Peri-implant tissue and the longevity of restoration

The clinical success was analysed several times, based upon the good results obtained and unfortunately not on a basis of correct scientific researches, as the cellular and ultrastructural investigations. In the randomized study a more numerous failures are seen in the first, respectively second year, after the application of the implant. The failures were predominantly observed in case of mandible implants. The quality of the bone is an essential factor for the success of the implant without correlation with the age of the patient. The most objective choice of the patients as well as a correct conceived and executed therapeutical plan, the follow-up cooperation with the patient, in what concerns the strict oral hygiene, would had to an increasing number of successfully solved cases. The success of the implant may be ensured when besides the content of the patient, the long-term stability of the soft and bone peri-implant tissues is achieved. By this is also obtained by morphological stability, which may be evaluated following clinical X-ray parameters. This stability is under dependence of the biological status. Conclusively this means an established biomechanical balance and stable relationships between the immune defense system of the least and the pathogenic potential of the microorganisms.
