Instrument used with or without abrasives to improve the adaptation of two opposing surfaces. In the laboratory, an instrument, often rotating, used to remove casting irregularities by means of grinding or polishing.    

To cover, fold over, or lie on top of, as in the ridge lap of an artificial tooth that covers the residual ridge.  

The area of a dental cast that denotes the end of the replicated anatomic surface of the mouth and the beginning of a border of the cast.  

A sharp, piercing, cutting, knife‐like pain that is usually intermittent.  

A high molecular weight glycoprotein composed of three polypeptide chains that are organized in a cross‐like manner; functional domains of this molecule have affinity for cell surface receptors and extracellular matrix components. Large, non-collagenous glycoprotein with antigenic properties. It is localized in the basement membrane lamina lucida and functions to bind epithelial cells to the…

Layered material. In dentistry, a thin layer or veneer of restorative material applied to the surface of a tooth, usually for cosmetic purposes. (In leaves) with an expanded blade (as opposed to with a grass-like leaf). A packaging material consisting of two or more films bonded together to achieve better functional protection in such terms…

Connective tissue that is highly vascularized and lies beneath the basement membranelining the epithelium; vascularized connective tissue layer of mucous membranes. The connective tissue of mucous membranes containing, e.g., blood vessels and lymphatic tissues.  

The sheet of compact bone that forms the tooth alveolar wall or tooth alveolus. A radiographical term describing the compact bone (alveolar bone proper) that surrounds the roots of teeth. In a state of health, it appears on a radiograph as a dense radiopaque fine.  

One of the thin layers or flat plates of a larger composite structure, such as bone or tissue. Expanded part of a leaf blade or perianth. A thin plate or flat layer. A thin membrane. A side part of the posterior arch in a vertebra. Laminae, thin membrane or plate-like structure, as the two parts…

Adult, mature bone consisting of 3–5 μm‐wide layers of mineralized collagen fibrils. The orientation of fibrils changes from layer to layer; this construction is often compared with that of plywood. It appears birefringent in polarized light and is found in mature cortical as well as trabecular bone.
