A 48-year-old woman sought treatment because her staple implant-retained overdenture was no longer retentive, and the denture was worn over the abutments. After unsuccessfully attempting to move the retentive nuts along the transosseous posts of the staple implant, the posts were cut off at the level of the bone. Two endosseous implants were placed around the staple implant, and a new implant-retained overdenture was fabricated and inserted using ball attachments for retention. This article describes the treatment for this patient, who has been wearing the new dentures successfully for the past 4 years.
一位 48 岁女性前来就诊，原因是她的卡环固位式覆盖义齿不再固位，且义齿覆盖在基台上。在尝试沿卡环固位钉的贯穿牙槽骨部分移动固位螺母失败后，将这些钉截断至骨面以下。在卡环固位钉周围植入两颗种植体，使用球型附着体固位制作并植入新的覆盖义齿。本文介绍了对该患者的治疗，患者佩戴新义齿已超过 4 年，效果良好。
