Abstract
The adherence of dental plaque to a dental implant plays an important role in the inflammation around a dental implant. It is known that silver ions have antibacterial activity and low toxicity. Therefore, we examined the antibacterial activity of dental implant material (IMZ implant) gotten or not by ion implantation and arc-plasmas coating. Under anesthesia, the tested materials were implanted into submaxillary of 6 beagle dogs. The dogs were given softened food, without carrying out brushing, for 2 weeks after inserting abutments. Oral photographs were taken after 2 weeks. There was an obviously difference in plaque adherence between the abutment with and without silver coating. These results indicate that the anti-plaque effect found in this study was due to the silver ions released by silver coated abutment of dental implants, and that it may be useful for protection against inflammation around a dental implant.
