The analysis of the degradation of HA coating of a loaded implant
摘要
Abstract
Objective:To analyze the degradation of hydroxyapatite(HA)coating of a failed implant after long term function. Methods:The HA-coated implant functioning for 23 years was extracted due to peri-implantitis. The surface was an-alyzed by gross observation,scanning electron microscopy( SEM) for morphology,and energy dispersive spectrometer( EDS) for elements analysis respectively. Results:By gross observation and SEM test,no obvious coating-like structure was found,ex-cept for some micro-convexes. EDS analysis demonstrated that calcium and phosphorus were detected(14. 27%,9. 15%) at the convexes. For most of the areas,no or trace calcium and phosphorus(1. 17%,0. 82%) was found. Conclusion:The spe-cific case analysis showed that HA coating of the implant almost degraded after the long term function in the human body.关键词
