Radiographic examination is of particular importance prior to the placement of dental implants, especially when the alveolar ridge is severely atrophied. Accurate assessment of the amount of residual bone can be improved with tomography. A method is described which utilizes templates and marking aids to facilitate the correct positioning of the jaws so as to obtain a true cross-section of the alveolar ridge at the intended implant sites. The same template can be used to determine the location and angulation of the implant at surgery.
在植入牙种植体之前，影像学检查尤为重要，尤其是当牙槽嵴严重萎缩时。断层扫描可提高对剩余骨量的准确评估。本文描述了一种方法，该方法利用模板和标记辅助工具来促进颌骨的正确定位，从而在预期的种植部位获得牙槽嵴的真实横截面。同一模板可用于在手术时确定种植体的位置和角度。
