The sinus floor elevation procedure has been used to be one of the predictable treatments for rehabilitation of atrophic and pneumatized edentulous posterior maxilla. Sinus elevation with simultaneous implant placement could be an optimal procedure due to reduction in surgical procedures and to patient’s convenience. This study reports the successful results of sinus elevation with the sand blasted, large grit, acid-etched (SLA) surfaced implant(ITI dental imiplant system, Straumannⓡ, Basel, Switzerland) placement simultaneously. In the first case, the height of residual ridge was 2~4mm. Autogeneous bone from ramus and alloplast(Macroporous biphasic calcium phosphate-MBCP, Biomatlanteⓡ Sarl, Nantes, France) were applied after sinus elevation through lateral window approach. SLA surfaced implants(ITI) were installed simultaneously. Result after 17 months was showed successfully. In the second case, the height of residual ridge was 3~5mm. Allograft(Freeze dried bone allograft-FDBA, Oragraft, Lifenet health, Virginia Beach, VA, USA) and alloplast(MBCP) were used for sinus graft. All procedures were followed as in the first case. Result after 9 months was showed successfully. In conclusion, this study presented successful results, when sinus elevation through window approach with mixed graft material was performed with simultaneous SLA surfaced implant placement on severe atrophied maxillary alveolar ridge, minimizing patient discomfort.
