Bio-scaffold International (BSI) is continuing its effort in R&D of the process methodology of scaffold to tailor the properties for new applications that are non-load bearing tissues as well as expand the application of current scaffold beyond non-load bearing soft tissues. BSI is hoping to develop new synthetic material bone substitutes, properties of which can be matched to bone properties to aid easy integration as well as shorten the healing time. Another application currently being explored is to enhance current scaffolds with additional features to extend the applications beyond the current one. BSI is also working towards delivering a scaffold for segmental repair and augmentation by controlling the process parameters to have good dimensional control and controlled degradation. Currently, scaffolds for hard tissue are either made using solid metals and ceramics ! especially for elderly patients where self healing is difficult. However, one of the limitation is the difference in mechanical properties between the hard tissue and that of the permanent scaffold, i.e., Cortical bone has a modulus of 7 - 30 GPa while most commonly used implants (permanent scaffolds) have modulus that are typically 4 to 5 times the bone modulus leading to complications such as stress shielding. BSI is also aiming at developing a porous implant (permanent scaffold) with tailored mechanical properties using the biomaterials currently used to overcome this limitation.
