Porous Surfaces for Dental and Orthopedic Implants

 

The area consists of one project: porous surfaces for dental and orthopaedic
implants. Successful oral rehabilitation relies upon the achievement of
osseointegration to insure rapid and sustainable stability and functionality of the
implant as well as optimal soft tissue healing. These demands have been addressed by changing the surface of titanium dental implants from a machined surface to a 23 structured/rough surface with better healing properties. For example, the TiUnite® implants commercialized by Nobel Biocare have an oxidized porous surface that facilitates the integration of the implants compared to implants with machined surface by enhancing bone formation. To further guide and optimize the healing process, the implant surface can be coated with active substances. Such coatings can reduce inflammatory reactions leading to bone resorption, stimulate bone formation for faster osseointegration, and/or local treatment of infections. A crucial prerequisite to develop implants with enhanced performance is the methodology for quantitative analysis of the osseointegration and healing processes at the implant/tissue interface
and their relation to microstructure and local chemistry.


The aim of the project is to establish materials processing principles and methods for producing a new generation of porous coatings on bioactive dental titanium and ceramics implants through understanding the roles porous surfaces play in enhancing early healing and tissue integration.
