Abstract
Abstract A bridge stabilizing system and method of using same is provided wherein an existing bridge structure may be stabilized directly in the underlying bone structure without the necessity of removing the bridge from its operative engagement with the stubs of natural abutment teeth. To this end, the system comprises a bridge stabilizing implant having a blade edge at one end thereof and a shoulder portion at the other end thereof provided with means for receiving one end of a shaft. The other end of the shaft is adapted to be received in a hollowed out portion of the existing bridge structure. The implant is tapped into the bone and the shaft is placed in its operative position extending into a hollowed-out portion of the bridge structure, after which the hollow is filled with a cold cure acrylic resin to provide operative stabilizing engagement between the implant and the bridge.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
136 words
A bridge stabilizing system adapted to stabilize a hollowed bridge permanently affixed to natural tooth structure in the endentulous span between said natural tooth structure, comprising a stabilizing implant adapted to be embedded in the bone structure underlying said endentulous span and having a blade edge, fastening means one end of which is adapted to be received in a hollow formed in said bridge and the other end of which is adapted to be secured to said stabilizing implant, means on said stabilizing implant remote from said blade edge for engagiNg said other end of said fastening means, and an adhesive filler material for filling said hollow in said bridge and permanently retaining said one end of said fastening means within said hollow, whereby said bridge is permanently affixed to the bone underlying said endentulous span.
Claim 2
Dependent Claim
136 words
A bridge stabilizing system adapted to stabilize a hollowed bridge permanently affixed to natural tooth structure in the endentulous span between said natural tooth structure, comprising a stabilizing implant adapted to be embedded in the bone structure underlying said endentulous span and having a blade edge, fastening means one end of which is adapted to be received in a hollow formed in said bridge and the other end of which is adapted to be secured to said stabilizing implant, means on said stabilizing implant remote from said blade edge for engagiNg said other end of said fastening means, and an adhesive filler material for filling said hollow in said bridge and permanently retaining said one end of said fastening means within said hollow, whereby said bridge is permanently affixed to the bone underlying said endentulous span.
Claim 3
Dependent Claim
24 words
The bridge stabilizing system of claim 1, wherein said engaging means on said implant comprises a recess therein facing oppositely from said blade edge.
Claim 4
Dependent Claim
30 words
The bridge stabilizing system of claim 2, wherein said stabilizing implant is provided with a shoulder portion remote from said blade edge, said recess being formed in said shoulder portion.
Claim 5
Dependent Claim
44 words
The bridge stabilizing system of claim 2, wherein said recess is internally threaded and wherein said one end of said fastening means is externally threaded, whereby said one end of said fastening means is adapted to be threadedly received and retained within said recess.
Claim 6
Dependent Claim
44 words
The bridge stabilizing system of claim 3, wherein said recess is internally threaded and wherein said one end of said fastening means is externally threaded, whereby said one end of said fastening means is adapted to be threadedly received and retained within said recess.
Claim 7
Dependent Claim
18 words
The bridge stabilizing system of claim 1, wherein said adhesive filler means is a cold cure acrylic resin.
Claim 8
Dependent Claim
18 words
The bridge stabilizing system of claim 2, wherein said adhesive filler means is a cold cure acrylic resin.
Claim 9
Dependent Claim
109 words
A method of stabilizing a bridge in the endentulous span between abutment teeth utilizing the system of claim 1 comprising: a. forming said hollow in the tissue-bearing surface of said bridge; b. moving said stabilizing implant into said bone through the tissue along said endentulous span; and then performing the following steps in appropriate sequence: c. inserting said one end of said fastening means into said hollow in said bridge; d. securing said other end of said fastening means to said engaging means on said stabilizing implant; and e. filling said hollow in said bridge with said adhesive filler material, whereby said bridge is permanently affixed to said bone.
Claim 10
Dependent Claim
109 words
A method of stabilizing a bridge in the endentulous span between abutment teeth utilizing the system of claim 4 comprising: a. forming said hollow in the tissue-bearing surface of said bridge; b. moving said stabilizing implant into said bone through the tissue alone said endentulous mucosal span; and then performing the following steps in appropriate sequence: c. inserting said one end of said fastening means into said hollow in said bridge; d. threadedly engaging said other end of said fastening means with said implant in said recess; and e. filling said hollow in said bridge with said adhesive filler material, whereby said bridge is permanently affixed to said bone.
Claim 11
Dependent Claim
115 words
A method of stabilizing an existing bridge in the endentulous span between abutment teeth, utilizing the system of claim 1, comprising the following steps in appropriate sequence: a. forming a hollow in said bridge at the tissue-bearing surface thereof; b. moving said blade through the tissue at the ridge crest adjacent to the tissue-bearing surface of said existing bridge into the underlying bone; c. inserting said one end of said fastening means in said hollow formed in said bridge; d. securing said other end of said fastening means to said bridge stabilizing implant; and e. filling said hollow in said bridge with said adhesive filler material whereby said bridge is permanently affixed to said bone.
