For the Ball System, three activation degrees of the matrix are included versus four and six color\u2010coded retention devices for the Locator R\u2010Tx\u00ae and the Novaloc\u00ae, respectively, to represent the complete regular retention devices panel. For each retention device or activation degree, eight samples are tested.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The initial retention range is similar between the Ball System (7.7 \u00b1 3.4 N \u2013 19.9 \u00b1 4.6 N) and the Novaloc\u00ae (2.0 \u00b1 0.5 N \u2013 18.9 \u00b1 1.4 N) and broader for the Locator R\u2010Tx\u00ae (3.3 \u00b1 5.0 N \u2013 60.2 \u00b1 6.0 N). In each attachment system, the initial retention of each retention device is significantly different from the others, except for the two most retentive Novaloc\u00ae ones. Retention devices were also classified according to their initial retention (low, medium, and maximum). In each retention group, the Novaloc\u00ae and the Ball System provided similar retention values lower than the Locator R\u2010Tx\u00ae.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Most of the retention devices tested provided an initial retention force of over 5 N for all three attachment systems. The Locator R\u2010Tx\u00ae had the most comprehensive range, and the Novaloc\u00ae seemed to provide the most reproducible values, unlike the Ball System due to the activation required by the operator.<\/jats:p><\/jats:sec>","DOI":"10.1111\/jopr.13729","type":"journal-article","created":{"date-parts":[[2023,7,13]],"date-time":"2023-07-13T10:45:36Z","timestamp":1689245136000},"page":"475-483","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Initial retention force of three attachment systems for implant retained\u2010mandibular overdentures: An in vitro study"],"prefix":"10.1111","volume":"33","author":[{"given":"Raphael","family":"Wakam","sequence":"first","affiliation":[{"name":"Unit\u00e9 de Recherche Biomat\u00e9riaux Innovants et Interfaces Faculty of odontology Universit\u00e9 Paris Cit\u00e9 Montrouge France"},{"name":"Prosthetics Department Oral Medicine Service P\u00f4le des Sp\u00e9cialit\u00e9s m\u00e9dico\u2010chirurgicales CHU Lille France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kwamivi B.","family":"Mawussi","sequence":"additional","affiliation":[{"name":"Unit\u00e9 de Recherche Biomat\u00e9riaux Innovants et Interfaces Faculty of odontology Universit\u00e9 Paris Cit\u00e9 Montrouge France"},{"name":"Universit\u00e9 Sorbonne Paris Nord Bobigny France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aur\u00e9lie","family":"Benoit","sequence":"additional","affiliation":[{"name":"Unit\u00e9 de Recherche Biomat\u00e9riaux Innovants et Interfaces Faculty of odontology Universit\u00e9 Paris Cit\u00e9 Montrouge France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2155-696X","authenticated-orcid":false,"given":"Caroline","family":"Gorin","sequence":"additional","affiliation":[{"name":"Laboratory URP2496 Orofacial Pathologies Imaging and Biotherapies Faculty of odontology Universit\u00e9 Paris Cit\u00e9 Montrouge France"},{"name":"Oral Medicine Service Prosthetics Department AP\u2010HP\/GH Nord Paris France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2023,8]]},"reference":[{"key":"e_1_2_8_2_1","article-title":"Interventions for replacing missing teeth: attachment systems for implant overdentures in edentulous jaws","volume":"10","author":"Payne AG","year":"2018","journal-title":"Cochrane Database Syst Rev."},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2010.02004.x"},{"key":"e_1_2_8_4_1","first-page":"601","article-title":"The McGill consensus statement on overdenture.
