• AMSTAR 2 |
| Aim | To assess the methodological quality (AMSTAR 2) of published systematic reviews relating to all prosthodontic ceramic implant frameworks, abutments and restorations. |
| Level of Investigation | Descriptive |
| Summary of Findings | The majority of included systematic reviews (15 out of 16) scored critically low on quality with more than one critical flaw when assessed using the AMSTAR-2 tool. Most systematic reviews assessed lacked analysis of the effects of the risk of bias and heterogeneity of the included studies. 11/16 of the assessed systematic reviews failed to fulfil the protocol registration criteria and 5 did not perform an adequate literature search. 11 of the assessed systematic reviews did not satisfy the criteria for a competent risk of bias assessment and hence did not account for the risk of bias in their interpretation. The source of funding of the primary studies (RCTs and NRSIs) investigated in 13 of the SRs was not reported. |
