Abstract：
Reconstruction of maxillary defects can be carried out using a variety of treatment modalities. The choice of modality depends on numerous factors, including the size and extent of the defect, patient characteristics, and existing comorbidities. One of the various options is reconstruction and rehabilitation using a fixed prosthesis supported over a zygomatic implant. In maxillectomy cases, a zygomatic implant can be used to improve the retention of the obturator prosthesis, as the loss of alveolar bone makes it impossible to use conventional endosseous implants. Although zygomatic implants are reported to have high success rates, they are not free of complication. We hereby present a rare complication associated with the placement of a zygomatic implant in a patient with COVID-19-associated mucormycosis who underwent operation. This rare complication has never been reported before. This case report also highlights on the management of complications involving displacement of a zygomatic implant in the infratemporal region.
摘要：
上颌骨缺损的重建可以通过多种治疗方式进行。模态的选择取决于许多因素，包括缺陷的大小和程度，患者因素和现有的合并症。各种选择之一是使用固定假体支撑在zy骨植入物上的重建和康复。在上颌骨切除术中，由于牙槽骨的丢失使其无法使用常规的骨内植入物，因此可以使用zy骨植入物来改善闭孔假体的保留。即使zy骨植入物被提倡具有很高的成功率，他们不是没有并发症。在此，我们提出了一种罕见的并发症，该并发症与COVID-19相关的毛霉菌病的手术患者的zy骨植入物的放置有关。这种罕见的并发症以前从未报道过。该病例报告还重点介绍了涉及颞下地区zy骨植入物移位的并发症的处理。
