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.
