摘　　要：目的设计制作3D打印截骨导板用于赝复体术中修复BrownⅡ类缺损,评价其临床应用的精准度。方法 8例因肿瘤致BrownⅡ类缺损患者纳入研究,术前设计制作3D打印截骨导板及赝复体,术中在截骨导板引导下完成手术,即刻戴入赝复体修复缺损,将术前虚拟计划与术后CBCT融合,对整体及局部区域行偏差分析评价手术精准度。应用SPSS 23.0软件包对数据进行统计学分析。结果随访期间8例患者肿瘤均未复发,实际手术与虚拟手术最大偏差为(5.26±0.58)mm,平均偏差(1.10±0.25)mm,整体及局部区域差异均无统计学意义(P>0.05)。结论 3D打印截骨导板辅助下的BrownⅡ类缺损修复术取得较好的手术精准度,为上颌骨同期修复重建提供了保证,赝复体术中修复BrownⅡ类缺损取得了良好的临床效果。Objective To assess the accuracy in the immediate rehabilitation of maxillary Brown Ⅱ defects with prosthesis using a 3 D printing osteotomy template. Methods Eight patients with Brown Ⅱ maxilla defect caused by tumor were treated. 3 D printing osteotomy template and prosthesis were designed and fabricated before surgery. The immediate rehabilitation was performed under the guidance of osteotomy template with prosthesis. The postoperative three-dimensional images and the preoperative virtual images were superimposed, and average deviation and maximum deviation of entire and local regions were calculated. The software of SPSS 23.0 was used for statistical analysis. Results No recurrence was found in 8 patients during follow-up. The maximum deviation between the actual and virtual surgery was(5.26±0.58) mm, with an average of(1.10±0.25)mm. No significant difference between the actual and virtual surgery was found among entire and local regions(P>0.05). Conclusion The precise rehabilitation of maxillary Brown Ⅱ defects can be achieved using a prosthesis fabricated with an osteotomy template. The immediate rehabilitation of maxillary Brown Ⅱ defects with prosthesis has achieved good clinical results, which provides a guarantee for the immediate rehabilitation and reconstruction of maxilla.
