“…The rate of incidence seems to be low, but it leads to overwhelming outcomes such as malunion, non-union, paresthesia, osteomyelitis and prolonged functional and nutritional disturbances [3]. On the other hand, the mandible is the most common broken bone by cause of facial injuries with the ratio of 23–97% [4]. The insertion of implants to the weakend mandibular bone decreases the strength of the bone and may lead to fractures either during or after implant placement [5].…”

BackgroundRehabilitation using an implant supported overdenture with two implants inserted in the interforaminal region is the easiest and currently accepted treatment modality to increase prosthetic stabilization and patient satisfaction in edentulous patients. The insertion of implants to the weakend mandibular bone decreases the strength of the bone and may lead to fractures either during or after implant placement. The aim of this three dimensional finite element analysis (3D FEA) study was to evaluate the biomechanical effects of implant diameter in case of facial trauma (2000 N) to an edentulous atrophic mandible with two implant supported overdenture.MethodsThree 3D FEA models were simulated; Model 1 (M1) is edentulous atrophic mandible, Model 2 (M2), 3.5x11.5 mm implants were inserted into lateral incisors area of same edentulous atrophic mandible, Model 3 (M3), 4.3x11.5 mm implants were inserted into lateral incisors area of same edentulous atrophic mandible.ResultsIn M1 and M2 highest stress levels were observed in condylar neck, whereas highest stress values in M3 were calculated in symphyseal area.ConclusionsTo reduce the risk of bone fracture and to preserve biomechanical behavior of the atrophic mandible from frontal traumatic loads, implants should be inserted monocortically into spongious bone of lateral incisors area.

Introduction: Mandibular angle fracture (MAF) is the second most common site of all fractures of the mandible with the highest complication rate. Management of MAF has evolved in the past four decades. The purpose of the prospective study was to compare the efficacy of new design titanium miniplate (NDM) with conventional titanium miniplate (CTM) in the treatment of MAF. Objectives: Mouth opening, occlusion, bite force measurement, and radiographs compared preoperatively and first week, first month and third month postoperatively. Materials and Method: Fourteen patients diagnosed with MAF were randomly divided into two groups: Group A (seven patients) was treated with NDM and Group B (seven patients) with CTM. Patients were assessed preoperatively and postoperatively at an interval of one week, one month and three months. Results: Repeated measures ANOVA and Post hoc Tukey test showed a significant increase in bite force and mouth opening for both groups in first and third postoperative months. Unpaired t-test showed slightly better mouth opening in Group B and slightly higher bite force in Group A. Discussion: Both miniplates fulfilled all the study objectives and equally satisfactory healing was seen at the end of third month. NDM offers better stability, rigidity, and anatomic reduction of the fracture with a drawback of difficulty in adaptation and increased operative timing compared to CTM. Hence, we would like to conclude that both miniplates are equally efficient in the treatment of non-comminuted angle fractures with the NDM having upper hand in stability.

The aim of this study was to assess fracture stability and postoperative complications in patients with isolated mandibular angle fractures after open reduction and fixation with external oblique ridge six-hole non-compression Suer K miniplate compared to lateral border conventional six-hole non-compression titanium straight miniplate. The study was conducted on 24 patients divided randomly into two equal groups according to the used plates. Intraoperative time was measured, occlusion and edema were assessed in both groups. Postoperative CT was performed immediately and after 3 months. Intraoperative was longer for the study group (43.6 ± 8.7 minutes) compared to the control group (36.3 ± 11.2 minutes), with no statistical significance difference between the two groups (P-value 0.09). Regarding occlusion and edema, the study group showed slightly better results after 1 week and 1 month, with no statistical significance difference between the two groups (P-value 0.59, 0.478, 0.53, 0.53, respectively). Interramal distance change showed highly stable and comparable results (0.067 ± 0.063 mm control, 0.073 ± 0.044 mm study) with no statistical significance difference between the groups (P-value 0.76). This study showed that Seur K plate is a safe and effective alternative to the single miniplate in treating non comminuted minimally displaced angle fractures.
