Dentistry NewTom 900 capabilities upgraded

Three years ago, on May 10, 2001, a ribbon-cutting ceremony was held at the School of Dentistry for the NewTom 9000, the first dentomaxillofacial dedicated Cone- Beam CT in the United States.

The School’s NewTom volumetric digital radiograph machine was featured in local press and was lauded for its revolutionary ability to capture detailed images (360 slides) of the bony tissue of the skull, jaw, and teeth during a 70-second scan, with 80 percent less radiation than delivered by a traditional CT scan.

In July, the School installed the first upgrade to the NewTom 9000. LLU was the first university in the United States, and the first site on the west coast to receive the New-Tom 3G upgrade. The new software:

  • increased the resolution three times (from 8-bit to 12-bit resolution);

  • increased the scannable area from 9-inch volume to 12-inch volume;

  • shows soft tissue;

  • has one-quarter less radiation than the NewTom 9000 system;

  • has a 36-second scan time compared to a 70-second time required by the NewTom 9000;

  • is more user-friendly.

Until now, scans captured an area from a patient’s chin to midway up the sinuses.

“The increased scannable area,” says Damon Needelman, IT project manager for the department of orthodontics, “has made it possible for the scan to show the area of concentration the doctor wishes to study, from the bottom of a patient’s chin to mid-forehead.”

Viewing the scan from any angle, the NewTom 3G is able to show soft tissue. “This will give the doctors even more information, empowering them to make easier diagnoses,” reports Mr. Needelman.

The new technology will enhance treatments from root canals to complex oral surgeries, implant, and periodontal studies.

To prepare for increased storage demands, the School of Dentistry has purchased new servers and increased the network to gigabit capacity.

The departments of implant dentistry, periodontics, and oral surgery purchased their own software licenses.

According to Mr. Needelman, there is backwards compatibility for scans taken prior to the upgrade with minimal effort.

The orthodontic department is looking forward to providing radiological services to non-School of Dentistry referred patients. For information please call the orthodontic department’s volumetric imaging laboratory, (909) 558-7425.
