Aim of this study was to evaluate the clinical use and the efficacy of Frialit-2 implant system.

Fifty nine patients received placement of Frilalit-2 implants(137 implants) in their maxillary anterior and posterior sites(40 and 97 implants). Intraoral & clinical examination, chart review and radiographs were taken from each patient.

The total implant survival rate was 92.7% after a mean follow-up period of 19.9 months.

The implant survival rate placed in anterior region was 97.5%.

The implant survival rate placed in posterior region was 90.7%.

The implant survival rate placed in atrophic posterior maxilla with advanced technique (GBR, Sinus elevation) was 87.2%.

The implant survival rate placed in type IV(D4) bone was 82%, while 95.7% in type III(D3), and 100% in type II(D2) bone.

Most of the failed implants(7 of 10) were removed during the maintenance stage after prosthodontic treatment.

It was concluded that Frialit-2 implant could be used satisfactorily in the esthetic anterior region, but the use in the posterior region, especially with poor bone quality and quantity, further studies are needed.
