric acid treatment efficiently improves the microleakage reduction with PEEK whereas exhibited the highest microleakage extension with Co-Cr.
