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
| Element | Planned (methods) | Found (results) |
|---|---|---|
| Population | People 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 excluded | 1512 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 |
| Intervention | Oral/dental implant treatment for replacing missing teeth with implants of a given material, shape and/or surface preparation | 38 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) |
| Comparison | Implants of a different material, shape and/or surface preparation (different implant type) | Different implant type (see comparisons) |
| Outcomes | Primary: implant failure (biological or mechanical). Secondary: radiographic marginal bone level change; occurrence of peri-implantitis | Implant failure (n=27); Marginal bone level change (n=NA); Peri-implantitis (n=4); Early implant failure (turned vs roughened) (n=7) |
| Study designs | All randomised controlled trials of oral/dental implants for replacing missing teeth comparing different implant types, with at least 1 year functional loading | Randomised controlled trials (parallel-group and split-mouth) |
| Timing | At least 1 year with the implant functionally loaded | 1 year; 3 years; 5 years; 10 years |
