Restorations (Inlays & Onlays)
Nowadays there are many options for dental restorations that can be considered when repairing worn, decayed, damaged or missing teeth to help you gain your beautiful smile. There are two main types of dental restorations, direct or indirect. A direct restoration involves an immediate filling into a prepared tooth cavity. An indirect restoration involves customizing the tooth being replaced with either a crown, inlay or onlay.
An inlay restoration consists of a solid substance, such as metal or porcelain, it’s then fitted and cemented into place within a cavity. An onlay restoration is essentially the same as an inlay except, it extends to replace a cusp (a cusp is the pointed or rounded projection on the chewing surface of a tooth) and covers the surface of a tooth completely.
For situations in which a composite restoration would be insufficient and could potentially compromise the structural integrity of a tooth, inlays and onlays are often used to restore the tooth. Though they can be made from gold, silver, composite or ceramic resin, porcelain has become the material of choice because of its strength, durability and ability to match a tooth's natural hue.
