简要总结
implant placement in the posterior maxilla is problematic, not only due to inferior properties of bone but also due to loss of vertical bone height which happens after extraction of posterior teeth. when the required additional height is few millimeters, indirect transcresta sinus lifting procedures are recommended.
This study compares sinus lifting using the conventional osteotome versus the osseodensification with densah burs.
详细描述
a total of 12 patients with missing maxillary premolars or molars and with limited vertical bone height below the maxillary sinus floor will receive implants either with osteotome or with Densah burs transcrestal sinus lifting to compare clinically and radiographically transcrestal sinus lifting with Densah burs and osteotome with simultaneous implant placement
