This case report describes an alternative surgical approach which can avoid the need for secondary regenerative techniques for ridge augmentation when planning treatment for dental implants. Our patient had a hopeless maxillary left central incisor, which was subsequently extracted in preparation for implant restoration. The site had a significant defect, which was treated at the time of extraction with a combination of a xenograft and a cortical chin graft. The goal was to preserve the residual ridge contour to avoid a compromise in implant fixture placement and maximize function and esthetics.
本病例报告描述了一种替代手术方法，在为牙种植体规划治疗时，该方法可避免进行二次牙槽嵴增高再生技术。我们的患者上颌左侧中切牙无可保留价值，随后将其拔除，为种植修复做准备。拔牙位点存在明显缺损，拔牙时采用了异种骨移植和颏部皮质骨移植相结合的方法进行治疗。目的是保留剩余牙槽嵴轮廓，避免影响种植体植入位置，并使功能和美观最大化。
