DITZINGEN, Germany: At this year’s International Dental Show, high-technology company TRUMPF unveiled a new processing solution that makes the production of customised implant-supported dental prostheses more efficient. The new process focuses on the manufacturing of dental abutments and can be retrofitted to the current series of TRUMPF TruPrint 1000 3D printers.
The TruPrint 1000, which is specially designed for the dental industry, can print up to 64 implant abutments in a single print job. Thanks to the use of preforms, which are special bases or substrates with a prefabricated implant connection geometry and a flat platform on which an individual component can be printed, it completes the whole process in less than 3 hours.
Abutment manufacturing has traditionally relied on milling, bonded hybrid abutments or complex casting methods. However, the new TRUMPF preform solution makes the fabrication process more efficient while using fewer materials.
“Implant-supported dental prostheses are the world’s fastest-growing dental industry segment,” said Reinhard Sroka, dental industry manager at TRUMPF. “That’s why dental laboratories need to act fast to tap into this lucrative and pioneering field. Harnessing the power of high-productivity 3D printers is the best way to tackle growing cost and competitive pressures,” he added.
TRUMPF has also developed a special adaptor plate for its preform processing solution that can be loaded with preforms before printing and inserted into the TruPrint 1000, where it is calibrated fully automatically. The printer, which comes with one or two lasers, uses the laser metal fusion technique to melt the metal powder layer by layer and to fabricate individual abutments in the powder bed.
A versatile choice for implant prostheses
Besides boosting productivity, additive manufacturing offers major benefits when it comes to complex abutment geometries. Users have almost unlimited freedom to choose where to position the screw channels, and even the most complex structures can be fabricated with ease.
The new TRUMPF preform processing solution adds an extra dimension to the TruPrint 1000, making it the perfect all-in-one machine for implant prostheses manufacturing. What is more, the multiplate option enables the system to produce parts without manual intervention on up to four build platforms, paving the way for overnight and weekend work. The system automatically switches to the next platform after each production job and stores the abutments directly within the machine. However, the multiplate function cannot currently be used in tandem with the new preform processing solution.
