However, the role of biofilms in sliding contacts remains unclear. Friction during sliding was analyzed for titanium covered with mixed biofilms consisting of Streptococcus mutans and Candida albicans. The morphology of biofilms on titanium surfaces was evaluated before, during, and after sliding tests. Very low friction was recorded on titanium immersed in artificial saliva and sliding against alumina in the presence of biofilms. The complex structure of biofilms, which consist of microbial cells and their hydrated exopolymeric matrix, acts like a lubricant. A low friction in sliding contacts may have major significance in the medical field. The composition and structure of biofilms are shown to be key factors for an understanding of friction behavior of dental implant connections and prosthetic joints. For instance, a loss of mechanical integrity of dental implant internal connections may occur as a consequence of the decrease in friction caused by biofilm formation. Consequently, the study of the exopolymeric matrix can be important for the development of high-performance novel joint-based systems for medical and other engineering applications. <\/jats:p>","DOI":"10.1177\/0022034510378428","type":"journal-article","created":{"date-parts":[[2010,10,6]],"date-time":"2010-10-06T03:59:35Z","timestamp":1286337575000},"page":"1470-1475","source":"Crossref","is-referenced-by-count":50,"title":["Biofilms Inducing Ultra-low Friction on Titanium"],"prefix":"10.1177","volume":"89","author":[{"given":"J.C.M.","family":"Souza","sequence":"first","affiliation":[{"name":"Centre for Mechanical and Materials Technologies (CT2M), Universidade do Minho, P-4800\u2013058, Guimar\u00e3es, Portugal"}]},{"given":"M.","family":"Henriques","sequence":"additional","affiliation":[{"name":"IBB\u2014Institute for Biotechnology and Bioengineering, Universidade do Minho, P-4710\u2013057 Braga, Portugal"}]},{"given":"R.","family":"Oliveira","sequence":"additional","affiliation":[{"name":"IBB\u2014Institute for Biotechnology and Bioengineering, Universidade do Minho, P-4710\u2013057 Braga, Portugal"}]},{"given":"W.","family":"Teughels","sequence":"additional","affiliation":[{"name":"Department. of Periodontology, Katholieke Universiteit Leuven, B-3000 Leuven, Belgium"}]},{"given":"J.-P.","family":"Celis","sequence":"additional","affiliation":[{"name":"Department MTM, Katholieke Universiteit Leuven, Kasteelpark Arenberg, 44\u2014bus 2450, Leuven, B-3001, Belgium"}]},{"given":"L.A.","family":"Rocha","sequence":"additional","affiliation":[{"name":"Centre for Mechanical and Materials Technologies (CT2M), Universidade do Minho, P-4800\u2013058, Guimar\u00e3es, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2010,10,5]]},"reference":[{"key":"bibr1-0022034510378428","first-page":"11","volume":"10","author":"Alcoforado GA","year":"1991","journal-title":"J Parodontol"},{"key":"bibr2-0022034510378428","doi-asserted-by":"publisher","DOI":"10.1177\/154405910308200316"},{"key":"bibr3-0022034510378428","doi-asserted-by":"publisher","DOI":"10.1021\/bm0493990"},{"key":"bibr4-0022034510378428","doi-asserted-by":"publisher","DOI":"10.1016\/j.mimet.2006.04.023"},{"key":"bibr5-0022034510378428","doi-asserted-by":"publisher","DOI":"10.1126\/science.284.5418.1318"},{"key":"bibr6-0022034510378428","doi-asserted-by":"publisher","DOI":"10.1177\/00220345630420051301"},{"key":"bibr7-0022034510378428","doi-asserted-by":"publisher","DOI":"10.1067\/mpr.2001.112796"},{"key":"bibr8-0022034510378428","first-page":"826","volume":"19","author":"Guindy JS","year":"2004","journal-title":"Int J Oral Maxillofac Implants"},{"key":"bibr9-0022034510378428","doi-asserted-by":"publisher","DOI":"10.1177\/154405910608500805"},{"key":"bibr10-0022034510378428","doi-asserted-by":"publisher","DOI":"10.1016\/j.wear.2006.03.032"},{"key":"bibr11-0022034510378428","doi-asserted-by":"publisher","DOI":"10.1126\/science.1070784"},{"key":"bibr12-0022034510378428","doi-asserted-by":"publisher","DOI":"10.1016\/S0043-1648(03)00561-1"},{"key":"bibr13-0022034510378428","first-page":"285","volume":"21","author":"Le Mogne T","year":"1992","journal-title":"Wear"},{"key":"bibr14-0022034510378428","doi-asserted-by":"publisher","DOI":"10.1016\/j.actbio.2005.09.004"},{"key":"bibr15-0022034510378428","doi-asserted-by":"publisher","DOI":"10.1002\/jbm.b.31211"},{"key":"bibr16-0022034510378428","unstructured":"Marsh PD, Martin MV (1999).
