Application of surgical stents for implant placement via guided flapless surgery is increasing. However, high cost, need for some professional machines, and not taking into account the soft-tissue parameters have limited their application. We sought to design and introduce a technique named in-office guided implant placement (iGIP) to decrease the cost by using available devices in office and enhance the applicability of surgical stents. A customized surgical stent was fabricated based on prosthetic, soft- and hard-tissue parameters by taking into account the amount of available bone (using the computed tomographic [CT] data), soft-tissue thickness and contour (using a composite-covered radiographic stent), and position of the final crown (by diagnostic cast wax up and marking the final crown position with composite). The efficacy of iGIP, in terms of the accuracy of the three-dimensional position of the implant placed in the study cast and in patient's mouth, was confirmed by direct observation and postoperative CT. The iGIP can enhance implant placement in the prosthetically desired position in various types of edentulism. Using this technique minimizes the risk of unwanted consequences, as the soft-tissue thickness and contour are taken into account when fabricating a surgical stent.
通过引导式无瓣手术应用外科种植体支架进行种植体植入的情况正在增加。然而，高成本、需要一些专业设备以及未考虑软组织参数限制了它们的应用。我们试图设计并引入一种名为诊室引导种植体植入（iGIP）的技术，通过使用诊室现有的设备来降低成本，并提高外科种植体支架的适用性。通过考虑可用骨量（使用计算机断层扫描[CT]数据）、软组织厚度和轮廓（使用复合覆盖的放射学支架）以及最终牙冠的位置（通过诊断模型蜡型制作并用复合材料标记最终牙冠位置），根据修复、软组织和硬组织参数制作定制的外科种植体支架。通过直接观察和术后CT证实了iGIP在研究模型和患者口腔中植入种植体三维位置准确性方面的有效性。iGIP可以在各种类型的牙列缺失中提高种植体在修复理想位置的植入。使用该技术可将不良后果的风险降至最低，因为在制作外科种植体支架时会考虑软组织厚度和轮廓。
