| dental implantation, endosseous | Insertion of an implant into the bone of the mandible or maxilla. The implant has an exposed head which protrudes through the mucosa and is a prosthodontic abutment. (12 Dec 1998) |
| dental implantation, endosseous, endodontic | Insertion of a tapered rod through the root canal into the periapical osseous structure to lengthen the existing root and provide individual tooth stabilization. (12 Dec 1998) |
| dental implantation, subperiosteal | The grafting or inserting of an appliance designed to fit over the surface of the mandible or the maxilla, beneath the specialised connective tissue that covers the bone (periosteum). (12 Dec 1998) |
| dental implants | Biocompatible materials placed into (endosseous) or onto (subperiosteal) the jawbone to support a crown, bridge, or artificial tooth, or to stabilise a diseased tooth. (12 Dec 1998) |

| dental impression materials | Substances or combinations of substances used for making a negative reproduction or impression of the teeth and oral structures for the purpose of producing restorations, prostheses, and dentures, including elastomeric materials, dental plasters, metallic oxide pastes, hydrocolloids, silicone base materials, polyethers, polysulfides, and duplicating compounds. (12 Dec 1998) |
| dental impression technique | Procedure of producing an imprint or negative likeness of the teeth and/or edentulous areas. Impressions are made in plastic material which becomes hardened or set while in contact with the tissue. They are later filled with plaster of paris or artificial stone to produce a facsimile of the oral structures present. Impressions may be made of a full complement of teeth, of areas where some teeth have been removed, or in a mouth from which all teeth have been extracted. (12 Dec 1998) |
| dental index | Relation of the dental length (distance from the mesial surface of the first premolar to the distal surface of the third molar) to the basinasal (basion to nasion) length: (dental length ×100)/basinasal length, a system of numbers for indicating comparative size of the teeth. Synonym: Flower's dental index. (05 Mar 2000) |
| dental instruments | Hand-held tools or implements especially used by dental professionals for the performance of clinical tasks. (12 Dec 1998) |
