Abstract
ABSTRACT Purpose: To evaluate the thickness of the sinus membrane in contact with implants inserted 10 years earlier using an augmentation procedure without grafting material, and to identify adverse events correlated with implant protrusion into the sinus. Materials and Methods: Osteotome sinus floor elevations (OSFE) were performed without grafting material. Implants (Straumann AG) were placed simultaneously, and all protruded into the sinus. After 10 years, implants were considered viable in the absence of mobility, pain, infection, or continued radiolucency. Sinus health was assessed using cone-beam computed tomography (CBCT) and through a questionnaire in which patients reported any sinusitis symptoms they may have experienced. Results: The controlled implants (21 implants, 13 patients) were osseointegrated. Membrane thickness was <2 mm in 11 patients and 2–3 mm with flat thickening in two patients. None of the patients exhibited clinical or radiographic signs of sinusitis. Conclusions: No sinus complications were observed after 10 years. The initial protrusion of implants into the sinus did not influence long-term sinus health. Maintaining successful integration is therefore key to avoiding sinus complications.
