Introduction: Zirconium restorations are put in place to achieve a better aesthetic appearance that over the years
aesthetically does not satisfy or if there is a shortage of certain teeth to compensate for the space.
Aim: To present the method of making full-featured zirconia and the construction of a vestibular cut-back modeling technique
through a CAD / Design system with complete anatomy-morphological features. The aim is to make a comparison between
these two techniques.
Material and method: The 3Shape program is one of the programs used to design bridges or crowns. Zirconium discs are
used on which the designed bridge or crown through the CAD / Design system is operated. CAD / Design system is a
system used to design the anatomo-morphological characteristics of the bridge or crown that needs to be made.
After the designing, zirconium discs are used for bridge or crown modeling and they are part of the CAD / CAM system. In
the case of full zirconia bridges or crowns after their cutting they are stained with paint, and in the case of cut-back zirconia,
a bridge construction allows designing a certain space on the vestibular surface to place ceramics.
Conclusion: These crowns or bridge are long lasting, naturally lying under the gingiva and showing successful incorporation
in the oral environment. Also, zirconium crowns do not have transparency and do not differ from natural teeth, making it
very difficult to see the difference between the crown and the already existing natural tooth.
