From the consolidation of surface treatments of dental implants and knowledge of the cellular mechanisms of osseointegration, studies have highlighted the importance of sealing connective tissue and implant, in order to avoid contaminants from the oral environment and biofilm installation. The lecture promotes a contemporary discussion about the use of dental prosthetic components with or without surface treatment. Based on scientific evidence and our in vitro study, we evaluated whether different titanium surface treatments promoted by acids at different times promote increased secretion, proliferation and viability of collagen fibroblast cells.
