Abstract:
Technological advancement has played an important role in several areas, including
dentistry. The introduction of CAD/CAM (Computer-Aided Design and Manufacturing)
technology since the 1950s has transformed the routine of clinical practice. Before,
the process of producing prostheses was exclusively manual and time-consuming.
Today, with the use of digital tools, the time needed to manufacture prostheses has
been reduced, which also reduces the number of consultations required by thedentist. With the advancement of technology and the search for excellence in
treatments, rapid prototyping (PR) has become a viable practice in dentistry, with
emphasis on the use of imaging tests, especially computed tomography. This feature
allows for an accurate analysis of the patient's anatomy and enables the simulation
of procedures in biomodels, which contributes to the optimization of treatment.
Currently, there are a variety of 3D printers that use different technologies, and, with
the advancement of this process, it becomes essential to compare the properties of
temporary prostheses manufactured with 3D printers with those made from
traditionally used materials. This study aimed to compare the properties of dental
crowns made using different 3D printing techniques. It allows us to conclude that
additive manufacturing technologies are already a reality in dental practice. 3D
printing has enabled the fast and fully digital production of study and work models,
surgical guides, casting patterns, individual trays and interocclusal plates, significantly
reducing the occurrence of failures resulting from manual interventions.
