Summary

The aims of the present retrospective 25-year study of a sample of 459 patients with 753 sandblasted and acid-etched (SLA) titanium oral implants are:

* to assess the clinical parameters at SLA implants after 25 years in function
* to assess the crestal bone levels at SLA implants after 25 years in function
* to assess and compare the microbiological conditions at SLA implants and their adjacent teeth after 25 years of function
* to assess the periodontal conditions in patients having received SLA implants 25 years ago
* to establish a baseline data set for future prospective studies on patients having received SLA implants 25 years ago
* to assess the incidence rates of biological, technical, traumatic failures / complications with SLA implants
* to assess the incidence rates of technical failures / complications with prosthetic components on SLA implants
* to assess the incidence rates of biological, technical, mechanical, esthetic failures / complications with prosthetic reconstructions on SLA implants
* to find potential risk factors for biological failures / complications with SLA implants; i.e. patients having lost their teeth due to different reasons (e.g. partial anodontia, caries, periodontitis, endodontic failure, trauma, vertical root fracture), (ii) to calculate the success rates using different thresholds set as success criteria, (iii) to evaluate the influence of medical conditions and tobacco smoking on the long-term prognosis of titanium oral implants, and (iv) to assess the frequency and quality of maintenance
* to find potential risk factors for mechanical, technical, esthetic failures/complications with reconstructions seated on SLA implants
* to assess the treatment need and utility of implant therapy after 25 years in patients having received SLA implants
