| 19. A dental imaging system, comprising:
(a) means for projecting a plurality of sequential patterns toward a dental item, each of the plurality of sequential patterns
including a plurality of distinguishable curvilinear lines, where a first pattern includes a first number of distinguishable
curvilinear lines, and a subsequent pattern includes a second number of distinguishable curvilinear lines, wherein within
a pattern each curvilinear line is associated with a region that is non-rectangular and that does not overlap with a region
associated with an adjacent curvilinear line;
(b) means for capturing light reflected from a surface of the dental item;
(c) means for determining data points associated with characteristics of the surface according to the captured light reflected
from the surface; and
(d) means for displaying the a three-dimensional representation of the surface of the dental item according to the data points.
