Inlays and Onlays
Kellyville Dentist
Badly damaged or malformed teeth can be replaced by implants, or restored with complete crowns. These procedures are two of the great advancements of modern dentistry. But sometimes a damaged tooth does not need such complete replacement. A partially damaged tooth can be satisfactorily restored with a partial replacement. In these cases we uses, overlays, inlays and onlays. For front teeth we might use veneers.
Inlays – Glenhaven Dental
Inlays are used to replace the top centre part of a molar tooth. This is the part of the tooth that is used for chewing. It is prone to damage both because of the chewing action and because food debris that gets stuck in the tooth’s indentations can lead to decay.
Inlays only replace the grooved section at the top of the molar. The rest of the tooth can be retained.
Onlays – Castle Hill Dental
Onlays are like inlays but they replace more of the tooth’s upper surface.
Onlays and Inlays must be custom made to fit the individual’s tooth. This is achieved by making a model of the original tooth and using computer aided design and manufacturing (CAD and CAM) at a dental lab.
Overlays – Dentist Baulkham Hills
An overlay is more than an inlay or onlay and less than a complete crown. It replaces the whole top of the molar tooth while keeping the base and inner part of the molar.
Like inlays and onlays this requires making a model of the tooth and producing a computer manufactured replacement part.
Bella vista Dentist
Inlays and onlays will often now be used where we once used fillings. Instead of filling the tooth we replace the damaged section with the inlay/onlay. This replacement material is much harder than the filling, and therefore longer lasting. It also looks far more natural. It is the same lithium disilicate or zirconia material that is used for crowns.
