  • (20) In the implant fixed partial denture, stresses induced in the surrounding bone became higher around the posterior abutment and became lower around the premolar retainer than the stresses produced with the natural tooth fixed partial denture.

Contiguous


Definition:

  • (a.) In actual contact; touching; also, adjacent; near; neighboring; adjoining.

Example Sentences:

  • (1) The nuclei in contiguous groups of cells were modeled and analyzed.
  • (2) These data imply that the viral subgenomic mRNAs are composed of leader and body sequences which are non-contiguous on the genome.
  • (3) Close proximity and contiguity of the cut surfaces were important for such growth to occur.
  • (4) The vessel number, the vessel diameter and the distance intervening between contiguous vessels were measured.

  • (12) The Pasteurella haemolytica leukotoxin determinant is composed of four contiguous genes encoded on the same DNA strand and denoted lktCABD, in the order of their genetic organization.
  • (13) Magnetic resonance measurements of left ventricular volume and ejection fraction based on measurements of area and length in a single oblique plane containing the long axis of the ventricle were compared with measurements made by summing the areas of the chamber in multiple contiguous slices.
  • (14) A contiguous panel of markers permitted mapping of the deletion to 17p12-p13.1, the same chromosomal region for which loss of alleles has been shown in tumor specimens from patients with colon cancer, and the same region to which the p53 gene has been mapped.
  • (15) The deformities resulting from premature closure of a coronal, sagittal, metopic, or lambdoid suture can be predicted by the following observations: (1) cranial vault bones that are prematurely fused act as a single bone plate with decreased growth potential; (2) asymmetrical bone deposition occurs mainly at perimeter sutures, with increased bone deposition directed away from the bone plate; (3) sutures adjacent to the stenotic suture compensate in growth more than those sutures not contiguous with the closed suture; and (4) enhanced bone deposition occurs along both sides of a nonperimeter suture that is a continuation of the prematurely closed suture.
  • (16) In these cases of low-grade oligodendroglioma, MR was believed to be superior to CT in providing information needed for radiation therapy planning because of its ability to distinguish tumor and adjacent edema (considered tissue at risk for containing microscopic tumor) from contiguous normal brain.
