Angel Dust is also known as PCP. It is known as a Hallucinogen, but has the effects of a stimulant, an anesthetic, or a narcotic pain-killer, depending on the amount taken.
They are generally made of porcelain or gold. A dental inlay is a prosthesis made of a solid substance and cemented into a cavity inside a tooth. A dental onlay is similar to an inlay, except that onlays lay on or over a cusp, which is a portion of the toothâs surface.
Introduction. 1  Historically, gold was the material of choice for inlays and onlays. The accuracy and malleability of gold made it an ideal material to restore lost tooth structure and protect weakened cusps destroyed by caries and trauma. 2  The most common indication for inlays or onlays is extensively restored and weakened teeth. The distinction between the two designs is unclear but simply those restorations without cuspal coverage that remain within the body of the tooth would be considered inlays (Figure 12.1) whereas onlays replace tooth tissue including cusps (Figure 12.2).
