The most frequent mechanical complications of bar-retained implant overdentures (IODs) are fracture of the dentures, loosening of the bar screws, and the need to reactivate the retentive clips. When a bar-retained IOD with an acrylic resin base fractures, the existing bar attachment should be removed to fabricate a new overdenture. So far, no method has been previously described for remaking a fractured mandibular bar-retained IOD without removing the existing bar attachment. This article describes fabrication of a fractured mandibular bar-retained IOD with distally placed ball attachments using attachment transfer analogs. The described technique allows the patient to use the existing overdenture temporarily until the new overdenture is delivered.
杆卡式种植覆盖义齿(IOD)最常见的机械并发症是义齿折断、杆螺丝松动以及需要重新激活固位夹。当带有丙烯酸树脂基的杆卡式 IOD 折断时,应去除现有的杆附着体来制作新的覆盖义齿。到目前为止,还没有描述过在不拆除现有杆附着体的情况下重新制作下颌折断杆卡式 IOD 的方法。本文描述了使用附着体转移体制作带有远中球附着体的下颌折断杆卡式 IOD。所描述的技术可使患者在新覆盖义齿交付之前暂时使用现有的覆盖义齿。
