In recent years, a growing number of reports in the literature have linked osteonecrosis of the jaw bones with intravenously administered bisphosphonates prescribed for the treatment of hypercalcemia of malignancy due to bone lesions of multiple myeloma or bone metastases in patients with breast or prostate cancer. Furthermore, an association between chronic oral bisphosphonate use in patients with osteoporosis or Paget's disease, and bone necrosis in the mandible or maxilla has been demonstrated in numerous case reports and case series in the last couple of years. Therapeutically, osteonecrosis of the jaws seems to be difficult to treat surgically, often resulting in a recurring or even progressing lesion. In the present case report of a bisphosphonate-associated osteonecrosis of the maxilla in a patient with osteoporosis, the current literature will be discussed, and open research questions and potential problems for our daily dental practice routine will be addressed.

The importance of constituent units for democratic federations, in general, and of the Swiss cantons for the Swiss Confederation, in particular, is beyond doubt. What is less clear, however, is how to solve conflicting views on the number and type of such units. The Swiss case offers two highly topical examples in this regard: the merger of the two ‘half-cantons’ Basel-City and Basel-Country, on the one hand, and the creation of a new canton encompassing canton Jura and the French-speaking area of canton Berne, on the other. In comparing different sub-national political identities at play in these two cases, the strength of ‘cantonalism’—understood as attachment to and identification with a canton—in Switzerland in the 21st century is shown. Second, different manifestations of cantonalism are compared: centre-periphery in Basel, linguistic vs. religious in Jura. Finally, the similar direct-democratic pathways chosen to solve both conflicting understandings of cantonalism testify to the Swiss commitment to peaceful, negotiated and popularly sanctioned settlements.

Le collage d’un fil torsadé souple sur les faces linguales des six dents antérieures mandibulaires est une modalité de contention couramment utilisée. Les complications sont rares mais peuvent être assez sérieuses pour provoquer des dégâts biologiques. Cet article présente une complication sérieuse d’un fil de contention torsadé souple, collé en lingual. Quatre ans après son traitement orthodontique, un homme de 20 ans a consulté pour la rupture d’un fil de contention torsadé souple. L’examen clinique a montré un torque radiculo-vestibulaire d’environ 35° d’une dent. Une image en tomographie volumique à faisceau conique (Cone-Beam Computed Tomography ou CBCT) a montré que la racine et l’apex de la dent étaient presque totalement hors de l’os du côté vestibulaire. Étonnamment, la vitalité de la dent était préservée. La dent a été ramenée presque jusqu’à sa position initiale; cliniquement, seule une récession gingivale a persisté. Les orthodontistes et les dentistes devraient être conscients des complications possibles des contentions collées. Les patients devraient être clairement informés de la manière dont les problèmes peuvent être détectés à un stade précoce.

The aims of surgical crown lengthening procedures are to improve prosthetic reconstructions at teeth with limited hard tissue, to prevent periodontal problems and/or to improve esthetics. When planning and performing surgical crown lengthening, it is important to consider not only periodontal and technical aspects but also the gingival profile of the neighbouring teeth. This paper presents the systematic approach starting with the diagnosis and indication to the performed treatments and the obtained results and gives clinical recommendations.
