摘要:: 目的：比较CAD/CAM设计制作的PEEK与钴铬合金铸造支架可摘局部义齿(Removable partial denture，RPD)的临床效果及患者满意度。方法：纳入123例需要进行口腔修复的KennedyⅠ、Ⅱ类患者，其中实验组患者(n=50)采用PEEK制作RPD，对照组患者(n=73)采用钴铬合金制作RPD，分别于修复后6个月、12个月及18个月随访并比较两组患者的牙周指标、主观满意度评价及义齿使用强度变化。结果：实验组患者修复6个月后牙齿菌斑指数平均水平较低，修复12个月、18个月后牙齿菌斑指数和龈沟出血指数平均水平较低，牙齿松动度及牙周探诊深度平均水平两组间比较差异无统计学意义；修复18个月后，实验组较对照组患者对RPD的美观性、轻便性及密合性评价较高（P＜0.05），舒适性、对咀嚼功能、固定功能及语音功能影响的评价两组差异则无统计学意义（P＞0.05）；修复18个月后，实验组义齿强度高于对照组（P＜0.05）。结论：相比钴铬合金材料，PEEK材料制作RPD的临床效果及患者满意度更好，具有更广阔的临床应用前景。

Abstract:: Objective To compare the short-term clinical outcomes and patient satisfaction of PEEK and cast Co-Cr alloy removable partial denture (RPD) designed by CAD/CAM. Methods 123 patients of Kennedy Class I and II requiring restorative dentistry were included, of whom the experimental group (n=50) used PEEK cast RPDs and the control group (n=73) used alloy cast RPDs, and were followed up at 6 months, 12 months and 18 months after the restorative treatment and compared the objective periodontal indexes, subjective satisfaction evaluation and changes in denture intensity between the two groups. Results The average levels of plague index (PLI) and probing depth (PD) in the EG patients were lower after 6 months of treatment, and the average levels of PLI, PD and bleeding index (BI) were lower after 12 months and 18months of treatment. There was no signifi cant diff erence in the average level of tooth mobility (TM) between the two groups. After 18 months of treatment, the patients of EG had higher evaluation on the aesthetics, portability and tightness of RPD (P ＜0.05). and there was no signifi cant diff erence in the evaluation of comfort (P ＞0.05), chewing function, fi xation function and speech function between two groups. While, the EG had higher denture strength after 18 months of treatment (P ＜0.05) . Conclusion Compared to alloy materials, PEEK cast RPD has better clinical outcomes and patient satisfaction, with broader clinical application prospects.
