This report of four clinical cases aims to illustrate the use of a lateral implant as a solution for implant overdentures in the mandible in different clinical situations. The first two cases describe the clinical situations of patients wearing two-implant mandibular overdentures until the failure of one of the implants, one due to implant loss and the other due to a fracture of an abutment screw, and how the conditions were managed. The third case illustrates the placement of a single implant to retain an overdenture, where a midline implant, as originally planned, was not feasible due to anatomic reasons. The final case describes the use of a lateral implant to support and retain a single-implant mandibular overdenture. The four cases demonstrate that a single lateral implant can be utilized as sole retention in cases of a failing contra-lateral implant and as an alternative to a single implant in the midline.
本报告介绍了四个临床病例，旨在说明在不同临床情况下，将侧向种植体作为下颌种植覆盖义齿解决方案的应用。前两个病例描述了两位患者的临床情况，他们均佩戴了两颗种植体的下颌覆盖义齿，直到其中一颗种植体发生失败：一个是由于种植体脱落，另一个是由于基台螺丝断裂，以及如何处理这些情况。第三个病例说明了放置单个种植体以保留覆盖义齿的情况，由于解剖原因，最初计划在中线放置种植体，但不可行。最后一个病例描述了使用侧向种植体来支持和保留单个种植体的下颌覆盖义齿。这四个病例表明，在对侧失败的种植体情况下，单个侧向种植体可用作唯一的保留体，并且可以作为中线上单个种植体的替代方案。
