Review question
| Element | Planned (methods) | Found (results) |
|---|---|---|
| Population | Partially edentulous patients rehabilitated with implant-supported prostheses | Partially edentulous patients with implants (n=267 implants; 4 retrospective clinical studies) |
| Intervention | Exposure: baseline vertical implant positioning relative to adjacent teeth (IP-CEJ and IP-ABL distances, radiographic) | Baseline IP-CEJ (3 studies) and IP-ABL (4 studies) vertical distances |
| Comparison | Different baseline values of vertical implant positioning analyzed as a continuous variable | Baseline values analyzed as continuous variables; no categorical comparison |
| Outcomes | Primary: peri-implant marginal bone loss between baseline and at least 12 months; secondary: implant survival and success, prevalence of mucositis and peri-implantitis | Baseline IP-CEJ pooled mean 4.69 mm; baseline IP-ABL pooled mean 2.13 mm; marginal bone loss at 12 months pooled mean 0.21 mm (3 studies); secondary outcomes not reported |
| Study designs | Clinical human studies including RCTs, prospective and retrospective studies with at least 10 participants | Four retrospective clinical studies (n=4) |
| Timing | Radiographic marginal bone loss after at least 12 months of follow-up | Follow-up 12 to 96 months across studies; 1-year data used for marginal bone loss pooling |
