Although periodontal therapy has been shown to achieve predictable, long-term results, there comes a point when advanced crestal bone loss and trifurcation involvement make maintenance of teeth less predictable. That same crestal bone loss, combined with maxillary sinus pneumatization, creates a difficult situation for the placement of implants. Maxillary sinus elevation has proven to be a highly successful preprosthetic procedure for the replacement of that lost bone and for the successful placement of dental implants to restore the posterior occlusion. Over the past 30 years the approach to maxillary sinus elevation has evolved dramatically. It has become more predictable and can be accomplished with less morbidity. This presentation will follow that evolution from inception to present day and discuss future directions presently under investigation.
