A Study on Repair Restoration with High Filler Containing Indirect Composites-Surface Treatment for Light Cured Type Resins-

Microstructural Properties and Surface Properties of a New Resin Composite Employing Structural Color Technology

“…The notable structural properties of OC that were clarified by the alkaline degradation testing include that there was wide dispersion of spherical organic fillers with a distribution of various particle sizes, spherical inorganic fillers of 260 nm in diameter were evenly distributed at almost the same density both within the organic filler and within the base resin surround it, but the organic filler and base resin, which are thought to be difficult to couple [12][13][14][15][16] , were strongly bound without any gaps forming in an alkaline environment; although the surface layer of the organic filler experienced alkaline degradation, the center part had little alkaline degradation, similar to the matrix surrounding the organic fillers. Kishimoto 5) observed the state of alkaline degradation of various conventional resin composites containing pigments, and noted that, in all of the resins, the interface between the organic filler and the base resin in particular became less tight and gaps form more readily in an alkaline condition.…”
