目的评价末端游离缺失患者使用不同印模材制取功能性印模过程中以及义齿修复后的临床疗效。方法选择2011年2—9月在山西医科大学口腔医院修复科就诊的末端游离缺失患者40例,随机分为A组和B组(各20例),分别使用印模膏加藻酸盐印模材和硅橡胶(重体加轻体)制取印模,常规方法制作义齿,比较制取印模过程中以及义齿戴用3个月后患者的满意度。结果制取印模过程中,患者对硅橡胶印模材的满意度高于印模膏加藻酸盐印模材(P<0.05);义齿戴用3个月后,患者对印模膏加藻酸盐印模材组的满意度较硅橡胶印模材组高,差异均有统计学意义(P<0.05)。结论可摘局部义齿修复末端游离缺失时,使用印模膏加藻酸盐印模材制取功能性印模其义齿修复效果好,但制取印模过程中患者感觉用硅橡胶印模材较舒适。由此可见,不同的印模材具有各自的优越性,要根据临床需要进行选择。
OBJECTIVE: To evaluate the clinical efficacy of using different impression materials in the preparation of functional impressions and the denture restoration in patients with terminal deletion. Methods Forty patients with terminal deletion in the Department of Stomatology, Shanxi Medical University Stomatology Hospital from January to September in 2011 were randomly divided into group A and group B (20 cases each) Materials and silicone rubber (heavy body light body) made stamping, denture made by conventional methods, compared with the manufacture of impression and denture wear patients after 3 months of satisfaction. Results During the impression-making process, the patients were more satisfied with the silicone rubber impression material than the impression material plus alginate impression material (P <0.05). After the denture was worn for 3 months, The satisfaction of alginate impression material group was higher than that of silicone rubber impression material group, the difference was statistically significant (P <0.05). Conclusion When the removable partial denture repairs the terminal free deletion, the impression impression is better than the impression impression material plus alginate impression material, but the denture impression is better than the silicone impression impression material Comfortable. Thus, different impression materials have their own advantages, according to clinical needs to choose.
