Solution of complications in the sinus lift with lateral window procedure


The reabsorption of the alveolar process in the posterior maxillary region as a result of dental loss implies, in a high percentage of cases, the need to incorporate regenerative techniques in the rehabilitation treatment plan such as sinus lift with lateral window.

This is a regenerative technique that is well described in the literature and with proven predictability in the results. However, due to the anatomical environment in which the maxillary sinus is located, there are no generalised defined protocols, and it is in this section that the surgeon’s experience and knowledge play a key role in the statistics of treatment success.

During the presentation, the sinus floor lift technique with access through the maxillary lateral wall will be described in a basic way and the description of the treatment of the different complications that may arise intraoperatively will be detailed.
