Abstract
Abstract A system for protecting oral tissue or retaining an object at a location in the mouth, consisting of a body of polymeric material extending from a tooth and over the tissue or location and a retaining means which attaches the material to the tooth. The object might be a medication delivery device, and, in particular, a medicated strip which can be inserted into a periodontal pocket. The retaining means might be a fixture tied to or adhesively bonded to the tooth, or the material might be directly adhesively bonded to the tooth. The polymeric material would be specially formulated to suit this application.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
97 words
An oral pack retention system for use in covering a location in the mouth which is adjacent a tooth, comprising: (a) medication delivery means adapted to be placed at said location for delivering medication to the location, (b) a mass of pack material adapted to be placed against said medication delivery means and said tooth for retaining the medication delivery means in position with respect to the location, and (c) connecting means for connecting said mass of pack material to said tooth so that said mass of pack material remains in said medication delivery means retaining position.
Claim 2
Dependent Claim
97 words
An oral pack retention system for use in covering a location in the mouth which is adjacent a tooth, comprising: (a) medication delivery means adapted to be placed at said location for delivering medication to the location, (b) a mass of pack material adapted to be placed against said medication delivery means and said tooth for retaining the medication delivery means in position with respect to the location, and (c) connecting means for connecting said mass of pack material to said tooth so that said mass of pack material remains in said medication delivery means retaining position.
Claim 3
Dependent Claim
33 words
An oral pack retention system as recited in claim 1, wherein the medication delivery means is a thin strip, the location is a peridontal pocket, and the strip is placed in the pocket.
Claim 4
Dependent Claim
27 words
An oral pack retention system as recited in claim 1, wherein the medication delivery means forms a differential barrier which encourages desired repair and discosurages undesired repair.
Claim 5
Dependent Claim

An oral pack retention system as recited in claim 1, wherein the connecting means comprises a separate connector which is attached to said tooth with adhesive.
Claim 8
Dependent Claim
22 words
An oral pack retention system as recited in claim 1, wherein said mass of pack material is adhesively bonded to said tooth.
Claim 9
Dependent Claim
34 words
An oral pack retention system as recited in claim 7, wherein a portion of the tooth is coated with a release agent to prevent adhesion of said mass of pack material on that portion.
Claim 10
Dependent Claim
56 words
An oral pack retention system as recited in claim 1, wherein a blocking mass is positioned in an interdental space to prevent contact between a mass of said pack material which is placed on one side of the tooth and a mass of said pack material which is placed on the other side of the tooth.
Claim 11
Dependent Claim
27 words
An oral pack retention system as recited in claim 1, wherein said mass of pack material is formed of a composite of formable material and fiberous material.
Claim 12
Dependent Claim
36 words
An oral pack retention system as recited in claim 1, wherein the mass includes microfibers treated to increase their adhesion with the rest of the mass and to thereby increase the tensile strength of the mass.
