CLINICAL CASE REPORT<br />
Summary<br />
Digital scanning technology used in conjunction with CBCT<br />
scanning can offer a high level of confidence to practitioners<br />
both in terms of implant placement and implant restoration.<br />
This case demonstrated the merged file, “crown down” planning,<br />
virtual implant placement and tooth-supported surgical<br />
guide design that is possible using CAD software. The unique<br />
customization features of 3-D printing technology allowed<br />
for the creation of a tooth-supported surgical guide in a 100<br />
percent digital environment without the use of stone modeling.<br />
The custom provisional restorations demonstrated the<br />
accuracy of the tooth-supported surgical guide because they<br />
were delivered immediately at the time of implant placement<br />
and required no adjustments. Open-source Inclusive Scanning<br />
Abutments used with the NobelReplace implant system<br />
demonstrated that the actual implant position data could<br />
be accurately captured using the chosen intraoral scanning<br />
technology (iTero). The generated STL files could then be directly<br />
sent to the lab for the design and milling of the screwretained<br />
all-zirconia crowns.<br />
As technology races forward, the current challenges of<br />
developing higher levels of accuracy and consistency are<br />
being addressed, providing clinicians with an increased<br />
level of confidence for implant placement and restoration.<br />
This case, but one example of the growing possibilities,<br />
demonstrates just how far we have come! IM<br />
