“During our 13-year history, 3Shape has had a strong and continuous focus on R&D. In fact, 40% of our staff members are involved in R&D. It’s our calling, our DNA,” said Flemming...See more Thorup, President and CEO of 3Shape during his opening remarks at the company’s press conference in Chicago. One of the latest developments is the D900L scanner featuring a larger interior for scanning fully articulated models and large impression trays. The company also launched the Dental System™ 2014 which is available to all 3Shape Dental System™ subscribers as part of their LABcare™ package. Among the new features: Optimized CAD Design Workflow and a redesigned interface that offers greater user-friendliness. For instance, the redesigned workflow-progress bar guides you through each scanning step; it’s now easier to move back and forth between different workflow steps and to rescan individual dies if needed. 3Shape Implant Studio™ brings together implant planning, prosthetics and drill guide design, enabling labs to provide complete treatment packages up front. In addition, the software can align CT and TRIOS scan data, providing a panoramic preview and enabling the user to place a virtual crown as guidance for optimal positioning of the implant. A Splint Module optimized for fast and easy design of splints, nightguards and protectors. Auto-crown functionality allows the design of full anatomical crowns. Improved RealView Engine™ offers close to photo-realistic teeth texture; designs look even more realistic when superimposing an image of the patient’s face in the design process. CAD Block integration allows you to virtually position multiple anatomy designs in one or more blocks before milling, maximizing material usage. TRIOS Upgraded“Dental System 2014 also features optimized workflow for working with TRIOS scans and other digital impressions,” said Tais Clausen, Co-Founder and CTO, during his live demonstration of the TRIOS Digital Impression System. Introduced two years ago, the system is on a successful growth track, with the number of TRIOS cases increasing 5% per week. The upgraded TRIOS system now has an integrated shade measurement functionality that captures and embeds the shade information (VITA Classic and Master shades) as the dentist takes the scan. “This function greatly enhances shade communication between the dentist and laboratory; it’s a game changer,” said Rune Fisker, VP Product Strategy. The system now takes HD photos and the color of the RealColor™ scans has been enhanced. “The HD mode offers incredible resolution and combined with the color technology, it’s easier for the dentist to set the margin line and evaluate the clinical situation,” explained Clausen. The TRIOS also features a slimmer cart with a Multi-Touch screen that lets the dentist zoom, move and spin the images much like a smartphone. The new Resnap function permits the user to start and stop scanning and it will automatically pick up where the scanner left off. Also, a new iPad app enables the dental team to share 3D scans and designs, photos and comments about cases; it’s available on iTunes.

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.

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.

For the last three years, I've been involved in titanium research and development with Precision Milling Center in West Valley City, UT, and read with interest Luke Kahng's recent article on titanium (How...See more to Fabricate an Esthetic Porcelain to Titanium Restoration, LMT November/December 2011, Click here to Read). The piece is well written and supported with excellent photography. However, I'd like to add some technique recommendations that are critical to the success of processing porcelain-fused-to-titanium restorations: When designing the framework, follow your manufacturer's instructions regarding minimal thickness, usually .4mm for anteriors and .6mm for posteriors. Metal preparations should always be done with SHP burs designed just for titanium. As Khang says, always cut in one direction and also use a maximum speed of 15,000rpm. Never use more than 2-2.5 bars or 30-35 psi of pressure when sandblasting titanium. Also, sandblast at a 45o angle and never use a particle size less than 120-150 microns of pure aluminum oxide abrasive. The article instructs you to blast the inside of the frame but first blast the outer surface prior to porcelain application; the inner surface of the abutments will be sandblasted after firing cycles to remove the oxide that forms internally. To clean the inside of the abutments, use a 50-micron-grit abrasive and blast at 2 bars or less of pressure; a larger grit size can damage the margins. After sandblasting, bench set the titanium frame for 5-10 minutes (not to exceed 30 minutes) to undergo the passivation process. This step is critical to the success of bonding to titanium; during this time, titanium naturally develops a very fine oxide layer that prevents corrosion and is the contributing factor for biocompatibility of the material. Failure to implement this step will lead to failure of the restoration. Avoid ultrasonic cleaning after sandblasting; steam cleaning is recommended by most manufacturers. GC recommends that its GC Initial Porcelain Ti™ Bonder be applied in a thin enough layer that the coping shines through. When applying the bonder, brush out pooling and thick streaks of the bonder for a thin, uniform coating. Properly fired bonder surfaceis dark and has a slightly shiny appearance; gray patches of fired bonder indicate the use of too much bonder. GC also recommends that the first layer of opaque is applied as a very thin wash on the Ti Bonder treated surface; apply additional layers as needed along with appropriate modifiers. Complete the porcelain buildup, finish contours, set occlusion and glaze. When polishing and cleaning titanium after the glaze, use polish wheels and high-shine compounds specifically designed for titanium. Polish the exposed titanium finish lines, wait 10 minutes for the passivation process to occur, then steam clean the restoration. This passivation process seals the surface of the titanium and prevents corrosion that would discolor the metal later.
