The creation of a three-dimensional finite element model of palatal implant anchorage

Objective To creating A three-dimensional finite element model of palatal implant anchorage for the further investigation on the biomechanics around palatal implant to enhance molars anchorage. Methods Spiral CT scanning, image processing and CAD technology and FEM software were employed in the study to construct the three-dimensional finite element model of maxilla with a palatal implant. Results A three-dimensional finite element model of palatal implant anchorage is successfully constructed, meeting the needs of biomechanical study. Conclusion It was suggested that spiral CT scanning, image digital processing and CAD technology could provided a method to create three-dimensional finite element model accurately and reliably. This model supplies apply a base for the study on biomechanics of maxilla implant.
