Abstract
The invention comprises an assortment of plunger-type syringes for the surgical implantation of granular ceramic substances such as hydroxyapatite, whitlockite and alpha alumina during alveolar ridge augmentation and repair. The barrels of the syringes, which are inserted into the patient's periosteal and gum tissue, have various lengths and radii of curvature and various degrees of tip bevelling, such that the surgeon can select the barrel configuration that most closely complies with the contours of the particular alveolar ridge portion upon which the augmentation surgery is to be performed in a particular case. The surgery can thus be performed with fewer and smaller incisions, less tissue trauma, lower risk of accidental tearing and puncturing of tissue, and lower risk of infection than possible with the apparatus and methods known to the prior art.
