Particulate marrow cancellous bone.  

A cusp that tends to force food into interproximal areas. A cusp of a tooth that tends to forcibly wedge food into interproximal areas, causing an impaction. Cusp points should be rounded, shortened, or reduced with a dental drill.  

A branching network; chiefly of nerves, lymphatics, or veins. Network, usually said of veins or vascular bundles. A network of either nerves, blood vessels, or lymphatic vessels. Network of intersecting nerves, blood vessels, or lymph vessels (e.g., brachial plexus). A tightly organized network of veins, lymphatic vessels, or nerves. For example, the brachial plexus refers…

The assumption of various distinct structural forms or shapes by a single organism or species. Variations in size or in shape of a given (usually bacterial) species, due to conditions of environment, the pressure of antagonistic substances, or an inherent tendency in some species (e.g., streptobacillus). The condition in which an individual assumes a number…

Abutment swapping. The use of an abutment with a diameter narrower than that of the dental implant platform. This switching moves the implant–abutment junction away from the edge of the platform.  

Implant platform and implant abutment of the same size.  

The junction line between the body of a dental implant and its platform. The localization of the platform edge in relationship to the bone crest determines a crestal, subcrestal, or supracrestal positioning of the implant. The edge of the platform and the implant abutment junction may or may not coincide.  

Prosthetic table, restorative platform, seating surface. Refers to the coronal aspect of a dental implant to which abutments, components, and prosthesis may be connected.  

Plateletrich gel. Autologous preparation derived from whole blood through the process of gradient density centrifugation. Its intended purpose lies in its ability to incorporate high concentrations of growth factors PDGF, TGF‐β1, TGF‐β2, IGF, VEGF, FGF‐1, and fibrin when added to a graft mixture.  

Preparation obtained from whole blood by differential centrifugation. PPP has a relatively high concentration of fibrinogen and is used for autologous fibrin glue preparation, which is employed in surgeries to obtain hemostasis and glue down flaps.
