Surface finish of dental composite restorative materials

Surface finish of dental composite restorative materials.

Five composite filling materials were finished using six finishing procedures currently in clinical use. The average roughness produced by each procedure was measured by means of a Surfanalyzer with four replications for each procedure on each of the five materials. Statistical analysis indicated that finishing with silicon carbide disks produced the smoothest surfaces. Acceptable surfaces were...

Surface Finish Produced on 5 Aesthetic Restorative Materials by New Polishing Systems

Objective: The purpose of this study was to investigate the surface finish of 5 different aesthetic restorative materials after polishing with 3 different polishing systems. Materials and Method: The materials included 2 nano-filled composites (Tetric Evo Ceram and Grandio), a compomer (Compoglass F), a resin-modified glass ionomer cement (Fuji II LC), and a highly viscous glass-ionomer cement ...

Two-body wear of dental restorative materials.

AIM The aim of this in vitro study was to determine the two-body wear resistance of modern direct dental restorative materials. METHODS Eight standardized specimens were prepared from 14 dental restorative materials (nano-, micro-, hybrid-, macrofilled composites; compomer, silorane, ormocer); a veneering composite (Sinfony) and enamel were used for reference. Vickers hardness (HV) and inorga...

Friction and wear of restorative dental materials.

Many different instruments have been developed for the measurement of friction and wear.1-5 Often the instrument was designed to accommodate some particular type of material, environment, or test condition. Studies reported in the dental literature have been limited to wear measurements with simulated toothbrushing methods,6-9 or on prosthetic teeth mounted on an articulator.10 This study will ...
