摘要
目的:探讨3D打印技术辅助对上颌骨缺损修复手术骨增量的效果及精确度的影响。方法:选取2020年6月-2023年6月笔者医院收治的上颌骨缺损修复重建的患者48例为此次试验的对象。对照组采取常规颏部取骨到上颌移植修复治疗,观察组采用样品实验法经3D打印1∶1比例的颌骨作为模型样本,通过3D打印导板辅助种植体植入模拟牙槽骨骨移植手术。比较两种手术方法患者的骨增量变化、下颌各位点移动距离及种植体偏离距离、角度。结果:观察组牙槽骨高度、骨宽度变化值均大于对照组(P<0.05);与对照组相比,观察组手术前后下颌各位点(A、B、C、D、E)的移动距离均明显减少(P<0.05);精确度结果显示,观察组种植体偏离距离、偏离角度均小于对照组,且差异具有统计学意义(P<0.05)。结论:3D打印技术辅助对上颌骨缺损修复手术骨增量的效果显著,有效提高手术的精准度,从而提高手术效果。
Objective To explore the influence of 3D printing technology on the effect and accuracy of bone increment in maxillary defect repair surgery.Methods This study included 48 patients with maxillary defect repair and reconstruction from June 2020 to June 20203.In the control group,conventional mental bone extraction to maxillary transplantation was used for repair.The observation group used the 1:1 ratio of jaw bone by 3D printing as the model sample,and 3D printing guide plate assisted implant implantation to simulate alveolar bone transplantation.Compare the bone increment change,movement distance of jaw and implant deviation distance between the two surgical methods.Results The change values of alveolar bone height and bone width in the observation group were greater than those of the control group(P<0.05).Compared with the control group,the movement distance of the jaw points(A,B,C,D,E)before and after the observation group was significantly reduced(P<0.05).The precision results showed that the implant bias distance and bias angle in the observation group were less than those of the control group,and the difference was statistically significant(P<0.05).Conclusion 3D printing technology can repair the maxillary bone defect,effectively improve the accuracy of surgery,and thus improve the surgical effect.
