This technique is a delicate manoeuvre that involves the elevation of the sinus membrane off the maxillary sinus floor to augment the bone volume where there is not enough space for dental implants. The sinus lifting technique consists in placing a bone graft in the sinus without modifying the nasal cavity.
CT scan imaging provide the information we need about the sinuses, the status of the membrane, the thickness of the bone crest, the morphology of the sinus floor, and the thickness of the vestibular and palatine walls of the sinus. This imagery allows us to adapt our surgical techniques to the anatomical specificity of the area (e.g., blood vessels, nerves). The sinus membrane lines the sinus walls and is extremely thin.
The aim of the intervention is to position the bone-addition materials between the alveolar bone and the sinus membrane, without damaging the membrane.
The piezosurgery techniques used do not affect the soft tissue and leaves the membrane perfectly intact. Moreover, the specialised instruments used to lift it determine an over 99% success rate of the sinus lifting.
