Dental aiming device

Claim 2

A dental aiming device comprising: an alignment member having film holding means at one end and an aligning arm at its other end with a biteplate intermediate thereof, said arm being offset with respect to said film holding means and said bite plate; a film holder slideably adjustable in a vertical direction within said film holding means; an alignment ring adjustably mounted to said aligning arm for slidable movement thereon; a plate holder rotatably mounted to said alignment ring; and an x-ray opaque plate mounted to said plate holder, said plate holder and said x-ray opaque plate each having an aligned centrally disposed aperture therein of identical configuration.

Claim 3

Device of claim 1 further characterized by cover means mounted to said plate holder for supporting said x-ray opaque plate thereto, said cover means having a centrally disposed aperture of identical configuration as said apertures in said plate holder and said x-ray opaque plate and aligned therewith.

Claim 4

Device of claim 2 wherein said x-ray opaque plate is lead, and said plate holder and said cover means rigidly sandwich said lead plate therebetween.

Claim 5

Device of claim 1 wherein each of said apertures is rectangular in configuration.

Claim 6

Device of claim 1 wherein said alignment ring is provided with a mount extending from a peripheral portion thereof, said mount having a plurality of bores therethrough linearly aligned, one of said bores frictionally receiving said arm.

Claim 7

Device of claim 1 wherein each of said apertures is rotatable as a unit by rotation of said plate holder in said alignment ring.

Claim 8

Device of claim 1 wherein said film holder is provided with a plurality of vertically disposed preformed indentations and said film holding means is provided with a projection for engagement with any one of said indentations.

Claim 9

Device of claim 1 wherein said film holder includes a flap which resiliently grasps film, said film being vertically and horizontally adjustable in said film holder.

Claim 10

Device of claim 5 wherein each of said bores is rectangular in configuration.

Claim 11

Device of claim 9 wherein said film holder is provided with a plurality of indentations and said film holding means is provided with a projection for engagement with any one of said indentations.

Claim 12

Device of claim 10 wherein said aligning arm is received in a selected one of said bores, and said projection is engaged in a selected one of said indentations to thereby permit periapical exposures, vertical bitewing exposures and horizontal bitewing exposures of any region of a patient's dentition.

Claim 13

A dental aiming device comprising an alignment member having film holding means at one end and an aligning arm at its other end with a biteplate therebetween, said arm being offset with respect to said film holding means and said biteplate, a film holder slidably adjustable in a vertical direction within said film holding means, an alignment ring adjustably mounted to said arm for sliding movement therealong in a direction parallel to the axis of said ring, means for accomodating any periapical or bitewing exposure of maxilliary or mandibular posterior or anterior teeth without subjecting a patient to unnecessary x-rays, said means including a plate holder rotatably mounted to said alignment ring, and x-ray opaque plate mounted to said holder, said plate holder and plate each having an aligned centrally disposed aperture therein of identical rectangular configuration, said ring having a mount extending from a peripheral portion thereof, said mount having a plurality of bores therethrough and linearaly aligned, said bores being parallel to said axis with one of said bores receiving said arm.

Claim 14

A dental aiming device comprising an alignment member having film holding means at one end and an aligning arm at its other end with a biteplate therebetween, said arm being offset with respect to said film holding means and said biteplate, a film holder slidably adjustable in a vertical direction within said film holding means, an alignment ring adjustably mounted to said arm for sliding movement therealong in a direction parallel to the axis of said ring, means for accomodating any periapical or bitewing exposure of maxilliary or mandibular posterior or anterior teeth without subjecting a patient to unnecessary x-rays, said means including a plate holder rotatably mounted to said alignment ring, and x-ray opaque plate mounted to said holder, said plate holder and plate each having an aligned centrally disposed aperture therein of identical rectangular configuration, said ring having a mount extending from a peripheral portion thereof, said mount having a plurality of bores therethrough and linearaly aligned, said bores being parallel to said axis with one of said bores receiving said arm.
