Abstract：Objective:To explore the accuracy of posterior maxillary bone height obtained by CBCT and to assess the clinical results of a modified osteotome technique to lift sinus floor in elderly patients with osteoporosis without grafting materials.Methods:26 cases of elderly patients with osteoporosis with maxillary posterior teeth loss were enrolled and analyzed by using the CBCT (ProMax3D) system for imaging diagnosis of the jaw bone. Axial, coronal, and sagittal images were reconstructed, and a panoramic image was further acquired from each scan by using Planmeca Dimaxis Pro software to get the precise data for analysis before and after surgery. Each patient was radiographically assessed by analysis of the bone height, and underwent simultaneous sinus lift without grafting materials and implant installation. 37 implants were inserted in total The clinical results after final restoration were evaluated.Results:The sinus membranes were successfully elevated without any iatrogenic perforation in 37 sites, which received final restorations at 6 months after surgery. 2 cases were found sinus mucosal hyperplasia. The success rate was 100%.Conclusion:CBCT can provide valuable data for determining the bone quality in maxillary posterior area of elderly patients with osteoporosis in treatment planning, as well as for the perioperative period of dental implant surgery and follow-up.
