The abutment consideration is but one step in the fabrication of a stable base appliance. This step, however, is a vitally important one. If carried out poorly, the casting can be lost and the tooth and periodontal tissues severely damaged or destroyed. All the steps considered in the fabrication of a case are like links of a chain. If one link fails the entire chain (or case) is broken or impaired. When the conditions of proper room for the attachment, crown contour, retention, and criteria of good preparation techniques and design are met, sound abutment considerations will be a strong link in the success of the attachment.
基牙考量只是制作稳定基牙矫治器过程中的一个步骤。然而，这一步骤至关重要。如果操作不当，铸件可能会丢失，牙齿和牙周组织会受到严重损伤或破坏。制作病例时所考虑的所有步骤就像链条的各个环节。如果有一个环节失败，整个链条（或病例）就会断裂或受损。当满足了附着的适当空间、牙冠外形、固位以及良好预备技术和设计标准等条件时，合理的基牙考量将成为附着成功的一个有力环节。
