“Nobel Biocare believes the laboratory is upfront and integral to the treatment process,” said Tom Olsen, President and General Manager, Nobel Biocare North America, at the company’s...See more NobelProcera Innovation Forum and Reception on Friday night. “Nobel Biocare’s focus is on three value drivers: designing for life, partnering for life and learning for life.” Joining Olsen on stage were Stefan Holst, DMD, PhD, Global Head of Research and Science, and Peter Wohrle, DMD, MMedSC, a prosthodontist from Newport Beach, CA, who is also a technician. They showcased how the company’s products can help clinicians and labs collaborate more efficiently through an integrated workflow. Among the product highlights: NobelProcera 2G Scanner features a smart motorized holder and dynamic scanning that automatically position each object on the model at the ideal height, tile and rotation to obtain optimal scan data. A new data-transfer capability between the NobelProcera 2G Scanner and NobelClinician Sofware allows CBCT scan data to be merged with model surface scan data. That information can be shared via the NobelConnect network among clinicians and other treatment partners to assist in diagnosing and planning implant surgeries as well as restoration design. Available in zirconia for Nobel Biocare implants with conical connection, the NobelProcera Angulated Screw Channel (ASC) abutment can be designed with an angulated screw channel of up to 25o from the axis of the implant. Using the Omnigrip screwdriver, clinicians can easily grip the screw at any angle within the available range. This combination solves two challenges for clinicians: buccal screw access holes that limit restorative options in the anterior and difficult access in the posterior region from lack of vertical space. The NobelProcera Hybrid fixed-implant bar features new retention elements to better support acrylic and teeth and is ideally suited for the All-on-4® treatment concept. The classic precision-milled zirconia copings from NobelProcera as well as abutments are now available to 3Shape users via the new ‘open access’ program launched last fall.

I recently purchased 2 Jelrus Infinity L30 burn out ovens on E-bay, one used one new. The used performed well for about three months. After three months the display would not ligth up but you could...See more hear the oven heating. After reading all the tech bulletins and manuals the recommendation was to replace the printed circut board. When I priced the board it was 680.00. A little steep. I began by finding a website called Digi-Key.com. They sell electrical components for PCB's. I replaced one part at a time from my good PCB on the new oven and after 4 parts replaced I found the defective part. A crystal/occilator. When I found the exact part on Digi-Key the total cost for the part was .42. I say it so your sure I typed it correctly fourty two cents! If any one needs help with this problem please let me know. I would be glad to help. If you have one of these ovens and don't want it any more also let me know. Thanks, Matt

How long does it take your mill to machine a (insert restoration type here)? This seems to be an area that the digital dental labs and milling centers are most concerned with and can likely be a...See more key criterion in their purchase of a milling machine. Of course machine cycle time is important but it is in reality, not a true gage of a milling machines production and effect on overall throughput and profitability. While the VersaMILL is capable of producing single unit zirconia restoration in as little as 6 minutes and titanium implant abutments in less than 20 minutes, our answer to this questions is typically: “How long do you want it to take”? This may, on the surface, appear to be a flippant answer but in reality we are quite serious. Often time sacrifices are made and indeed even tolerated in the pursuit of fast cycle times. Sacrifices that include: Decreased Cutting Tool Life Increased Manual Bench time Decreased Accuracy Inferior Surface Finish (i.e. Occlusal Surfaces) Poor Feature Definition (i.e. Margin Definition) Increased Design Time Does it make sense to be able to pull a restoration off of the milling machine in 4 minutes only to spend another 10 minutes on the bench to clean it up OR determine it is unacceptable thereby having to re-make it OR spend additional time designing the restoration to avoid machine issues OR spend additional money on expensive diamond tooling due to improper feed/speed rates, OR to sacrifice finish or detail, etc.? The achievement of high quality, in terms of work-piece dimensional accuracy, surface finish, production rate, wear on the cutting tools and economy of machining in terms of cost saving are the main challenges of modern dental manufacturing. Machine stability in terms of vibration dampening characteristics of the axes and spindle drive systems, spindle run-out, machine positional accuracy, cutting tool materials and geometry, machining parameters such as speed, feed, depth of cut and CAM programming strategies all play a factor in enabling you to reach your throughput and profitability objectives. We at Axsys not only have the PRODUCTS, we even more importantly, have the KNOWLEDGE and EXPERIENCE to maximize their effectiveness in pursuit of your goals and objectives. With our products we can provide you with the throughput you need to be competeitve while enabling you to ship superior product to your customers while yeilding high, predictable profits. You may even find that with the VersaMILL and our expertise, an extremely quick return on investment can be realized in zirconia restoration alone; thanks to the tooling cost savings associated with our extremely long tool life (in many cases over 200 units per tool) from tooling that costs a fraction of what competitive solutions offer. Contact Us today to learn more about the Axsys Advantage so we can put our experience to work for you.

There are many interrelated factors that affect a DMC’s (Dental Milling Center) reliability, speed and accuracy, the three most important of which include the spindle drive system, machine control...See more system and axis drive system. The spindle drive system provides power to the cutting tool to remove material. The control (or machine operating system) is the brain of the DMC and coordinates machine motion. The axis drive system determines how smooth the motion of the DMC is and how it translate into parts that are consistently accurate with the required surface finish quality. SPINDLE DRIVE The amount of force and wear and tear that a DMC’s spindle must endure means the design of the spindle and the quality of the parts buried within the spindle is vital to the DMC’s spindle’s performance and its lifespan. Quality components not only determine longevity of the spindle, they determine how the spindle handles speed, torque and vibration. Key considerations include; style (belt or integral motor), bearings (type, lubrication and cooling), motor, shaft and housing Our VersaMILL addresses these considerations by utilizing a rigid, high quality and reliable precision spindle system that is also economical. The VersaMILL's high speed air cooled spindle can operate at high rpm while producing minimal run-out at the cutting tool edge allowing for long tool life and outstanding surface finishes; without the need for expensive tooling systems such as shrink-fit, polygonal clamping, micro collets and others. AXIS DRIVEThe quality of the axis drive system is also a function of the construction of the frame and the axes way system. This is the key area in the construction of a machine tool as it determines rigidity, vibration damping capacity, and resistance to side thrust. It's the balance between these three critical areas (power, speed, accuracy) that you must evaluate against your current and future needs to get the best buy for your money. Additionally the type of axis drive motor (servo or stepper) and motor control system (open-loop or closed-loop) is important to assure positional accuracy, repeatability, smoothness of motion, vibration, tool wear, quality of surface finish and quietness of operation. The VersaMILL’s closed-loop servo motor system is the system of choice in a quality DMC as it avoids the positional/repeatability accuracy, noise and maintenance issues associated with open-loop systems that rely on stepper motors to drive the machine axes. Most dental milling systems available today lack the rigidity of construction and fixturing, quality components, speed, versatility and size to effectively produce the various restoration types from the soft and hard materials that are required of them to maintain or grow their business. The VersaMILL 5X eliminates these issues by providing a single, cost-effective, compact and easy-to-use open platform high precision dental milling machine constructed from heavy duty, reliable components utilized in heavy idustrial applications that can be implemented in any lab environment. Take a look at the VersaMILL 5X for your next purchase of a dental machining center; it may well be the only machine you will ever need.
