The effect of different bonding systems on shear bond strength of repaired composite resin

Evaluation of Different Surface Treatment Effects and Micromorphology on the Repair Bond Strength of the Aged Nanohybrid and Microhybrid Composites

“…The majority of the evaluated methods in this study generated repair bond strengths that were greater than the advised bond strengths relevant to various clinical scenarios. Studies demonstrated positive results related to new siloxane linkages between resin and fillers when primers were used [7,20]. Overall, there was a significant difference between the bond strengths of the two materials, Filtek Supreme XT and Filtek Supreme Z250, for the repair of aged composite, and using a new composite material to restore a damaged composite restoration was not weak bonding [21].…”

Smart Biomaterials: An Evolving Paradigm in Dentistry

“…This causes the structure of the material to gradually deteriorate and eventually fail [17]. Composites fixed using a self-repairing process formulated on microcapsules might be effective to a greater extent than those restored using macroscopic repair techniques, some of which have been found to not produce sufficient mechanical properties of the repaired composite with an appealing outcome [18]. A self-healing composite contains a healing powder and a healing liquid which is encapsulated by silica nanoparticles.…”
