Evolution of computer-assisted planning systems used in implant dentistry in the first decades of the 21st century

Digital techniques in dentistry have been developing
rapidly in the past 15 years, irreversibly changing
modern dentistry with the implant dental procedures,
to become one of the most influenced areas of dental
sciences. 3-D implant planning software systems
available since the beginning of the 21st century have
been evolving towards more user-friendly interfaces
and more advanced planning. These new solutions
make it possible to integrate the planning systems
with 3-D printing devices. Authors of the following
paper describe the most important advancements in
the planning systems that allow the merger of 3-D CT
imaging with the soft tissue visualizations acquired
with the intra-oral or lab scanners, thus limiting
indications for the classic double CT scanning
techniques with the use of individual radiographic
guides. The possibility of surgical template production
independent of the software provider itself has also
been described. It may significantly cut the costs of its
production, but might at the same time increase the
risk of potential inaccuracies due to the limitations of
the available 3-D printing devices.
