A retrospective study to analyze the clinical performance of 3D printed complete dentures in edentulous patients compared with conventional complete dentures regarding postinsertion visits and patient reported outcomes.
Electronic charts were reviewed to analyze 420 (maxilla 270, mandible 150) heat-polymerized conventional complete dentures (CCD) inserted between July 1, 2015 and June 30, 2016 and 217 (maxilla 130, mandible 86) 3D printed complete dentures (PCD) inserted between July 1, 2017 and June 30, 2018. Number of remakes, number of postinsertion adjustments, type and number of repairs, and patient reported complications were compared between two types of complete dentures. The frequency of denture repair and patient reported complications were analyzed using chi-square of independence test.
The frequency of pain and visible ulcer lesions in the maxilla was determined to be 46.67% with CCD and 36.15% in PCD (p = 0.047). There was no statistical significance in other items. The majority of esthetic concerns was dissatisfaction with the shape of dentures with CCD (4.67%) and they had statistically significant, less frequent, esthetic problems than PCD (11.63%) (p = 0.047).
Similar clinical performance was recorded between the two groups, but the overall pain and visible ulcer lesions were less in the printed complete dentures then the conventionally processed dentures. However, the esthetic aspect was better in conventionally processed complete dentures.
一项回顾性研究，分析了与传统全口义齿相比，3D 打印全口义齿在义齿修复后复诊和患者报告结局方面的临床性能。
通过电子病历分析了 2015 年 7 月 1 日至 2016 年 6 月 30 日期间植入的 420 副（上颌 270 副，下颌 150 副）热聚合传统全口义齿（CCD）和 2017 年 7 月 1 日至 2018 年 6 月 30 日期间植入的 217 副 3D 打印全口义齿（PCD）。比较了两种全口义齿的重衬次数、修复次数、修复类型和数量以及患者报告的并发症。使用独立性卡方检验分析义齿修复和患者报告并发症的频率。
上颌义齿疼痛和可见溃疡的发生率为 CCD 组 46.67%，PCD 组 36.15%（p=0.047）。其他项目无统计学意义。对美学的关注主要是对 CCD 义齿形状的不满意（4.67%），与 PCD 组（11.63%）相比，他们的美学问题明显较少，且具有统计学意义（p=0.047）。
两组之间记录的临床性能相似，但 3D 打印全口义齿的总体疼痛和可见溃疡发生率低于传统加工的全口义齿。然而，传统加工的全口义齿在美学方面更好。
