The One-crown-one-time Concept: The Benefits and Limitations of Digital Technology for Fixed Implant Reconstruction (LM-1)

  Noon - 1:30 pm

Irena Sailer, DDS, MS

The one-crown-one-time concept encompasses the immediate restoration of osseointegrated implants at the time of the second stage surgery, i.e. the abutment connection surgery. The basic aim is to avoid multiple disconnections of the peri-implant soft tissue attachment during the implant restorative phase, which normally occur at the conventional procedures at healing abutment connection, impression taking and the insertion of final restoration.

In this new concept an optical impression is taken at time of the second stage surgery, and a monolithic restoration is fabricated the same day in-office with aid of a CAD/CAM procedure. The restoration is inserted in the same session and not removed any more. It is hypothesized, that this concept is more efficient than the conventional step-wise approach, and that less bone and soft tissue remodeling and retraction will occur due to the protected integrity of the soft tissue attachment.

Upon completion of this presentation, participants should be able to: 1) discuss the workflow of the one-crown-one-time concept; 2) evaluate biologic effects; and 3) discuss the different material options for the restorations and their effect on the soft tissue health and aesthetics.
