“…This fracture confirmation may be a contributing factor to the relatively low strengths of the testing groups relying solely on the bone adhesive, or with other repair constructs that rely on the bone adhesive. Oblique fracture configurations may provide greater surface area for effective adhesion, but the shear forces acting upon unfavorable fractures may compromise this surface area advantage (42). Considering the high number of fractures through the mandibular first molar tooth (43), this testing model highlights possibly the most limited benefit of using bone adhesive for fracture fixation.…”

Mandibular fracture repair is complicated by limited availability of bone as well as the presence of the neurovascular bundle and an abundance of tooth roots. Fractures at the location of the mandibular first molar teeth are common and it can be particularly challenging to apply stable fixation. Non-invasive fracture repair techniques utilize intraoral placement of fixation devices typically involving polymerized composites and/or interdental wiring. A novel calcium phosphate-phosphoserine-based mineral-organic adhesive was tested ex vivo to determine its effects on augmenting strength of different non-invasive fracture fixation techniques. This study both tested the use of mineral-organic adhesive for the purpose of stabilizing currently used noninvasive fracture repair constructs (intraoral composite splinting ± interdental wiring) and evaluated adhesive alone or with subperiosteally placed plates on buccal cortical bone surface. Aside from controls, not receiving an osteotomy along the mesial root of the mandibular first molar tooth, six treatment groups were tested to evaluate ultimate strength, stiffness, angular displacement, bending moment, and application time. All forms of fixation were found to be significantly weaker than control (p < 0.001). Only the control (p < 0.001) and mineral-organic adhesive and composite (P = 0.002) groups were found to be significantly stronger than wire and composite. No difference was noted in stiffness between any groups with control or wire and composite. Application times varied from the mineral-organic adhesive group (mean = 206 s) to mineral-organic adhesive and composite (mean = 1,281 s). Twenty-three fixation devices exhibited adhesive failure, 20 demonstrated cohesive failure, and 5 failed by cohesive and adhesive failure. When evaluating the ultimate strength of the fixation device groups, mineral-organic adhesive, and composite was shown to be the strongest construct. The use of resorbable bone adhesive and composite may provide a stronger fixation construct over interdental wire and composite for mandibular fracture repair in dogs.

“…Depending of the fracture type or the size of the affected or missing part of the bone, for its proper rebuilding, plate implants and/or scaffolds can be used. In general, plates can be divided into two general groups: Locking plates and Non-locking plates [7][8][9][10]. Locking plates provide better stability of the bone-plate assembly and does not require pre-contouring of the plates.…”

The greatest challenge in engineering of human mandible implants lies in its customization for each patient individually, by adapting them to the patient's anatomical, morphological and physiological characteristics. This customization maximizes the efficiency of the patient's health recovery process. The application of anatomically shaped and personalized bone endoprosthesis, fixation plate and scaffold models bring great improvement to the clinical practice in maxillofacial surgery. It ensures that implant meets the biomechanical and dentofacial aesthetic requirements and, ultimately, reduces complications during recovery. In order to create such implants, novel procedure based on personalized models of mandible and its parts, and also plates and scaffold implants is presented in this paper. Design procedures for the creation of the personalized models are based on the application of Method of Anatomical Features, which has been already applied for the creation of geometrical models of human bones. This procedure improves pre-surgical planning, enables better execution of surgical intervention, and as a consequence improves patient recovery processes.

“…There are multiple factors affecting the stability of the fixation system as regards the dimensions, numbers and position of the fixation systems, however the study of the effect of the shape of plate on fracture stability was little through the literature. [4] Also, there continuing biomechanical trials to simulate the biomechanics of the mandibular symphysis, recently three dimensional finite element analysis can be used to study the complex mandibular biomechainics. [5] So that, the aim of this study was to determine the effect of the shape of miniplate on stability of mandibular symphyseal fracture using finite element analysis.…”

Introduction: Finite element analysis is a new technology used for mechanical designing, and showing the behavior of the body when subjected to different loads as regards the resulted stresses and displacement. Aim: The aim of this research was to detect the effect of the miniplate shape on stability of the mandibular symphyseal fracture. Patients/Methods: Through this study two configurations of the miniplates were compared. The two miniplates are equal in length, width, thickness and of the same material, only they are different in shapes, one plate was straight and the other was L shaped, they are investigated using three dimensional finite element software. Results: There was no significant difference between straight and L shaped miniplate, however the L shaped miniplate was slightly superior to straight miniplate as regard plate stability. Conclusion: There is no significant difference between the different systems. The shape of miniplate may have a role in stability of mandibular fracture stability, the same plate shows different behavior when fixed at different positions double plate shows more stability than single one ,of the same shape finite element technology is helpful means for designing of different fixation systems.
