Resin composite contours [PDF]

open access: yesBritish Dental Journal, 2010
When placing posterior composite resin restorations, clinicians often struggle to achieve good contacts. Frequently contacts that are successful are only confined to the occlusal aspect of the proximal wall. A clinical technique is discussed which achieves the correct contour as well as tight contacts.

Comparison of shear bond strength of etch and rinse, self-etch adhesive system followed by flowable composite resin, and self-adherent composite resin

open access: yesPadjadjaran Journal of Dentistry, 2020
Introduction: The adhesive system strongly influences the bond strength of resin composite to the tooth surface. Aside from the commonly used etch and rinse, and self-etch adhesive system and a new approach called self-adherent composite resin to combine

Improving the surface insulating performance of epoxy resin/Al(2)O(3) composite materials by extending chain of liquid epoxy resin with Me-THPA

open access: yesHigh Voltage, 2019
Basin-type insulators are made by epoxy resin composite materials. Curing defects are easily formed in basin-type insulators, and degrade their insulating performances.

Erosion of Composite Resins [PDF]

open access: yesJournal of Dental Research, 1980
The surface degradation of composite resins caused by accelerated aging was studied. Accelerated aging for 900 hours caused erosion of the resin matrices and exposure of filler particles. Differences in surface profiles after aging suggest that the materials eroded at different rates. Accelerated aging may model erosive wear of composites.
