Polymerization stress and cuspal deflection of low-shrinkage commercial composites

The effect of composite placement technique on the internal adaptation, gap formation and microshear bond strength

“…On the other hand, the performance of RBCs is influenced by several factors, including the design and size of the restoration, placement technique and material itself (1). Although most RBCs meet basic expectations of dentists in terms of adhesion, sealing, wear resistance, fracture toughness and biocompatibility, the main deficiencies of RBCs, such as polymerization shrinkage and internal stress, still exist (2,3).…”

“…Total restoration volume (mean -mm 3 ), mean void dimensions (µm3 ) observed in occlusal, cervical, pulpal, in the bulk of the material and the percentage of voids (% 10 -8 ) acquired from µCT data. Significant differences between group were given on table using different superscript letters.…”
