“…It was fabricated as a flexible semirigid fixation system to medicate a wide range of maxillofacial fractures caused in the Vietnamese War. The procedure has since been improved and is now frequently used for a wide variety of maxillofacial surgeries (6,7). As it is biologically compatible, malleable, high in strength, low weight, widely available, minute inflammatory reaction, and imaging artifact, titanium is the perfect material for maxillofacial reconstruction (8,9).…”

BACKGROUND:One of the most frequent facial fractures is an orbital fracture, and multiple wall restoration is frequently required following high-energy trauma. Correct planning, thorough surgical dissection, and appropriate selection of the kind, size, and shape of the reconstruction material are all necessary for a successful outcome. The appropriate material to use to restore the orbital floor and walls is still up for debate. For that aim, numerous materials have been described from various sources. The ultimate goals involve treating the bony orbital deficiency while restoring anatomy, volume, function, and esthetics. While each type of material has benefits and drawbacks, the ability to fulfill those. AIM OF THE STUDY:This study evaluated the difference in the bone density after orbital floor fracture reconstruction with titanium mesh coated with natural nanohydroxyapatite by electrophoretic deposition versus conventional titanium mesh. PATIENTS & METHODS:This study was carried out clinically on 12 adult patients with fractures of the orbital floor that should be treated with internal fixation and open reduction. The patients were divided into 2 groups, (group A): patients where the reconstruction was done using coated titanium mesh with hydroxyapatite nanocrystals and (group B): the repair and reconstruction of the defect was using conventional titanium mesh. RESULTS: The radiographic differences in bone density between the study and control groups were statistically significant. CONCLUSION: The ongoing study displayed better bone density outcomes in reconstructed orbital floor defects with coated titanium mesh when compared to uncoated titanium mesh.

“…Miniplate osteosynthesis was first introduced by Michelet in 1973 and further developed by Champy et al , in 1975 and is the current standard for the treatment of mandibular fracture. [ 4 5 ] Champy et al , determined the ideal line of osteosynthesis on which plates must be applied to resist the torsional forces. [ 5 6 ] At present, modification in miniplates, like locking plates/screw system, has been developed.…”

Introduction: Fifty patients were included to compare the efficacy of three-dimensional (3D) locking miniplates versus 3D standard miniplates in the management of mandibular fractures. Materials and Methods: Fifty patients were randomly allocated to either 3D locking miniplate group or 3D standard miniplate group. All patients were followed for six months to compare post-operative occlusion, stability and associated clinical complications such as wound dehiscence, infection and plate/screw fracture and mental nerve paraesthesia. Results: All the fractures were adequately fixed when checked intraoperatively. Four patients in each group had mildly deranged occlusion, one patient in Group A and two patients in Group B had reduced stability. None of the patients had complications of non-union or malunion. In Group A, one out of 25 patients had mental nerve paraesthesia and two had wound dehiscence. Moreover, in Group B, two patients had mental nerve paraesthesia and two others had wound dehiscence. The data when compared were statistically significant (=0.05). Discussion: The overall result of our study led us to the conclusion that both the plating systems were satisfactory and there is no statistically significant difference when used for open reduction and fixation in mandibular fractures. Healing was satisfactory in both groups.

IntroductionThe use of two monocortical malleable 04‐hole miniplates, placed above and below the mental foramen, has been indicated to prevent the adverse effects of tension and torsion forces on fracture healing. To obtain good fixation in the mandible's outer cortex screws, 5–8 mm long have been recommended. However, studies have shown thicknesses in the mental foramen region of up to 3 mm, meaning the length of the screw could be a risk to nerve or tooth root damage. The purpose of this study is to identify the influence of screw length on osteosynthesis quality in the region of the mental foramen.Materials and Methods10 synthetic polyurethane human lower jaw replicas were subjected to a linear loading test to evaluate fixation techniques with 5 and 10 mm of displacement. In the photoelastic analysis, 02 lower jaw models were made of photoelastic resin and subjected to linear loading in the fixation technique with 10 mm of displacement. Two 04‐hole miniplates in the region of the mental foramen either fixed completely with 4 mm screws (group 1) or with 5 mm screws in the tension zone and 8 mm screws in the compression zone (group 2). The variables were registered for peak load and peak displacement, and final load and final displacement. One‐way analysis of variance (ANOVA) was applied, followed by the Tukey test, with a significance of 5% (p = 0.05) for the comparisons between the means.ResultsConsidering 95% confidence intervals, the mechanical test showed no statistical differences in peak load between the fixations groups. In the photoelastic analysis, the fringes were concentrated on the distal segment of the fracture in both groups.ConclusionDue to the lack of statistical difference in the biomechanical and photoelastic tests, considering the methodologic limitation, our study indicates a tendency of advantage toward the treatment of fractures with two 04‐hole plates, fixed with 4 mm screws, to minimize complications like tooth or nerve damage. In vivo studies are needed to verify the convergence of the results of in vitro studies to evaluate the resistance and stability in real masticatory forces.
