Dental restorations can be divided into direct restorations and indirect restorations. Direct restorations are those “fillings” that are incrementally placed into a prepared cavity so that the tooth is restored to full function and contour. Indirect restorations would include those restorations which are fabricated outside of the mouth, usually from a standard impression or a digital impression, then cemented or bonded as a single unit. These restorations would include inlays, onlays, crowns and bridges.
