Introduction. The aim of this study was to report the outcome of treatment with dental implants inserted by bone expansion technique. Methods.56 patients with tooth loss were treated with 117 Microdent^® sandblasted surface implants for rehabilitation by bone expansion technique with Microdent^® screw bone expanders. Implants were loaded after a healing free-loading period of 3-6 months according insertion in mandible or maxilla. Results. Clinical results indicate a survival and success rate of implants of 98,3%. 2 implants were lost during the healing period. 90,5% of implants were inserted in maxilla and 9.5% in mandible. After a mean functioning period of 14,1 months, no late complications were reported. 59.1% of patients were restored with single crowns; 31.1% with fixed bridges; 4.9% with fixed rehabilitations and 4.9% with overdentures. Conclusions. This study indicate that treatment with dental implants by bone expansion constitute a alternative successful implant treatment.
