RELATIONSHIP BETWEEN DENTAL MATERIALS IN USE IN THE DIGITAL FIELD
By Matteo Neroni
During the period in which I ran the laboratory in Belfast, several times, I found myself using different types of materials, always looking for the best functional and aesthetic relationship between them.
The case that will be presented in this article is the perfect example of how using 4 types of materials can coexist side by side, without compromising aesthetics and functionality.
As in any case I dealt with, everything is set through a detailed analysis of the physiognomy, facial conformity and vertical dimension of the relationship between the two jaws.
In the above case, 4 types of materials and an aesthetic and functional test in 3D printing have been used.
• Zirconia
• Porcelain
• Composite
• Acrylic resin
Regarding the upper part of my reconstruction, I used a mobile prosthesis approach, because the patient could not put implants (fig.1).
In the lower part, in this case an A04 was chosen (fig.2).
Because of this choice of completely different materials, the teeth chosen for the mobile prosthesis are individual millings made of zirconia, to have the same degree of friction. Certainly, the first problem would have been the heaviness of the prosthesis itself, but following all the protocols and taking an excellent dental impression made us obtain a perfect suchtion, so eventually there were no problems with prosthetic displacement (Fig.3, 4, 5).
Regarding the lower rehabilitation (A04), I adopted the same protocol developed and illustrated in the previous article in September.
I left the composite part to my colleague to try making the difference between composite and porcelain as similar as possible.
Using his best abilities, he was able to solve this problem of difference.
Like every finalizer, I used some composite stains to mask the difference between the materials and I think I have succeeded.
Constructive criticisms, observations and different points of view are accepted for both the design and the finalization of the product.
