## Abstract

An apparatus for installing a dental prosthesis. The apparatus includes a guide stent having one or more apertures. One or more implants have a tip and an abutment end connected by a body. A bridge prosthesis has one or more bores defined therein. A retaining fixture is disposed in the bore of the prosthesis. The bridge prosthesis is attached to the one or more implants via engagement between the abutment end of the implant and the retaining fixture.

## Claims

### Claim 1

An apparatus for installing a dental prosthesis comprising:
(a) one or more mini dental implants, wherein each of the one or more mini dental implants has a tip and an abutment end connected by a body, the abutment end having a spherical shape;
(b) a preformed multiple tooth prosthesis corresponding to teeth structure only and having no structure corresponding to gum tissue, the multiple tooth prosthesis having a first surface formed to provide the appearance of a plurality of individual teeth, the multiple tooth prosthesis having a second surface with one or more bores defined therein; and
(c) a hollow mechanical attachment having an O-ring disposed therein, the mechanical attachment disposed in the one or more bores in the multiple tooth prosthesis, the mechanical attachment having a curved interior surface configured and arranged to receive the abutment end of the mini dental implant to attach the multiple tooth prosthesis to the one or more mini dental implants;
(d) wherein the multiple tooth prosthesis is held in position only by frictional engagement of the abutment end of the one or more mini dental implants inside the mechanical attachment in the one or more bores and is detachable from the one or more mini dental implants;
(e) wherein the apparatus is configured such that the abutment ends of the one or more mini dental implants bear substantially all of the downward forces on the mini dental implant from mastication.

### Claim 2 (depends on 1)

The apparatus of claim 1, further comprising a guide stent having one or more apertures, the guide stent being composed of a thermoplastic material configured as a topological imprint formed by vacuum imprinting, and wherein the guide stent functions to direct the positioning of one or more threaded anchors through the one or more apertures.

### Claim 3 (depends on 1)

The apparatus of claim 1 wherein the one or more implants comprise one or more osteoinductive agents, bone graft material, bone substitute material, allograft bone, demineralized bone material, ceramic, coral, collagen and ceramic composite, ossified bone protein, a source of osteogenesis, a fusion promoting substance, a bone growth promoting material, bone, bone derived substances, a demineralized bone matrix, a mineralizing protein, a plasma spray coating, an ossifying protein, bone morphogenetic protein, hydroxyapatite, or genes coding for the production of bone.

### Claim 4

A system for installing a dental prosthesis in a subject, the system comprising:
(a) a guide stent having one or more apertures, wherein the guide stent is composed of a thermoplastic material configured as a topological imprint formed by vacuum imprinting;
(b) one or more mini dental implants for installation in the subject's jaw such that the one or more mini dental implants are aligned with the one or more apertures, wherein the one or more implants have a tip and an abutment end connected by a body, the abutment end having a spherical shape;
(c) preformed multiple tooth prosthesis corresponding to teeth structure only and having no structure corresponding to gum tissue, the multiple tooth prosthesis having a first surface formed to provide the appearance of a plurality of individual teeth, the multiple tooth prosthesis configured to attach to the one or more mini dental implants, the multiple tooth prosthesis having a second surface with one or more bores defined therein; and
(d) a hollow mechanical attachment having an O-ring disposed therein, the mechanical attachment disposed in the one or more bores in the multiple tooth prosthesis, the mechanical attachment having a curved interior surface configured and arranged to receive the abutment end of the mini dental implant to attach the multiple tooth prosthesis to the implant;
(e) wherein the multiple tooth prosthesis is held in position only by frictional engagement of the abutment end of the one or more mini dental implants inside—the mechanical attachment in the one or more bores and is detachable from the implant;
(f) wherein the apparatus is configured such that the abutment ends of the one or more mini dental implants bear substantially all of the downward forces on the mini dental implant from mastication.

### Claim 5 (depends on 4)

The system of claim 4, wherein the one or more implants comprise one or more osteoinductive agents, bone graft material, bone substitute material, allograft bone, demineralized bone material, ceramic, coral, collagen and ceramic composite, bone protein, a source of osteogenesis, a fusion promoting substance, a bone growth promoting material, bone, bone derived substances, a demineralized bone matrix, a mineralizing protein, a plasma spray coating, an ossifying protein, bone morphogenetic protein, hydroxyapatite, or genes coding for the production of bone.

### Claim 6 (depends on 4)

The system of claim 4, wherein the one or more implants include a threaded section, a carrier section, and a self-tapping thread extending to a tip.
