Method for augmentation of the alveolar ridge
First Claim
1. A method of augmenting alveolar ridges in an edentulous patient, said method comprising the steps of:
- (1) providing a charge of particulate dental restorative material;
(2) providing a physsiologically compatible delivery liquid;
(3) mixing said delivery liquid with said charge to form a wetted extrudable semi-plastic mass;
(4) forming a mucoperiosteal tunnel on the lateral aspect of the patient'"'"'s jaw adjacent the alveolar ridge;
(5) depositing said wetted extrudable mass in said tunnel by extruding said mass from a barrel having a bore which is slightly flared from its upper to its lower end for facilitating extrusion by relieving frictional forces between said wettable mass and barrel during said depositing step.

Abstract
The invention comprises a syringe for extrusion of a semi-plastic mass, or a mass having a paste-like consistency. In a preferred embodiment, the syringe is so-designed to permit mixing of two components of a plasticizable mixture within the syringe barrel. The bore of the syringe barrel is flared to facilitate extrusion of the plastic mass therefrom. The parts of the syringe ready for use are packaged in a one-piece tray which serves not only for shipping and storing of the syringe, which may be preloaded with one of the components of the plasticizable mixture, together with the associated syringe parts, but which also serves, when opened for use, as a convenient tray for handling the syringe while mixing the two components of the plasticizable mixture prior to extrusion.
