Carl Zeiss receives Red Dot Award for OPMI PENTERO 900 Surgical Microscope The European Association for Osseointegration (EAO)hasupdateditsguidelinesontheuseofdiag- nostic imaging in implant dentistry by extending themtocone-beamcomputedtomography(CBCT).

Theassociationapproachedtherevisionofits2002 guidelines after SEDENTEXCT, a collaborative EU research project on the sound and scientifically based clinical use of CBCT in dental imaging, had recommended in 2009 that the EAO review its pre- viousguidelinestotakeintoaccounttheincreasing demandforCBCTindentalpracticeinrecentyears. The new EAO guidelines primarily focus on patient welfare and safety with regard to minimising their exposuretoionisingradiation.Theyweredrawnup tosupportradiologists,aswellasdentistsandtheir assistants,in primary care. “The field of diagnostic imaging is often both very technical and complex. I believe these EAO guide- linesprovideaveryeasilyaccessible,practicaland authoritative approach to the area and offer useful guidance to dentists to help them fulfil their obliga- tions,toactalwaysinthebestinterestsoftheir pa- tients,aswellastobeawareoftheirethicaland le- gal responsibilities,” said Prof. David Harris, lecturer at the Trinity College Dublin Dental School and Hospital and chair of the EAO panel of 14 radiologists and clinicians from all over Europe that convened at the Medical University ofWarsaw in May 2011. According to the panel,all diagnostic imaging car- ries a risk however small; nevertheless, in implant dentistry,itisconsideredessentialtopatientevalu- ation for proposed surgical treatment, the investi- gation of certain complications and prosthodontic planning.Theexpertsthereforehighlightedthatitis necessary to reduce any radiation dose according totheALARAprincipleandtoensurethattheexam- inationofeachpatientisalwaysjustifiedandresults in a net benefit to the patient.Available alternative techniques with the same objective but involving less or no exposure to ionising radiation must also be taken into account,they said. The consensus paper was pre- sented at the 2011 EAO annual con- gress in Athens. It was published online on 20 March in the Clinical Oral Implants Research journal ahead of print.
