Abstract
Abstract Disclosed is a subperiosteal tissue expander for reconstruction of the edentulous atrophied alveolar ridge of the mandible or maxilla. The expander includes an inflatable tube curved into a "C" shape to match the curvature of the human alveolar ridge, having a layer of reinforcement material on one side of the inflatable tube and tabs for attachment of lines at either end of the inflatable tube. Also disclosed is a method for reconstructing the edentulous atrophied alveolar ridge of the maxilla or the mandible by placing a tissue expander subperiosteally along the alveolar ridge of the maxilla or mandible, inflating the expander to create a subperiosteal channel, removing the expander, and filling the subperiosteal channel with a hard material such as hydroxylapatite.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
78 words
A method for forming an enlarged subperiosteal channel along the alveolar ridge of the mandible or maxilla, comprising the steps of: making an incision in the mucoperiosteum on the alveolar ridge; creating a subperiosteal channel leading from said incision along the alveolar ridge; introducing an expandable tube into said channel; expanding said tube; and leaving said tube in said channel until said mucoperiosteum has stretched or grown so that an enlarged channel remains after removal of said tube.
Claim 2
Independent Claim
78 words
A method for forming an enlarged subperiosteal channel along the alveolar ridge of the mandible or maxilla, comprising the steps of: making an incision in the mucoperiosteum on the alveolar ridge; creating a subperiosteal channel leading from said incision along the alveolar ridge; introducing an expandable tube into said channel; expanding said tube; and leaving said tube in said channel until said mucoperiosteum has stretched or grown so that an enlarged channel remains after removal of said tube.
Claim 3
Dependent Claim
12 words
The method of claim 1, wherein said incision is a midline incision.
Claim 4
Dependent Claim
21 words
The method of claim 2, wherein said channel is a bilateral channel directed posteriorly from said incision toward the retromolar pads.
Claim 5
Dependent Claim
63 words
The method of claim 3, wherein said expandable tube has a tab at one end suitable for attachment of a line, said method further comprising the steps of: introducing a line through said mucoperiosteum into said channel at a point removed from said incision; attaching said line to said tab on said tube; and pulling said tube into said channel with said line.
Claim 6
Dependent Claim
142 words
The method of claim 1, wherein said channel runs from a first end on one of said incision to a second end on the other side of said incision, and wherein said tube has a first tab and a second tab at opposite ends thereof, said tabs adapted for attachment of lines thereto, wherein said method further comprises the steps of: placing a first line through the mucoperiosteum into said first end of said channel, through said channel to said incision, and out of said incision; placing a second line through the mucoperiosteum into said second end of said channel, through said channel to said incision, and out of said incision; attaching said first line to said first tab and said second line to said second tab; and pulling said tube into said channel with said first line and said second line.
Claim 7
Dependent Claim
25 words
The method of claim 1, further comprising the steps of: removing said tube from said enlarged channel; and filling said channel with a hard material.
Claim 8
Dependent Claim
13 words
The method of claim 6, wherein said hard material is a ceramic material.
Claim 9
Dependent Claim
11 words
The method of claim 6, wherein said hard material is hydroxylapatite.
