  • Layer-based abrasive computer tomography for custom denture fabrication
    2010 International Conference on System Science and Engineering, 2010
    Co-Authors: Chong-ching Chang
    Abstract:

    Fixed partial denture produced by conventional method is greatly relied on the skill and experience of Dental Technician. Its quality and accuracy depends mostly on the Technician's subjective judgment. In addition, the manual process involves many procedures which require a long time to complete. Most important, it does not preserve any quantitative information for future retrieval. In this paper, a new device for scanning denture images and reconstructing 3D digital information of Dental model by abrasive computer tomography (ACT) was designed in-house and proposed. The fixed partial denture was then produced by the rapid prototyping (RP) and computer numerical control (CNC) machining methods based on ACT scanned digital information. A force feedback sculptor (FreeForm system, Sensible Technologies Inc., USA) accompany with 3D Touch technology was applied to modify the morphology or the design of denture. It enables the dentist to perform digital manipulation of denture profile with real-time and user-friendly human interactive operation without relying on CAD/CAM Technician or Dental Technician. In this article, the comparison of conventional manual operation and digital manufacture using both RP and CNC machining technologies for denture production was presented. In addition, a digital custom denture manufacturing protocol integrating proposed computer abrasive teeth profile scanning, computer-aided denture design, 3D touchable force feedback feature modification and advanced denture manufacturing techniques were suggested. These proposed methods provide a solid evidence that digital design and manufacturing technologies may become a new avenue for custom-made denture design, analysis, and production in 21st century.

  • A new layer-based imaging and rapid prototyping techniques for computer-aided design and manufacture of custom Dental restoration
    Conference Proceedings - IEEE International Conference on Systems Man and Cybernetics, 2008
    Co-Authors: Ming Yih Lee, Chung-hsien Kuo, Chong-ching Chang, Yen-chen Ku
    Abstract:

    Fixed Dental restoration by conventional methods greatly relies on the skill and experience of the Dental Technician. The quality and accuracy of the final product depends mostly on the Technician's subjective judgment. In addition, the traditional manual operation involves many complex procedures, and is a time-consuming and labour-intensive job. Most importantly, no quantitative design and manufacturing information is preserved for future retrieval. In this paper, a new device for scanning the Dental profile and reconstructing 3D digital information of a Dental model based on a layer-based imaging technique, called abrasive computer tomography (ACT) was designed in-house and proposed for the design of custom Dental restoration. The fixed partial Dental restoration was then produced by rapid prototyping (RP) and computer numerical control (CNC) machining methods based on the ACT scanned digital information. A force feedback sculptor (FreeForm system, Sensible Technologies, Inc., Cambridge MA, USA), which comprises 3D Touch technology, was applied to modify the morphology and design of the fixed Dental restoration. In addition, a comparison of conventional manual operation and digital manufacture using both RP and CNC machining technologies for fixed Dental restoration production is presented. Finally, a digital custom fixed restoration manufacturing protocol integrating proposed layer-based Dental profile scanning, computer-aided design, 3D force feedback feature modification and advanced fixed restoration manufacturing techniques is illustrated. The proposed method provides solid evidence that computer-aided design and manufacturing technologies may become a new avenue for custom-made fixed restoration design, analysis, and production in the 21st century.

  • generalized peripheral neuropathy in a Dental Technician exposed to methyl methacrylate monomer
    Neurology, 1991
    Co-Authors: Michael Donaghy, Geoffrey Rushworth, Jean M Jacobs
    Abstract:

    A 58-year-old Dental prosthetic Technician developed generalized sensorimotor peripheral neuropathy. Neurophysiologic studies showed a generalized sensorimotor neuropathy of axonal degeneration type. Examination of a sural nerve biopsy showed a moderately severe axonal neuropathy with loss of large myelinated fibers and unmyelinated axons. There was evidence of slow ongoing degeneration and considerable fiber regeneration. Electron microscopy showed increased numbers of filaments in a few fibers. These findings show resemblances to the nerve changes caused by another acrylic resin, acrylamide. We suggest that the neuropathy may have been caused by 30 years of occupational cutaneous and inhalational exposure to methyl methacrylate monomer since we excluded other recognized causes of neuropathy.
