02 WORLD NEWS Dental Tribune Nordic Edition | 1/2016 First Nordic facial tissue transplant IMPRINT PUBLISHER: Torsten OEMUS geons and us engineers both see tremendous potential in this kind of collaboration,” said Jani Horelli, CAD/CAM Design Manager at Planmeca. “The field continues to advance at a fast rate and it is very interesting to witness this evolution first hand. I am proud to be part of a highly skilled Finnish communi - ty of specialists. It feels meaningful to take part in improving the lives of people, who have encountered serious illnesses and disabilities.” Planmeca’s collaboration with HUS spans nearly a decade. “Plan- meca’s role has been essential to our work for years—we have been able to utilise computer simula- tions to create saw guides, which allow us to saw at a specific orien - tation and to an exact depth, as well as remove facial structures, which we know match the donor, at a pre- cise angle,” said Törnwall, acknowl- edging the benefits of the com- pany’s 3-D services. By DTI HELSINKI, Finland: Finnish dental manufacturer Planmeca’s Pro- Model technology has supported the first facial tissue transplant procedure in the history of the Nordic countries. The service, which designs and creates patient- specific surgical guides and skull models from CBCT/CT images, helped surgeons to significantly reduce operating time for the demanding procedure, which was performed at Töölö Hospital in the Hospital District of Helsinki and Uusimaa (HUS). In addition to a decrease in surgi- cal time, the ProModel technology was able to produce significantly more precise results compared with conventional methods, the surgical team stated at a press conference. Dr Jyrki Törnwall explained: “Based on literature, we know that it can take 3 to 4 hours to trim bones. In this particular operation, it took Patrik [Lassus] and myself under 10 min- utes to place the transplant. This led to a drastic reduction in the dura- tion of the surgery, while also sig - nificantly improving the accuracy of bone placement.” Both HUS and Planmeca began planning for the operation already years before the surgery was car- ried out and this consisted of mod- elling donor tissue and determin- ing how it matched the recipient, as well as simulating the operation together with the surgeons in ad- vance. Following this, the compo- nents were designed and manufac- tured at Planmeca’s headquarters and transported to the hospital, where they were taken directly to the operating room. The extremely rare procedure, which was only the 35th of its kind in the world, entailed transplanting the patient’s upper and lower jaws, lips and nose, as well as segments of the skin, midfacial and tongue muscles, and the nerves of these muscles. The surgery itself took 21 hours and included a team of 11 surgeons, 20 nurses and other medical experts. The first face trans- plant in the world was carried out in France in 2005.

European Consensus Conference releases update on dental implants By DTI BONN, Germany: The European As - sociation of Dental Implantologists (BDIZ EDI) has released a new consen- sus paper that provides an update on short, angulated and diameter- reduced implants. The guidelines replace the 2011 guidelines, offer rec- ommendations for the assessment of potential indications, and cover advantages and limitations of these types of dental implants. Based on a working paper of the University of Cologne, the consen- sus paper was released after the 11th European Consensus Confer- ence (EuCC), an annual meeting of an expert panel consisting of prac- titioners and academics held under the auspices of the BDIZ EDI, which aims to develop consensus on top- ics in implant dentistry and to draft the respective guidelines. Regarding the classification of short, angulated and diameter- reduced implants, the EuCC agreed upon the following: Implants are usually referred to as short if their intrabony length measures less than or equal to 8 mm and their diameters of 3.75 mm and greater. Ultra-short implants are considered to be those with lengths less than 6 mm. Diameter-reduced implants can be defined as those with in- traosseous diameters smaller than 3.5 mm for placement in sites with reduced alveolar ridge bone width. Implants with diameters less than 2.7 mm are referred to as mini-im- plants. In addition, the EuCC stated that mini-implants have an in- creased risk of loss and short mini- implants should be avoided. According to the EuCC recom- mendations, the use of short, an - gulated or diameter-reduced im- plants in sites with reduced bone volume can be a reliable treatment option, given the risks associated with the use of standard-dimen- sion implants in combination with augmentation procedures. How- ever, the experts highlighted that the implant surgeon and the restorative dentist must have the appropriate training in the use of short and ultra-short implants. BDIZ EDI President Christian Berger said, “It is wrong to assume that short, angulated or diameter-reduced im- plants can be used to resolve one’s own shortcomings in surgical tech- nique. These implants were not de- veloped for operators who have not (yet) mastered the external sinus lift and bone augmentation.” A printed version of the paper is available on request for €2.50 (including VAT, plus postage). The guidelines will also be published in the first 2016 issue of the EDI Journal, the BDIZ EDI’s official member journal. It will therefore be available free of charge to members. ¯ Page 1 “The dentist then finds they are facing a dilemma, to ‘go back’ to the treatment, to optimize quality, or to offer care within the framework of the compensation and, thus, risk accepting an incomplete root fill- ing,” Dahlström explained. Regarding quality, the dentists interviewed reported uncertainty as to what constitutes reasonably acceptable quality. According to Dahlström, they often stated that “good enough” was a more realistic goal than optimal quality. How- ever, despite the difficulties experi- enced, the survey also showed that the dentists wanted to provide good treatment and that they were very concerned about their pa- tients, the researcher said. In order to improve the quality of root fillings, Dahlström sug- gested measures such as in- creased opportunity for contin - uing education, time for discus- sion and exchange of experiences at the workplace, as well as in - vestment in equipment that en- hances treatment, shortens the time needed and improves visi - bility. Approximately 250,000 root fillings are done in Sweden each year and it has been estimated that there are at least 2.5 million root- filled teeth affected by periapical periodontitis. Dahlström defended her thesis, titled “On root-filling quality in general dental practice”, on 4 March. All rights reserved.
