Abstract

OBJECTIVES

To develop an artificial tooth-periodontal ligament (PDL)-bone complex (ATPBC) that simulates clinical crown displacement.

MATERIAL AND METHODS

An ATPBC was created. It had a socket hosting a tooth with a thin layer of silicon mixture in between for simulating the PDL. The complex was attached to a device that allows applying a controlled force to the crown and measuring the resulting crown displacement. Crown displacements were compared to previously published data for validation.

RESULTS

The ATPBC that had a PDL made of two types of silicones, 50% gasket sealant No. 2 and 50% RTV 587 silicone, with a thickness of 0.3 mm, simulated the PDL well. The mechanical behaviors (1) force-displacement relationship, (2) stress relaxation, (3) creep, and (4) hysteresis were validated by the published results.

CONCLUSION

The ATPBC simulated the crown displacement behavior reported from biological studies well.

摘要

目的

开发一种模拟临床牙冠位移的人工牙-牙周韧带（PDL）-骨复合体（ATPBC）。

材料和方法

创建了一个 ATPBC。它有一个容纳牙齿的牙槽，牙齿之间有一层薄薄的硅混合物，模拟 PDL。复合体附着在一个可以向牙冠施加受控力并测量牙冠产生的位移的装置上。牙冠位移与先前发表的数据进行比较以验证。

结果

由两种类型的硅酮（50%垫圈密封剂 No.2 和 50%RTV 587 硅酮）组成、厚度为 0.3 毫米的 PDL 由两种类型的硅酮组成的 ATPBC 很好地模拟了 PDL。机械行为（1）力-位移关系、（2）应力松弛、（3）蠕变和（4）滞后通过已发表的结果得到验证。

结论

ATPBC 很好地模拟了生物研究报告的牙冠位移行为。
