The development of the tissue-implant interface is a complex series of cascades of cellular activity that are preceded by both ionic exchange events and protein adsorption. In this presentation, the early wound healing events in bone between day 0 and 8 weeks will be shown as well as the impact of surface chemistry and texture modifications on both maintenance of the primary stability and the alveolar bone crest level. Furthermore, an overview of the multiple factors influencing the outcome of the peri-implant soft tissue integration will be provided. Detailed research data of the junctional epithelium, as well as the connective tissue interface to abutments and implants, will be compared for machined and various surface modifications. In addition, recent research data about the structure and ultrastructure of the soft tissue interface to zirconium dioxide abutments will be demonstrated. The presentation will conclude with an evaluation of the risk for peri-implantitis posed by a rough or otherwise modified implant surface.
