Implant treatment in the esthetic area requires stable osseointegration and successful esthetic outcomes. Achieving this goal requires careful consideration of accurate implant axis and ideal three-dimensional position. Owing to the high esthetics and the special anatomical structure of the maxillary, a successful implant means a synthesized deli-beration of the residual bone dimensions, soft-tissue thickness, and the relationship of the residual alveolar ridge with the planned restoration. This article offers an in-depth analysis of the clinical decisions and key factors affecting the implant direction in the esthetic area.
美学区种植治疗的目标在于长期稳定的骨结合和理想美学效果。除了种植体植入的理想三维位置，良好的种植体轴向亦是保证美学区种植治疗成功的关键因素。由于上颌前牙区特殊的解剖结构，医生在种植手术时常需要综合考量剩余牙槽骨骨量及形态、软组织特征、修复方式和患者需求等多种因素，从而确定种植体植入的轴向。本文综述了前牙美学区种植体植入轴向的影响因素，并分析了理想修复体长轴与牙槽骨的矢状位置关系，以期为美学区种植决策的制定提供参考。.
