From Intraoral Scan to Final Custom Implant Restoration

Intraoral Scan to Final Custom Implant Restoration - CE Course
Launch Course

Course Objectives (2 CE Credits)

Perry Jones, DDS

Implant cases rely heavily on accuracy and predictability, both of which can be greatly enhanced using the latest computer-aided techniques. In his written case report and accompanying video, Dr. Perry Jones utilizes an intraoral optical scanning system, followed by the CAD/CAM design and milling of all-zirconia custom abutments and a monolithic zirconia bridge, to restore a historically problematic anterior case. His presentation demonstrates the following concepts and technologies:

  • Evaluating implant stability
  • Inclusive® Scanning Abutments (Glidewell Laboratories)
  • iTero™ Digital Scanning System (Align Technology, Inc.; Santa Clara, Calif.)
  • CAD/CAM abutment design utilizing 3Shape DentalDesigner™ (3Shape A/S; Copenhagen, Denmark)
  • CAD/CAM fabrication of monolithic BruxZir® Solid Zirconia anterior bridges (Glidewell Laboratories)

Summary

Digital technology continues to revolutionize the methods of modern dentistry, benefitting every phase of treatment from diagnosis to final restoration. As the long-term success of any implant faces threat from masticatory function, it is critical not only to ensure proper placement, but also to relieve or eliminate undue mechanical stresses that may result from a poorly planned restoration. Taking full advantage of the latest computer-aided techniques as demonstrated here can help to ensure the optimal design of, and precise fit between, the full chain of restorative components, thereby reducing the risk of failure.

CAUTION: When viewing the techniques, procedures, theories and materials that are presented, you must make your own decisions about specific treatment for patients and exercise personal professional judgment regarding the need for further clinical testing or education and your own clinical expertise before trying to implement new procedures.
