57 ortho 1 2016 digital imaging Planmeca ProMax 3D units—Ideal for imaging patients with braces pain during the first days after the wire change or adjustment, as well as change of aligner. Leading research institutions such as The Forsyth Institute, Cambridge, USA, and Kyung Hee Univer- sity, Seoul, Korea are now examining the effects of PBM. Research by Chiari et al at Boston University, studied the effect of PBM-induced tooth move- ment using extraoral transcutaneous photother- apy on the rat periodontium. The results showed a 2.8–3.7 x faster tooth movement. Clinical research on the effect of PBM during ortho­ dontic treatments provided astonishing results.

Biolux Research Ltd. 220-825 Powell St. Vancouver, BC, V6A 1H7 Canada www.bioluxresearch.com Planmeca ProMax 3D is a CBCT product family consisting of exceptional all-in-one imaging units. The intelligent units support several different imag- ingmodalitiesandprovideallneededspecialisttools. As a reflection of their suitability for orthodontics, three of the Planmeca ProMax 3D units—Classic, Mid and Max—have now been certified for use withthesuresmiletreatmentmanagementsystem. Planmeca ProMax 3D units have been designed to meet the strictest of requirements in maxillofacial imaging. They support three different types of 3-D ­imaging(CBCT,3-Dfacephotoand3-Dmodelscan), andalsoextraoralbitewing,cephalometricanddigi- tal panoramic imaging.

The CBCT units’ stable support system helps pa- tients remain completely still during imaging. This is especially important when acquiring high con- trast images as part of orthodontic treatments. Certified for use with suresmile The Planmeca ProMax 3D Classic, Mid, and Max CBCT units are now certified for use with the sure- smile treatment management system by OraMetrix. Thesuresmilesystemhasbeendesignedtoenable orthodontists to ­visualise and simulate multiple di- agnosticset-upsanddesigncustomisedarchwires for every patient. The accuracy of patient scans plays a critical role in maximising the effectiveness of the suresmile system. Combining the system with a CBCT unit allows the efficient visualisation and virtual ma- nipulation of teeth and their roots. The orthodontic braces protocol of Planmeca ProMax 3D units has been optimised for use with the suresmile treat- ment management system. See more at a lower dose TheeffectivepatientdoseofCBCTimagingisclose­ly related to the protocol used for scanning. Planmeca has established itself as the industry leader in pio- neering ultra low dose imaging. The innovative Plan- meca Ultra Low Dose protocol available in all Plan- meca ­ ProMax 3D X-ray units reduces the effective patientdoseinCBCTimagingsignificantly—without a statistical reduction in diagnostic image quality. At best, this means lowering patient doses to levels beloweventhatoftraditional2-Dpanoramicimaging.
