Dental implant treatment is an indispensable portion of oral rehabilitation in patients who are to undergo reconstructive surgery following the removal of an oral cancerous lesion. However, ideal dental implant treatment cannot be achieved easily in patients who have undergone mandibular reconstruction with a free vascularized flap, usually because of the limited length, height, and width of the bone graft. Shorter implants (< 10 mm in length) therefore are occasionally used in vascularized fibula graft sites. In such cases, however, shorter implants tend to be overloaded, thereby endangering its longevity. In this article, we discuss how a magnetic abutment system was introduced for such a patient. This was designed to discourage overloading of the mandatory short implants. The outcome was successful without overloading 1.5 years after the placing of the mandibular overdenture.
牙种植治疗是口腔癌病变切除后接受重建手术患者口腔修复中不可或缺的一部分。然而，在接受游离血管化皮瓣下颌骨重建的患者中，通常由于骨移植的长度、高度和宽度有限，很难实现理想的牙种植治疗。因此，较短的种植体（长度<10mm）偶尔用于血管化腓骨移植部位。然而，在这种情况下，较短的种植体往往会过载，从而危及其使用寿命。在本文中，我们讨论了如何为这样一位患者引入磁性基台系统。该系统旨在避免强制性短种植体过载。在下颌覆盖义齿植入1.5年后，结果成功，种植体未出现过载情况。
