Total Claims: 4
Claim 1
Independent Claim
204 words
An occlusion device for use in examination of occlusion of artificial dentures comprising: a first holder having a substantially U-shaped groove for securing therein a first of two artificial dentures, a second holder having a substantially U-shaped groove for securing therein a second of the two artificial dentures, a supporting device having two parallel legs and a beam member, said beam member being connected at corresponding end portions of said legs, means for pivotally connecting said supporting device to said first holder, and means for pivotally connecting said supporting device to said second holder, said first holder having a denture holding plate and a base plate detachably connected to said denture holding plate, said denture holding plate having said U-shaped groove, said base plate having two parallel grooves on one surface thereof, said beam member of the supporting device having two rods projecting outwardly and having a substantially spherical member at a projected end of each of said rods, said spherical members being nested in predetermined positions within said parallel grooves such that said first holder is pivotally engaged with said rods, said second holder having a denture holding plate and a base detachably connected to said denture holding plate of the second holder.

Claim 3
Dependent Claim
22 words
The occlusion device according to claim 1, in which said beam member is adjustably engaged with said end portions of said legs.
Claim 4
Dependent Claim
125 words
The occlusion device according to claim 1 or 2, in which each of said legs has a round shaped end and an offset portion adjacent said round shaped end forming a shoulder, said offset portion having a depression, said base of said second holder having two cut-out edges for pivotally engaging said legs therewith, said cut-out edges each having a slightly curved slant portion and a spring-biased projection at said slant portion, whereby when said second holder is pivoted at right angles relative to said supporting device, said projection is fitted into said depression with said shoulder being in abutment against a plane of said base of the second holder, thereby maintaining a right angled position of said second holder relative to said supporting device.
