Biodegradable, rigid thermoplastic polymer of glycolic acid and the simplest linear, aliphatic polyester used as a material for the synthesis of absorbable sutures and barrier membranes and as a carrier for bone morphogenetic proteins (BMPs). When exposed to physiologic conditions, PGA is degraded by random hydrolysis and apparently also broken down by certain enzymes, especially…

Variety of resin‐ceramic composite materials for use as direct restorative materials or as CAD/CAM indirect restorative materials.  

A type of multifilament braided material made of purified lactides and glycosides used to fabricate absorbable sutures or membranes, or surgical mesh. An absorbable polymer used to manufacture sutures and surgical mesh.  

An abnormal increase in the proportion of red cells in the blood. Abnormal increase in the number of erythrocytes in the blood, often associated with pulmonary or heart disease, or exposure to high altitudes for a long period, but in many cases of unknown cause. Condition of increased numbers of red cells in the blood…

Component connected to the apical part of an abutment to protect the base and allow the laboratory technician to polish the prosthesis and abutment without overreducing the base diameter or rounding the edges. Or an abutment analog or implant analog that is connected to the prosthesis and used to protect the intermediate connection surface during…

Implant surface intentionally made extremely smooth using abrasives or electrical polishing methods. Compare: Turned implant surface.  

A set of vertices in a 3D coordinate system. These vertices are usually defined by X, Y, and Z coordinates, and typically are intended to represent the external surface of an object. Point clouds are most often created by 3D scanners, which automatically measure a large number of points on the surface of an object,…

The furthermost anterior point on the mandible.  

Physiologic process that occurs in all paranasal sinuses during the growth period, causing them to increase in volume. The presence of air-filled cavities in bone, such as the sinuses of the skull. The formation of air-filled cavities, usually in bone (e.g., the paranasal sinuses and mastoid sinuses).  

Polymethylmethacrylate.
