BACKGROUND In an attempt to contain the high cost of commercially available pedicle screw systems, several authors have used unconventional alternatives such as locally made plates or dynamic compression plates (DCP) along with cancellous screws for transpedicular fixation of the thoracolumbar spine. These plates, however, allow for a wide range of motion at the plate-screw interphase and the c...

BACKGROUND The current surgical therapy of midfacial fractures involves internal fixation in which bone fragments are fixed in their anatomical positions with osteosynthesis plates and corresponding screws until bone healing is complete. This often causes new fractures to fragile bones while drilling pilot holes or trying to insert screws. The adhesive fixation of osteosynthesis plates using PM...

INTRODUCTION It is important to understand the drivers leading to adaptive phenotypic diversity within and among species. The threespine stickleback (Gasterosteus aculeatus) has become a model system for investigating the genetic and phenotypic responses during repeated colonization of fresh waters from the original marine habitat. During the freshwater colonization process there has been a rec...

The loss of the buccal alveolar plate following tooth extraction in the maxillary anterior region is an especially challenging condition for the clinician. Immediate implant placement with a flapless approach has been suggested in order to reduce postextraction bone loss. In the presence of a significant vertical gap in the buccal plate after tooth extraction, most authors still recommend a bon...

Anaplastology ISSN: 2161-1173 Anaplastology, an open access journal Volume 2 • Issue 5 • 1000121 Today 3DM and RP techniques are widely employed to support planning in different types of surgery especially involving mandible malformation or defects such as bilateral sagittal split osteotomies [5] or chin repositioning by pre-bending titanium plates on the printed model [6]. RP models have also ...

OBJECTIVES We aimed to further evaluate the biomechanical characteristics of two locking screws versus three standard bicortical screws in synthetic models of normal and osteoporotic bone. METHODS Synthetic tubular bone models representing normal bone density and osteoporotic bone density were used. Artificial fracture gaps of 1 cm were created in each specimen before fixation with one of two...

The stiffness of articular cartilage increases dramatically with increasing rate of loading, and it has been hypothesized that increasing the stiffness of the subchondral bone may result in damaging stresses being generated in the articular cartilage. Despite the interdependence of these tissues in a joint, little is understood of the effect of such changes in one tissue on stresses generated i...

This paper deals with the development of a medical support model that can be used as prototype to study anatomy femur and for biomechanical research experimentation related bone plates. CT scan data are converted into 3D using MIMICS software imported finite-element analysis. The materials selected fabrication were PEEK CF (infused chopped carbon fibre). was analysed ANSYS® WORKBENCH® 2021 R2 d...
