Comparative Evaluation of Shear Bond Strength of Prefabricated Composite Veneer Bonded to PolyEther-Ether Ketone Framework using two Different Bonding Systems: an Invitro Study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2018, Vol 17, Issue 4
Abstract
Objectives: The aim of this study was to evaluate and compare the shear bond strength of prefabricated composite veneer bonded to polyether-etherketone(PEEK) implant prosthetic framework using two different bonding systems. Materials and methods: 40 pre-fabricated composite veneers (novo.lign A -bredent GmbH,Germany) for central incisors were selected and cemented to a PEEKframework using two different bonding systems–Group A using visio.link primer-combo.lign luting composite resin (bredent GmbH,Germany) and Group B using GC Composite Primer(GC,Europe) and LuxaCore Z bonding resin(DMG, Germany).After ageing the specimens by storage in distilled water at room temperature for 24 hours, shear bond strength of composite veneer bonding was tested on universal testing machiene. Results: Shear bond strength valueswere more for Group A (5.95MPa) than Group B (3.19MPa) which was statistically significant. SEM analysis showed that mixed type of bond failure were more commonly observed in thebonding systems. Conclusion: Shear bond strength of visio.link-combo.lign bonding system was more than GC composite primer-LuxaCore Z bonding system. The type of bond failure was mostly mixed failure in both the groups along with cohesive failure within the veneer suggesting that the veneering system was not appropriate for the PEEK frameworks
