InnerView case study booklet

How Our Patented Technology Performs in Real Cases

The technology behind the InnerView system has been validated in a 10-year, IRB-approved clinical study across 264 test sites, demonstrating over 90% sensitivity in detecting structural damage. But its greatest impact is in everyday use—where it helps clinicians intervene earlier, with greater clarity and confidence.

In this case study, Dr. Cherilyn Sheets used the InnerView® system to evaluate a 90-year-old patient with severe wear. Trendline data revealed progressive micromobility in Tooth 29—despite no symptoms—prompting timely intervention and confirming damage upon preparation.

See how structural risk was identified before symptoms appeared.

This patent family addresses the InnerView® device and system for measurement of structural characteristics of an object, such as anatomical structures (e.g. teeth), physical or industrial structures (e.g. materials and structures in buildings, machines, constructions, etc.) via a reciprocating energy application tool (e.g. tapping rod). The InnerView® device is stabilized during use with a tip which protrudes to contact the surface of the object. The InnerView® device includes a sensor for measuring the contact force between the tip and the object, such as to ensure the proper amount of pressure is being applied by the user. The InnerView® device may also include a membrane or other disposable which separates the energy application tool from the object during use, such as to reduce cross-contamination or the need to clean the device between uses. The membrane or other disposable feature may generally move or deform to accommodate the reciprocation of the energy application tool.

This patent family addresses the InnerView™ device, system and methods for non-destructive measurement of structural characteristics of an object, such as anatomical structures (e.g. teeth), physical or industrial structures (e.g. materials and structures in buildings, machines, constructions, etc.) via a reciprocating energy application tool (e.g. tapping rod). The InnerView® device utilizes a tip which protrudes to contact the surface of the object approximately perpendicularly and is further stabilized and/or positioned consistently through contact of a tab extending from the tip on another surface of the object, such as the top of the object. The shape of the time-percussion response profile is evaluated to make determinations about the structure of the object.

This patent family addresses methods of using the InnerView® system for assessing bone density of a specimen, such as the bone into which an object such as a tooth, dental or other implant is anchored. The InnerView® system utilizes the measurement of reflected energy over a time interval after tapping the object anchored in a bone or other structure with the tapping rod of the InnerView® device or instrument to impart energy to the bone or other structure through the object. The shape of the time-energy profile that is measured by the InnerView® device or instrument may then be evaluated to assess the bone density of the bone or other structure, such as the structural stability of the anchoring or foundation of the object.

This patent family addresses the InnerView® system and a variety of methods for using it for measuring the structural characteristics of different types of specimens, such as honeycomb structures, prosthetic dental implants, teeth and others. The InnerView® system utilizes the measurement of reflected energy over a time interval after tapping the object with the tapping rod of the InnerView® device or instrument to impart energy. The system then evaluates the shape of the time-energy profile to determine characteristics of the specimen, such as the structural stability, acoustic or energy damping capacity. This may be utilized, for example, to evaluate health or stability of the specimen.
