A system and method of operating a storage system is provided. The storage system includes a tape cartridge having a magnetic tape medium and a tape drive for reading and writing data to the magnetic tape medium of the tape cartridge. Performance data associated with specific operating loci (e.g., bands, directions, tracks, segments, etc.) of the tape drive and tape medium are collected, analyzed, and stored, allowing for analysis and detection of trends over time. In one example, tape usage events are monitored and when they cross a threshold the system may remove particular tapes in a preventative maintenance approach to reduce system outage. Performance data is collected and analyzed with a portion of the performance data being saved to emulated medium auxiliary memory (EMAM) on the magnetic tape, and a portion of the of the performance data saved in non-volatile storage in the drive.

A system and method by which an orthodontic appliance is automatically designed and manufactured from digital lower jaw and tooth shape data of a patient provides for preferably scanning a model of the patient's mouth to produce two or three dimensional images and digitizing contours and selected points. A computer is programmed to construct archforms and calculate finish positions of the teeth, then to design an appliance, preferably including archwires and brackets, to move the teeth to the calculated positions. The lower teeth are positioned at their roots on an arch defined by the lower jaw bone, and the arch is modified to best fit the tooth tips on a smooth curve. Upper archforms are constructed for the upper teeth. Then, machine code is generated and appliances are automatically produced that will straighten the teeth of the patient. Custom placement jigs are also automatically designed and fabricated and are provided with the custom appliance to position the appliance on the patient's teeth.
摘要:
Orthodontic appliance placement jigs are provided positioning and orienting the appliance at connection points on the teeth of a patient, particularly for positioning brackets against the surfaces of the teeth so that they can be bonded thereto. The jigs are each provided with a surface conforming to the contour of the tooth to which they are to be mounted. Another surface of the jig engages the bracket to hold it in the proper position and orientation for mounting to the tooth and spaced in relation to the contour surface to precisely locate the jig on the tooth. The jigs are particularly useful in positioning brackets of custom appliances designed to the individual anatomy of the patient, and requiring custom positioning of the brackets on the teeth. The jigs are formed with numerical controlled machinery that develops jig forming instructions from digitized tooth shape data and from digital representations of the tooth finish positions and appliance design. The jig forming instructions are preferably derived from the same data and digital information from which the tooth finish positions and custom appliance geometry are calculated.

Aspects of a distalizer and method of assembling a distalizer are provided. The distalizer comprises an arm including a mesial element at one end of the arm, a ball member at another end of the arm, and a distal element which encloses the ball member without deformation of the distal element. The mesial element has a first base for attachment to a canine or bicuspid, and the distal element has a second base for attachment to a molar. To assemble the distalizer, the arm with the mesial element and the ball member is provided, and the ball member is enclosed in the distal element without deformation of the distal element. Alternatively, the mesial and distal elements are additively manufactured simultaneously with the arm including the ball member, and the ball member is enclosed in the distal element without deformation of the distal element during the additive manufacturing.

An orthodontic bracket and ligature are provided in which the bracket, in the preferred embodiment, includes a cylindrical post, spaced from a bracket base to extend horizontally parallel thereto, and having an archwire slot therein. A spring material ligature band, naturally coiled and secured to a plastic installation strip, is pulled around the post of the bracket until a hooked trailing terminal end of the band catches on the bracket, pulling it loose from the strip, and allowing it to snap around the post to hold and confine the archwire in the slot. Different width ligatures seat to different positions on the post to allow the wire to be held to selected tightnesses in the slot by selection of the ligature.

A method and apparatus for accurately positioning and orienting an orthodontic appliance relative to individual teeth of a patient is provided, preferably in the form of a pivot action jig, preferably of two parts pivotally linked together. Preferably, one part releasably engages an orthodontic bracket relative to a pivot axis at which the two parts are connected, preferably by fitting between spaced vertical tie wings of the bracket with a blade fitting in a bracket slot. The second jig part []includes a tooth-engaging surface configured to the shape of the crown of the tooth. Where the bracket itself is configured to pivotally attach to the jig, the jig may be formed of only the tooth engaging part. Preferably, the tooth-engaging surface uniquely fits over the occlusal end of the crown and includes a slight over center end, opposite the pivot connection, and may include a three-dimensional cap. A bracket is positioned in the jig, the assembly of the jig and the bracket is brought against the labial or lingual side of the crown of the tooth, and the tooth engaging part of the jig is pivoted to move the tooth-engaging surface gingivally into a unique position and orientation against the crown. This uniquely positions the bracket in a position where it is bonded to the tooth. When the bond has hardened, the tooth engaging part is pivoted occlusally away from the tooth and the jig is disconnected from the bracket.

The lower teeth are positioned at their roots on an arch defined by the lower jaw bone, and the arch is modified to best fit the tooth tips on a smooth curve. Then upper archforms are constructed for the upper teeth. Crown long axes of the teeth are derived and preserved in the treatment which places all lower teeth but the cuspids in a plane and fits the occluding teeth to them. Overlaps for the upper incisors and for cuspid rise are calculated.

Contours of a patient's teeth are digitally determined from individual teeth of a model of the patient's mouth provided by an orthodontist, preferably by scanning individual teeth in a lingual-facial plane on the model with a mechanical probe. Tooth prominence parameters including tooth-gum intersections, mesial cusp tips or lingual and facial incisal edge points, and groove/ridge locations are selected on the contours. Tooth long axes are derived therefrom in the contour plane through the gum intersection and incisal edge/cusp tip midpoints and the contours are oriented to in the plane to predetermined inclination angles. From these, calculations are made to locate brackets on the contours and determine geometry of slots to cut in the brackets for disposition of a curved archwire in a horizontal plane so as to incline the axes and position the tooth parameters as desired relative to each other when the brace is installed as calculated, using a mold of the brace and model and/or written instructions provided with the brace, and without the need for the orthodontist to bend the archwire. The bite resulting preferably places lower buccal cusps in upper marginal ridges on bicuspids and molars.
