Management of Complications Associated with Elevation of the Maxillary Sinus

When reduced dimension implants are not indicated in the atrophic posterior maxilla, because of the relevant reduction of residual alveolar crest volumes following atrophy and/or expansion of the maxillary sinus, sinus floor elevation with a crest or lateral approach has become a quite frequent surgical procedure in implant dentistry. These surgical procedures, although reliable, may expose also experienced surgeons to complications such as:

1) sinus membrane tears;

2) penetration/migration of implants into their maxillary sinus;

3) post-operative maxillary sinusitis.
