General MicrobiologyPrions are infectious proteins that are highly resistant to destruction by proteases and other methods that typically degrade proteins. This resistance is what allows them to persist in the host and cause disease.

ProsthodonticsExplanation: Monson's spheric theory of occlusion suggests that all cusps and
incisal edges of the teeth should conform to a sphere with an 8-inch diameter,
with the center of the sphere at the glabella, which is the most anterior and
superior point on the midline of the frontal bone of the skull. This concept is
used to achieve balanced occlusion in complete dentures.
