When the posteriormaxilla is atrophic, the reference standard of care would be to performsinus augmentation with an autologous\nbone graft through the lateral approach and delayed implant placement. However, placement of short implants with the osteotome\nsinus floor elevation technique andwithout graft can be proposed for an efficient treatment of clinical cases with a maxillary residual\nbone height of 4 to 8 mm. The use of grafting material is recommended only when the residual bone height is ?4 mm. Indications\nof the lateral sinus floor elevation are limited to cases with a residual bone height ? 2mm and fused corticals, uncompleted healing\nof the edentulous site, and absence of flat cortical bone crest or when the patient wishes to wear a removable prosthesis during the\nhealing period. The presented case report illustrates osteotome sinus floor elevation with and without grafting and simultaneous\nimplant placement in extreme conditions: atrophic maxilla, short implant placement, reduced healing time, and single crown\nrehabilitation. After 6 years, all placed implants were functional with an endosinus bone gain.
