Ultrasonography in Periodontology

Technology Roadmap Sections and Deliverables

Roadmap Overview

Ultrasonography in dentistry is a novel approach to diagnosing inflammation, specifically periodontal tissues (hard and soft tissue) and disease. An accurate dental diagnosis requires imaging and clinical evaluation. This technology is a level 3 technology with the unique identifier “3US - Ultrasound”. While this may not replace other types of medical imaging needed for an accurate dental diagnosis, it is a non-invasive technology that can be used for patient monitoring as well and enhances diagnostic capabilities. Early studies demonstrate uses in wound healing and tissue maturation. Other technologies that would be at level 3 are radiographs, intraoral scanners, and cone beam computed tomography. This technology can be further broken down into six level 4 identifiers: 4TD, 4CPU, 4PW, 4SC, 4CT, and 4EN (see DSM Allocation for descriptions of identifiers).

Indication: Dental disease is typically diagnosed through clinical and radiographic evaluation. Not only does this leave a patient exposed to radiation, but this model is reactive rather than preventive. The use of ultrasound in dentistry as an imaging modality is novel. Currently, it is used for wound healing research but we propose developing a POC model with appropriate resolution that could be used at several check ups throughout the year to track inflammatory biomarkers. This noninvasive technology could be beneficial in preventing disease.

Technology: Electricity is sent to the transducer which has piezoelectric crystals. Piezoelectric crystals convert the electrical signal into a sound wave. The soundwave then travels through a gel medium into a patient’s tissue. The sound waves then bounce back into the transducer and the signal is then generated and processed by the computer processing unit (CPU). Once it has been processed, it is sent to the graphic processing unit and displayed on a screen for the user to interpret.

Position of Company vs. Competition

The field of ultrasonic imagery in dentistry, particularly in periodontology, is an emerging market with no established players. This presents a unique opportunity for our company to pioneer and lead in this niche. However, to understand our competitive positioning more broadly, we may examine the current landscape of ultrasonic technology in general. The ultrasonic technology market is robust and diverse, with several key players dominating various segments. Major companies such as GE Healthcare, Philips, Siemens Healthineers, and Canon Medical are leading the charge in medical ultrasonography. These companies have developed advanced ultrasound devices used in multiple medical fields, including cardiology, radiology, and obstetrics.

Key competitors include:

- GE Healthcare - Philips - Siemens Healthinneers - Canon Medical - VEVO

Technical Model

Description of Tradespace

The tradespace for ultrasound imaging in dentistry centers around key decision variables that impact imaging performance in dental applications. Some of the selected devices to study include the Vevo 3100 with MX250 transducer, Vevo LAZR-X, and Vevo 3100 with MX550D transducer. Critical parameters include frequency range (ranging from 8 to 23 MHz), aperture area (0.7 cm²), and transducer depth (up to 10 mm), which directly affect spatial resolution (approximately 30 micrometers) and frame rates (up to 200 Hz). This array of options informs the optimal balance of imaging quality, device size, and operational cost for dental ultrasonography.
