Intra-oral and panoramic radiographs are most frequently used in oral health care. Yet, the inherent nature of jaws and teeth renders three-dimensional diagnosis essential, especially in relation to oral surgery. Nowadays, this can be accomplished by dental cone beam computed tomography, which provides high-quality images at low radiation doses and low costs. Nonetheless, the effective dose ranges of cone beam computed tomography machines may easily vary from 10 to 1000 μSv, this being equivalent to two to 200 panoramic radiographs, even for similar presurgical indications. Moreover, the diagnostic image quality varies massively among available machines and parameter settings. Apart from the radiodiagnostic possibilities, dental cone beam computed tomography may offer a vast therapeutic potential, including opportunities for surgical guidance and further prosthetic rehabilitation via computer-aided design/computer-aided manufacturing solutions. These additional options may definitely explain part of the success of cone beam computed tomography for oral implant placement. In conclusion, dental cone beam computed tomography imaging could be justified for oral implant-related diagnosis, planning and transfer to surgical and further prosthetic treatment, but guidelines for justification and cone beam computed tomography optimization remain mandatory.
口腔内和全景放射照片在口腔保健中最常使用。然而，颌骨和牙齿的固有性质使得三维诊断成为必要，特别是在口腔外科方面。如今，这可以通过口腔锥形束 CT 来完成，它以低辐射剂量和低成本提供高质量的图像。尽管如此，锥形束 CT 机的有效剂量范围很容易在 10 到 1000μSv 之间变化，这相当于 2 到 200 张全景放射照片，即使对于类似的术前适应症也是如此。此外，可用机器和参数设置之间的诊断图像质量差异很大。除了放射诊断的可能性外，口腔锥形束 CT 还可能具有巨大的治疗潜力，包括通过计算机辅助设计/计算机辅助制造解决方案进行手术引导和进一步修复体的机会。这些附加选项肯定可以部分解释锥形束 CT 在口腔种植体植入方面的成功。总之，口腔锥形束 CT 成像可以为口腔种植体相关的诊断、规划以及手术和进一步修复体治疗的转移提供依据，但有必要制定依据和锥形束 CT 优化的指南。
