The early loading of different surface-modified implants: a randomized clinical trial

Abstract Background Various surface treatment options have been adopted with the aim to improve osseointegration, reducing overall time. Implant stability of early loaded implants different modified surfaces was compared in present study. Methods Patients were selected from Department Oro-Maxillofacial Surgery and Stomatology at Semmelweis University. randomly received SA (alumina sandblasted acid-etched), NH (bioabsorbable apatite nanocoating) or SLA (large-grit acid-etched) implants. Outcome measures were: implant success, stability, periodontal parameters. The measured time placement (primary stability) six weeks after (prothesis delivery, secondary stability). Osstell Periotest applied take all measurements. primary three study groups Finally periimplant probing depth appearing months loading checked on 6 points around implant-supported prostheses. Shapiro–Wilk Mann–Whitney tests used for comparison between groups. Results A total 75 length diameter inserted into various positions. One failed spontaneously fourth week placement. survival rate 98,7%. Comparing values, data significantly improved every difference highest group, however, this not significant two other Good parameters experienced tested implants, independently by Conclusions With limitation study, showed trend higher result found group. Further studies longer follow-up are needed confirm preliminary results. Trial registration : Current Controlled Trials ISRCTN13181677; date registration: 04/03/2021. Retrospectively registered.
