Historically, predoctoral and advanced dental education programs used two-dimensional panoramic and periapical radiographs for implant planning. Three-dimensional (3D) Cone Beam Computed Tomography (CBCT) imaging has improved visualization of anatomic structures that can positively influence implant planning and surgical implant placement. The aim of this study was to assess how U.S. postdoctoral periodontics programs have incorporated CBCT technology into their curricula. A ten-question survey was sent to all 57 U.S. postdoctoral periodontics programs in November-December 2018. Thirty-seven responses were received, for a 65% response rate. All participating programs reported providing residents access to CBCT machines, and most of their residents received some training in the acquisition and interpretation of CBCT images. Nearly all (95%) participating programs provided training to apply implant planning software. Among the participating programs, 14% reported using a surgical guide fabricated with a CBCT scan 76-100% of the time, and 60% reported obtaining a CBCT scan for implant cases 76-100% of the time. These results suggest that, while residents are receiving training in CBCT and implant planning, it is not used often. There may be merit in adopting the American Academy of Oral and Maxillofacial Radiology's recommendation to use 3D imaging for all implant planning, with CBCT as the imaging modality of choice.
