Tilted implants to support fixed partial dentures

shutterstock_88585900

This review of marginal bone loss and implant survival rate of tilted implants compared with those of axial implants for implant-supported fixed partial dentures (ISFPDs) included 9 studies. The findings suggest no different in survival rates between the two implant types but the possibility of more marginal bone loss with tilted implants.The quality of evidence is low.

This review of the outcomes of early and delayed loading of dental implants included 18 RCTs. The findings suggest that early and delayed loading protocols had similar clinical outcomes. However none of the included studies was at a low risk and 13 of the 18 studies were considered to be at high risk of bias. While the findings are similar to other reviews teh availabel evidence is of low to very low certainty.
