The conventional method of fabricating implant-retained overdentures involves multiple steps and patient visits. However, the duplication of existing complete dentures could decrease the number of visits and increase patient satisfaction. An existing maxillary implant-retained overdenture was replaced for a 78-year-old man; the existing implant-retained overdenture and his face were scanned at the first visit. The scanned intaglio image was inverted to obtain a virtual maxillary cast and used to fabricate the metal framework of the replacement implant-retained overdenture. Prefabricated artificial teeth were arranged on a 3-dimensional trial denture created from the scan data of the existing implant-retained overdenture. The replacement implant-retained overdenture was fabricated on the metal framework by using the injection molding technique. By using these digital techniques, a stable and esthetic implant-retained overdenture was delivered in 2 visits.
传统的制作种植体支持覆盖义齿的方法需要多个步骤和多次患者就诊。然而，复制现有的全口义齿可以减少就诊次数并提高患者满意度。为一名78岁男性更换了现有的上颌种植体支持覆盖义齿；在首次就诊时对现有的种植体支持覆盖义齿和他的面部进行了扫描。将扫描的组织面图像反转以获得虚拟上颌模型，并用于制作替换的种植体支持覆盖义齿的金属支架。将预制的人工牙排列在根据现有种植体支持覆盖义齿的扫描数据创建的三维试戴义齿上。通过注射成型技术在金属支架上制作替换的种植体支持覆盖义齿。通过使用这些数字技术，仅两次就诊就交付了稳定且美观的种植体支持覆盖义齿。
