An implant abutment should be soft tissue-compatible and resistant to plaque accumulation. So could different methods of cleaning and sterilizing abutments trigger greater degrees of human gingival fibroblast (HGF) attachment? A recent study 1 about exposure of dental abutments to cleaning by Radio Frequency Glow Discharge Treatment (RFGDT) suggests that is the case.
The study concluded:
This work confirmed and extended observations of prior studies that RFGDT materials have mitogenic effects that might be captured for stimulating desired tissue growth around implanted biomaterial appliances.
Earlier research2 also seems to support this conclusion. In that study the researchers, cleaned temporary abutments for three techniques of increasing rigor, (ultrasonic treatment in distilled water; ultrasonic treatment in propanol; and Radiofrequency Glow Discharge Treatment (RFGDT)), and concluded that:
It is clear from the sum of these findings that application of the additional cleaning step of RFGDT to resin composite and acrylic temporary abutments can be beneficial to the growth and attachment of contacting human gingival fibroblasts.
