Mindblown: a blog about philosophy.

Device that receives its primary bone support by means of resting upon bone.  

A dental implant that obtains its principal support through sitting on top of the edentulous areas of the alveolar bone. Supplementary retaining screws that enter directly into the bone for the purposes of securing this implant framework to the alveolar bone are referred to as an endosteal dental implant component. If the eposteal framework should…

The tissue serving as the lining of the intraoral surfaces. The junctional form is nonkeratinized, is single or multiple layered, and adheres to the tooth surface at the base of the gingival crevice. The epithelium in the oral cavity is either keratinized or nonkeratinized depending on its location.  

Anatomy term used to describe the surface layer or lining of an organ. In the mouth, it is used to describe the mucosal tissue serving as the lining of the intraoral surfaces. A layer of cells lining internal plant cavities that may secrete resins or gums. One or more layers of epithelial cells, supported by…

Oral epithelium connects to the underlying connective tissue by ridge-like projections of epithelium (rete ridges). The epithelial projections appear as pegs in cross‐section.  

The growth of epithelium over connective tissue during the healing process. The process, either pathologic or part of normal healing, whereby an area of the oral cavity is covered by or converted to epithelium. Healing over a wound by the growing of epithelial cells of the skin. The growth of skin over a wound. The…

A term that describes the intimate relationship between the gingival mucosa and the dental implant. The use of this term implies a close adherence, and suggests a lack of true biochemical connection or attachment between the implant and mucosa.  

Cell that lines hollow organs and glands and makes up the outer surface of the body. Arranged in single or multiple layers, depending on the type, they help protect or enclose organs. Some produce mucus or other secretions, and others have tiny hairs called cilia, which help remove foreign substances, for example from the respiratory…

The mechanism of attachment of the junctional epithelium to a tooth or dental implant, i.e., hemidesmosomes. The link between the reflection of the junctional (gingival) epithelium and the enamel, cementum, or dentin of the tooth.  

Migration of gingival sulcular and junctional epithelia in the apical direction as a result of periodontitis progression. During the healing process after periodontal therapy, the epithelial cells migrate apically, attaching to the root or oral implant surface and preventing connective tissue cell attachment.
