Abstract
Objectives
-
1.
To evaluate the efficacy of two plating system in comparison with single plating system
-
2.
To 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.
