D4D Technologies is a high tech medical device company offering state-of-the-art 3D digitizing applications that take the dental profession to a higher level of productivity, patient comfort and convenience with its E4D Dentist CAD/CAM restorative system. This cutting edge technology enables dentists to scan, design and mill a permanent crown for patients in about an hour, without the need for outside lab work and multiple appointments.


The Challenge

Nobody likes to spend any more time than necessary in the dentist’s chair but having to wait days for a crown is cruel punishment. D4D Technologies, based in the Dallas area, provides state of the art 3D dental imaging system that offers dentists and their patients the convenience of creating permanent crown on demand. This innovative system employs lasers, custom optics, 3D rendering, real-time computing and robotics. It is being utilized by dental practices worldwide, including in the US, Canada, Australia, New Zealand, South Africa, and will be launched in Europe.

E4D system consists of three elements. First, a mobile device with an intraoral scanner (IOD) presents the treatment room. The IOD is an included high-speed computer with proprietary software and a 17 LCD. The dentist uses a tool to draw around a crown preparation necessary to create accurate, real-time digital later for optimum fit.

Next, the digital image of the tooth is sent wirelessly and securely to the job server – a desktop computer that computes a tool path from the scanned data. Finally, the tool path data file is transferred to a milling unit that interprets the image and mills the crown.

The critical link is the wireless connection between the IOD and the job server. A dental office typically has a lot of digital “noise” including electronic equipment, physical obstructions and other interference that can hamper the signal and slow or stop communications. Dentists prefer the IOD unit to be wireless so it can easily be moved throughout the office. D4D requires a powerful, yet reliable wireless solution to assure the system runs smoothly and without interference.

The Solution

“You can design a beautiful tooth, but if you can’t get it to the job server the whole process is moot,” said Mark Lazarow, IT manager of D4D Technologies. Mark consulted with Jeff Romick, Vice President of HBR Technologies, a D-Link reseller also in the Dallas area that specializes in security, mobility and healthcare solutions.

D4D Technologies and HBR Technologies partnered with D-Link to perform a rigorous test of their secure wireless products. “We opted for the D-Link® DIR-655 Xtreme N® Gigabit Router with three antennae because it had better reception, data transmission and failure rate. We paired it with the DWA-160 Extreme N Duo adapter,” he said. “Now the system can handle large file sizes in a complex environment that has a lot of transmission noise. Plus it provides complete security and meets HIPPA (patient privacy) requirements.”

Another key component of the D4D imaging system is providing outstanding customer support. It is critical for the company to be able to access its dentist’s computer via the Internet to monitor in real-time and troubleshoot problems. “We needed a router that would maintain a signal and be reliable so we can access our customer’s computers at any time,” Lazarow said.

“The D-Link routers provide us with a more reliable signal and the transmission speeds are three to four times faster than before,” he said, adding that they have deployed more than 700 D-Link router/adapter combos in dental offices worldwide.

“You just can’t mess around when you have a patient in the chair. You have to be efficient,” said Lazarow. “D-Link helps let our dentists do that.”
