Implants over maxillary posterior area are mostly challenged by insufficient bone height or bone volume. Sinus lift procedure is usully applied as a typical approach to tackle this difficult clinical situation. It is of interest for patients or dentists to explore a proper ways to restrain the size of the surgical field, shorten theoperation time, minimize the post-operative swelling, save the regeneration related materials, and reach the desirable results at the same time. The crestal sinus elevation technique satisfys above requirements. Present article covers the development of this technique, the factors suppose to be consided. the morphological variations of the maxillary sinus and the bone quality of the alveolar ridge, the progress of surgical wound healing, as wll as the long-term success rates of this technique.
