Porcelain Inlays and Onlays




Porcelain Inlays and Onlays

Fillings may be the most common way of repairing cavities, but they’re not the only game in town.

If you have a mild to moderate amount of decay or damage on the biting surface of your back teeth—or are looking to replace your old metal fillings—porcelain inlays or onlays are an attractive and durable alternative.

Inlays are used to fill in areas within the cusps or top projections of a tooth, while onlays extend over one or more of them. Crafted from solid porcelain, they are not only virtually undetectable to the naked eye but also last far longer than traditional fillings.

In most offices, the procedure for inlays and onlays is the same as it is for crowns: one appointment to prepare the tooth, take a bite impression, and fit the patient with a “temporary”, and another to put in the permanent fixture.

Not so at Metropolitan Dental. Ours is one of the few offices in Ottawa equipped to mill porcelain on the premises using CEREC 3D technology. This computer-assisted system enables us to design, manufacture, and place an inlay or onlay that is precisely matched to your tooth—all in a matter of minutes.
The precise fit and solid bond of a porcelain inlay or onlay strengthens your tooth by up to 75 percent, helps prevent bacteria from entering and causing future decay, and requires less of the tooth’s structure to be removed than a regular filling. And, unlike metal, porcelain doesn’t expand or contract in response to temperature changes—so it won’t weaken or fracture your teeth over time.
