Pathologically movable anteriors with horizontal root fracture can be fixed by endodontal bone pins, unless the fracture is located in the cervical third of the root canal. The apical root fragment needs to be removed for fixation. As the anatomic conditions in monkeys do not permit adequate preparation of the root canal required for endodontal pin fixation, the histological findings can be transferred to man to a limited extent only.
对于伴有水平根折的病理性可动前牙，可采用根管骨针固定，除非骨折位于根管的颈三分之一处。为进行固定，需要去除根尖根折碎片。由于猴子的解剖条件不允许进行根管骨针固定所需的充分根管预备，因此组织学研究结果只能在有限程度上应用于人类。
