Abstract：
OBJECTIVE: Prosthetics for patients after oncological resection of the upper jaw is a complex problem associated with the physiological and anatomical separation of the oral cavity and the nasal/paranasal region. This study reports the clinical results of the use of the zygomatic implants for prosthetic rehabilitation in patients with maxillectomy due to upper jaw tumors.
METHODS: The study included 16 patients who underwent prosthetic rehabilitation using a zygomatic implant after maxillectomy period from 2021 to 2023. After the tumor was removed, immediate surgical obturators were placed. Main prosthetic rehabilitation was performed 6-12 months after tumor removal, but before that, a temporary obturator was made and used. Six-twelve months after tumor resection, 1-4 zygomatic implants were inserted into the zygomatic bone unilaterally or bilaterally. A total of 42 zygomatic implants were installed, 2 of which were unsuccessful and were removed in 1 patient. The implants were placed using the surgical guide, which was planned and prepared digitally.
RESULTS: No postsurgical complications were seen, and the patients were discharged from the hospital after 7-10 days. The patients were able to return to a normal diet (hard food) after just 7 days following surgery, with no further complaints regarding function or pain, apart from the residual edema caused by the intervention.
CONCLUSIONS: The use of prostheses fixed on zygomatic implants in patients with maxillary defects is an effective method of prosthodontic rehabilitation in complex clinical cases after maxillectomy.

摘要：
目的：上颌肿瘤切除术后患者的假肢是一个复杂的问题，与口腔和鼻/鼻旁区的生理和解剖分离有关。本研究报告了由于上颌肿瘤而进行上颌切除术的患者使用zy骨植入物进行假体康复的临床结果。
方法：该研究包括16例患者，这些患者在2021年至2023年的上颌骨切除术后使用zy骨植入物进行了修复。肿瘤切除后,立即放置手术闭塞器。肿瘤切除后6～12个月进行主要修复,但在此之前,制造并使用了一个临时闭塞器。肿瘤切除后6-12个月,将1-4个of骨植入物单侧或双侧插入the骨。总共安装了42个颧骨植入物，其中2例不成功，1例患者被切除。植入物是用手术导向器放置的,这是数字计划和准备的。
结果：未发现术后并发症，患者在7-10天后出院。手术后7天，患者能够恢复正常饮食（硬食物），没有关于功能或疼痛的进一步抱怨，除了干预引起的残余水肿。
结论：对于上颌骨缺损患者，在颌骨缺损后的复杂临床病例中使用固定假体修复是一种有效的修复方法。
