摘　　要：美学区即刻种植属于高度复杂病例,自由手操作下很难将种植体植入到理想的三维位置,而数字化种植导板可以显著提高即刻种植的精确性,实现“以终为始”的种植修复理念。患者左上中切牙因外伤导致根折,在全程导板引导下完成不翻瓣即刻种植,术中利用自体牙冠进行即刻修复。术后6个月,对临时修复体穿龈轮廓调整后,使用数字化间接印模技术完成穿龈轮廓的复制和转移。最终使用角度螺丝通道基台及全瓷冠完成修复。在3个月随访期内,本病例获得了良好的“粉白”美学修复效果,影像学检查种植体骨结合良好,未见边缘骨吸收。该病例在数字化技术辅助下,简化了即刻种植手术及取模修复流程,实现了种植体的精准植入,获得了良好的美学修复效果。Immediate implant placement in the esthetic zone is highly complexed case,it is difficult to place the implant in the ideal three-dimensional position with free-hand operation,while the digital implant guide can significantly improve the precision of immediate implant placement.The patient's left upper central incisor was fractured due to trauma.The immediate implant placement was completed without flap surgery under the guidance of full digital implant guide,and the immediate restoration was performed using the autogenous crown.Six months after surgery,emergence profile was copied and transferred using digital indirect impression technique after emergency profile was adjusted by temporary restoration.The final restoration was completed using ASC abutment and ceramic crown.During three-month follow-up period,the patient achieved a good"pink and white"aesthetics core and good osseointegration.The case was digitally assisted to simplify the procedure of immediate implant surgery,to achieve precise implant placement and to obtain good esthetic restorative results.
