Development and manufacture of bioceramic powders for use in nerve regeneration
|Funding from Vinnova||SEK 2 000 000|
|Project duration||October 2014 - December 2017|
Purpose and goal
The aim of the project has been to develop a stable process for the preparation of calcium sulfate hemihydrate of clinical quality for the production of biodegradable implants, for treatment of complete spinal cord injury. During the implementation of the project, two primary methods have been evaluated for material production and a promising process for manufacturing has been developed. The specification for material and final implant is high, and some process optimization remains.
Expected results and effects
The results of the project have been buildup up knowledge around calcium sulfate and processes for phase transformation into castable materials for clinical use. A promising manufacturing method has been developed and critical parameters for material properties have been identified and optimized. Expected effects of the project are further development of the manufacturing process to achieve the full material specification, followed by process verification and validation.
Planned approach and implementation
The project arrangement was ambitious but well established with the various project partners. The major challenge of the project has been the development of a process for producing materials with very specific characteristics. Process development in the project claimed more resources than planned, and since subsequent development required pre-developed materials, not all original work packages could be carried out. Unfortunately, all available skills in the project could thus not been fully utilized.
