Composite crown restorations vs. inlays vs. crowns

1. Overview

Dental decay occurs when bacteria in the mouth metabolize acids that attack tooth enamel. As the lesion grows in size are affected other layers of the tooth reaching the pulp.

The first signs of this condition are: pain to thermal and chemical excitants (sweet, cold, warm). Dental caries can be prevented by learning the correct technique of brushing, flossing and other cleaning aids: mouthwash, oral shower, regular controls (usually one to six months), general and local fluoridation (dental decay prophylaxis) and avoid a diet high in carbohydrates, the main source of food for cariogenic bacteria.

After detection of carious lesions, the next step is to treat it. Composite crown restorations are one of the most common and least invasive dental treatment methods.

The composition is a mixture of minerals and resins, with a great mechanical and chemical resistance, used by the dentist to restore tooth function and physiognomy. This material is an excellent cosmetic option, restoring the natural appearance of the tooth.

Composite crown restorations can restore one or more surfaces of the tooth. Composition, no matter how innovative is, microhybrid, with ceramic or polymer component, shows a degree of shrinkage (larger or smaller, depending on the generation to which it belongs), while leading to the appearance of discoloration around fillings.

Fluid seeps at the turn of dental tissue and material and result in a gap between them. This way the coronal restoration is compromised requiring its replacement. To avoid this, there is a new technology – the 3D CAD-CAM (computer-aided design – computer aided grinding) which consists of grinding a ceramic cube by a special device.

Sanding is done following a digital impression that is processed by special software. The ceramic won’t shrink, obtaining a high-strength prosthetic, with a great physiognomy and a stable color.

If the filling is large there are involved more tooth surfaces, yet for some reason it is not indicated the coverage with a crown (tooth is vital), treatment options are an inlay or onlay technique obtained with the CAD-CAM 3D technology.

The inlay is used when coronal destruction is large and the dentist cannot make proper contact points with the adjacent teeth; the onlay is used when it is desired a partial coverage of the vital tooth by this method rebuilt the tooth cusps (those peaks help us in crushing food).

These prosthetic crown restorations, perfectly tailored, are cemented on the tooth by using adhesive techniques in the same session of the visit to the dentist. If the anterior teeth present decay, are chipped, fractured or discolored, a treatment option are dental veneers.

The tooth remains vital, grinding a minimum layer of enamel. Facet, a thin prosthetic composite or ceramic component is cemented to the facial surface of the tooth, restoring the position, shape or color.
