摘要
目的报道以修复为导向的上前牙美学区数字化即刻种植即刻修复技术。方法通过口内数字化光学扫描印模,结合CBCT扫描,CAD/CAM技术虚拟植入种植体、设计个性化钛基台穿龈形态及临时修复体,并生成种植手术导板及临时牙,辅助完成微创手术。结果本技术达到拔牙后即刻种植即刻修复的效果。即刻修复临时牙冠能够在病人第二次就诊手术后即刻完成,最终实现保存软组织轮廓的美学种植修复。结论种植应用数字化技术改变了以往工作流程,使美学种植修复更加简单、高效、精确。
Objective To describe a novel workflow for the anterior dental esthetics in immediate implant and im?mediate aesthetic restoration with digital technique.Methods Before the implant placement,a intra?oral optical scan(IOS)combined with CBCT was performed to virtually design the3D implant position and restoration.A surgical guideand an individualized Ti abutment restoration was CAD/CAM?fabricated out of the PMMA?based in a fully digital work?flow and seated at the stage of minimal invasive surgery.Results The technique achieved immediate implant and im?mediate restoration after tooth extraction.Immediate restoration of temporary crown could be completed immediately insecond patient visit after the operation,finally realized the aesthetic implantation with preserved soft tissue contour.Conclusion The fully digital technique changed the conventional workflow which achieves more efficiency and betteraesthetic effect.
