A radiological technique, using a new CT software program for the evaluation of alveolar process height and width, is presented. Irradiation is kept within acceptable limits when this technique is used. Measurements obtained with this technique were compared with those obtained on panoramic radiographs in 40 "half-jaws" (21 maxillar and 19 mandibular). We found that new indications for implantation emerge in the mandibular region because 'Denta Scan' can sometimes show possibilities to place implants on the buccal side of the canal (2 of 19 mandibular cases) when no possibilities are present above the canal on both the panoramic radiographs and Denta Scan images. In the maxillar region Denta Scan avoids unnecessary interventions by demonstrating the insufficient width of the alveolar ridge, often missed on panoramic radiographs (4 of 21 maxillar cases). Moreover the use of Denta Scan allows the use of implants with optimal length and diameter (23 of the 40 cases), giving better long-term results.
本文介绍了一种放射学技术，该技术使用一种新的CT软件程序来评估牙槽突的高度和宽度。使用该技术时，辐射量可保持在可接受范围内。将该技术获得的测量结果与40个“半颌”（21个上颌和19个下颌）的全景X线片测量结果进行了比较。我们发现，在下颌区域出现了新的种植适应症，因为当全景X线片和Denta Scan图像上牙槽管上方均无种植可能时，“Denta Scan”有时可显示在牙槽管颊侧种植的可能性（19个下颌病例中有2例）。在上颌区域，Denta Scan可通过显示牙槽嵴宽度不足来避免不必要的干预，而这在全景X线片上常常被遗漏（21个上颌病例中有4例）。此外，使用Denta Scan可使用长度和直径最佳的种植体（40例中有23例），从而获得更好的长期效果。
