Thirteen patients who had worn a maxillary conventional denture and mandibular osseointegrated implant-supported overdenture for at least 3 years were evaluated for subjective assessment of fit of the maxillary denture, occlusal integrity, and the status of the anterior maxillary residual ridge. The findings of this study support the view that this combination of prostheses can result in perceived loosening of the maxillary denture, loss of posterior occlusion, increased anterior occlusal pressure, and anterior maxillary bone loss, similar to the effects seen in Combination Syndrome. It is therefore important to ensure that where an implant-supported mandibular overdenture is planned for the edentulous patient, some form of stabilisation of the maxillary arch is also considered.
对13名佩戴上颌传统义齿和下颌骨整合种植体支持覆盖义齿至少3年的患者进行了评估，以主观评价上颌义齿的贴合度、咬合完整性以及上颌前部剩余牙槽嵴的状况。本研究结果支持以下观点：这种假体组合可导致上颌义齿出现松动感、后牙咬合丧失、前牙咬合压力增加以及上颌前部骨质流失，类似于联合综合征中所见的效果。因此，重要的是要确保在为无牙患者计划使用种植体支持的下颌覆盖义齿时，也要考虑对上颌牙弓进行某种形式的稳定处理。
