Sammanfattning

Osteotome-mediated sinus floor augmentation and simultaneous implant placement may be used in cases with limited vertical atrophy of the maxillary premolar and molar region with a need of an increased vertical height of the alveolar ridge, thereby enabling the insertion of a longer implant. The Schneiderian membrane including the original maxillary sinus floor is elevated using calibrated osteotomes or hydraulic technique. The created compartment between the elevated sinus membrane and the original floor of the maxillary sinus is often filled with a grafting material through the prepared implant site before placement of the implant. Systematic reviews and meta-analyses have revealed high survival rate of supras-tructure and implant, limited peri-implant marginal bone loss, vertical bone regeneration, few complications, and high patient satisfaction. The implant survival is significantly improved, when the implant length is 8 mm or longer and when the initial vertical height of the alveolar process is more than 6 mm. Osteotome-mediated sinus floor augmentation increases the vertical height of the alveolar process by approximately 2-5 mm and bone regeneration is improved by using a grafting material. In the present review, the current knowledge about osteotome-mediated sinus floor augmentation and simultaneous implant placement is presented. However, further long-term randomised controlled trials assessing placement of adjacent implants within the same region, various implant lengths, and the necessity of a grafting material are needed before evidence-based treatment guidelines can be provided on implant placement in the posterior part of the maxilla in conjunction with osteotome-mediated sinus floor augmentation.
