摘　　要：目的探讨3D打印种植导板对前牙即刻种植患者种植体植入位置和角度的影响。方法纳入本院于2018年6月至2020年6月收治的58例行前牙即刻种植患者,按随机化原则分作对照组及观察组,均于种植手术前拍摄锥形束CT预先规划种植体方案并记录虚拟种植体位置及角度,对照组未使用3D种植导板,予以常规种植,观察组于3D打印种植导板辅助下种植,计算两组实际植入位置和角度与术前规划失准值进行比较,并评估术后1个月、3个月两组种植体周围软组织红色美学(PFS)评分、主观舒适度评分。结果观察组位置中顶部、底部及纵向失准值及角度失准值均较对照组更低,差异有统计学意义(P<0.05);于术后1个月、3个月,观察组种植体周围软组织PFS评分及主观舒适度评分均高于对照组(P<0.05)。结论前牙即刻种植患者应用3D打印种植导板行种植体植入,顶部、底部、纵向位置及角度失准值降低,可提升种植体植入精度,且PFS、主观舒适度评分上升,种植体植入美观性及舒适度均有提高。Objective To investigate the effect of 3D printing implant guide on the position and angle of implant placement in patients with immediate anterior tooth implantation.Methods 58 patients who underwent immediate anterior tooth implantation admitted to our hospital from June 2018 to June 2020 were enrolled.They were divided into the control group and the observation group according to the principle of randomization,and they were all pre-planned with cone-beam CT before implant surgery.Implant plan and record the position and angle of the virtual implant.The control group did not use the 3D implant guide and received conventional implants.The observation group was implanted with the aid of the 3D printed implant guide.The actual implant positions and angles of the two groups were calculated to be inaccurate with the preoperative planning.The values were compared,and the red aesthetic(PFS)scores and subjective comfort scores of the soft tissues around the implants in the two groups were evaluated at 1 month and 3 months after surgery.Results The top,bottom and longitudinal misalignment values and angular misalignment values of the observation group were lower than those of the control group,and the difference was statistically significant(P<0.05);at 1 month and 3 months after surgery,the PFS score and subjective comfort score of the soft tissue around the implants in the observation group were higher than those of the control group(P<0.05).Conclusion Patients with immediate anterior teeth implants can use 3D printed implant guides to implant implants.The top,bottom,longitudinal position and angular misalignment can be reduced,which can improve the accuracy of implant placement,and the PFS and subjective comfort scores will increase.Implant aesthetics and comfort are improved.
