Abstract:

An improved dental mirror for facilitating the accurate visualization and measurement of structures and distances and for facilitating the assessment of parallelism between non-adjacent teeth. The dental mirror includes an elongated handle having a longitudinal axis and affixed to one end thereof is a mirror frame. The mirror frame supports a planar mirror of rectangular geometry having a perimeter defined by a pair of major parallel edges and minor edges. A series of calibrations are provided along the perimeter of the mirror whereby at least one of the edges is calibrated by lines of demarcation. A plurality of angulations between handle axis and major parallel edge, in the plane of the mirror, is achievable by a rotation mechanism or on a series of fixed angle dental mirrors with different orientations.
