HISTOLOGICAL EVIDENCE OF OSSEOINTEGRATION 4 YEARS AFTER IMPLANTATION - A CASE-REPORT

Histological examinations of clinically successful dental implants are very rare in the literature. This article presents a clinical case wh ere an ITI hollow-cylinder titanium implant type F (red mark, 16 mm) h ad to be removed simultaneously with the resection of a squamous cell carcinoma of the lower jaw. The duration of functional loading of the implant was 49 months. The fixture was situated at the margin of the t issue to be resected during tumor surgery and could therefore be prepa red as a histological specimen independent of the tumorous tissue. In the sections obtained, close contact of alveolar bone to the implant s urface was clearly visible. Together with the clinical success of the implant, criteria of osseointegration seems to have been matched. This observation represents the longest histological survery of a clinical ly successful fixture of this implant system.
