Practical CAD/CAM surgical guidance using cone-beam computed tomography.
Abstract:
Emerging methods for transfer of CT scanning implant planning into CAD-CAM surgical guide fabrication will be presented. Recent research demonstrates that they are precise, allowing for accurate transfer of planning to surgery. In addition, new approaches are becoming available to render guide fabrication more practical. A new cone-beam computed tomography (CT) scanner technology will be presented, together with recent results of radiation dose and accuracy studies. In contrast to costly helical scanners, this CT scanner acquires all head and neck regions with a better precision, high contrast and low radiations.
The low-cost CT scanner may be placed in a dental office. Referral to large hospital units is not necessary anymore,patient fear of the examination is eliminated and cost is reduced. Therefore, it will impact dentists by offering better access to computed tomography images with outstanding implications to implant and other dental diagnosis, which will be illustrated during the lecture. CAD-CAM surgical guides have been utilized for large cases because they require a CT survey and wide edentulous areas. However, newer techniques allow for their utilization in all cases and other in-office precise surgical guide fabrication methods are emerging, which will make fabrication less costly and more practical to dentists. This clinical presentation will introduce new methods for surgical guide fabrication and cone-beam computed tomography. In conclusion, we will introduce a vision for an independent in-office setup allowing the dentist to obtain high quality imaging and accurate implant surgical guides.
