A control group of 12 New Zealand participants had new conventional mandibular partial dentures made.

Four late implant failures in three participants occurred in New Zealand (two unilateral implant failures after 5 and 8\u00a0years and two bilateral implant failures in the same participant after 6 and 10\u00a0years); two unilateral late implant failures occurred in the Netherlands and no late failures in Colombia. Implant survival rate was 92% by 10\u00a0years. Resonance frequency measurements were taken at surgery implant stability quotient (ISQ) 62.44\u00a0\u00b1\u00a07.46; range 40 \u2013 79), baseline (<jats:styled-content style=\"fixed-case\">ISQ<\/jats:styled-content> 63.22\u00a0\u00b1\u00a06.17; range 50 \u2013 74) and after 3\u00a0years (<jats:styled-content style=\"fixed-case\">ISQ<\/jats:styled-content> 66.38\u00a0\u00b1\u00a06.77; range 55 \u2013 83).

For Stage I, principal prosthodontic maintenance issues were loose healing caps among 10 New Zealand participants, four Colombian participants and one Netherlands participant. For Stage 2, matrix activation and overdenture puncture fractures resulted in 41 events (25 participants) in New Zealand over 10\u00a0years, whilst over 3\u00a0years, there were 14 events in nine Colombian participants and six events in five Netherlands participants.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This clinical multicentre research complements previous case reports, case series, retrospective and prospective studies on the notion of implant\u2010assisted removable partial dentures for partially edentulous patients.
