Introduction. Implant technology is improving the clinical experience of osseointegrated implants with new designs and compositions of their surfaceso This study reports the results of evaluation of titanium implants with acid-etched surface and early loading in patients with unitary, partially and fully tooth loss. Methods. 100 TSA Defcon® implants were inserted in 36 patients. 63 implants were placed in the mandible and 47 in the maxilla. All implants were inserted in one-stage. Implants were loaded after a healing free-loading period between 6 weeks (mandible) and 8 weeks (maxilla). Clinical findings (implants and prosthodontics) were followed during 2 years. Results. Following healing (6-8 weeks), 19 patients were restored with single crowns (64,3%),9 patients with overdentures (26,7%) and 7 patients with fixed bridges (20%), respectively. Early complications (during the healing period) were reported in 3 implants that were removed by mobility.These results indicate a survival and success rate of implants of 97%. Conclusions. Clinical findings of this study suggest that use of etchet-surface titanium implants can achieve osseointegration and were loaded early as a successful treatment of patients with tooth loss.
