Oroantral communication (OAC) rarely occurs long after implant placement. The present report describes the rare etiology and the difficulty of the diagnosis of an uncommon OAC occurring 10 years after the implant placement in the posterior maxilla. The difficulty of the diagnosis lies in the absence of clinical symptoms of sinusitis and presence of multiunit prosthesis hiding implant failure. This case report supports the need for sinus check-up during a routine implant examination.

种植体植入后很长时间才出现的口腔上颌窦瘘（OAC）很少见。本报告描述了一种罕见的病因，以及诊断在上颌后牙区种植体植入10年后发生的罕见OAC的困难。诊断的困难在于缺乏鼻窦炎的临床症状，以及多单位修复体掩盖了种植体失败的情况。本病例报告支持在常规种植体检查期间进行鼻窦检查的必要性。
