Abstract: A security measure status self-checking system which can determine the security measure status in a more simplified and effective manner by focusing on the information leakage measure in the security measures, managing the PC's security measure status and the user's take-out operation status in an integrated and unitary manner, and providing security policy samples. Accordingly, the client computer collects security inventory information and operation log information and transmits the information to the server computer. Further, the server computer stores the security inventory information and the operation log information transmitted from the client computer and determines whether or not the information conforms to the security policy which has been set in advance. The check result is displayed on the server computer and when a policy violation is detected, the manager and the client are notified of that effect.

Abstract: The present invention provides an orthodontic bracket having a bonding surface that has excellent adhesiveness to a tooth surface due to undercuts having been formed by plastic deformation. A bracket 1 that is bonded to a tooth surface using an adhesive for orthodontic treatment is made from a plastic, specifically a polycarbonate or a polyamide. A bonding surface 4 of the bracket 1 is constituted from recessed parts 4a and protruding parts 4b. A projecting member 6 having a-tip part thereof formed into an approximately V-shaped pointed shape is pushed into an outside edge part of each protruding part 4b, whereby the protruding part 4b is pushed outward via a groove 4c. Side walls of each protruding part 4b thus spread out toward the recessed parts 4a, whereby undercuts 5 are formed in the bonding surface 4.

Abstract: An orthodontic supporting structure of the present invention comprises an implant unit which is implantable in a jaw bone and a connecting unit which includes an arm part having a fastening portion. The implant unit has a narrow part in its upper portion. The connecting unit further includes an engaging part having an opening at one end. The engaging part fits on the narrow part of the implant unit. The connecting unit can be attached to the implant unit in a simple way by sliding the engaging part along the narrow part and then crimping far ends of the engaging part.

Abstract: An orthodontic supporting structure of the present invention comprises an implant unit (21) which is implanted in a jaw bone and a connecting unit (22) which includes an arm part (14) having a fastening portion (15). The implant unit (21) has a narrow part (18) in its upper portion (17). The connecting unit (22) further includes an engaging part (26) having an opening (16a) at one end. The engaging part (26) can fit on the narrow part (18) of the implant unit (21). The connecting unit (22) can be attached to the implant unit (21) in a simple way by just sliding the engaging part (26) along the narrow part (18) and then crimping far ends (26b) of the engaging part (26).

Abstract: An orthodontic appliance of the present invention has a combination of a bracket with a hook and a bracket without a hook.The bracket with a hook includes a metal body formed with a groove therein adapted for being engaged with an arch wire and provided with a hook thereon, the hook is integrally formed with the metal body; and a synthetic resin housing for accommodating the metal body therein such that inner surface of the groove is exposed and at least top portion of the hook projects from the synthetic resin housing. The bracket without a hook includes a metal body formed with a groove therein adapted for being engaged with an arch wire; and a synthetic resin housing for accommodating the metal body therein such that inner surface of the groove is exposed.
