Abstract: A dental implant is specifically designed to properly distribute the forces exerted on the bone by the implant and to foster optimum osteal and/or fibro-osteal integration of the implant with the bone, thereby to improve the quality and longevity of proper implant function. The shaping and location of various surfaces of the implant are specifically designed to minimize both under- and over-stressing of the bone which leads to failure, and to maximize the formation and advantageous functioning of a peri-implant ligament, direct bone apposition, or combinations thereof. Novel structure may be provided so that heads of different shapes and inclinations can be selectively used with the implant to meet the patient's individual physiologic requirements, while at the same time facilitating submerged healing.

Abstract: An electroconductive dental implant is permanently imbedded in the jawbone of the subject, with a portion thereof extending into the oral cavity which is connected to a current source to act as a cathode. A second electroconductive electrode is non-permanently affixed to the skin of the subject, preferably at the ear, and connected to the source to act as an anode. The direct current applied to the implant and the electrode is preferably regulated so as to maintain a substantially constant current level throughout the application thereof. A continuous current, preferably of 200 microamperes or less is applied intermittently for relatively short periods not exceeding approximately one hour in duration. In this manner, osteogenic activity in the bone structure adjacent to the contours of the dental implant is stimulated in order to increase the rate of the normal healing process.

Abstract: 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.

Abstract: The disclosure relates to improvements in an assembly for taking a continuous X-ray picture of the dental arch of a human being, wherein a support base is supported by a wall construction so as to be either vertically slidable or fixed in position, thereby utilizing space much more effectively and improving the appearance of the assembly, and eliminating for an operator or a patient any problem regarding movement of the feet on taking the X-ray picture.
