DrBicuspid.com Imaging & CAD/CAM Insider: Stitched CBCT images accurate as surgical guide

Dear Imaging and CAD/CAM Insider,

When you are working on implants and restorations, what imaging do you use as a surgical guide? A new study reports that stitched small field-of-view cone-beam CT images appear accurate and reliable enough for the fabrication of implant and restoration surgical guides. The authors suggest that these 3D images may provide an affordable and effective way for dentists to ensure successful implant surgeries. Read more in this Insider Exclusive.

Digital radiography is the most common new technology in U.S. dental schools, while CAD/CAM denture fabrication and hard-tissue lasers were the technologies least likely to be taught in the schools, according to a new study in the Journal of Dental Education.

Using functional MRI, Swiss researchers have linked dental pain relief with changes in activity and connectivity in certain parts of the brain, suggesting a distinct role for these brain regions in alleviating dental pain. The researchers presented their findings at the recent International Association for Dental Research (IADR) 2015 General Session. Read more here.

And in an oral session at the IADR meeting, researchers discussed how 3D models of condyles built from MRI scans yielded similar volume and shape as models built from cone-beam CT (CBCT) scans. Read more here.

Also featured in the Imaging & CAD/CAM Community, researchers are using neutron imaging to show how the lower mechanical strength in glass ionomer cements results from the presence of pores and also the increased hydrogen mobility within the material, according to a new study in the journal Scientific Reports.
