Aim To assess whether outcome of immediate implant placement and immediate provisionalization after 1 year was non‐inferior to immediate implant placement and delayed provisionalization regarding Marginal Bone Level (MBL). Materials and Methods Forty patients with a failing tooth in the aesthetic zone were randomly assigned for immediate implant placement with immediate ( n = 20) or delayed ( n = 20) provisionalization. Follow‐up was at 1 month and after 1 year. The study was powered to detect a difference in MBL of <0.9 mm. Apart from MBL , soft tissue peri‐implant parameters, aesthetic indexes and patient satisfaction were assessed. Results After 1 year, MBL changes were −0.75 ± 0.69 mesially and −0.68 ± 0.65 distally mm for the immediate group and −0.70 ± 0.64 and −0.68 ± 0.64 mm for the delayed group respectively ( NS ). Regarding differences in means, non‐inferiority was observed after 1 year (mesially: Group A versus B: difference in mean 0.08 mm (95% CI −0.38 to 0.53, p = 0.71 distally: Group A versus B: difference in mean 0.09 mm (95% CI −0.37 to 0.56 mm, p = 0.66).No significant differences in the other outcome variables were observed. Conclusions This study showed that immediate placement and immediate provisionalization was non‐inferior to immediate placement with delayed provisionalization. In addition, although not powered for these outcome variables, no clinically relevant differences in other outcomes were observed ( www.isrtcn.com : ISRCTN 57251089).
