摘要：

背景：采用CUBE-X射线探测仪对可摘局部义齿纯钛铸造支架内部进行准确的扫描，对于协助口腔修复技师早期发现铸造支架缺陷，提高纯钛支架铸造的成功率，保证支架质量极其重要。
目的：观察意大利CUBE-X射线探测仪对可摘局部义齿纯钛铸造支架进行内部缺陷扫描观察的可行性和优越性。
方法：利用意大利CUBE-X射线探测仪对本院口腔科门诊近2年来制作的可摘局部义齿纯钛支架共226例进行扫描，检测其缺陷。
结果与结论：扫描发现22例存在严重内部缺陷，这些内部缺陷多呈球型，内表面光滑大部分在纯钛基托内。其中5例有较大气泡，且气泡的大小程度及存在位置与该支架的强度质量具有一定的相关性。使用意大利CUBE-X射线探测仪对可摘局部义齿纯钛支架进行内部缺陷扫描具有一定的可行性，对于协助口腔修复技师早期观察，及早发现铸造支架缺陷具有一定的优越性。

Abstract:

BACKGROUND: CUBE-X meters can accurately scan removable partial denture pure titanium stents, assist dental prosthesis technicians to early observe casting stent defects, increase the success rate of pure titanium casting stents, and ensure the stent quality.
OBJECTIVE: To study the feasibility and superiority of scanning the defects of removable partial denture pure titanium casting stents by Italy CUBE-X survey meter.
METHODS: A total of 266 cases with removable partial denture pure titanium casting stents in the Out-patient Clinic of Prosthodontic Department in recent two years were scanned by CUBE-X survey meter to detect internal defects.
RESULTS AND CONCLUSION: The scanning discovered 22 stents had serious inherent drawbacks, which were ball-shaped, internal surface was smooth and the majority located within pure titanium kittoe. Among them, 5 cases exhibited big air bubble, the air bubble size was positively correlated to the stent strength. It is feasible to detect internal defects of removable partial denture pure titanium stents by CUBE-X survey meter. This method can help dental prosthesis technicians to find the drawbacks of casting stents.
