Bone Height Gain Following Transcrestal Sinus Floor Elevation Using Piezoelectric Surgery Versus The Conventional Osteotome Technique

Missing teeth usually result in functional and cosmetic deficits. Traditionally, they have been restored with dentures or fixed bridges. However, dental implants represent an excellent alternative which rely on the maintenance of a direct structural and functional connection between living bone and implant surface, which is termed osseointergration. When sufficient bone is available in maxilla, implant rehabilitation has shown high success rates of 84-92 %. Atrophy of the alveolar crest and pneumatization of the maxillary sinus limits the quality and quantity of residual bone, therefore complicating the placement of implants in the posterior maxillary area.
