FULL DIGITAL FLOW
THE DIGITAL REVOLUTION
Some time having passed since its pioneering and gestational phase, the digitization of prosthetic procedures in dentistry is now a consolidated reality that has forever changed the working paradigms in the dental office and dental laboratory.
In a nutshell, it is a 360° approach that allows to implement a workflow eliminating many sources of possible error in the manifacture of prosthetic products. In particular, fixed prosthetics, meaning the construction of crowns and bridges for covering single and multiple teeth, no longer depends on the dimensional stresses of the impression materials and reproduction of traditional physical models, or on the temperature fluctuations that materials undergo without being able to avoid it.
The quality and precision guaranteed by modern systems are now on a par with classic systems, but with considerably greater practicity and flexibility, as well as with many remarkable advantages for the patient.
3D DIGITAL SCAN
The traditional physical silicone impression is now replaced by a revolutionary technique: 3D digital scanning. A detection device (intraoral scanner) is introduced into the mouth and takes a scan of the teeth, transmitting it to a computer. A special AI provided software is able to interpret the received images and transform them into a three-dimensional model of the mouth which is saved to a file.
The scanners currently on the market, unlike older models, have reached the optimal speed and precision to obtain fixed prostheses of perfect quality.
For the patient, the main advantage lies in the comfort of the scanning session: in fact, he never finds himself having bulky and uncomfortable pastes in his mouth. Furthermore, being able to scan multiple teeth together with ease, there will be a reduction in the number of sessions.
For the dentist, the advantages are many:
-
No difficulty in correcting any detection imperfections - it will be sufficient to delete and rescan the section of the virtual model that presents the defect
-
Considerable ease in the detection of multiple posts - having more than one tooth, the stress due to the difficulty of making precise silicone impressions is considerably reduced, eliminating the risk of having to redo the impression.
3D WORKING IN THE LABORATORY
Within the Full Digital Prosthetic Workflow, the laboratory receives the model file electronically and imports it into the processing system. With a specific CAD software, the technician virtually builds the patient's fixed prosthesis (single tooth or bridge) on screen and then moves on to milling the piece designed with a CAM milling machine.
The prosthesis is mostly cut out of a round wafer-shaped block of zirconia by a five-axis milling machine. The raw piece obtained is further processed by introducing customization with colors that are then fixed with a passage in a special oven (sintering)
