OSTEOTOMES CONVEX STRAIGHT with DOUBLE STOPPER JULL-DENT 004 An internal sinus lift is made through the maxillary jaw. This technique is often used when there is minimal bone shrinkage or when a single implant is placed. Furthermore, it is used for increasing the density of poorly mineralised and relatively malleable bone via condensation, so that reliable results which remain stable long term can be achieved. The osteotomes are designed for penetrating the sinus floor in a controlled manner and raising the mucous membrane, so that adequate amounts of bone augmentation material can be placed to ensure afterwards that the implant is retained firmly.
