Short communication: Cemented implant reconstructions are associated with less marginal bone loss than screw?retained reconstructions at 3 and 5 years of loading

Objectives To analyse whether there is a difference in marginal bone levels (MBL) and the respective changes between cemented screw-retained reconstructions at 3 5 years of loading. Methods Radiographic data from 14 prospective multicentre clinical trials following implant loading with fixed (CEM) or (SCREW) 3- to 5-year follow-up were retrieved database. MBL assessed initiation (BL), (FU-3) (FU-5) thereafter. The presence peri-implantitis was also determined. Results Data 1,672 implants BL, 1,565 FU-3 1,109 FU-5 available. mean amounted 0.57 mm (SD 0.87) 0.55 0.86) 0.65 1.18) FU-5. At FU-3, 0.44 0.65) group CEM 0.63 0.99) SCREW showing significant groups (intergroup <0.05). FU-5, 0.42 0.77) 0.80 1.37) SCREW, again differences both (p < .05). BL 0.11 1.02) (bone loss) ?0.17 1.03) gain) CEM. Similarly, 0.23 1.31) ?0.26 1.27) prevalence 6.9% 5.6% p = .29063) FU-3. 4.6% 6.2% .28242). Conclusion Cemented compared revealed higher similar rates during years. two groups, however, appear be clinically negligible.
