Introduction/purpose: The purpose of this retrospective clinical study is to evaluate and to compare clinical outcome of clinical trial within type of bar construction and type of implant system for treatment with implant - retained mandibular overdentures during a 15 - year follow - up period.

Materials and methods: A total of 123 patients (total 546 implants) with an edentulous mandible received treatment in Department of Prosthodontics and Implantology at the Medical University Graz with following types of implants - Frialit 2, XIVE and IMZ during time from 01/1990 till 01/2005. The evaluation included clinical and X-Ray data, after - treatment evaluation and patient`s satisfaction depending on type of bar construction and implant system.

Results: All complications that have arisen in this term had been revealed.

Further all complications have been sorted depending on type of implant system and from type of bar construction. All complications have been presented by following groups; complications with marginal soft tissue, complications with osseointegration of implants (implants loosing and atrophy of alveolar bone tissues), complications with bar constructions and complications with prosthesis.

Conclusion: On the basis of the received results, we could review that the Frialit 2 and Xive implant systems have a better survival rate and clinical implant performance than IMZ system. These systems should be the method of choice for the edentulous mandible. It`s necessary to add that the frequency of complications with Dolder bar constructions was slightly more expressed than with individual milled - bar constructions.
