Marginal fit of full contour monolithic zirconia in different thicknesses and layered zirconia crowns

Journal of International Society of Preventive and Community Dentistry, 2020
Use of monolithic zirconia for fabrication of all-ceramic crowns eliminates several shortcomings of layered zirconia crowns. Long-term success of restorations highly depends on the marginal fit. The crown thickness is among the factors that affect the marginal integrity. Meanwhile, reduced thickness of crowns has several advantages such as preservation

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Aging of monolithic zirconia dental prostheses: Protocol for a 5-year prospective clinical study using ex vivo analyses

Contemporary Clinical Trials Communications, 2016
Background: Recent introduction of computer-aided design/computer-aided manufacturing (CAD/CAM) monolithic zirconia dental prostheses raises the issue of material low thermal degradation (LTD), a well-known problem with zirconia hip prostheses.

Spectrophotometric examination of monolithic zirconia materials

Fogorvosi Szemle, 2023
Introduction: Patients’ demand for perfectly esthetic restorations is unstoppably increasing, however creating naturallooking crowns and FPDs is highly affected by the experience of the dental technician even in the present day. This problem is even more complicated if the abutment is discolored (e.g. obturated).
