This rapid technology review of the longevity of removable dental prostheses focused on complete dentures and partial plastic or metal dentures. It included a small number of systematic reviews, which were of limited quality and based on a small number of small studies. While good 5 year survival rates were found, the quality of the evidence means that the findings should be interpreted cautiously.

This technology review looked at the effectiveness of crowns on root treated teeth. 3 systematic reviews and 4 non-randomised studies were included. They found that the short term survival with crowns or direct fillings is comparable but long term root canal treated teeth may have better survival.

This review included 12 small in vitro and in vivo studies of Cone Beam Computed Tomography (CBCT) for the diagnosis of a root fracture. While the data suggest the ability to detect root fractures in non-endodontically treated teeth, the findings should be interpreted with caution.

This review included 13 small studies of limited quality. While the available evidence suggests there may be no difference, further long-term high quality studies are required to confirm if this is the case.

This review of dental implants failure in males and females included 91 studies. The majority were retrospective with only 4 RCTs. While suggesting higher failure rates in males than females, the study quality and confounders mean that the results should be treated with caution.

Only 12 small studies of limited quality were available for this review on CAD-CAM-fabricated implant-supported restorations. While they showed promising short-term outcomes, they should be interpreted with caution.
