Abstract

OBJECTIVES

To evaluate the efficacy of two plating system in comparison with single plating systemTo study the biomechanical behaviour of single and two plating system when compression load is applied.

MATERIALS AND METHODS

Twenty hemimandibles were divided into two groups A and B of ten each. A subcondylar fracture was created. Group A was stabilized by single adaptation plating technique and group B by double adaptation plating technique and both the groups were tested for stability by using universal testing machine.

RESULTS

Higher mean displacement was observed in Group A compared to Group B, but the difference in mean displacement between the two groups was not statistically significant (p > 0.05). Higher mean load was recorded in group B compared to group A and the difference in mean load between them was found to be statistically significant (p < 0.001).

CONCLUSION

The present study demonstrated that double adaptation plating technique had greater resistance to compression load than single adaptation plating technique and it shows more favorable biomechanical behavior.

摘要

目的

评估两种接骨板系统与单接骨板系统相比的疗效。研究施加压缩载荷时单接骨板系统和双接骨板系统的生物力学行为。

材料与方法

将20个半下颌骨分为A、B两组，每组10个。制造髁突下骨折。A组采用单适配接骨板技术固定，B组采用双适配接骨板技术固定，两组均使用万能试验机测试稳定性。

结果

与B组相比，A组观察到更高的平均位移，但两组之间的平均位移差异无统计学意义（p>0.05）。与A组相比，B组记录到更高的平均载荷，且两者之间的平均载荷差异具有统计学意义（p<0.001）。

结论

本研究表明，双适配接骨板技术比单适配接骨板技术对压缩载荷具有更大的抵抗力，并且显示出更有利的生物力学行为。
