Bond strengths of chemically dissimilar repaired composite resins

Expanded use of composite resins has necessitated repair of fractured, discolored, and former restorations. Laboratory investigations have demonstrated that new composite resin can be bonded to cured composite resin of the same chemistry. The surface chemistry of three composite resins of dissimilar...

Zusammenfassung:	Expanded use of composite resins has necessitated repair of fractured, discolored, and former restorations. Laboratory investigations have demonstrated that new composite resin can be bonded to cured composite resin of the same chemistry. The surface chemistry of three composite resins of dissimilar matrix formulae were examined by infrared spectroscopy and the tensile bond strengths of heterogeneous repairs and the site of repair failures were determined.
