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.
