Effectiveness of homecare and professional biofilm removal procedures on different materials and surfaces

Microbial biofilm in the vulnerable section of dental implants, the region of passing through the soft tissue, is the primary factor of the development of peri-implant infections. In this critical area implant materials as well as abutment materials are located. In the quest of new implant surfaces, showing slower and less biofilm formation on their surfaces different materials based on titanium, zirconium oxide, polyether ether ketone and pectin were evaluated regarding initial in vivo biofilm formation. Furthermore the influences of variances of surface structures / micro structures were investigated. Some surfaces showed significant better results regarding slower biofilm development. Another important aspect is the decontamination of these surfaces via domestic or professional procedures. The surfaces and modifications of surfaces, combining slow initial biofilm development and good cleanability will be demonstrated in the presentation.

Learning objectives

  • To understand which materials and surface modifications could reveal advantages regarding less initial biofilm formation
  • To obtain an overview on which implant or abutment material or modification of the surfaces glycine powder blasting as well as tooth brushing are most effective
  • To get prospects on candidates for new implant or abutment designs
