3D CAD/reverse engineering technique for assessment of Thai morphology: Proximal femur and acetabulum.

Purpose: To assess morphological parameters of proximal femur and acetabulum in Thai population with three-dimensional measurement technique, and to analysis of collateral side symmetric, gender difference, and correlation between morphometric parameters.

Methods: Investigation was performed in 240 femurs. All three-dimensional femur models were acquitted from 64-slice spiral CT scanner.

Biocompatibility of hydroxyapatite scaffolds processed by lithography-based additive manufacturing.

The fabrication of hydroxyapatite scaffolds for bone tissue engineering applications by using lithography-based additive manufacturing techniques has been introduced due to the abilities to control porous structures with suitable resolutions. In this research, the use of hydroxyapatite cellular structures, which are processed by lithography-based additive manufacturing machine, as a bone tissue engineering scaffold was investigated. The utilization of digital light processing system for additive manufacturing machine in laboratory scale was performed in order to fabricate the hydroxyapatite scaffold, of which biocompatibilities were eventually evaluated by direct contact and cell-culturing tests.
