However, the full restoration of tooth functions relies on the bone-healing period before positioning the abutment and the crown on the implant, with the associated risk of post-operative infection. This study aimed at developing a homogeneous and adherent thin calcium phosphate antibacterial coating on titanium dental implants by electrodeposition to favor both implant osseointegration and to limit peri-implantitis. By combining global (XRD, FTIR-ATR, elemental titration) and local (SEM, Raman spectroscopy on the coating surface and thickness) characterization techniques, we determined the effect of electrodeposition time on the characteristics and phases content of the coating and the associated mechanism of its formation. The 1-min-electrodeposited CaP coating (thickness: 2 \u00b1 1 \u03bcm) was mainly composed of nano-needles of octacalcium phosphate. We demonstrated its mechanical stability after screwing and unscrewing the dental implant in an artificial jawbone. Then, we showed that we can reach a high copper incorporation rate (up to a 27% Cu\/(Cu+Ca) molar ratio) in this CaP coating by using an ionic exchange post-treatment with copper nitrate solution at different concentrations. The biological properties (antibiofilm activity and cytotoxicity) were tested in vitro using a model of mixed bacteria biofilm mimicking peri-implantitis and the EN 10993-5 standard (direct contact), respectively. An efficient copper-doping dose was determined, providing an antibiofilm property to the coating without cytotoxic side effects. By combining the electrodeposition and copper ionic exchange processes, we can develop an antibiofilm calcium phosphate coating on dental implants with a tunable thickness and phases content.<\/jats:p>","DOI":"10.3390\/jfb14010020","type":"journal-article","created":{"date-parts":[[2022,12,30]],"date-time":"2022-12-30T03:18:18Z","timestamp":1672370298000},"page":"20","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Antibacterial Electrodeposited Copper-Doped Calcium Phosphate Coatings for Dental Implants"],"prefix":"10.3390","volume":"14","author":[{"given":"Camille","family":"Pierre","sequence":"first","affiliation":[{"name":"CIRIMAT, Universit\u00e9 de Toulouse, CNRS, Toulouse INP-ENSIACET, 31030 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ghislaine","family":"Bertrand","sequence":"additional","affiliation":[{"name":"CIRIMAT, Universit\u00e9 de Toulouse, CNRS, Toulouse INP-ENSIACET, 31030 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Iltaf","family":"Pavy","sequence":"additional","affiliation":[{"name":"Laboratoire de G\u00e9nie Chimique, Universit\u00e9 de Toulouse, CNRS, Universit\u00e9 Paul Sabatier, Facult\u00e9 des Sciences Pharmaceutiques, 31062 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olivier","family":"Benhamou","sequence":"additional","affiliation":[{"name":"Arts Loi Dental Clinic, Rue de la Loi 28, 1040 Bruxelles, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christian","family":"Rey","sequence":"additional","affiliation":[{"name":"CIRIMAT, Universit\u00e9 de Toulouse, CNRS, Toulouse INP-ENSIACET, 31030 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7505-1000","authenticated-orcid":false,"given":"Christine","family":"Roques","sequence":"additional","affiliation":[{"name":"Laboratoire de G\u00e9nie Chimique, Universit\u00e9 de Toulouse, CNRS, Universit\u00e9 Paul Sabatier, Facult\u00e9 des Sciences Pharmaceutiques, 31062 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5009-1973","authenticated-orcid":false,"given":"Christ\u00e8le","family":"Combes","sequence":"additional","affiliation":[{"name":"CIRIMAT, Universit\u00e9 de Toulouse, CNRS, Toulouse INP-ENSIACET, 31030 Toulouse, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"104","DOI":"10.1016\/j.jhin.2009.02.010","article-title":"A review of dental implants and infection","volume":"72","author":"Pye","year":"2009","journal-title":"J.
