数字化印模和传统印模对全口义齿修复临床效果的比较

Comparison of clinical effect of digital impression and traditional impression on complete denture restoration

目的 比较数字化印模和传统印模方式对无牙患者全口义齿修复的临床效果。方法 选取2022年1月至12月江西省抚州抚医口腔医院收治的无牙患者60例为研究对象,采用随机数字表法分成数字化组和传统组,每组30例。数字化组患者佩戴数字化印模法制作的全口义齿,传统组患者佩戴二次印模法制作的全口义齿。比较两组印模舒适感评分和印模用时;比较两组义齿修复临床疗效;比较两组修复前及修复后1、2、3个月的义齿总体满意度;比较两组咀嚼效率和总调磨次数。结果 数字化组印模舒适感评分高于传统组,印模用时短于传统组,差异有统计学意义(P<0.05);两组美观、发音评分比较,差异无统计学意义(P>0.05);数字化组压痛情况、固位稳定性和义齿舒适度评分低于传统组,差异有统计学意义(P<0.05)。整体分析发现:两组义齿修复后总体满意度评分组间、时间及交互作用比较,差异有统计学意义(P<0.05)。进一步两两比较,组内比较:两组义齿修复后不同时间点总体满意度评分比较,差异有统计学意义(P<0.05);组间比较:修复后2、3个月,数字化组义齿总体满意度评分低于传统组,差异有统计学意义(P<0.05)。数字化组咀嚼效率低于传统组,总调磨次数多于传统组,差异有统计学意义(P<0.05)。结论 两种印模法在制作全口义齿过程中各具优势,数字化印模法印模舒适感更好、用时更短,传统印模法制作的全口义齿在义齿舒适度、压痛、固位稳定性及咀嚼效率方面优势更明显。

Objective To compare the clinical effect of digital impression and traditional impression on complete denture restoration for patients with edentulous.Methods Sixty patients with edentulous admitted to Fuzhou Fuyi Stomatological Hospital of Jiangxi Province from January to December 2022 were selected as the study subjects.They were divided into digital group and traditional group by random number table method,with 30 cases in each group.Patients in digital group wore complete dentures made using digital impressions,while patients in traditional group wore complete dentures made using secondary impressions.The impression comfort score and impression time of two groups were compared;the clinical effect of denture restoration was compared between two groups;the overall satisfaction of dentures before restoration and at one,two,and three months after restoration was compared between two groups;and the mastication efficiency and total grinding times were compared between two groups.Results The impression comfort score of digital group was higher than that of traditional group,and impression time was shorter than that of traditional group,and the differences were statistically significant(P<0.05).There were no significant differences in aesthetics and pronunciation scores between two groups(P>0.05);while the tenderness,retention stability,and denture comfort scores of digital group were lower than those of traditional group,and the differences were statistically significant(P<0.05).The overall analysis showed that there were statistically significant differences between groups,time,and interaction in the overall satisfaction score after denture restoration between two groups(P<0.05).Further pound-to-group comparison and intra-group comparison:the overall satisfaction scores after denture restoration of two groups were compared at different time points,and the differences were statistically significant(P<0.05).Inter-group comparison:at two and three months after restoration,the overall satisfaction scores of the digital group were lower than those of traditional group,and the differences were statistically significant(P<0.05).The masticatory efficiency of digital group was lower than that of traditional group,and the total grinding times were higher than those of traditional group,and the differences were statistically significant(P<0.05).Conclusion The two impression methods have their own advantages in the process of making full denture.The digital impression method has better impression comfort and shorter time,while the traditional impression method has more obvious advantages in the aspects of denture comfort,tenderness,retention stability and chewing efficiency.
