Clinical evidence and Science 29 Implant fracture analysis over 10 years In a dental hospital in Korea all implants placed over a period of 10 years and additionally followed-up over a further three years were retrospectively investigated for implant fractures. Over 19 000 internal connection implants of 14 different implant manufacturers (Astra-Tech, Bego, Biohorizons, Dentis, Osstem, Zimmer and others) could be included and evaluated for potential risk indicators. In this study 1317 CAMLOG® implants were placed and revealed a fracture incidence of 0.73% which was below the overall incidence rate of 0.92%. For the actual K-Line series (CAMLOG® implants, marketed since 2008) no fractures were reported (Lee et al. 2019 (19)). KEY TAKE OUTS: HIGH LONG-TERM SUCCESS WITH CAMLOG® IMPLANTS Irrespective of the choice of the implant dimensions and the selected treatment plan e.g., immediate or delayed implant placement, CAMLOG® SCREW-LINE implants showed high survival and success rates comparable or even higher to the average of the implant systems on the market. Also, real-world data from studies in daily dental practices revealed predictable and satisfying outcomes for CAMLOG® implants. Even in more complex indications like the sinus floor elevation the implant system convinced with its survival and success rates comparable to those achieved in healed alveoli. The implant fracture rate of the CAMLOG® implants identified in a retrospective study with an observation period of more than 10 years was considerably lower than that of other implant systems. With the given reliability of the CAMLOG® implants the users can apply it with a level of confidence. High success rate of CONELOG® implants with the Promote® Surface With the market introduction of the CONELOG® implants in 2010 clinical studies were initiated to collect data on both safety and performance. The already established features of the system like the sandblasted and acid-etched Promote® Surface, the Platform-Switching, and the outer geometry were evaluated in numerous mechanical, in-vitro, and clinical studies for the CAMLOG® Implant System and were understood to be the state-of-the-art. In an observational multicenter clinical study performed in six centers in Germany, the use and performance of the CONELOG® implants for single tooth restorations and fixed partial dentures were prospectively documented in daily dental practice (Ackermann et al. 2020 (20), Cacaci et al. 2019 (21)). In yearly follow-ups the peri-implant status, any complications, and the patient satisfaction from 94 patients with 130 implants were collected with good results: The cumulative survival rate up to 7-year post-loading was 96.6%. Few further complications like increased bone loss (> 2 mm) in three patients and crown loosening (n=2) and chipping of crown (n=1) on a prosthetic level were reported. At the last follow-up, all patients reported to be satisfied with their restoration. In summary, the results demonstrated successful functional and esthetic outcomes of restorations with CONELOG® implants from both the dentist as well as the patient side. Survival rates > 95% were also achieved in other clinical studies and retrospective analyses with CONELOG® implants (Tab. 4). Success with short implants of 7 mm length Short implants are a viable option to treat clinical situations with limited vertical bone height. Instead of performing a sinus augmentation and vertical augmentation in atrophic maxilla or mandible respectively which is associated with costs and comes with chance for possible complications short implants can be inserted. However, compared to longer implants, bone loss as well as typically greater crown-implant ratios are potentially more detrimental with short implants.
