3D printing of topographic features on dental implant surfaces to promote osseointegration

The long-term success of any implant is closely dependent on the interrelationship of various parameters,including biocompatibility of the bulk material, macroscopic and microscopic features of the implant surface,the status of the implant bed (host bone quality and quantity) and the surgical technique per se. In the case ofdental implants, the biological interactions take largely place at the interface between the bone tissue and thematerial. Consequently, the surface properties of implants play a crucial role in predicting their clinical success.In this context, the surface modification approach has recently gained an important and decisive place inbiomaterials research, as tool to control the rate and quality of implant osseointegration. The current projectseeks to create well-defined topographies on the surface of conventional materials used in oral implantologybecause there is growing evidence suggesting that bone cells perceive and respond to topographical cues.Therefore, our objective is to determine topographical features that facilitate early osseointegration and ensurelong-term bone-implant anchorage.
