“…Berglundh et al 20 investigated SBAES in spontaneous progression of peri-implantitis in dogs and concluded that progression of peri-implantitis is more pronounced on rough surfaces than on smooth ones. In this context, Pongnarisorn et al 21 assessed the effects of different surface treatments on the transmucosal area of implants (machined, acid-etched, and anodized) and suggested that the development of implant-associated inflammation is not dependent upon the type of surface or roughness, but rather upon the presence of bacterial plaque.…”

Antiseptics and microcosm biofilm formation on titanium surfaces

Oral rehabilitation with osseointegrated implants is a way to restore esthetics and masticatory function in edentulous patients, but bacterial colonization around the implants may lead to mucositis or peri-implantitis and consequent implant loss. Peri-implantitis is the main complication of oral rehabilitation with dental implants and, therefore, it is necessary to take into account the potential effects of antiseptics such as chlorhexidine (CHX), chloramine T (CHT), triclosan (TRI), and essential oils (EO) on bacterial adhesion and on biofilm formation. To assess the action of these substances, we used the microcosm technique, in which the oral environment and periodontal conditions are simulated in vitro on titanium discs with different surface treatments (smooth surface -SS, acid-etched smooth surface -AESS, sand-blasted surface -SBS, and sand-blasted and acid-etched surface -SBAES). Roughness measurements yielded the following results: SS: 0.47 µm, AESS: 0.43 µm, SB: 0.79 µm, and SBAES: 0.72 µm. There was statistical difference only between SBS and AESS. There was no statistical difference among antiseptic treatments. However, EO and CHT showed lower bacterial counts compared with the saline solution treatment (control group). Thus, the current gold standard (CHX) did not outperform CHT and EO, which were efficient in reducing the biofilm biomass compared with saline solution.

“…It is not clear if the microbial composition of a biofilm is affected by the physicochemical properties and texture characteristics of the implant surface. Higher roughness and higher free energy of the implant surface may favour biofilm formation (35), whereas peri-implantitis may occur earlier, with a faster and more extensive progression in implants with rougher surface (36)(37)(38). Nevertheless, it is also shown that abutments with different surface characteristics can influence neither biofilm formation on the implant surface, nor the extent and cellular composition of the resulting inflammatory lesion (39).…”

“…The presence of microorganisms in the periimplant tissues may lead to a chronic inflammatory response causing implant failure. Periimplantitis can lead to implant loss in later stages (6,8,9) and a correlation between biofilm accumulation and progressive periimplant bone loss has been reported in experimental and clinical studies (6,7,10).…”

Preload loss and bacterial penetration on different implant-abutment connection systems

et al. 2010

Preload loss can favor the occurrence of implant-abutment interface misfit, and bacterial colonization at this interface may lead to implant failure. The aim of this study was to evaluate the preload loss and bacterial penetration through the implant-abutment interface of conical and external hexagon connection systems subjected to thermal cycling and mechanical fatigue (TM). Four different implant-abutment connection systems were evaluated (n=6): external hexagon with universal post, Morse taper with universal post, Morse taper with universal post through bolt, and locking taper with standard abutment. The assemblies (implant-abutment) were subjected to a thermal cycling regimen (1,000 cycles of 5°C and 55°C) and to mechanical fatigue (1.0 million cycles, 1.0 Hz, 120 N). The assemblies were immersed in Tryptic Soy + Yeast Extract broth containing Streptococcus sanguinis and incubated at 37°C and 10% CO 2 for 72 h. Detorque values were recorded. The bacterial penetration was assessed and the abutments were observed by scanning electron microscopy. The preload data were analyzed statistically by two-way ANOVA and Tukey's test at 5% significance level. All screw abutment systems showed significantly higher (p<0.05) detorque values when subjected to TM and all conical systems presented bacterial penetration. The results show no relationship between the preload loss and the bacterial penetration.

Spontaneous progression of ligature induced peri‐implantitis at implants with different surface roughness: an experimental study in dogs

Abstract: It is suggested that the progression of peri-implantitis, if left untreated, is more pronounced at implants with a moderately rough surface than at implants with a polished surface.
