摘　　要：目的:通过对厦门医学院附属口腔医院近5年使用口内扫描和传统印模方式制作的固定修复体的返工率进行比较分析,为口内扫描的临床应用提供参考。材料和方法:收集本院近5年烤瓷熔附金属(porcelain fused to metal,PFM)全冠和全瓷冠的所有技工单,包括各种原因要求重新制作的返工单。将其分为口内扫描组和传统印模组,每组又分为PFM组和全瓷冠组,分别计算各组的返工率,利用卡方检验进行统计学分析。同时,将近5年的数据按时间顺序分为5组,分别统计各组返工率。结果:本研究共收集技工单50347单,其中传统印模组22619单(包括14356单PFM,8263单全瓷冠),口内扫描组27728单(包括6303单PFM,21425单全瓷冠)。本研究中总返工率为5.06%,其中口内扫描组返工率为4.01%,传统印模组返工率为6.35%;PFM组中,口内扫描组返工率为2.98%,传统印模组返工率为5.58%;全瓷冠组中,口内扫描组返工率为4.32%,传统印模组返工率为7.68%。近5年来,传统印模技工单逐年减少,返工率稍呈下降趋势;口内扫描技工单逐年显著增多,且返工率呈明显下降趋势。结论:基于本院近5年数据研究表明,口内扫描法较传统印模法在固定修复中返工率更低,可广泛应用于临床固定修复。Objective:By comparing the failure rate of fixed restorations made by intraoral scanning and traditional impression in Stomatological Hospital of Xiamen Medical College over the past 5 years,the study provides a reference for wide clinical application of intraoral scanning.Materials and methods:Acquiring the laboratory orders for porcelain fused to metal(PFM)full crowns and all-ceramic crowns over the past 5 years,including failed orders that required re-production for various reasons.Dividing them into intraoral scanning and traditional impression groups,while each group was subdivided into PFM and all-ceramic crown groups.The failure rate was calculated separately,followed by statistical analysis(chi-square test).At the same time,the data of the past 5 years was divided into 5 groups in chronological order,and the laboratory orders and failure rates of intraoral scanning and traditional impression of each group were calculated.Results:A total of 50347 laboratory orders were collected,including 22619 orders for traditional impression group(14356 PFM and 8263 all-ceramic crown),and 27728 orders for intraoral scanning group(6303 PFM and 21425 allceramic crown).The total failure rate was 5.06%,of which the failure rate of the intraoral scanning group was 4.01%,while 6.35%for traditional one.The failure rate of the intraoral scanning group in the PFM group was 2.98%,and the traditional impression group was 5.58%.In the all-ceramic crown group,the failure rate of the intraoral scanning group was 4.32%,while 7.68%for traditional one.In the past five years,the traditional impression laboratory orders have been decreasing,while the failure rate showed a slight downward trend.The intraoral scanning laboratory orders have increased yearly,and the failure rate has shown a significant downward trend.Conclusions:Based on the limited data of our hospital over the past 5 years,the research shows that intraoral scanning has a higher success rate in fixed restoration than traditional impression,and could be widely used in clinic
