Course Objectives (2 CE Credits)
Achieving a passive fit of the prosthesis is critical when dealing with implant-borne restorations. Thanks to CAD/CAM technology, extremely accurate implant frameworks can now be virtually designed and milled from a solid block of titanium. To optimize the fit of the prosthesis, clinical and laboratory procedures must mirror this high level of accuracy. Outlining a simple procedure for obtaining accurate full-arch implant impressions, this Clinical Tip describes how to:
- Create a sectioned implant verification jig (IVJ)
- Fabricate a custom impression tray
- Lute the sectioned IVJ together intraorally
- Verify the fit of the IVJ
- Take the final impression
- Fabricate the master cast
Even though CAD/CAM implant frameworks have greatly improved and simplified restoring full-arch cases, an extremely accurate impression and master cast are still critical for achieving a passive fit of the prosthesis. Detailed is a highly predictable technique for obtaining accurate full-arch impressions.
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.
