Patient communication: Change your perspective of the patient
Patient communication: In modern dentistry, in addition to professional competence, communication with patients is of great importance. Effective communication makes it possible to understand patients' concerns, provide them with relevant information and involve them in decisions. It is important to understand clinical, social and emotional needs and to be able to adapt to them. In this article, MDT Marie...
3D printed resin restorations – A question of bonding?
3D printed resin restorations … The ongoing innovations in the field of additive manufacturing are opening up further clinical applications in dentistry. The 3D printing technology now presents aesthetic tooth-coloured restorations that can be produced quickly and material-saving. Valerie Lankes, LMU MunichLeading dental printing technologies include photopolymerisation-based stereolithography (SLA) and digital light processing (DLP). This is preceded by computer aided design...
Pretreatment and aging of zirconia: Effect on different material properties
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
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
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
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
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...
Sharing is caring: Der TEAM-DAY 2022 in Berlin

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