| composite dental cement | An organic dental cement modified by the inclusion of inorganic materials treated with a coupling agent to bond them to the polymers. (05 Mar 2000) |
| composite graft | A graft composed of several structures, such as skin and cartilage or a full-thickness segment of the ear. (05 Mar 2000) |
| composite joint | A joint composed of three or more skeletal elements, or in which two anatomically separate joints function as a unit. For example, the telonavicular and calcaneocuboid joints act together as the compound transverse tarsal joint. Synonym: articulatio complexa, articulatio composita, composite joint, compound articulation. (05 Mar 2000) |
| composite resin | A synthetic resin usually acrylic based, to which a glass or natural silica filter has been added. Used mainly in dental restorative procedures. Origin: L. Compositus, put together, fr. Compono, to put together (05 Mar 2000) |
| composite resins | Synthetic resins, usually acrylic based, to which a high percentage (usually about 75% to 80%) of an inert filler has been added. Glass beads or rods, borosilicate glass powder, and natural silica are the most commonly used fillers. Filler particles are coated with a coupling agent that binds the particles to the resin matrix. They are used chiefly in dental restorative procedures. (12 Dec 1998) |
| composite transposon | <molecular biology> A segment of DNA which contains the insertion elements at either end but can contain just about anything in the middle (genes, markers, etc.). These types of transposons tend to be very large, and many of them came about when the inner two insertion elements of two smaller transposons stopped working and only the two at the far ends continue to work, so that when the transposon moves, it takes everything in between the two original transposons with it. Some composite transposons are used in genetics experiments, Tn5 and Tn10 are two such composite transposons which have genes that encode resistance to certain antibiotics. (05 Jan 1998) |
| void metal composite | A porous metal structure that enables tissue growth within the openings to establish long-term attachment between prosthesis and tissue. (05 Mar 2000) |

| direct composite resin restoration | A direct restoration made by inserting a plastic mix of auto or light-polymerised resins in a cavity prepared in a tooth. Synonym: direct composite resin restoration. (05 Mar 2000) |
