In the world of dental imaging, artefacts have long been a persistent problem, degrading the quality of CBCT images and hindering accurate diagnoses. These artefacts, often invisible to the naked eye, can lead to misinterpretations, complicating the task of clinicians who rely on clear and precise images to make informed decisions. Over the years, many solutions have been proposed, but none have truly resolved the issue—until now.
The Battle Against Artefacts
Artefacts in dental CBCT imaging, particularly those caused by metallic elements like implants or orthodontic brackets, pose a significant challenge. Traditional methods of artefact removal often compromise the integrity of the image, erasing essential details along with the unwanted artefacts. This creates a dilemma: improve image clarity or preserve critical diagnostic information.
Many systems in the market today offer some form of artefact reduction, primarily focused on eliminating soft tissue artefacts. However, they often fall short when it comes to removing artefacts from harder tissues, where precision is most needed. The inability to fully address these issues has left clinicians with images that, while somewhat improved, still don't offer the clarity required for precise diagnosis.
A Revolutionary Step Forward
Enter MEYER's PD-MAR technology, a breakthrough that promises to change the landscape of dental imaging. PD-MAR stands for "Projection Data Metal Artefact Reduction." It refers to a technique used in dental CBCT imaging that specifically targets and reduces metal artefacts. These artefacts can occur when X-rays pass through dense materials like metal implants, causing distortions or "shadows" in the image. PD-MAR works by analysing the projection data (the raw data captured during the X-ray scan) and applying algorithms to remove these distortions, resulting in clearer and more accurate images. This advanced solution not only targets and removes artefacts with unparalleled precision but also retains the vital details necessary for accurate diagnosis. Developed through years of research and refinement, the PD-MAR technology leverages a proprietary TI (True Image) data restoration algorithm to deliver images that are both artefact-free and true to the original anatomy.
Unlike other technologies that tend to "smudge" the image—obliterating artefacts at the cost of losing important structural details—MEYER's PD-MAR provides a solution that meticulously distinguishes between what should be removed and what should be preserved. This means that metallic artefacts, which could previously lead to misdiagnoses, are effectively eliminated without compromising the clarity of the surrounding bone or soft tissue.
Why Artefact Removal Matters
In dental practice, accurate imaging is crucial. Artefacts, especially those caused by metal, can obscure critical details or create false impressions, such as the appearance of caries or bone loss. For instance, when evaluating the success of a dental implant, a clinician might misinterpret the presence of "black shadows" around the implant as a sign of bone resorption or peri-implantitis. However, these shadows are often nothing more than artefacts caused by the way X-rays interact with the dense material of the implant.
PD-MAR technology addresses this issue by restoring the true appearance of the bone and surrounding tissues, ensuring that what the clinician sees is a faithful representation of the patient's anatomy. This not only enhances diagnostic confidence but also improves patient communication. When a patient is shown an image free of misleading artefacts, it becomes easier to explain the situation and gain their trust.
Switching Between Filtered and Raw Data
One of the standout features of MEYER's PD-MAR technology is its versatility. Recognising that some clinicians may still want to see the raw, unfiltered data, MEYER has introduced a simple yet powerful tool in their desktop software: a new button that allows users to toggle the PD-MAR filter on and off. This functionality is critical for those moments when a clinician needs to compare the filtered image with the original data, ensuring that nothing has been lost in the process.
This ability to switch between views provides an extra layer of assurance. By comparing the filtered image against the raw data, clinicians can verify the accuracy of the artefact removal, making it easier to spot any potential issues that might have been obscured or altered. This dual-view approach is particularly beneficial in complex cases, such as post-surgical assessments, where the precision of the imaging directly impacts the treatment plan.
The Practical Application in Clinical Settings
Consider a scenario where a patient has undergone complex root canal treatment. The clinician needs to ensure that the root filling is complete, but high-density artefacts around the filling make this challenging. With MEYER's PD-MAR technology, these artefacts are removed, revealing the true state of the root and surrounding tissues. The clinician can then toggle the filter off to view the original image, providing an additional layer of verification before proceeding with further treatment.
Similarly, in orthodontic cases, where metal brackets often create widespread artefacts that obscure the view of secondary caries or other conditions, the PD-MAR technology can be used to remove these obstructions. The clinician can then review the artefact-free image, toggling back to the original if necessary, to ensure that the diagnosis is based on the most accurate information available.
Setting a New Standard in Dental Imaging
MEYER's commitment to advancing dental imaging technology is clear with the introduction of the PD-MAR filter. By effectively eliminating artefacts while preserving critical details, this technology sets a new standard for the industry. The ability to toggle the filter on and off further enhances its value, offering clinicians the flexibility they need to make confident, accurate diagnoses.
In a field where precision is paramount, the importance of artefact-free imaging cannot be overstated.
MEYER’s PD-MAR technology not only meets this need but does so with a level of sophistication that has been sorely lacking in previous solutions. By providing clinicians with clearer, more reliable images, MEYER is helping to improve patient outcomes, enhance communication, and ultimately, set a new benchmark for excellence in dental care.
