Patients and Methods. 19 patients with maxillary tooth loss were treated with 20 Premiun Kohno ® Sweden-Martina internal connection and sandblasted and acid- etched surface implants for rehabilitation by transalveolar sinus elevation. Implants were loaded a er a healing free-loading period of 6 months.
Results. Clinical results indicate a survival and success rate of implants of 95%. One implant was lost during the healing period. e mean elevation height was 4.4 mm. 45% of implants were inserted in molar and 55% in premolar localization. A er a mean functioning period of 36.4 months, no late complications were reported. 94.4% of patients were restored with single crowns and 5.6% with xed bridges.
Conclusions. This study indicate that treatment with dental implants inserted in max- illa by ridge expansion constitute a successful implant treatment.
