Presently, the management of patients with maxilla bone defects of the Cawood V or VI class is achieved using zygomatic or individual implants or through augmentation of the bone. For zygomatic implants, the ORIS criteria represent the most common factor in helping practitioners register success rates. The zygomatic anatomy-guided approach (ZAGA)and zygomatic orbital floor (ZOF) are factors that are crucial to examining the anatomy of a particular patient before the procedure. The aim of thisarticle is to find the statistical relationship between the abovementioned terms and other factors.
A total of 81 patients underwent zygomatic implant procedures in different configurations. The ORIS, ZAGA, and ZOF parameters were compared with other factors such as type of surgery, sex, age, and the anatomy of the zygomatic bone.
Most patients in this article were classified as ZAGA Class 2. The relationships between type of surgery and ZAGA classification, and ZAGA and sinus/maxilla zygomatic implant localization were statistically significant.
The ZAGA and ZOF scales are practical and valuable factors that should be taken into account before surgery, whereas to date, criteria better than the ORIS scale have not been described in terms of the success of zygomatic implants. The ZOF scale might omit perforation of the orbit because this parameter warns a practitioner to be aware of the anatomy of the orbit.
目前，Cawood V 或 VI 类上颌骨缺损患者的治疗可通过颧骨种植体或个体化种植体，或通过骨增量来实现。对于颧骨种植体，ORIS 标准是帮助医生记录成功率的最常见因素。颧骨解剖引导法（ZAGA）和颧骨眶底（ZOF）是术前检查特定患者解剖结构的关键因素。本文旨在找出上述术语与其他因素之间的统计关系。
共有81例患者接受了不同配置的颧骨种植手术。将 ORIS、ZAGA 和 ZOF 参数与手术类型、性别、年龄和颧骨解剖结构等其他因素进行比较。
本文中的大多数患者被归类为 ZAGA 2 类。手术类型与 ZAGA 分类之间以及 ZAGA 与鼻窦/上颌颧骨种植体定位之间的关系具有统计学意义。
ZAGA 和 ZOF 量表是术前应考虑的实用且有价值的因素，而迄今为止，就颧骨种植体的成功率而言，尚未描述比 ORIS 量表更好的标准。ZOF 量表可能会忽略眼眶穿孔，因为该参数提醒医生注意眼眶的解剖结构。
