  • Stress distribution

    The pattern of distribution of stress seen when a load is applied to an object or series of objects. For example, the stress distribution in bone associated with an implant‐supported restoration depends on the number and location of implants, the design of the prosthetic superstructure, and the anatomy of the surrounding bone.  

  • Stress director

    Any device, appliance, or system that redirects the occlusal forces of the stomatognathic system.  

  • Stress concentration

    A location in a subject or a system where there is a remarkably higher stress compared with other areas or points in response to a particular load.  

  • Stress bending

    Load applied to a structure that tends to deform. For an implant, bending stress deforms the long axis of the implant body.  

  • Stress‐bearing region

    Areas of the maxillary or mandibular jaws that are capable of supporting a denture prosthesis. This represents the residual ridge, buccal shelf area, and retromolar pad for the mandibular arch and the residual ridge and the palate for the maxillary arch.  

  • Stress

    Force or load applied to an object. Forcibly exerted influence; pressure. Any condition or situation that causes strain or tension. Stress may be either physical or psychological, or both. The state manifested by the specific syndrome that consists of all the non-specifically induced changes within a biological system; a disruption in body homeostasis and all…

  • Streptococcus sanguis

    Gram‐positive, nonmotile, aerobic cocci that form chains and are found in dental plaque. Also isolated from blood cultures of patients with subacute bacterial endocarditis. S. sanguis is grouped into types I and II. A gram-positive bacterium that can thrive with or without oxygen and exhibits α-hemolysis, belonging to the viridans group. It is present in…

  • Streptococcus oralis

    Gram‐positive, nonmotile, facultative cocci found primarily in plaque of healthy individuals or in healthy sites in individuals with periodontal disease.  

  • Streptococcus mitis

    Gram‐positive, nonmotile, aerobic cocci that tend to form chains and are found in dental plaque. It is difficult to define S. mitis as it does little physiologically and is antigenically heterogeneous. It is often defined by exclusion.  

  • Streptococcus mitior

    Formerly called Streptococcus viridans. Gram‐positive, nonmotile, aerobic, spherical bacteria that form chains and are isolated from the human respiratory tract and from certain clinical conditions. including infective endocarditis.
