Abstract

Abstract: Objective To evaluate the effects of anatomical factors (sinus cavity width, sinus cavity angle, and sinus floor morphology) on the reconstruction of bone graft materials for transalveolar technique for sinus floor elevation. Methods A total of 36 implant sites in 23 patients were included to analyze the changes in bone height and bone density at 6 months and immediately after surgery, and to evaluate the effect of anatomical factors of maxillary sinus on bone graft material modification in the maxillary sinus. Results The sinus cavity width, sinus cavity angle, and sinus floor morphology (intruding angle) were significantly positively correlated with bone height changes, P<0.01. Sinus floor morphology (intruding angle) was negatively correlated with changes in bone density around the implant, P<0.05. There was no significant correlation between RBH and bone graft material reconstruction, and different contact numbers of the bone walls had no significant effect on bone graft material reconstruction. Conclusion There was a correlation between the anatomical factors of the maxillary sinus and the reconstruction of bone graft materials in the maxillary sinus, and the anatomical morphology of the maxillary sinus should be carefully evaluated before surgery.
