The impact of local and systemic factors on the incidence of failures up to abutment connection with modified surface oral implants
Abstract
This study aimed to assess the influence of systemic and local bone and intra-oral factors on the occurrence of early TiUnite implant failures. Materials and Methods: A total of 283 consecutive patients (187 females; mean age 56.2), who received a total of 720 TiUnite implants, at the Department of Periodontology of the University Hospital of the Catholic University of Leuven, were prospectively followed.
Results and Conclusion: A global failure rate of 1.9% was recorded. Owing to the very few failures, no definitive conclusion concerning statistical significance can be achieved.
However, a tendency for more failures was noticed for apical lesions, vicinity with natural dentition, smoking, hormone replacement, gastric problems, Crohn's disease, diabetes I and radical hysterectomy.
