Aim: The aim of this study was the evaluation of long term results of the treatment concept 'immediate loading' in the anterior mandible and the examination of different factors which exert influence on the success.
Material and method: A total number of 321 implants were inserted in 74 patients and were splinted with a bar directly after surgery and restored with an overdenture within 24 hours. Clinical and radiological examinations were performed.
Results: The recorded parameters approve overall healthy hard and soft tissue conditions. More than 90% of the implants do not show any inflammation. The vertical bone loss, determined at the last recall, amounted a mean value of 0.55 mm. The acquired survival rate is 99.03% for a maximum observation period of 659 days (median period 10.3 months). Depending on the crestal level at insertion there could also be observed a gain of crestal bone. A significant correlation between vertical bone loss and age, recall interval, kind of prosthetic restoration of the maxilla and mandible could be demonstrated with an univariate analysis of variance.
Conclusion: The collected data show that for the immediate loading of at least four parallel walled transgingival implants stable periimplant parameters can be observed. The success rate of 95.6% for the examined treatment concept is comparable with the findings of delayed loaded implants in this indication.
