While there have been significant improvements in composites as well as adhesive systems, certain fundamental prerequisites are still essential to be clinically successful. This review highlights the 10 most important aspects of modern adhesive technology based on the "most popular" mistakes in the clinical protocol: Indication, Contamination, Moisture Control, Evaporation, Polymerization, Dentine Sclerosis, MMP Hype, Preparation, Repair and Function. If these 10 points are successfully addressed, the probability of success in the adhesive technique reaches almost 100%.

Traditionally, this therapy is carried out with laboratory-produced restaurations, which usually require preparation of the remaining tooth substance and result in high costs for the patient, so that alternative procedures should be considered. It should be emphasized that any restorative work, even minimally invasive, is only indicated in these patients if the preventive approach of inhibiting further loss of tooth structure is successful at the same time.
Treatment method: The following article presents a case study on the use of direct adhesive composite restorations as a possibility for reconstructing an erosively severely altered dentition. Transfer splints, which are fabricated on the basis of individual wax-up models, are used to reconstruct the occlusal surfaces.
Conclusion: The procedure described is a well-studied and proven method for restoring teeth with erosion-induced tooth wear. As with all new procedures, there will be a certain learning curve for the practicing dentist, after which high-quality restorations can be implemented using this technique.

Many difficulties must be overcome in the course of treatment, including bleeding and tissue management, a flawless adhesive technique, step-free and margin-free application of the restorative material as well as anatomically correct crown shaping and contact area design. Each individual treatment step in the course of the restorative process is crucial for the long-term clinical success of the restoration.
Treatment methods: The R2 restorations divide this complex restorative process into two steps. In the first restorative step, only the deep subgingival portion of the cavity is restored, and the cavity floor is elevated to a paragingival or slightly supragingival level. In the second restorative step, the tooth's crown is reconstructed, and the contact area facing the neighboring tooth is designed. The two restorative steps require the use of various tools and techniques.
Result: The methodical, step-by-step approach makes the entire treatment process more manageable and easier to perform.
Conclusion: Teeth with extensive tooth substance loss as a result of deep subgingival cavities can be restored safely, predictably and with a good prognosis by means of the R2 restorations. Structured follow-up care which focuses on sufficient cleaning of the proximal area is essential for long-term success.

Nevertheless, little is known about his actual contribution to the development of dentistry. This applies all the more to his relationship to National Socialism. Against this background, this article sheds light on Wolf's professional œ uvre, his developments and discoveries and, in particular, on his role in the "Third Reich".
Material and methods: The scientific basis of the study is provided by various archival records and an autobiographical document of Wolf with reference to the year 1945. In addition, a complete evaluation of the available secondary literature on Wolf (biographies, lexical contributions, specialist essays, eulogies and obituaries) was carried out.
Results: Wolf was not only a leading lecturer and dental politician, but also a pioneer of postgraduate education and an inventive developer. However, the majority of his innovations in dentistry were only of passing importance. Contemporaries also emphasised his high level of social competence and his international networking. His role in the "Third Reich" was complex: Wolf joined the NSDAP but was expelled from the party in 1942 because his wife was not "purely Aryan". Nevertheless, he did not suffer a career setback.
Discussion and conclusion: Wolf biography offers a prototypical example of discrepancies between contemporary and retrospective perception: While at the time he was appreciated as a promoter of postgraduate education, as an exemplary academic mentor and as an ingenious developer, today he is remembered primarily as a technically versatile DGZMK president of Austrian origin. Besides his case demonstrates that exclusion from the NSDAP was not necessarily accompanied by professional and social degradation. Rather, the appointment procedures in the field of dentistry show that Wolf was considered for high-profile positions until the end of the "Third Reich".
