To evaluate the 3-dimensional features of the grafted bone with maxillary sinus augmentation and to assess the relation
between the degree of bone resorption and the type of bone grafting source and implant, and the operation method. A
retrospective chart review of patients receiving sinus augmentation procedures for implant positioning was conducted:
radiographic analysis of the volume and area of bone grafts was performed. The volumetric remodeling?measured at 6
months after implant positioning as the percentage of residual bone graft?was correlated to type of graft materials and
operation methods. 53 dental implants positioned with sinus bone graft in 15 patients at Wonkwang University Sanbon
Dental Hospital. Computed tomography scans,taken implant positioning after 6 months, showed greater resorption values
for the group of Puros¨Þ graft alone from the group of mixed with Puros¨Þ and various bone graft (P<0.05, respectively).
And resorption values according to operation methods have statistically significant difference(P<0.05). Volume change ratio
of bone graft showed greater values for the group of delayed implant position from the group of simultaneously implant
placement with bone graft. Retrospective data analysis shows that the method of graft with Puros¨Þ alone may occur greater resorption of graft materials than mixed graft material with Puros¨Þ and other graft materials. The group of simultaneously implant placement with bone graft also display smaller resorption ratio of bone graft than the group of delayed implant placement.
