VITA YZ SOLUTIONS: ZIRCONIA FOR EVERY INDICATION Discover the universal material system in four degrees of translucency VITA YZ SOLUTIONS is a com- plete zirconia material range in four degrees of translucency for every in- dication with the perfect match to the accompanying VITA veneering, colouring, staining and cementation systems. The base for reliable shade reproduction and highly aesthetic re- sults is the tooth-shaded pre-coloured (multi)colour blanks matching per- fectly to the VITA shade systems. Alternatively, unstained white material versions can be infi ltrated individually with VITA YZ SHADE LIQUIDS. For effi cient and safe CAD/ CAM workfl ows, the premium zirco- nia VITA YZ SOLUTIONS provides edge stability, homogeneous micro- structures and tested sintering prop- erties for accurate and precisely fi t- ting restorations. Super- and extra-translucent Now VITA YZ SOLUTIONS offers the super-translucent VITA YZ ST and the extra-translucent VITA YZ XT materials, in addition to the translucent and highly translucent blanks. The pre-coloured blanks of- fer a perfect shade match to the VITA classical A1–D4 shade guide and are PLANMECA CALM FOR PATIENT MOVEMENT CORRECTION IS “THE REAL DEAL” The new Planmeca CALM algo- rithm for correcting patient move- ment in CBCT images is taking den- tistry by storm, according to the Finnish company. As the fi rst end- user solution for movement artefact correction from a dental manufac- turer, the feature has already been praised by dental professionals out in the fi eld. In an interview about Planmeca CALM, the company’s 3-D imaging specialist Mikko Lilja spoke about how the innovative algorithm came to be and why he believes every dentist can benefi t from it. “It all happened very naturally,” said Lilja in describing the back- ground to developing Planmeca CALM, the trail-blazing iterative al- gorithm for correcting patient move- ment. “I had gained a good under- standing of movement as an imaging problem in my doctoral research work. When it then turned out this was also a topic of interest for Planmeca, it all came together.” The name “CALM” stands for “Correction Algorithm for Latent Movement” and describes a projec- tion geometry optimisation algo- rithm that can analyse and compen- sate for patient movement in CBCT images. The outcome is an improved image that eliminates the need for re- takes—saving time and improving pa- tient safety. Patient movement is among the most signifi cant chal- lenges to CBCT image quality. When a patient moves during imaging, it produces artefacts that affect the quality of the image. “In tomographic reconstruction, the assumption is that the measure- ments—in this case, the CBCT X-ray projection images—are geometrically consistent with one another,” Lilja explained, “but when a patient moves, the data no longer adds up, which shows in the reconstruction. What Planmeca CALM does is it re- stores the consistency of the X-ray measurements by tracking the move- ment of the patient, resulting in a sharper fi nal image.” Planmeca CALM works with all volume and voxel sizes and adds only under 30 seconds to the overall re construction time. The feature can be applied after the scan is complete, but also before exposure to ensure that the volumes are already cor- rected when they are accessed in the Planmeca Romexis software. “In the past, dentists would send their unsatisfactory images to the manufacturer for reconstruction or just redo the entire scan, but with Planmeca CALM this is now a thing of the past. We are proud to be the fi rst dental manufacturer to provide a solution for movement artefact cor- rection to the end user,” Lilja stated. According to Lilja, an end-user solution for patient movement cor- rection had been on Planmeca’s algo- rithm development road map for some time and was assigned to him upon joining the Planmeca 3-D imag- ing team. “I think the timing was perfect for everybody. With Planmeca’s ex- pertise in medical imaging and image reconstruction and my knowledge of movement correction, we just imme- diately put our heads together and got to work,” he said. The develop- ment process was not without its challenges, and a great deal of effort went into creating a dedicated algo- rithm for Planmeca CBCT devices. “My previous experience was re- lated to industrial tomography imag- ing, where things like reconstruction times and the imaged target itself were very different. So, although our fi rst prototype tests were encourag- ing, we had to go back to the drawing board time and again to produce a new algorithm for dental imaging. Thankfully, I had a lot of help from my extremely capable colleagues, which allowed me to focus on the core problem,” Lilja continued. The fi nal product was presented at the 2017 International Dental Show in Cologne in Germany amid much excitement and industry an- ticipation, as Planmeca CALM offers many advantages for dental imaging. The feature is particularly benefi cial when imaging restless or livelier patients, such as children, individuals with special needs or elderly patients. Ac- cording to Lilja, how- ever, the algorithm can add value to any image. “On the one end, we have, of course, the images where the patient has moved to such an extent that an image may be unusable without Planmeca CALM, but in my experience, it always improves the quality of the image. Even in cases where you might not typically think there has been signif- icant movement, Planmeca CALM can noticeably enhance the image and enable seeing more details,” Lilja described. Mikko Lilja “Whatever the case, it is being able to correct movement artefacts ‘in-house’ rather than having to re- sort to retakes or sending the image for enhancement which is key here,” he went on. “When dentists are able to make the correction themselves, the end result is improved diagnos- tics, time saved, reduced costs, and less exposure to radiation.” Planmeca CALM has been praised by dentists since its release FKG DENTAIRE PRESENTS ITS SINGLE-FILE XP-ENDO SHAPER PLUS SEQUENCE business available in monochromatic and polychromatic versions. VITA YZ ST is the ideal material for monolithic and partially veneered posterior tooth restorations. VITA YZ XT al- lows the production of monolithic and partially veneered anterior tooth restorations in the aesthetic zone. With the four degrees of trans- lucency of VITA YZ SOLUTIONS, practitioners can now benefi t from a full range of resto rative possibilities for every clinical situation.

It has been truly heart-warm- ing to hear that the hard work that went into it is also bearing fruit. I’ve even heard that the software has been tested by shaking a phantom head around in the X-ray unit, and that all tests have come to the con- clusion that it’s ‘the real deal’. It’s a great feeling,” Lilja summed up. Plandent AB, Sweden www.plandent.com Booth B08:28, 31, 32 A new generation of instruments launched by leading Swiss endodon- tic company FKG Dentaire enables safer and more effective root canal therapy owing to their unique 3-D extension capabilities. The XP-endo Shaper Plus sequence solves a com- mon problem for dentists: how to treat complex root canal systems without causing damage to the dentinal structure. Combining adaptive core technology with 3-D de- sign, FKG has created instruments that can easily adapt to the canal anatomy to clean areas once impos- sible to reach. The result is enhanced debris removal and irrigation for a 10 Swedental 2018 more gentle, conservative treatment compared with instrumentation us- ing conventional NiTi fi les. FKG’s patented MaxWire alloy from which the fi les are made re- acts to the body’s temperature, making the tools highly fl exible compared with instruments of the same fi nal size. A small, free-fl oating adaptive core designed in 3-D allows the instruments to expand and pro- gress with agility along the canal while resisting cyclic fatigue. The XP-endo Shaper performs 3-D debridement of the canal while respecting its natural shape, and the XP-endo Finisher achieves 3-D clean- ing and biofi lm removal, including in areas impossible to reach with con- ventional fi les. The instruments are delivered in a sterile blister pack de- signed for single-patient use, thus maximising safety. According to the company, with the XP-endo Shaper Plus sequence, dentists have the most advanced Swiss precision tools at their fi nger- tips to perform complete, minimally invasive root canal instrumenta- tion.
