Ultra Low Dose™ protocol
Planmeca ProMax® 3D family units offer an Ultra Low Dose™ imaging protocol, where effective patient dose in CBCT image is even less than in a standard 2D panoramic image. The Planmeca ProMax® 3D is designed to obtain complete information on the patient’s anatomy in the minutest detail. This intelligent and multipurpose X-ray unit provides digital panoramic, cephalometric, and 3D imaging as well as 3D photos and 3D model scans.
Ultra Low Dose imaging is based on intelligent 3D algorithms developed by Planmeca.
Ultra Low Dose images are used, for example, in the following procedures:
- Localization of unerupted and impacted teeth prior orthodontic treatment
- Defining orthodontic landmarks for cephalometric analysis
- Postoperative and follow-up images in maxillofacial surgery
- Airways studies
- Sinus studies
- Implant planning
The system always allows the clinician to choose the optimal balance based on the ALARA (As Low As Reasonably Achievable) principle.
Planmeca’s new Ultra Low Dose™ imaging protocol has changed the imaging practices at Tampere University Hospital in Finland. Dr Jorma Järnstedt, DDS, in Tampere University Hospital’s Oral and Maxillofacial Unit discussed his experience with the ProMax 3D.
“We have been using the new Ultra Low Dose mode since last summer and have found it to be very useful in many imaging indications. These include postoperative follow-up, orthodontic cases requiring localization of uninterrupted teeth and their effects on the neighboring ones, sinus imaging in certain ENT cases where sinusitis needs to be excluded, pharyngeal airway measurements on sleep apnea patients, as well as all implant cases.
“The new imaging mode has already changed the traditional imaging protocol: In many cases, 2D imaging can no longer be justified, since an Ultra Low Dose 3D image simply gives so much additional information with a similar radiation dose. Our patients are often concerned about radiation exposure, but once they hear that the dose is even lower than in traditional panoramic 2D imaging, they are always really relieved. Also, our surgeons often specifically ask us to use the Ultra Low Dose protocol.
“We take around 2,000 CBCT images per year at the Oral and Maxillofacial Unit, and the number is constantly growing. We have been using the new Ultra Low Dose protocol for the imaging of both larger and smaller areas. It has proven to be a very beneficial method giving a vast amount of detailed anatomical information at a low radiation dose.”
