Pretreatment and aging of zirconia: Effect on different material properties

Zirkonoxid

Zirconia: What influence do different air-abrasion and aging methods have on the flexural strength and phase structure of first- and second-generation zirconia? This question was examined in detail in an investigation conducted by LMU Munich. Metal-free prosthetic restorations have become an essential part of modern treatment concepts. The rapid development of different zirconia ceramics requires in-depth knowledge of their material...

Implant prosthetics (Part 3) – Angulated screw channels for occlusal screw fixation

Implantatprothetik

In implant prosthetics, occlusally screw-retained restorations may reach functional and esthetic limits, for example, if screw channel openings are located in the buccal surfaces or between teeth. In edentulous fixed implant restorations, openings of screw channels may also occur in areas of the reconstructed gingiva. Andreas Kunz, Dr. Insa HerklotzIn Parts 1 and 2 of the series of articles on...

Fracture load of differently veneered implant-supported 4-unit PEEK fixed dental prostheses with a free-end unit

PEEK, Bruchlast

Fracture load of differently veneered implant-supported 4-unit PEEK fixed dental prostheses with a free-end unit Danka Micovic Soldatovic, MünchenUntil today, the most commonly used materials for implant-supported fixed dental prostheses (FDPs) are metal-ceramic and zirconia. Due to shortcomings of both materials (compromised esthetics, allergies on metal or chipping and delamination of the veneering ceramic) and a growing tendency to use...

TEAM Talk “Zirconia”: The key messages

Zirkonoxid

Zirconia was the focus of the second TEAM Talk of the EADT e.V.. The new interactive online format serves the targeted exchange of knowledge. The TEAM Talk comes alive from the participatory principle. The participants are listeners and contributors at the same time. The entertaining online talk is moderated by Carsten Fischer. Zirconia: Question and conclusion The second TEAM Talk focused...

Multiple firings of veneered zirconia restorations: Influence on thermal and mechanical properties

Zirkonoxid-Restaurationen

What influence does a different number of firings of veneering ceramics on a zirconia framework have on the thermal and mechanical properties of these materials? Within an investigation at the LMU Munich, this question was examined in more detail. The picture shows (from top to bottom): specimens fired 2, 4, 6, 8 and 10 times with increasingly visible edge rounding. Justine...

High-speed-sintering of zirconia – relevant scientific findings for the user briefly summarized

High-Speed-Sintern

For some time now, „high-speed sintering" of zirconia restorations has been possible. In this overview, relevant scientific findings are presented briefly and condensed to the essentials.Felicitas Mayinger, Annett Kieschnick, Bogna StawarczykSintering protocols of zirconia with a holding time of approx. 5 – 20 min, a heating rate > 200 °C/min and a final sintering temperature > 1560 °C/min are summarized...

Two-body wear of printed and milled splint materials

Aufbissschienen

How do splint materials produced by different CAD/CAM manufacturing methods (milling process, 3D printing process) differ regarding their abrasion resistance? Felix Schmeiser M.Eng, MunichIn addition to the general stress caused by the masticatory mechanism, splint materials must withstand forces of up to 770 N during malfunction of the masticatory system. Besides subtractive manufacturing with milling machines, 3D printing has already...

Dental 3D printing – an overview

Dentaler 3D-Druck

3D printing: Additive manufacturing is becoming increasingly important in dentistry and dental technology especially for economic reasons. In addition to the processing of metal alloys and ceramics, the focus in dentistry is primarily on the additive processing of resins. Veronika Greil, MünchenWhile in subtractive manufacturing the workpieces are milled or ground from a complete round blank using CAD / CAM-supported...

High-speed sintering of zirconia

What is the influence of high-speed sintering of zirconia on the accuracy (trueness and reproducibility) and fit of restorations? An investigation at LMU Munich addressed this highly topical issue and provided exciting findings. Anja Liebermann, Annett Kieschnick, Bogna StawarczykZirconia is often used in everyday clinical practice for restorations of various types - from single-tooth to multi-unit restorations. The restorations traditionally...
