The Minamata Convention on Mercury is the first new global Convention on environment and health adopted for close to a decade. It is named after the place where thousands of people were poisoned by mercury-tainted industrial wastewater in the mid-20th century in Japan, leading to crippling symptoms that became known as the Minamata disease. Mercury is a highly toxic heavy metal which poses a global threat to human health and the environment. After the official recognition by Japanese government in the health catastrophe caused by mercury that lasted 36 years, it started in 2003 a cooperative program with United Nation to control mercury globally, to save human and environment through hard efforts that had been presented by many countries, research centers and scientific institutions.

This article describes a treatment concept for fabricating implant-borne single restorations efficiently. Industrially prefabricated blanks which include integral interfaces with a titanium/adhesive base form the basis for CAD/CAM fabrication of the implant superstructure. The author describes possible indications and the clinical procedure.

Direct composite restorations in the posterior region are standard measures in the treatment spectrum of modern conservative/restorative dentistry. Due to the considerable growth in aesthetic awareness over the past two decades, nowadays the majority of patients are no longer prepared to accept metallic restorations and request tooth-coloured alternatives. Apart from ceramic inlays, direct composite restorations also provide patients with a permanent option. This type of filling is very popular with both patients and operators and, in the meantime, many clinical studies have proven its ability to bear masticatory loads in the posterior region. Apart from the composites with conventional methacrylate chemistry, the range of plastic filling materials has now been extended by a purely nanohybrid Ormocer version which is free of classic monomers.

After many years of cautiousness in Germany, apart from xenogeneic and alloplastic bone augmentation, allogenic augmentation materials are increasingly being used for reconstructing jaw defects. This article reviews the different types of allogenic bones and their individual risk potential. In addition, the clinical results for mineralised processed allografts are summarized and new techniques outlined which produce very promising results and which, to date, were only employed with autogenous bone.

Dental implantology is a growing area in modern dentistry. The use of dental implants has greatly expanded the range of treatment options after tooth loss. With the extended use of dental implants, however, the associated complications have become more widespread. Peri-implant infections are an increasingly important problem. Their causes and the antiseptics used most commonly in peri-implantitis therapy are described in this article.

Exceptionally comprehensive documentation is used to present a case where monolithic lithium disilicate restorations were fabricated for both the anterior and posterior regions. Although fully anatomical fabrication was selected for both indications, they were fabricated using different techniques. Part 1 of this article focusses on diagnosis, planning and the manually fabricated anterior restorations (pressing procedure, IPS e.max Press Multi).
