Effect of biofilm formation on implant abutments with an anti‐bacterial coating: A pre‐clinical in vivo study

Abstract

A new classification of peri-implant diseases was presented in a consensus report from the 2017 World Workshop on Classification on Periodontal and Peri-implant diseases and Conditions (Berglundh et al., 2018). Thus, peri-implant mucositis is an inflammatory lesion in the soft tissue surrounding a dental implant in the absence of loss of supporting bone, while peri-implantitis is characterized by inflammation in the peri-implant mucosa and subsequent progressive loss of peri-implant bone (

Antibacterial Effects of Modified Implant Abutment Surfaces for the Prevention of Peri-Implantitis—A Systematic Review

“…After reviewing the abstracts the number of eligible articles was reduced to 12. A final review resulted in the selection of nine articles [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. For the assessment of inter-reviewer agreement the k value was calculated and showed a value of k = 1.…”

“…Finally for the preclinical study of Almohandes et al, [ 18 ] selection bias was found to be low risk or not applicable, performance bias was found to be low risk or not applicable, detection bias was found not applicable, attrition bias, reporting and other bias were found to be low risk. Bias considerations found not applicable were due to the low number of animals and the study design, as all animals received test and control group samples.…”

“…Eight studies modified titanium and one study titanium zirconium samples. Furthermore, eight studies [ 10 , 11 , 12 , 13 , 14 , 15 , 17 , 18 ] evaluated the antibacterial properties of inorganic abutment coatings. Only one study [ 16 ] examined an organic coating.…”

“…Furthermore Almohandes et al, [ 18 ] performed a preclinical in-vivo study in dogs and showed that titanium-bismuth-gallium coating did not prevent biofilm formation on implant abutments 6 and 7.5 month after placing ligatures around the implant abutment for 4 weeks.…”

“…Therefore, preventing bacterial invasion already within implant surgery for example by applying antibacterial-coated cover screws might be helpful, however, they are not on the market yet. Coatings for both implants and abutments have already been developed but are not yet clinical routine [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. These surface modifications can be achieved through different surface treatments and allow a reproducible control of required surface properties on nearly every part of an implant [ 19 ].…”
