<p>A threaded, self-tapping endodontic stabilizer for insertion into the jawbone of a patient's mouth through an aperture in a loose tooth to stabilize the tooth comprises an elongated penetrating member having adjacent its coronal end a head adapted for manual rotation and adjacent its apical end a threaded shaft defining a plurality of lands and grooves. To promote working and generation of perio-stabilizer ligament, a plurality of the grooves have a longitudinal height of at least 0.20 mm. (preferably about 0.25-0.38 mm.) and extend substantially parallel to the longitudinal axis of the threaded shaft for substantially their entire length intermediate the lands, while a plurality of the lands have a shallow recess extending along the peripheral edge thereof.</p> |
