Bone grafting is often a prerequisite prior to implant placement. Studies evaluating the volume changes of block grafts in the incorporation phase mostly use methodologies that are difficult to apply when assessing large sample sizes. The aim of this study is to validate a new method for volume measurement of block grafts using CT scans for application on future research. Human bone blocks the were fixed with screws on dry skulls simulating a ridge reconstruction. The physical volume the blocks was determined by the water displacement technique and was used as the control group. A method previously described in the literature was tested using the Dicom Works© software. The new method proposed was performed using a tool of the Dental Slice© software. The volume of each block was automatically calculated by the software. The accuracy of each method was assessed using a paired Student’s t-test. There were no statistically significant differences between the methods and the control group. This novel method to three dimensionally measure bone blocks can accurately determine the volume of grafts for maxillary reconstruction. This method can be useful for future studies that aim to evaluate the remodeling of different types of block grafts. |
