Abstract
Abstract A dental splint for securing one or more loose, mobile teeth to one or more healthy abutment teeth is provided. The splint utilizes a dental preparation in the lingual or occlusal surface of the teeth and a bar. The preparation should conform to the cross-sectional configuration of the bar with a flat floor, and walls perpendicular thereto. The bar is then chemically bonded to the tooth structure, and a composite covers the bar which is also chemically bonded both to the tooth structure and to the bar. The splint, then, is a unitary structure.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
146 words
A method for providing a bonded intracoronal splint for supporting at least one mobile tooth with at least one abutment tooth comprising the steps of: providing a substantially rigid bar member having a chemically reactive bondable surface; forming a dental preparation in the surfaces of said teeth substantially conforming in cross-sectional configuration to said bar and extending only into the dentin of said teeth, said preparation having a flat floor and walls perpendicular thereto; providing a filled resin composite material and a bonding agent for bonding said bar, composite and tooth material; coating the walls and floor and said bar with said bonding agent; coating the floor of said preparation with said composite; mounting said bar in said preparation on said composite coating; and covering said bar with said composite so that said composite, bar and teeth will be chemically bonded to form a unitary structure.
Claim 2
Independent Claim
146 words
A method for providing a bonded intracoronal splint for supporting at least one mobile tooth with at least one abutment tooth comprising the steps of: providing a substantially rigid bar member having a chemically reactive bondable surface; forming a dental preparation in the surfaces of said teeth substantially conforming in cross-sectional configuration to said bar and extending only into the dentin of said teeth, said preparation having a flat floor and walls perpendicular thereto; providing a filled resin composite material and a bonding agent for bonding said bar, composite and tooth material; coating the walls and floor and said bar with said bonding agent; coating the floor of said preparation with said composite; mounting said bar in said preparation on said composite coating; and covering said bar with said composite so that said composite, bar and teeth will be chemically bonded to form a unitary structure.
Claim 3
Dependent Claim
29 words
The method of claim 1 wherein said bar has a plurality of variably interspersed pin or screw receiving apertures therethrough, each aperture having a diameter of about 0.030±0.010 inches.
Claim 4
Dependent Claim
25 words
The method of claim 2 wherein said bar forms an outwardly opening, longitudinally extending channel with the apertures located between the outwardly extending flanges thereof.
Claim 5
Dependent Claim
58 words
The method of claim 2 further comprising: providing a plurality of screws or pins, each coated with said bonding agent; and securing said pins or screws, each through an aperture into the dentin of said teeth before covering said bar with said composite material so that said pins or screws will be bonded to the teeth and bar.
Claim 6
Dependent Claim
21 words
The method of claim 2 wherein the apertures are mutually spaced about 1/2 millimeter apart along the length of said bar.
Claim 7
Dependent Claim
17 words
The method of claim 2 wherein the apertures are interspersed in non-contiguous groups along the bar length.
Claim 8
Dependent Claim
10 words
The method of claim 1 wherein said bar is non-metallic.
Claim 9
Dependent Claim
23 words
The method of claim 1 wherein said bar is metallic and has no apertures said bar forming an outwardly opening longitudinally extending channel.
Claim 10
Dependent Claim
19 words
The method of claim 1 wherein said bar is non-metallic said bar forming an outwardly opening longitudinally extending channel.
Claim 11
Dependent Claim
17 words
The method of claim 1 wherein the preparation is formed on the occlusal surfaces of said teeth.
Claim 12
Dependent Claim
17 words
The method of claim 1 wherein the preparation is formed on the lingual surfaces of said teeth.
Claim 13
Independent Claim
145 words
A method for providing a bonded intracoronal splint for supporting at least one mobile tooth with at least one abutment tooth comprising the steps of: providing a substantially rigid bar member having a roughened bondable surface; forming a dental preparation in the surfaces of said teeth substantially conforming in cross-sectional configuration to said bar and extending only into the dentin of said teeth, said preparation having a flat floor and walls perpendicular thereto; providing a filled resin composite material and a bonding agent for bonding said bar, composite and tooth material; coating the walls and floor and said bar with said bonding agent; coating the floor of said preparation with said composite; mounting said bar in said preparation on said composite coating; and covering said bar with said composite so that said composite, bar and teeth will be chemically bonded to form a unitary structure.
Claim 14
Independent Claim
145 words
A method for providing a bonded intracoronal splint for supporting at least one mobile tooth with at least one abutment tooth comprising the steps of: providing a substantially rigid bar member having a roughened bondable surface; forming a dental preparation in the surfaces of said teeth substantially conforming in cross-sectional configuration to said bar and extending only into the dentin of said teeth, said preparation having a flat floor and walls perpendicular thereto; providing a filled resin composite material and a bonding agent for bonding said bar, composite and tooth material; coating the walls and floor and said bar with said bonding agent; coating the floor of said preparation with said composite; mounting said bar in said preparation on said composite coating; and covering said bar with said composite so that said composite, bar and teeth will be chemically bonded to form a unitary structure.
Claim 15
Dependent Claim
33 words
The method of claim 12 wherein said bar has a plurality of variably interspersed pin or screw receiving apertures therethrough, each aperture having a diameter of about 0.030 plus or minus 0.010 inches.
Claim 16
Dependent Claim
25 words
The method of claim 13 wherein said bar forms an outwardly opening, longitudinally extending channel with the apertures located between the outwardly extending flanges thereof.
Claim 17
Dependent Claim
59 words
The method of claim 13 further comprising: providing a plurality of screws or pins, each coated with said bodning agents; and securing said pins or screws, each through an aperture into the dentin of said teeth before covering said bar with said composite material so that said pins or screws will be bonded to the teeth and the bar.
Claim 18
Dependent Claim
22 words
The method of claim 13 wherein the apertures are mutually spaced about one half millimeter apart along the length of said bar.
Claim 19
Dependent Claim
17 words
The method of claim 13 wherein the apertures are interspersed in non-contiguous groups along the bar length.
Claim 20
Dependent Claim
10 words
The method of claim 12 wherein the bar is non-metallic.
Claim 21
Dependent Claim
23 words
The method of claim 12 wherein the bar is metallic and has no apertures, said bar forming an outwardly opening, longitudinally extending channel.
Claim 22
Dependent Claim
18 words
