Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
152 words
A dental restoration and die pin jig comprising: a base; means for receiving and holding a dental impression tray in substantially rigid condition above the base; a jig mount situated above the base; die pin setter means cantilever connected to and eccentric of the jig mount and adapted to project in a plane above the base; said die pin setter means comprising a one-piece curvilinear flexible tubular member of yieldable synthetic resinous material having memory and spaced selectively settable means, each joining one end of the tubular member to the jig mount such that adjustment of selectively settable means will change the arc of the tubular member into substantial correspondence in configuration to the arc formed by a dental impression; a plurality of die pin holders, each said holder comprising a bifurcation securing the holder in press fit releasable relation to the tubular member and means from which a die pin depends.
Claim 2
Dependent Claim
152 words
A dental restoration and die pin jig comprising: a base; means for receiving and holding a dental impression tray in substantially rigid condition above the base; a jig mount situated above the base; die pin setter means cantilever connected to and eccentric of the jig mount and adapted to project in a plane above the base; said die pin setter means comprising a one-piece curvilinear flexible tubular member of yieldable synthetic resinous material having memory and spaced selectively settable means, each joining one end of the tubular member to the jig mount such that adjustment of selectively settable means will change the arc of the tubular member into substantial correspondence in configuration to the arc formed by a dental impression; a plurality of die pin holders, each said holder comprising a bifurcation securing the holder in press fit releasable relation to the tubular member and means from which a die pin depends.
Claim 3
Dependent Claim
50 words
The jig of claim 1 further comprising means interposed between the base and the jig mount whereby the jig mount may be pivoted from a position where the die pin setter means is in said plane to a position where the die pin setter means is at least partially erect.
Claim 4
Dependent Claim
27 words
The jig of claim 1 wherein the tubular member comprises a length of hollow yieldable plastic tube arcuately spanning between the selectively settable means without intermediate support.
Claim 5
Dependent Claim
49 words
The jig of claim 3 wherein each die pin holder is of one-piece construction and wherein the bifurcation of each die pin holder comprises a folked section which is forced downwardly upon the plastic tube partially collapsing the tube and retaining each holder by the memory of the tube.
Claim 6
Dependent Claim
41 words
The jig of claim 1 wherein the jig mount comprises means for varying the distance between the selectively settable means for adjusting the location of the ends of the tubular member and thereby varying the curve defined by the tubular member.
Claim 7
Dependent Claim
33 words
The jig of claim 1 further comprising means interposed between the base and the jig mount whereby the elevation of the tubular member in respect to the base may be varied and secured.
Claim 8
Dependent Claim
19 words
The jig of claim 1 further comprising vibrator means in communication with the base whereby impression material is consolidated.
Claim 9
Dependent Claim
104 words
A die pin holder comprising a one-piece elongated clip having a major axis and three ends, the clip comprising: means at one end of the clip for receiving in depending generally axial relation at least one die pin; a body disposed central of the three ends comprising a bifurcated section defining an inverted Y, the apex region of which is adapted to be press fit over die pin setter means; a free normally upwardly directed end comprising a handle for manually gripping the clip to cause the clip to be placed in and removed from said press-fit relation with the die pin setter means.
Claim 10
Dependent Claim
104 words
A die pin holder comprising a one-piece elongated clip having a major axis and three ends, the clip comprising: means at one end of the clip for receiving in depending generally axial relation at least one die pin; a body disposed central of the three ends comprising a bifurcated section defining an inverted Y, the apex region of which is adapted to be press fit over die pin setter means; a free normally upwardly directed end comprising a handle for manually gripping the clip to cause the clip to be placed in and removed from said press-fit relation with the die pin setter means.
