Ungraded means an effect was reported without a GRADE rating; it is not a gap. No studies means the review found nothing to answer the question. The six categories are a display order, not a score.

Review question

ElementPlanned (methods)Found (results)
PopulationPeople who received osseointegrated root-formed oral/dental implants and were followed up for at least 1 year with the implant functionally loaded; patients with bone grafting, guided tissue regeneration or immediate placement in fresh extraction sockets were excluded1512 participants and 3230 implants; adults; 6 Italy, 5 New Zealand, 5 Sweden, 3 Netherlands, 2 Korea, 1 Turkey, 1 Germany, 1 Switzerland, 3 multicentre European
InterventionOral/dental implant treatment for replacing missing teeth with implants of a given material, shape and/or surface preparation38 different implant types compared, differing in surface preparation, shape, degree of titanium purity and titanium alloys (all commercially pure titanium or alloys) (n=38 types)
ComparisonImplants of a different material, shape and/or surface preparation (different implant type)Different implant type (see comparisons)
OutcomesPrimary: implant failure (biological or mechanical). Secondary: radiographic marginal bone level change; occurrence of peri-implantitisImplant failure (n=27); Marginal bone level change (n=NA); Peri-implantitis (n=4); Early implant failure (turned vs roughened) (n=7)
Study designsAll randomised controlled trials of oral/dental implants for replacing missing teeth comparing different implant types, with at least 1 year functional loadingRandomised controlled trials (parallel-group and split-mouth)
TimingAt least 1 year with the implant functionally loaded1 year; 3 years; 5 years; 10 years
