Comparative Evaluation of Bite Forces in Patients with Mandibular Fractures Treated With Microplates and Miniplates.
Journal Title: International Journal of Dental Science and Innovative Research (IJDSIR) - Year 2019, Vol 2, Issue 2
Abstract
Aim: To compare bite forces generated in patients treated with miniplates and microplates in mandibular fractures at different postoperative interval and to compare the efficacy and functional stability of these plates in the treatment of isolated mandibular fractures. Materials & Methods: Twenty patients were selected with isolated mandibular fractures and divided into two groups with each of ten patients (study group I and II) and treated with miniplate and microplate osteosynthesis by open reduction and rigid internal fixation. Ten healthy young individuals were selected, as control, of different age group of either gender for recording the maximum voluntary bite forces. The bite forces of both the study groups was recorded pre operatively and post operatively at each follow up using bite force tranducer and compared with the control group. The patients were also assessed for complications such as infection and wound dehiscence that might interfere with the overall success of osteosynthesis. Observation and Results: A statistically significant increase in the bite force of incisors and right and left molar region was noticed in both the study groups compared with the pre operative bite forces. However, there was no statistically significant difference observed in the bite forces of both the study groups at different follow up period. There was a progressive increase in the bite forces as each follow up which suggested a satisfactory healing of the bone. Post operative infection was noticed in 1 patient (10%) in each of the study group which was eventually resolved by use of antibiotics. Conclusion: The use of microplate osteosynthesis is stable enough to withstand the masticatory forces generated during the healing phase of the fractured bone and can be effectively preferred in the place of miniplates for fixation of isolated mandibular fractures.
