A zygomatic implant can be an effective device for rehabilitation of the severely resorbed maxilla. If zygomatic implants are used, onlay bone grafting or sinus augmentation would likely not be necessary. Where an anterior onlay bone graft is required, extension of the graft in the posterior region could be reduced. The results of the application of zygomatic implants in 9 patients and clinical evaluation of this therapy are reported.
Nine patients received a total of 15 zygomatic implants. Six to 8 months elapsed for healing before second-stage surgery was performed. Six months after prosthetic treatment, patients' opinions were solicited by means of a questionnaire.
No implant was removed at the time of abutment connection surgery or during the follow-up period. In many cases, the zygomatic implant platform was located palatal to the alveolar ridge. However, no patients complained of any continuing speech impediment following superstructure fabrication. Computed tomograms taken before implant placement and 6 months after implant placement showed no sign of sinusitis in any patient.
The zygomatic implant allows shorter treatment time and hospitalization. However, there can be some problems in the application of zygomatic implants.
It is necessary to investigate long-term clinical prognosis.
颧骨种植体可能是严重吸收的上颌骨修复的有效装置。如果使用颧骨种植体，可能无需进行外置植骨或上颌窦增高术。在需要进行前部外置植骨的情况下，后部区域植骨的范围可以缩小。本文报告了9例患者应用颧骨种植体的结果及该治疗方法的临床评估。
9例患者共植入15枚颧骨种植体。在进行二期手术前经过6至8个月的愈合期。修复治疗6个月后，通过问卷调查征求患者意见。
在基台连接手术时或随访期间，没有种植体被取出。在许多情况下，颧骨种植体平台位于牙槽嵴的腭侧。然而，在制作上部结构后，没有患者抱怨有任何持续的言语障碍。种植体植入前及植入后6个月的计算机断层扫描显示，所有患者均无鼻窦炎迹象。
颧骨种植体可缩短治疗时间和住院时间。然而，颧骨种植体的应用可能存在一些问题。
有必要研究长期临床预后。
