The surgical insertion of dental implants requires careful preoperative diagnostics. Particularly, in morphologically difficult situations a CT scan is most useful for the true to scale three-dimensional imaging of the alveolar process and the implant planning. Using a navigation system we are enabled to transfer the preoperative planning and simulation accurately into the operating situs. In t...

Due to the lack of a standardized 3D cephalometric analysis methodology, 2D cephalograms synthesized from cone-beam computed tomography (CBCT) volumes are widely used for in dental CBCT systems. However, compared with conventional X-ray film based cephalograms, such synthetic image contrast and resolution, which impairs landmark identification. In addition, increased radiation dose applied acqu...

OBJECTIVE To determine by low-dose computed tomography (CT) protocol the dental and periodontal effects of rapid maxillary expansion (RME). MATERIALS AND METHODS The sample comprised 17 subjects (7 males and 10 females), with a mean age at first observation of 11.2 years. Each patient underwent expansion of 7 mm. Multislice CT scans were taken before rapid palatal expansion (T0), at the end o...

BACKGROUND The inferior alveolar nerve courses anteriorly within the mandibular canal, providing sensory nerve supply to the mandibular teeth, the buccal mucosa, the gingiva, and the soft tissues of the lower lip and chin. To avoid damage to this nerve and resulting sensory disturbances, its exact location must be known before placement of a dental implant. Imaging modalities currently used to ...
