FULL DIGITAL FLOW
THE DIGITAL REVOLUTION
For some time, out of its pioneering and gestation phase, the digitization of prostheses in dentistry is now a consolidated reality that has forever changed the working paradigms in the dental office and in the dental laboratory.
In a nutshell, it is a 360 ° approach that allows you to implement a sequence of work that eliminates numerous sources of possible error in the manufacture of prosthetic products. In particular, the fixed prosthesis, therefore 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, on the environmental temperatures that the impressions and materials undergo without being able to remedy it.
The quality and precision guaranteed by modern systems are now on a par with classic systems, but with considerably greater practicality and flexibility, as well as with many notable advantages for the patient.
3D DIGITAL SCAN
The traditional physical silicone impression is now supplanted 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 software is able to interpret the received images and transform them into a three-dimensional model of the mouth which is saved in the form of a file.
The scanners currently on the market, unlike the first models of a few years ago, 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 Flow Prosthetics, 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 actually 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 a customization with colors that are then fixed with a passage in a special oven (sintering)
