Evaluation of Mechanical Resistance After Fixation of Mandibular Condylar Fracture with Single and Double Miniplates: A Comparative In Vitro Study

Objectives To evaluate the efficacy of two plating system in comparison with single plating system 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
