Biomechanical Optimization of Bone Plates Used in Rigid Fixation of Mandibular Fractures

Minimally Invasive Bioabsorbable Bone Plates for Rigid Internal Fixation of Mandible Fractures

“…This is the same value and same model as a previous study by our group. 4 Furthermore, P(L/DL)LA can be manufactured with a tensile yield stress of up to 359 MPa. 12 These 2 values were set as the state variable maxima for the optimization analysis.…”

“…Lovald et al 4 previously gave a full discussion of material property assumptions. In the present simplified model, the modulus of elasticity for bone is defined as E=20 000, and the Poisson ratio is defined as =0.3.…”

In vitro mechanical assessment of 2.0-mm system three-dimensional miniplates in anterior mandibular fractures

“…Furthermore, studies using 3D models have shown that the areas of tension and compression are not fixed but are liable to alternate with one another. 6,18,[26][27][28] Other studies evaluating the use of RIF have applied the forces to the region of the central incisors, 29,30 which offers only a very small area of contact, making it difficult to accommodate the testing device and increasing the likelihood of its slipping from the point of contact and altering the results. 19 Our study took heed of the various recommendations made by Tams et al 25 , who determined the most effective positioning of the plates, and took particular care in the case of the superior border to respect the anatomical limits of the tooth root apices.…”

Capturing the multiscale anatomical shape variability with polyaffine transformation trees

“…In Lovald et al (2009), it was shown that implants optimized for the "body" region, (Fig. 1), have fracture strain of 69% to 59% and implant stress of 34% to 27% with respect to smaller standard implants, while minimizing patient intrusion by saving 55% of implanted volume of larger standard implants.…”

“…gender, age, etc.). None of the aforementioned population-based approach consider the bone mineral density in addition to the surface geometry, even though Lovald et al (2009Lovald et al ( , 2010 reported its importance to achieve optimal design and placement of screws.…”
