Improved Shrinkage Behaviour of newly introduced Composite Materials

Objectives: A method for the determination of polymerization shrinkage has been developed and published as German Dental Standard DIN 13907:2007. The purpose of this study was to characterize new resin-based composites (including one ring-opening silorane material FSIL) in comparison to well-known (methacrylate-based) restoratives by means of their volumetric shrinkage values.

Methods: Ten commercially available composites, including three new materials [FSIL, CMP, CME, commercially introduced in 2007], were tested according to the German Standard DIN 13907:2007, n=6). All data were analyzed by OneWay ANOVA/LSD test (p<0.05), means with the same letters are statistically the same.

Results: (Material, Manufacturer, Shrinkage [vol%(SD)]: Filtek Silorane [FSIL] 3M Espe 1,1 (0,1)a; Clearfil Majesty Posterior [CMP] Kuraray 1,6 (0,1)b; Clearfil Majesty Esthetic [CME] Kuraray 1,8 (0,1)b; Grandio [GRA] Voco 2,0 (0,1)c; Tetric Evoceram [TEV] IvoclarVivadent 2,3 (0,1)d; InTens [INT] IvoclarVivadent 2,4 (0,1)d; Filtek Z250 [F250] 3M Espe 2,4 (0,3)d; Clearfil AP-X[CAPX] Kuraray 2,5 (0,3)de; Gradia Direct X [GDX] GC Corp. 2,7 (0,4)def; Filtek Supreme [FSUP] 3M Espe 2,8 (0,2)ef; Tetric Ceram [TEC] IvoclarVivadent 3,0 (0,2)f.

Conclusions: All three new composites [FSIL, CMP, CME] revealed improved volumetric polymerization shrinkage in comparison to the other materials tested. FSIL showed significantly the lowest shrinkage value of all composites tested, possibly due to the silorane monomer contained in the resin matrix. CMP and CME performed significantly improved compared to the formerly introduced composites.
