Software in combination with imaging techniques is used increasingly for diagnosis, planning and treatment in oral implantology. Computer-aided surgery allows a great accuracy in implant positioning to be obtained, taking advantage of the amount of bone available and facilitating minimally invasive surgery. It is a significant aid in determining implant number, location, angle and characteristics. A CT with a radiographic template positioned in the mouth is made for the patient. Data are stored on a CD in DICOM 3 format and then introduced in the computer where implant treatment will be planned, using the chosen software. Navigation improves surgical accuracy through the aid of software based on the images captured from CT or MRI and a surgical instrument tracking system. Infrared light-emitting diodes are connected to rotatory instruments and to the patientvs template. Information is collected by special-purpose cameras, allowing the procedure to be viewed in real time on a monitor. It is useful in situations where an exact implantation is demanded, such as anatomical limitations, little space, atrophic maxillae, sinus lifts or zygomatic implants. Articles reviewed agree in emphasizing the reliability and accuracy of the planning and computer-assisted navigation systems available in the market. Nevertheless, many applications are still in the development phase.
软件与成像技术相结合，在口腔种植学的诊断、治疗规划和治疗中越来越多地得到应用。计算机辅助手术利用可用骨量，能够实现极高的种植体定位精度，并有助于开展微创手术。这在确定种植体数量、位置、角度和特性方面是一项重要辅助手段。要为患者制作一张置于口腔内的带有放射模板的CT扫描。数据以DICOM 3格式存储在一张光盘上，然后导入计算机，利用所选软件进行种植治疗规划。导航借助基于CT或MRI所采集图像以及手术器械跟踪系统的软件，提高手术精度。红外发光二极管连接到旋转器械和患者的模板上。信息由专用摄像头采集，从而能够在监视器上实时查看手术过程。在需要精确植入的情况下，如存在解剖学限制、空间狭小、上颌骨萎缩、上颌窦提升或颧骨种植时，它很有用。所综述的文章一致强调市场上现有规划和计算机辅助导航系统的可靠性和准确性。然而，许多应用仍处于开发阶段。
