摘　　要：目的探讨数字化印模与传统印模在牙体缺损修复中的应用效果。方法随机选取2020年1月—2021年6月该院收治的80例牙体缺损患者纳入研究,并以等量电脑随机法均分成A(n=40)、B(n=40)两组。两组均展开口腔修复,A组在传统印模法下展开修复治疗,B组在数字化印模法下展开修复治疗,并对比修复效果。结果B组口腔修复优良率97.50%较A组80.00%更高,差异有统计学意义(χ^(2)=4.507,P=0.034)。B组修复后咀嚼效率(92.48±3.68)%、咬合力(134.51±8.62)1bs、言语功能(44.30±4.77)分,均较A组(80.71±3.51)%、(120.17±8.79)1bs、(39.19±4.25)分高,且差异有统计学意义(t=14.637、7.366、5.058,P<0.001)。而在咀嚼功能恢复时间、言语功能恢复时间、取模护理操作时间、口腔修复后不良反应率相比B组均较A组更少;边缘密合程度、修复体邻接关系、咀嚼效率、咬合力及言语功能评分对比上B组均较A组更佳以上数据对比差异有统计学意义(P<0.05)。结论数字化印模在口腔修复中的应用效果要显著优于传统印模,其更加适用于牙体缺损患者,值得被进一步推广与应用。Objective To explore the application effect of digital impression and traditional impression in the restora⁃tion of tooth defect.Methods Randomly selected a total of 80 patients with dental defects treated in the hospital from January 2020 to June 2021 were included in the study,and they were divided into two groups A(n=40)and B(n=40)by equal-quantity computer randomization method.Oral prosthodontics were performed in both groups,group A was performed under the traditional impression method,and group B was performed under the digital impression method,and the restoration effects were compared.Results The excellent and good rate of dental prosthesis in group B was 97.50%higher than that in group A(80.00%),and the difference was statistically significant(χ^(2)=4.507,P=0.034).After repair,the chewing efficiency(92.48±3.68)%,occlusal force(134.51±8.62)1bs,and speech function(44.30±4.77)were all higher than those in group A((80.71±3.51)%,(120.17±8.79)1bs,(39.19±4.25)),and the difference was statistically significant(t=14.637,14.637,7.366,5.058,P<0.001).Compared with group B,the recovery time of chewing function,the recovery time of speech function,the operation time of model taking nursing,and the adversereaction rate after oral prosthesis were lower than those of group A.The degree of edge closeness,prosthesis adja⁃cency,masticatory efficiency,occlusal force and speech function scores in group B were better than those in group A.All the above data comparisons,the difference was statistically significant(P<0.05).Conclusion The application effect of digital impression in oral restoration is significantly better than that of traditional impression,and it is more suit⁃able for patients with dental defects,and it is worthy of further promotion and application.
