Placing composite resin restorations in esthetically sensitive areas such as the anterior requires understanding of the optical and physical properties of the tooth structure to be replaced and also those of the composites being used. Such knowledge facilitates selection, use, and placement of appropriate materials to replicate the polychromatic effects observed in natural teeth. Dentists should also be thoroughly knowledgeable in natural tooth morphology and how each structural component influences esthetics.
To manage the complexity associated with the direct composite process, using a simplified esthetic composite system such as Amaris, (VOCO America, Inc.) can be beneficial. The Amaris composite system is based on a simplified understanding of tooth structure and color. Dentin shines through enamel and, when combined, these 2 structures determine the color and appearance of a natural tooth.
The Amaris composite technique incorporates only 2 steps: selection and placement of the appropriate opaque dentin composite layer, and selection and placement of a translucent enamel layer that lightens, darkens, or complements the opaque shade. Five opaque shades of O1 to O5 accommodate the full range of dentin shades, and an additional opaque shade, O Bleach, satisfi es the needs for bright restorations. The appropriate matching base shade can be selected using the original material shade guide.
If the selected opaque shade matches the tooth, it is maintained in the final restoration by placing the translucent enamel shade TN (Translucent Neutral). If the base shade appears lighter than the tooth, it can be darkened with the enamel shade TD (Translucent Dark). If the base appears too dark, applying the enamel shade TL (Translucent Light) will lighten its effects.
Because Amaris shades were developed based on a scientifi cally established equal shade distribution of hue, chroma, and value, these 2 composite layers combined— similar to the dentin and enamel structures of natural teeth—produce the desired optical effects in the restoration. Amaris has equal gaps between each opaque shade that are easily closed with 3 translucent modifier shades. By using the recommended 0.5-mm translucent layer, 15 shade combinations and 3 bleach variations are possible for easily and simply creating lifelike restorations that demonstrate natural opalescence and fluorescence. Additionally, the composite demonstrates a high luster finish and perfectly balanced opacity.
Fast, Easy to Polish
The Amaris composite demonstrates low shrinkage, excellent wear resistance, and is radiopaque. It provides clinicians with at least 8 minutes of working time, exhibits a non-sticky, non-slumping and smooth consistency, and is fast and easy to polish.
Also part of the Amaris composite family is Amaris Gingiva, a gingival colored, light-curing chairside composite system that provides practitioners with the option of correcting the esthetic deficiencies associated with gingival recession using a minimally invasive and less costly procedure. This pink-colored composite is specifi cally developed for indications in the cervical area. Amaris Gingiva enables the creation of the perfect gingival shade for each individual case. Dentists therefore can offer patients a more convenient and affordable treatment to correct the appearance of gingival recession.
