Purpose The aim of this prospective clinical trial was to assess clinical, radiological, and esthetic outcomes of immediate‐loaded post‐extractive implants after 1 year of follow‐up. Materials and Methods Twenty‐four consecutive patients (15 females and nine males) with a mean age of 47.27 years (range 35–65) requiring single‐tooth extraction in the maxillary or mandibular anterior or premolar areas were enrolled. Twenty‐five N obel A ctive ® implants ( N obel B iocare, G öteborg, S weden) were placed and loaded immediately after tooth extraction. The definitive prosthetic restoration was delivered 6 months later. Clinical parameters, marginal bone loss, as well as, pink and white esthetic scores ( PES and WES ) were evaluated at 3, 6, and 12 months after implant placement. Results After 12‐month follow‐up period, a success rate of 91.67% was reported: Two of the 25 initially placed implants were lost after 4 weeks due to lack of osseointegration. The mean marginal bone loss after 1‐year follow‐up was 0.383 ( SD ± 0.749) at mesial site and 0.278 ( SD ± 0.595) at distal site. No statistically significant changes in the full‐mouth plaque score ( FMPS ) and in the full‐mouth bleeding score ( FMBS ) were observed from baseline to 12 months. The mean total PES / WES was 17.13 ± 1.91 (range: 13–20). None of 23 implants had an overall score <12 (threshold of clinical acceptability). Conclusion Within the limitations of the present study, when careful patient selection and strict clinical protocol are observed, the immediate placement and loading of a single N obel A ctive ™ implant in a fresh extraction socket may be considered a valuable and predictable option in terms of implant success as well as hard and soft tissues stability.
