| metal base | A metallic portion of a denture base forming a part of the wall of the basal surface of the denture; it serves as a base for the attachment of the plastic (resin) part of the denture and the teeth. (05 Mar 2000) |

| metal ceramic alloys | The fusion of ceramics (porcelain) to an alloy of two or more metals for use in restorative and prosthodontic dentistry. Examples of metal alloys employed include cobalt-chromium, gold-palladium, gold-platinum-palladium, and nickel-based alloys. (12 Dec 1998) |
| metal fume fever | An occupational disease, characterised by malaria-like symptoms, due to inhalation of particles and fumes of metallic oxides. Fumes are formed by evaporation at very high temperature and condensation in air into fine particles. Synonym: brass founder's ague, foundryman's fever, metal fume fever, zinc fume fever.

| metal insert teeth | Prosthetic teeth containing metal cutting surfaces in the occlusal surfaces. (05 Mar 2000) |
| metal interface | In dentistry, a boundary between metal and nonsolvent solder, or between metal and surface oxide. (05 Mar 2000) |
| colloidal metal | A colloidal solution of a metal obtained by passing electric sparks between terminals of the metal in distilled water. Synonym: electrosol. (05 Mar 2000) |
| wood's metal | A fusible alloy consisting of one or two parts of cadmium, two parts of tin, four of lead, with seven or eight part of bismuth. It melts at from 66 deg to 71 deg C. See Fusible metal, under Fusible. Source: Websters Dictionary (01 Mar 1998) |
| heavy metal | A metal with a high specific gravity, typically larger than 5; e.g., Fe, Co, Cu, Mn, Mo, Zn, V. (05 Mar 2000) |
| heavy metal neuropathy | Peripheral nervous system disorders attributed to intoxication of one of the heavy metals: arsenic, gold, lead, mercury, platinum and thallium. (05 Mar 2000) |
| noble metal | A metal that cannot be oxidised by heat alone, nor readily dissolved by acid; e.g., gold, platinum. Synonym: noble element. (05 Mar 2000) |
| d'Arcet's metal | An alloy of lead, bismuth, and tin; used in dentistry. (05 Mar 2000) |
| fusible metal | A metal with a low melting point. (05 Mar 2000) |
| light metal | A metal with a specific gravity of less than 4. (05 Mar 2000) |
| liquid metal | <radiobiology> Metal which has been heated past its melting point and can be used as a working fluid for pumping heat out from a powerplant. Liquid metal used as coolant in a system where significant magnetic fields exist, it behaves differently due to magnetohydrodynamic effects, these cause pressure which resists fluid circulation, suppression of turbulence, and altered flow patterns compared to non-magnetic liquid metal systems.

| liquid-metal fast-breeder reactor | <physics> Fission breeder reactor concept using liquid-metal coolant and breeding additional fuel off fast neutrons. See: breeder reactor. (09 Oct 1997) |
