摘　　要：目的探索通过改进传统印模流程为集中数字化印模流程以提高临床效率的效果。方法北京大学深圳医院口腔医学中心修复科对制取印模的临床流程进行了改进,即将由医生用印模材料为患者制取印模改进为一位技师为全科所有患者集中制取数字化印模。统计临床流程改进前单颗后牙二氧化锆全冠修复的患者印模制取所需的医生椅旁时间、集中数字化印模制取所需的时间、患者的舒适度、修复体的邻接关系、咬合接触关系及戴牙所需的时间。评价集中数字化印模是否会降低修复体的质量及增加戴牙时长。结果医生椅旁为患者制取传统印模的平均时长为(9.98±1.41)min,集中数字化印模制取平均时长为(5.98±1.49)min,印模制取时间更短(P<0.05);相较传统印模,集中数字化印模让患者感觉更舒适(P<0.05);集中数字化印模修复体的邻接关系更合适(P<0.05),但2组间咬合关系和戴牙所需时间的差异无统计学意义(P>0.05)。结论对单颗后牙二氧化锆全冠修复的患者,通过集中数字化印模可以提高临床效率。同时印模制取的时间更短,患者感觉更舒适,也保证了修复体的质量。Objective This study aims to explore the effect of improving clinical efficiency by replacing traditional impression workflow with centralized digital impression workflow.Methods The department of prosthodontics in Center of Stomatology,Peking University Shenzhen Hospital has improved the clinical workflow by replacing the traditional impression made by doctors using impression materials for each patient with a centralized digital impression made by one technician for all patients in the department.This cross-sectional study recorded the chairside time required for impression taking in patients undergoing single posterior zirconia full crown restoration before clinical process improvement;the time required for centralized digital impression production;the comfort level of patients;and the adjacency relationship,occlusal contact relationship,and time required for prostheses adjusting(i.e.,whether centralized digital impressions would compromise the quality of pro-stheses and increase the time of prostheses adjusting).Re-sults The average time to make a traditional impression was(9.98±1.41)min,and the average time required for each patient to make a centralized digital impression was(5.98±1.49)min,which was shorter than that to used make a traditional impression(P<0.05).Centralized digital impression made patients feel more comfortable compared with traditional impression(P<0.05).The adjacency relationship of restorations by centralized digital impression was more appropriate(P<0.05),and no significant difference in occlusal relationship was found(P>0.05).The time required for adjusting prostheses also had no significant differences(P>0.05).Conclusion Centralized digital impression can improve clinical efficiency for patients undergoing single posterior zirconia crown restoration.The time for impression taking is shorter,and patients feel more comfortable without compromising the quality of the prostheses.
