“…Several studies came to the same conclusion that anodized titanium surfaces exhibited lower bacterial biofilm mass than untreated titanium surfaces [9,18,55] and machined titanium had a lower bacterial biofilm than other types of implant materials (e.g. zirconia, copper) [1,12,29]. Polished titanium surfaces had lower bacterial biofilm than untreated titanium with rougher surfaces [4,6,26,40,49,52].…”

“…Also, the different surface topographies did not significantly influence the colonizing microbiota [14]. In another investigation, the smoothing of a surface (polishing) did not reduce the ability of bacteria to adhere to metallic surfaces [29]. This is because smooth surfaces were still capable of attracting substantial levels of specific bacteria.…”

The effect of different surface topographies of titanium implants on bacterial biofilm: a systematic review

To compare the different surface topographies of titanium implants used in dentistry against the formation of bacterial biofilm. To identify relevant studies, the electronic databases PubMed, Science Direct and Springer Link were searched from inception until January 2019. A total of 38 studies were selected for the systematic review (n = 38). The most commonly used titanium surfaces were machined titanium (16.3%), sandblasted, large-grit, acid-etched titanium (10.9%), untreated or pure titanium (10.9%), polished titanium (9.8%), physically textured titanium (9.8%), acid-etched titanium (8.7%) and anodized titanium (5.4%). The majority of the studies (78.9%) found that surface topographies (with varying degrees of roughness) had a beneficial effect on the ability to allow low bacterial biofilm on the surfaces. A low roughness value (R a) of below 1 µm was found in 68% of these surfaces. Overall, no specific surface topography was found to be the ideal surface in allowing the least bacterial biofilm attachment. In this study, meta-analysis was not performed. This narrative systematic review provides a summary of the effects of surface topographies for future research and development of new dental implant surfaces and decontamination techniques.

Материалы, используемые для изготовления дентальных имплантатов, должны обладать механической прочностью, высокой биосовместимостью, отсутствием биодеградации и в основном должны решать две задачи: улучшение интеграции инородных тел с живыми тканями организма и борьбу с периимплантной инфекцией. Обе неурегулированные проблемы могут стать причиной отторжения искусственных изделий. Для выявления современного положения дел по выбору материалов для изготовления дентальных имплантатов и приданию им антибактериальных свойств была изучена научная литература за последние 2 года. Принимая во внимание большое число разноречивых результатов исследований, посвященных каждой из проблем дентальной имплантации, можно сделать заключение, что ни одна из основных задач окончательно не решена. Продолжаются поиски материалов, которые взаимодействуют с биологическими тканями без развития сопутствующего воспалительного процесса. Также не закончены разработки методов, направленных на профилактику и борьбу с периимплантной инфекцией. Формирование костной ткани на границе имплантата, срастание его поверхности с костью, несомненно, является благоприятным признаком, свидетельствующим о стабильности установки изделия, долгосрочности его службы. Необходима тщательная обработка поверхности имплантатов для исключения попадания в ткани даже мельчайших его частиц, что может поставить под сомнение успешность самой процедуры дентальной имплантации. Целесообразно изготавливать все детали имплантата из одного материала для профилактики электрохимической коррозии изделий в тканях на границе различных металлов. Перспективно нанесение покрытия на дентальные имплантаты, которое не только обладает антимикробным свойством, но и улучшает процессы их остеоинтеграции. Также представляется эффективной активная или пассивная адсорбция бактериофага или смеси нескольких бактериофагов на поверхности имплантируемых материалов. Необходимо отметить, что качество изделий, внедряемых в организм, постоянно улучшается, постепенно совершенствуются их различные характеристики, что способствует повышению эффективности ближайших и отдаленных результатов хирургического вмешательства-дентальной имплантации. Ключевые слова: обзор литературы, дентальная имплантация, имплантируемые материалы, взаимодействие искусственных материалов с тканями организма, антибактериальные свойства имплантатов.

“…Therefore, infection-free establishment of bone-implant integration has become a persistent challenge in oral rehabilitation. Various efforts have been made to enhance the anti-bacteria ability of dental implants to resist peri-implant diseases [ 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. Dimethylaminododecyl methacrylate (DMADDM), a novel quaternary ammonium salts (QAS), is known as a long-lasting and remarkable antibacterial additive with good biocompatibility, which had been incorporated into different dental materials [ 18 , 19 , 20 , 21 , 22 ].…”

The effects of dimethylaminododecyl methacrylate (DMADDM) modified titanium implants on bacterial activity and microbial ecosystem of saliva-derived biofilm were investigated for the first time. Titanium discs were coated with DMADDM solutions at mass fractions of 0 mg/mL (control), 1, 5 and 10 mg/mL, respectively. Biomass accumulation and metabolic activity of biofilms were tested using crystal violet assay and MTT (3-(4,5-Dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. 16S rRNA gene sequencing was performed to measure the microbial community. Live/dead staining and scanning electron microscopy (SEM) were used to value the structure of biofilm. The results showed that the higher mass fraction of DMADDM the coating solution had, the significantly lower the values of metabolic activity and accumulated biofilms got, as well as fewer live cells and less extracellular matrix. Moreover, 5 mg/mL of DMADDM was the most effective concentration, as well as 10 mg/mL. In microecosystem-regulation, the DMADDM modified titanium implant decreased the relative abundance of Neisseria and Actinomyces and increased the relative abundance of Lactobacillus, a probiotic for peri-implant diseases. In conclusion, via inhibiting growth and regulating microecosystem of biofilm, this novel titanium implant coating with DMADDM was promising in preventing peri-implant disease in an ‘ecological manner’.

An assessment of early colonisation of implant-abutment metal surfaces by single species and co-cultured bacterial periodontal pathogens

Abstract: Both surfaces studied may be used at implant-abutment junctions and both possess an ability to establish a bacterial biofilm containing a periodontally-relevant species. These surfaces are thus able to facilitate the apical migration of bacteria associated with peri-implantitis.
