ABSTRACT

The aim of this paper is to present the different components of the composites currently usedin dentistry and provide the professional who can provide the basis of criteria to be taken into account to select one or the other depending on the therapeutic requirements. Most composites used in dentistry are hybrid materials, are so named because they are composed of polymer groups reinforced by an inorganic phase glass of different composition, size and percentage of filler. The fluids orcondensable composites have tried to answer some functional requirements, but with limited success in improving their properties. For sources of polymerization, both halogen lamps, conventional or high power density, such as LEDs, which provide a gradual increase in light intensity, are very useful for reducing shrinkage of the material. When selecting a composite clinic is assessed whetherpredominates the mechanical or aesthetic requirements: in the first case select the material having larger volume of filler, while the second will be the minimum particle size of the factor important. The existence of additional elements such as opaques and stains, improves the aesthetic results with these materials. Equally, the spread of other therapeutic procedures, such as tooth bleaching, has led tothe need to design composites with shades to suit special color situations found in teeth treated with these procedures.

Keywords: Composite resins, inorganic fillers, organic matrix, polymerization, clinical applications.

ABSTRACT

The aim of this work is to present the different components of thecomposites currently used in dentistry and furnish dentists with a basis That Can Provide criteria for choosing one or another to suit Their therapeutic requirements. Most composites used in dentistry are hybrid materials, so-called Because They are composed of polymer groups reinforced by an inorganic phase of glass fillers with different compositions, particle sizes and fill percentages. Flowable orcondensable composites have Attempted to Provide an answer to Certain Functional Requirements, although They have not been too successful at Improving properties. Turning to Polymerisation initiators, Both halogen lamps, high intensity Whether or conventional, and LED curing lights Which Provide a gradual Increase in light intensity are very useful for Reducing shrinkage of the composite material.The choice of a composite clinical Must Consider Whether Priority Should be Given to mechanical or aesthetic requirements: mechanical considerations are paramount if the item With The greatest volume of filler will be CHOSEN, if aesthetic considerations predominate, particle size will be the MOST important factor. Additional components opaques and tints Such as make it possible to Improve The...
