Alloplastic material made of hydrosoluble monomer, which can polymerize under various circumstances at low temperatures. It can be used to prepare various hydrogels to immobilize proteins or cells for grafting purposes.  

Primarily insoluble or partially soluble amorphous and crystalline calcium phosphate coating applied to the surface of an implant, intended to enhance osseointegration.  

A composition of calcium and phosphate in physiologic ratios to provide a dense, nonresorbable, biocompatible ceramic used for dental implants and residual ridge augmentation.  

Method of grafting in which granules of hydroxyapatite can be added to chips of autogenous bone to obtain the desired shape and compromise or delay resorption.  

High‐water prosthesis. A screw‐retained, metal‐resin, implant‐supported, fixed complete denture. The term “hybrid” implies a combination of a metal framework with a complete denture (prefabricated resin teeth and heat‐polymerized resin). The term “high‐water” refers to the design of this prosthesis using long standard abutments with several millimeters of space between the prosthesis and the underlying mucosa…

An endosseous, root‐form dental implant, with different surface geometries or textures at different levels.  

Slang for any modification or alteration in the usual form of a dental prosthesis.  

The immune response mediated by the secretion of immunoglobulins (antibodies) produced by activated B cells (plasma cells) against antigens. Also known as antibody‐dependent immunity. The immune system response consisting of the soluble blood serum components that fight an infection (e.g., antibodies, complement proteins, cecrophins, etc.). Immune response maintained by antibodies; antigens stimulate the production of…

The human major histocompatibility complex composed of both MHC class I and MHC class II molecules, present in all nucleated mammalian cells. Primarily responsible for graft rejection between individuals. A very complex array of six proteins that cover the surface of leukocytes (and the bone marrow cells that produce leukocytes). These HLA are usually different…

A RNA virus that exists as two major types, HIV‐1 and HIV‐2. The genetic material is in the form of messenger RNA and is classified as a retrovirus. The targets of infection of HIV are primarily the T4 helper (CD4+) lymphocytes. A retrovirus that can lead to acquired immunodeficiency syndrome (AIDS), a condition in humans…
