“…The great disadvantage of these pivots was that they absorbed the fluids they came in contact with, swelling and leading in time to fracture of the dental root on which they were inserted. (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13) Towards the end of the 19th century, metal and wooden post and core were dethroned by the Richmond crowns, which were a cast piece containing both the pivot and the dental crown, which this time was much more aesthetic, with a ceramic component. The advantages of this system were that they significantly improved the adaptation of the crown to the tooth.…”

Post and core devices are elements that contribute to the complete restoration of the coronary abutment, over which the final prosthetic restoration will be created. Their role is to retain the coronary portion of the restoration and to protect the remaining coronary structures. The retention function is dictated by the major indication of the method, massive coronary destruction that does not provide conditions for coronary aggregation of the restoration. Thus, this material is approaching two unique methods of making post and core devices totally metallic and/or hybrid (metal + totally ceramic component), using both classical technology, modern technologies, but also combinations of them.

“…Specifically, providing rigidity to the coronary device, prevents deformation of the crown edges and degradation of cement. (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13) Post and core devices prolong the longevity of the tooth in the dental arch, giving them a satisfactory prognosis.…”

“…In fact, there is a real substantial improvement in the quality of life among these patients. (1)(2)(3)(4)(5)(6)(7)(8)(9) Dental crowns or bridges can be cement-retained or screw-retained to dental implants. Both options have advantages and disadvantages.…”

With the help of dental implants, an oral rehabilitation can be performed not only very complex, but also very complete of various types of edentulous spaces. After insertion of the dental implants, they can be subsequently prosthetically restored through a wide range of implant-supported prosthetic restorations. In this material, we tried to highlight some particular aspects from the point of view of the laboratory stages of dental technique, which intervene in the technological flow of making implant-supported prosthetic restorations from ceramic masses on Zirconia structure.

“…In our previous studies [10,15,16] we found that samples with high concentrations of compounds or nanomaterials in lymphocyte culture cannot be used for genotoxicity assessment because they exceed the maximum allowed concentrations for a correct assessment without false positive results. There is also agglutination and precipitation of the culture.…”

(1) Background: The development of a biocompatible material for direct additive manufacturing of maxillofacial extraoral prosthesis is still a challenging task. The aim of the present study was to obtain a photocurable PDMS, with nano TiO2 inclusions, for directly 3D printing of extraoral, maxillofacial prosthesis. The biocompatibility of the newly obtained nanocomposite was also investigated; (2) Methods: 2.5% (m/m) titania nanoparticles (TiO2) oxide anatase and a photoinitiator, benzophenone (BF) 4.5% were added to commercially available PDMS for maxillofacial soft prostheses manufacturing. The three different samples (PDMS, PDMS-BF and PDMS-BF-TiO2) were assessed by dielectric curing analysis (DEA) based on their viscosities and curing times. In vitro micronucleus test (MNvit) was performed for genotoxicity assessment and three concentrations of each compounds (2 mg/L, 4 mg/L and 8 mg/L) were tested in duplicate and compared to a control; (3) Results: The nanocomposite PDMS-BP-TiO2 was fully reticulated within a few minutes under UV radiation, according to the dielectric analysis. PDMS-BF-TiO2 nanocomposite showed the lowest degree of cyto- and genotoxicity; (4) Conclusions: In the limits of the present study, the proposed ex situ preparation of a PDMS-BP-TiO2 offers an easy, simple, and promising technique that could be successfully used for 3D printing medical applications.
