Abstract
Abstract A dental composite carrier and a packaging means for a composite used for posterior restorations in a tooth is provided. The composite carrier comprises a handle having a lever with a jaw on one end, and the package comprises individual incremental portions of composite material contained in ampules, and a number of ampules packaged in a tray. The composite carrier is used to pick an ampule out of the tray, carry it to a tooth, and deliver it into a cavity in the tooth. Optionally, the handle may have a condenser on its opposite end to be used for packing and smoothing the composite in the tooth.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
A package for a composite comprising: a plurality of composite ampules, each said ampule comprising a composite reservoir and a piston, said reservoir being open at one end and having a piston received in a distal end; a tray for storing said ampules having a top part having an upper surface and a lower surface said top part having mounting stations therein, each said mounting station being adapted to receive a composite ampule in said upper surface of said tray and having composite ampules received therein for storage, said mounting stations being adapted to permit easy removal of said ampules therefrom when said ampules are used.
Claim 2
Dependent Claim
106 words
A package for a composite comprising: a plurality of composite ampules, each said ampule comprising a composite reservoir and a piston, said reservoir being open at one end and having a piston received in a distal end; a tray for storing said ampules having a top part having an upper surface and a lower surface said top part having mounting stations therein, each said mounting station being adapted to receive a composite ampule in said upper surface of said tray and having composite ampules received therein for storage, said mounting stations being adapted to permit easy removal of said ampules therefrom when said ampules are used.
Claim 3
Dependent Claim
34 words
The package for a composite according to claim 1, wherein said tray comprises a top part and a bottom part, said top and bottom parts being adapted to snap together in a sealing manner.
Claim 4
Dependent Claim
28 words
The package for a composite according to claim 1 in which said mounting station is adapted to hold said ampule in said tray in a substantially closed environment.
Claim 5
Dependent Claim
32 words
The package for a composite according to claim 3 in which said mounting station in said top part of said package is adapted for contact with said bottom part of said package.
Claim 6
Independent Claim
201 words
A method for depositing a composite comprising the steps of: (a) prepackaging composite within a composite ampule comprising a reservoir having a single hole therethrough, a collar on said reservoir, and a piston extending from said hole in one end of said reservoir, said reservoir having an open end; (b) distributing a plurality of said composite ampules in a mounting stations in a tray whereby said ampule is held upright in said tray for storage with said piston extending upward; (c) picking up an ampule from said tray using a composite carrier having an elongated handle having an elongated lever pivotally attached thereto, said lever having one end comprising a jaw having a pair of J-bars adapted to hold said collar; and a ram adapted to press said plunger; (d) carrying said composite ampule from said tray to a tooth to be filled with said composite using said composite carrier; pressing said composite reservoir against a tooth and moving said lever, thereby causing said handle and lever to pivot relative to each other and said ram to press said piston, said piston forcing said composite to exit from said open end of said reservoir; and depositing said composite to said tooth.
Claim 7
