The presence of sufficient bone volume is one of the most important criteria for successful osseointegration of implants,1 wherefore restoration of atrophied edentulous maxillae poses a great dilemma for the surgeon and restorative dentist. Sinus bone grafting to build new bone for implant anchorage in atrophied jaws entails multiple surgical interventions and has varying implant success rates, high potential for donor site morbidity and increased surgical costs.2, 3 A major breakthrough came when Brånemark first used custom-designed, longer implants inserted into the zygomatic bone in support of a craniofacial prosthesis in the 1980s.4 When used in the treatment of maxillary atrophy,5, 6 zygomatic implants present a graftless alternative.

When I first heard about clear aligners in the early 2000s (the US Food and Drug Administration approved the use of clear aligners to straighten teeth in 1980), it must have sounded like science fiction. The fact that it was created in Silicon Valley by people who had nothing to do with the dental industry, in seeking solutions that do not require complicated appliances in the mouth, is really an incredible story.

Kuraray Noritake Dental’s KATANA Zirconia ML was the first zirconia on the dental market with integrated shade gradation. First presented at the International Dental Show in 2013, this material has revolutionised the world of zirconia. Over the course of time, KATANA Zirconia UTML and STML and the change from ML to HTML have created a complete product portfolio. This article highlights the different characteristics of each of these varieties.

A female patient came to Studio Cortellini in Riccione in Italy in order to improve not just her ability to chew but also the overall aesthetic appearance of her teeth. A clinical examination revealed the presence of several erosive lesions that contributed to her chewing problems and had caused a decrease in enamel thickness. This reduction in enamel, combined with a number of discoloured composite restorations, negatively affected the aesthetics of her smile.

What do dentists want to know about occlusion? Occlusion may appear complicated because of the multiple factors involved, such as teeth, muscles and the temporomandibular joints (TMJs). It can also be confusing, owing to imprecise terminology and philosophies of occlusion.

The lasting success of any root canal therapy is always only apparent after long-term observation. In this article, based on a case study, the author demonstrates how a strongly curved canal in the posterior maxilla was prepared using pre-bendable nickel-titanium (NiTi) files, ensuring that a bacteria-proof seal is created that can last for as long as six years after the procedure. Here, the use of a reduced file sequence is just as important as the advantages of a flowable obturation material.

In our clinical practices, dentine hypersensitivity (DH) has always been a challenge. Our best approach was to suggest at-home solutions such as sensitivity toothpaste or mouthrinse, but often there was no significant relief experienced by our patients. Last year, we met Richard Whatley, CEO of BioMin Technologies, who gave us some samples of BioMin F toothpaste for provision of relief from DH, and he explained the technology behind the effectiveness of this novel bioactive glass-based toothpaste. The bioglass particles contained in BioMin F toothpaste adhere to dental hard tissue and then slowly dissolve in saliva to release calcium, phosphate and fluoride ions, which precipitate on nucleation sites as fluorapatite crystals to occlude open dentinal tubules.

A 76-year-old female patient visited our clinic owing to pain in the left maxilla. She had a fistula in the buccal gingiva between tooth #25 and position #24. There were implants in positions #24 and 23. Tooth #25 already had a crown. The tooth had been affected by secondary caries earlier and had been repaired. A periapical radiograph showed an active inflammatory process in progress from the endodontically treated tooth that greatly worsened the prognosis and could have adversely affected the implants. The prognosis was therefore considered poor and we decided to extract the tooth.
