“…All of the individuals displayed a normal inter-cuspal centric occlusal connection regarding the postoperative occlusion, necessitating neither elastic tension nor any type of selective grinding or extraction. The similar conclusion was reached by other authors [27,28] . But according to Kotrashetti and Singh's (2017), there were 26.7% (n=2) of postoperative malocclusion cases that needed elastic traction for 15 days in order to reestablish their premorbid occlusion [29] .…”

Objective:The purpose of this study was to to present maximum voluntary bite force as a reliable objective assessment tool for the analysis of the management of mandibular fracture. Materials and methods:The study is a prospective case series for evaluation of the postoperative bite force in patients suffering from mandibular fracture posterior to the mental foramen and managed with open reduction and internal fixation. Statistical significance was set at the 5% level. Results: Twelve patients were enrolled in this study. Nine of the involved patients suffered from a mandibular angle fracture, while three patients complained from mandibular body fracture. All patients across the follow-up sessions reported a statistically significant decrease in the level of the experienced pain intensity. All of the operated patients reported a statistically significant increase in the level of the measured inter-incisal mouth opening. Across the examination period, the mean reported maximum voluntary bite force showed a statistically significant increase. Conclusion:Postoperative maximum voluntary bite force analysis is a a reliable objective tool for the assessment of the quality of posterior mandibular fracture management, outlining the favourable outcome of open reduction and internal fixation.

Mandibular fractures are very common in maxillofacial trauma surgery. While previous studies have focused on possible risk factors related to post-operative complications, none have tried to identify pre-existing conditions that may increase the risk of mandibular fractures. We hypothesized, through clinical observation, that anatomical conditions involving poor dental contacts, such as malocclusions, may increase the risk of mandibular fractures. This work was subdivided into two parts. In the first part, Digital Imaging and Communications in Medicine (DICOM) data of four healthy patients characterized by different dentoskeletal occlusions (class I, class II, class III, and anterior open bite) have been used to develop four finite element models (FEMs) that accurately reproduce human bone structure. A vertical and lateral impact have been simulated at increasing speed on each model, analyzing the force distribution within the mandibular bone. Both vertical and lateral impact showed higher level of stress at the impact point and in the condylar area in models characterized by malocclusion. Specifically, the class III and the open bite models, at the same speed of impact, had higher values for a longer period, reaching critical stress levels that are correlated with mandibular fracture, while normal occlusion seems to be a protective condition. In the second part of this study, the engineering results were validated through the comparison with a sample of patients previously treated for mandibular fracture. Data from 223 mandibular fractures, due to low-energy injuries, were retrospectively collected to evaluate a possible correlation between pre-existing malocclusion and fracture patterns, considering grade of displacement, numbers of foci, and associated CFI score. Patients were classified, according to their occlusion, into Class I, Class II, Class III, and anterior open bite or poor occlusal contact (POC). Class I patients showed lower frequencies of fracture than class II, III, and open bite or POC patients. Class I was associated with displaced fractures in 16.1% of cases, class II in 47.1%, class III in 48.8% and open bite/POC in 65.2% of cases (p-value < 0.0001). In class I patients we observed a single non-displaced fracture in 51.6% of cases, compared to 12.9% of Class II, 19.5% of Class III and 22.7% of the open bite/POC group. Our analysis shows that class I appears to better dissipate forces applied on the mandible in low-energy injuries. A higher number of dental contacts showed a lower rate of multifocal and displaced fractures, mitigating the effect of direct forces onto the bone. The correlation between clinical data and virtual simulation on FEM models seems to point out that virtual simulation successfully predicts fracture patterns and risk of association with different type of occlusion. Better knowledge of biomechanics and force dissipation on the human body may lead to the development of more effective safety devices, and help select patients to plan medical, orthodontic/dental, and/or surgical intervention to prevent injuries.
