摘要
目的:探讨数字化三维打印(D3DP)技术为牙列缺损患者进行个体化义齿修复,在提升修复效率和美学效果方面的临床应用价值。方法:选取2023年6月—2025年5月青岛市第五人民医院收治的150例牙列缺损患者,按随机数表法分为研究组和对照组,每组75例。研究组接受全程数字化种植修复(数字化导板引导手术+口内扫描取模+计算机辅助设计+3D打印修复体),对照组接受传统种植修复(自由手植入手术+传统聚醚取模+失蜡法铸造修复体)。比较两组患者的手术效率、修复体质量、并发症发生率及美学评分。结果:研究组种植体植入用时、修复体戴入用时及调改次数优于对照组(P<0.05);研究组修复体边缘适配性优良率高于对照组,内部密合性优于对照组(P<0.05);研究组并发症发生率低于对照组(P<0.05);研究组红色美学评分、白色美学评分及美学总分均高于对照组(P<0.05)。结论:D3DP技术在牙列缺损患者个体化义齿修复中应用效果良好,可提升手术效率与修复体质量,降低并发症发生率,且美学效果更佳。
Objective:To explore the clinical application value of digital three-dimensional printing(D3DP)technology on repair efficiency and aesthetic outcomes of personalized denture repair in patients with dentition defects.Methods:150 patients with dental defects who were treated at Qingdao Fifth People’s Hospital from June 2023 to May 2025 were selected.They were divided into the study group(n=75)and the control group(n=75)using the random number table method.The study group underwent fully digital implant restoration(digital guide plate-assisted surgery+intraoral scanning+computer-aided design+3D-printed prosthesis),while the control group received traditional implant restoration(freehand surgery+traditional polyether impression+lost-wax casting).The surgical efficiency,prosthesis quality,complication rates,and aesthetic scores of the two groups were compared.Results:The study group showed superior implant placement time,prosthesis delivery time,and adjustment times compared to the control group(P<0.05).The study group also showed higher excellent rates for prosthesis marginal adaptation,better internal fit,and lower complication rates(P<0.05).Additionally,the study group scored higher in pink aesthetic,white aesthetic,and overall aesthetics(P<0.05).Conclusion:D3DP technology has favorable application effects in personalized denture repair for patients with dentition defects,which can enhance surgical efficiency,prosthesis quality,and aesthetic outcomes while reducing complication rates.
