  • Sandblasted, large‐grit, acid‐etched (SLA) implant surface

    A surface treatment that improves surface roughness to enhance osseointegration through greater bone–implant contact (BIC) as well as an increased rate of osseointegration.  

  • Sandblasted implant surface

    Implant surface that has been treated by exposure to silica sand particles propelled under high pressure, thus creating a rough surface texture.  

  • Salivary pellicle

    The rapid formation of an acquired, organic, acellular deposition of salivary and gingival crevicular fluid proteins, on a clean surface, exposed to the oral environment. The thin layer of salivary proteins and glycoproteins that quickly adhere to the tooth surface after the tooth has been cleaned; this amorphous, bacteria-free layer may serve as an attachment…

  • Saliva

    Saliva

    The secretions of the major and minor salivary glands. The clear, viscous fluid secreted by the salivary glands and mucous glands of the mouth. It contains mucins, water, organic salts, and ptylin. Secretion of the salivary glands in the mouth: 1-1.5 litres secreted daily. A dilute solution of the protein mucin (which lubricates food) and…

  • Sagittal plane

    The anteroposterior plane or section parallel to the long axis of the body. An imaginary vertical plane extending from front to back dividing the body into right and left halves. The division of the body along the midline, at right angles to the coronal plane, dividing the body into right and left parts. A vertical…

  • Sagittal axis

    An imaginary anteroposterior line around which the mandible may rotate when viewed in the frontal plane. A line from the front to the back of the body at about waist height. Imaginary line running anterior-posterior, about which frontal plane motion occurs.  

  • Sagittal

    Situated in the plane of the cranial sagittal suture or parallel to that plane. Median line in bilateral symmetry. Plane that divides the body into right and left parts. Like an arrow. Going from the front of the body to the back, dividing it into right and left. To a line from front to back…

  • Saddle pontic

    A pontic with a broad concave faciolingual area of contact with the residual ridge. It is also known as a ridge lap pontic. This type of pontic is known to be uncleanable and results in tissue irritation at the area of contact with the ridge mucosa.  

  • Saccharolytic

    The ability of some microorganisms to catabolize carbohydrates. A substance with the ability to chemically break down sugar.  

  • Sdr

    The developed surface area ratio.
