Up close examination using ultrasound

In recent years computer-aided methods of planning and producing dental prostheses have rapidly gained in importance. High resolution impressions of treatment areas are essential for ensuring a well-fitting prosthetic. With conventional impression-taking techniques, results are often impaired by gums, blood and saliva which affect the cast quality.

 

With our high-resolution ultrasound intraoral scanner, we are providing a solution to this problem.

Process

01

Highly-dynamic
hybrid kinematics

The intraoral scan is achieved cost-effectively using a specially adapted high-frequency ultrasonic transducer and highly-dynamic, fine-tuned multi-axis kinematics. The scanner technology and algorithms have been optimally combined for perfect impressions with reduced treatment times.

02

Model-based
signal analysis

The demand for improved spatial resolution and scanning accuracy has made it necessary to develop new approaches to signal processing, scan strategies and data reconstruction.  Model-based concepts combined with powerful and intelligent algorithms make it possible to scan subgingival structures such as preparation margins and bone. 

03

Fit accuracy

It has been shown that crown fittings planned and produced on the basis of ultrasound data have a comparable fit accuracy to those created using the optical manufacturing chain. Accurate impressions of subgingival areas were successfully taken without the need for prior exposure and drying.

04

CAD / CAM Integration

The ultrasound micro scanner can be fully-integrated into the process chain of modern dental manufacturing technologies. After impressions have been taken, surface models of the various tissue layers are available in standard open formats (e.g. stl). Ultrasound data is suitable for planning and producing high-quality prosthetics and offer numerous applications within implantology and prosthetics.
