Creating Surgical Guides Using CBCT and Intraoral Scanning
generic STL files may be exported directly from the iTero
user’s account to planning software available to various
services such as Cybermed’s In2Guide. Virtual wax-up
and planning may be done to create surgical guides, with
simultaneous consideration of hard tissue and optimal
restoration location, providing clinicians a higher level of
confidence when placing implants. Final implant restoration
may be done with digital scanning systems such as iTero
using dedicated Inclusive Scanning Abutments, which are
available for a number of the most popular implant systems.
Remarkable advances in implant crown manufacture allow
Glidewell Laboratories to create screw-retained crowns in
a 100 percent digital environment without conventional
models. The clinical example presented in this article
showcases the use of scanning technology to plan implant
placement, create a precise surgical guide in an all-digital
environment, place implant fixtures, and restore these
implants with digital scanning technology and highly
precise all-digital manufacturing technology — all without
the use of a conventional analog model. The promises of
the digital future of dentistry are now here. IM
