A Comparative Study Between Graftless and Grafted Maxillary Sinus Lift Procedures for Implant Placement

Dental implant survival requires the presence of peri-implant bone for complete and stable osseointegration. Grafted sinus lift procedures are predictable methods to augment deficient ridges, but may give rise to complications, comorbidities, and additional costs. Recent evidence showed positive outcomes of the graft-less sinus lift technique. However, studies comparing the outcome of the grafted and graft-less sinus lift procedures are still lacking. This study aims to compare the implant stability, bone density, and pocket depth outcomes between grafted and graft less sinus lift procedures for implant placement.
