The pursuit for surfaces open of preventing bacterial colonisation and attachment just about alveolar implants is a field of study of search interest, according to Beatriz Palla, a investigator in the Biomaterials Radical of the UPV/EHU’s Section of Polymer Science and Technology. Approximately 10 percent of implants deliver to be removed owed to osseointegration problems or to the onslaught of infections.
Project challenges let in providing the aerofoil of titanium implants with antibacterial drug properties patch considering the impedance that microorganism strains are capable of development to conventional therapies with antibiotics. That was the gainsay that the UPV/EHU aggroup was not bad to harness. “We had already obtained coatings that facilitate the generation of bone around the implant and thus facilitate anchoring to the bone. To go a step further, we looked at how to turn these coatings into bactericides,” said the investigator.
The method they ill-used was sol-colloidal gel synthetic thinking. Sol-gelatin deductive reasoning is founded on the provision of a precursor solution (sol) that, when left wing on its ain for a while, turns into a gelatin that give notice be victimized to coat the aerofoil of the atomic number 22 screw, and after heat discussion at a high school temperature in the kiln, becomes adhered to the jailor that wish be deep-rooted. “We used silica as the precursor, because in many studies, this compound has been shown to be osteoinductive, thus facilitating one of the objectives we sought. Additionally, to provide the materials with antibacterial characteristics, we added various antibacterial agents.”
In the study, Palla developed ternary types of coatings depending on the versatile bactericide agents chosen; each unmatchable had a mechanism to take on bacterial infections, either prophylactically by preventing the bacteria from at the start decorous adhered; by addressing the subsequent infection; or else by eliminating it one time developed.
What was needful in the character of rubber coatings was “a material with a very long degradation time so that it would remain adhered to the screw and work for as long as possible, preventing bacteria from becoming adhered,” said Palla. In the coatings studied to root diş implantları out an contagion that has already interpreted hold, however, “a rapidly degrading material is needed so that it can release the antibacterial agent as quickly as possible to attack the infection.” Furthermore, unmatched of the coatings highly-developed for this intent “is designed to be used in situ, during the surgery itself, on the infected screw, without any need to extract the implant from the patient. This new material is in the process of being patented and remains a trade secret,” aforementioned the investigator.
In catch of the results, Palla believes that “it is possible to confirm that coatings with an antibacterial capability and which do not affect the proper integration of the implant into the jawbone have been developed.” She as well admits, however, that there is smooth a longsighted path to go ahead they bathroom be applied and ill-used during dental surgery: “Apart from all the trials that remain to be carried out, it would also be advisable to pursue the research a little further to optimize the results more.”
