背景:目前,对CawoodV或VI类上颌骨缺损患者的治疗是使用zy骨或单独植入物或通过增强骨骼来实现的。对于颧骨植入物,ORIS标准是帮助从业人员注册成功率的最常见因素.the骨解剖引导方法(ZAGA)和the骨眶底(ZOF)是在手术前检查特定患者解剖结构至关重要的因素。本文的目的是找到上述术语与其他因素之间的统计关系。
方法:共有81例患者接受了不同构型的颧骨种植手术。ORIS,ZAGA,和ZOF参数与手术类型等其他因素进行比较,性别,年龄,和颧骨的解剖结构。
结果:本文中的大多数患者被归类为ZAGA2级。手术类型与ZAGA分类之间的关系,ZAGA和窦/上颌骨骨种植体定位有统计学意义。
结论:ZAGA和ZOF量表是手术前应考虑的实用和有价值的因素,而到目前为止,没有描述比ORIS量表更好的骨种植体成功的标准.ZOF量表可以省略轨道的穿孔,因为该参数警告从业者注意轨道的解剖结构。
BACKGROUND: 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.
METHODS: 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.
RESULTS: 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.
CONCLUSIONS: 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.
