The most frequent mechanical complications of the bar-implant-retained overdentures are loosening of the bar screws and the need to reactivate the retentive clips. This article describes a technique to construct a new maxillary overdenture to a nonretrievable round-profile implant connecting bar with 2 distally placed attachments. The retainer round-profile bar was nonretrievable due to a worn retaining screw head. Attachment transfer analogs are used to transfer the position of the attachments to the master cast. The technique allows the clinician to construct new overdentures without the need for removal of the implant connecting bar. Reduced chairside time, reduced treatment cost, and increased patient satisfaction are the major advantages of the technique.
杆卡式覆盖义齿最常见的机械并发症是杆螺钉松动以及需要重新激活固位夹。本文描述了一种为带有2个远中放置附着体的不可取出的圆形轮廓种植体连接杆制作新的上颌覆盖义齿的技术。由于固位螺钉头部磨损，固位圆形轮廓杆无法取出。附着体转移代型用于将附着体的位置转移到工作模型上。该技术使临床医生无需移除种植体连接杆即可制作新的覆盖义齿。减少椅旁时间、降低治疗成本和提高患者满意度是该技术的主要优点。
