Different computer-assisted implant-placement procedures are currently available. These differ in software, template manufacture, guiding device, stabilization and fixation. The literature seems to indicate that one has to accept a certain inaccuracy of ±2.0 mm, which seems large initially but is clearly smaller than for nonguided surgery. A reduction of accuracy to below 0.5 mm seems extremely difficult. A common shortcoming identified in the studies included in this review is inconsistency in how clinical data and outcome variables are reported. Another limitation is the small number of comparative clinical studies. In order to find the best guiding system or the most important parameters for optimal accuracy, more randomized clinical trials are necessary. Information on cost-effectiveness and patient-centered evaluations (i.e. questionnaires and interviews) must also be included.
目前有不同的计算机辅助种植体植入程序。这些程序在软件、模板制造、引导装置、稳定性和固定性方面有所不同。文献似乎表明，人们必须接受±2.0mm 的一定误差，这在最初似乎很大，但显然比非引导手术小。将精度降低到 0.5mm 以下似乎极其困难。本综述纳入的研究中共同存在的一个缺点是临床数据和结果变量的报告方式不一致。另一个限制是比较性临床研究的数量较少。为了找到最佳的引导系统或实现最佳精度的最重要参数，需要进行更多的随机临床试验。还必须包括关于成本效益和以患者为中心的评估（即问卷和访谈）的信息。
