An unconventional orthodontic correction can be accomplished by using preexisting provisional restorations, which can be modified for use in active tooth movement or splinted together for orthodontic anchorage. This technique has an advantage over conventional fixed appliance orthodontic therapy because it can accomplish tooth movement concurrently with restorative and periodontal therapy. Consequently, the timing or sequencing of periodontal and restorative treatment is optimal, and the overall treatment is more efficient. The learning objective of this article is to describe the minor tooth movement necessary to achieve the optimum occlusal scheme, crown form, and tooth position for the forces of occlusion to be displaced down the long axis of the periodontally compromised teeth. Once the occlusion, periodontal health, and crown contours for the provisional splinted restoration are acceptable, the final splinted restoration can be similarly fabricated, and it becomes an excellent orthodontic retainer.
通过使用现有的临时修复体，可以完成非常规的正畸矫正，这些临时修复体可进行修改以用于牙齿的主动移动，或通过夹板固定在一起以提供正畸支抗。该技术相对于传统的固定矫治器正畸治疗具有优势，因为它可以在进行修复和牙周治疗的同时实现牙齿移动。因此，牙周治疗和修复治疗的时机或顺序是最佳的，整体治疗效率更高。本文的学习目标是描述实现最佳咬合方案、牙冠形态和牙齿位置所需的轻微牙齿移动，以使咬合力沿牙周受损牙齿的长轴方向传递。一旦临时夹板修复体的咬合、牙周健康和牙冠轮廓达到可接受的程度，就可以以类似的方式制作最终的夹板修复体，并且它将成为一个出色的正畸保持器。
