Dental mirror device
First Claim
Patent Images
1. A dental mirror comprising:
- a handle portion;
a mirror housing having a bottom support section, the support section having a generally circular shape recess, the recess having an inner edge; and
a shank portion having at a distal end a circular base section comprising of a circular restriction area, the base section further having a spherically shaped ball with split center construction for creating a pair of resilient semi-spheres with a crevice defined therebetween, the semi-spheres capable of being compressed together and seated within the recess of the mirror housing, whereby upon release biasly spring apart to create a releasable tight friction fit capable of angulated movement between the mirror housing and the shank portion, whereby, the mirror housing will be free to angulate in a 360 degree direction for maximum reflection of light beams at the smallest angle of incedence, the angulation only restricted by the contact between the inner edge of the recess and the circular restriction area.

Abstract
A dental mirror having a planar surface encircled by a beveled perimeter. The mirror rotatively mounted upon a spherical support ball, whereby the dentist can continually maintain the correct angle of incidence to capture and reflect light beams from a light source. The planar surface continually being capable of pivoting in relationship to the pressure by the dentist to provide the smallest angle of incidence of reflecting light beams, which is vital to securing the greatest amount of illumination to the surgical area and also in avoiding unwanted distortion of any images in the work area.

3. The dental mirror according to claim 2, wherein the planar mirror is made of glass.
-
4. The dental mirror according to claim 2, wherein the planar mirror is made of a highly polished metal.
-
5. The dental mirror according to claim 2, wherein the planar mirror is made of a lexan plastic material.
-
6. The dental mirror according to claim 2, wherein the support base further includes a raised circular ring and the bottom section of the mirror housing further includes a circular channel defined therein, the circular channel and circular ring in a mating relationship to thereby restrict and secure the mirror angulation.
-
7. The dental mirror according to claim 2, wherein the top section of the mirror housing further includes an outer angular mirror around the planar mirror at a slight angle with the planar mirror, whereby more light will be captured for increased illumination of the working area.
-
8. The dental mirror according to claim 2, wherein the angle of tilt of the planar mirror is further restricted by the bottom section of the mirror housing having a concave surface and the support base having convex base.
-
9. The dental mirror according to claim 8, wherein the concave surface of the mirror housing further having a circular female negative slot and the convex base of the support base further having a circular male positive ridge for friction fitting with the negative slot, thereby allowing the mirror housing to be locked at a particular angulation.
-
10. The dental mirror according to claim 1, wherein the spherically shaped ball is attached to the base section by a screw.
-
11. The dental mirror according to claim 1, wherein the spherically shaped ball and the base section are molded as one piece.
