Cement-or screw-retained implant-supported prostheses and peri-implant disease


This review comparing the incidence of peri-implant disease with cement- and screw-retained prostheses included 6 RCTs. The findings suggest no difference in level of peri-implant disease with cement- or screw retained prosthesis. However, the studies are small none of them are at low risk of bias. Consequently the findings should be interpreted cautiously.

Peri-implantitis – adjunctive measures to non-surgical peri-implant therapy


This review of the effectiveness of patient-performed or administered adjunctive measures to non-surgical peri-implantitis therapy included 9 RCTs. A wide range of interventions were tested but the studies were mainly small with only one being at low risk of bias. Consequently addition high quality well conducted studies are needed on both the prevention and treatment of peri-implant disease.
