Sinus floor elevation
An external sinus lift can be performed under local anaesthesia. If the dorsal residual bone height is 4-6 mm, an external sinus lift is indicated, sometimes with primary implantation. If the dorsal residual bone height is <4 mm, an external sinus lift with secondary implantation is indicated. Primary implantation can be performed when primary stability has been achieved.
