Evaluation of the three methods of bacterial decontamination on implants with three different surfaces

Abstract

Background. The main goal of the treatment of the peri-implantitis is to decontaminate the surface of the implant, thereby enabling further treatment involving, e.g., guided bone regeneration. Since new implants of the rougher surface were introduced to the common dental practice, decontamination is even more difficult. Objectives. The aim of the study was to evaluate 3 different methods of decontaminating implants with 3 different surfaces. Material and methods. A total of 30 dental implants with 3 different surface types (machined, sandblasted, and acid-etched (SLA) and hydroxyapatite (HA)-coated) were used in the study. Each group of implants was coated with Escherichia coli biofilm and cultivated. Afterwards, the implants were transferred to the jaw model and treated with a different method: sonic scaler mechanical debridement with a Woodpecker PT5 sonic scaler (1 st group), and mechanical debridement with sonic scaler and with the combination with chemical agent Perisolv ® (2 nd group), and with Er:YAG laser treatment (3 rd group). Each implant was treated with the specific method and sent for further microbiological evaluation. Results. The highest level of decontamination was achieved for machined-surface implants and the lowest for HA-coated implants. The method with the highest biofilm reduction was the scaler and Perisolv ® group. The highest level of decontamination of HA-coated implants were achieved for Er:YAG laser irradiation method. Conclusions. In the following paper, the superiority of combined chemical-mechanical method of decontaminating the surface of the implant on SLA and machined-surface implants was proved. On the contrary, Er:YAG laser irradiation was reported as the best option for decontamination of the HA-coated implants. In our opinion, it is a significant finding, revealing that the method of peri-implantitis management should be considered in accordance to the type of the surface of the implant (customized to the surface of the implant).

An Experimental Anodized Titanium Surface for Transgingival Dental Implant Elements—Preliminary Report

“…Therefore, minimally invasive procedures have been introduced to increase patient post-surgical comfort by atraumatic acts [ 22 , 23 ]. Consequently, many new surgical and nonsurgical treatment methods for peri-implantitis management have been described; some demonstrated statistically significant clinical improvements, although the impacts on microbiological and biochemical parameters are still insufficient [ 24 , 25 , 26 , 27 ]. Therefore, primary prophylaxis of peri-implant diseases is important and can be achieved with correct treatment planning in terms of implant position, the morphologies of soft tissues surrounding the implant, and the proper prosthetic reconstruction [ 28 , 29 , 30 , 31 ].…”

Photodynamic Therapy (PDT) in Prosthodontics: Disinfection of Human Teeth Exposed to Streptococcus mutans and the Effect on the Adhesion of Full Ceramic Veneers, Crowns, and Inlays: An In Vitro Study

“…Using tissue regeneration laser settings, as well as the addition of methylene blue as a photosensitizer and its washing with Kaqun water, represents an atypical protocol of PDT. Other studies have shown the effectiveness of various standard PDT protocols on both aerobic and anaerobic bacterial species [ 27 , 28 , 29 , 30 ]. The selection of the photosensitizer (MB) and laser power (100 mW) was based on previous works that demonstrated their efficacy [ 4 , 21 , 30 ].…”

Effects of an amino acid buffered hypochlorite solution as an adjunctive to air-powder abrasion in open-flap surface decontamination of implants failed for peri-implantitis: an ex vivo randomized clinical trial

“…The effect of an amino acid buffered hypochlorite solution on implant surface decontamination was also evaluated in vitro by Kubasiewicz-Ross et coll. [ 21 ]. In this study, 30 implants with different surfaces (machined, sandblasted and acid-etched, hydroxyapatite-coated) were coated with Escherichia coli biofilm, cultivated, and transferred in peri-implantitis jaw models with a 6-mm artificial bone defect.…”
