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.
