title: Pre-operative measurement of the volume of bone graft in sinus lifts using CompuDent.
abstract: OBJECTIVE
  The aim of this study was to calculate the volume of graft necessary for rehabilitation using varying lengths of implants, and to evaluate the usefulness of the planning dental software in determining the pre-operative volume of bone graft in maxillary sinus floor lifts.
  
  
  METHODS
  Using the CompuDent program, we calculated the volume of graft necessary for 62 sinus lifts. This volume was measured to raise the floor of each sinus to 13.4 and 15 mm in height.
  
  
  RESULTS
  The average volume of graft to achieve a lift of 13.4 mm was 2.61 ± 0.69 cm³ for the right maxillary sinus, with the range of 1.38-4.1 cm³, and 2.68 ± 0.81 cm³ for the left maxillary sinus, with the range of 1.1-4.25 cm³. The average volume of graft to achieve a lift of 15 mm was 3.13 ± 0.75 cm³ for the right maxillary sinus, with the range of 1.59-4.81 cm³, and 3.29 ± 1.02 cm³ for the left maxillary sinus, with the range of 1.48-5.11 cm³. The statistical results showed a significant inversely proportional correlation between the average of the heights and the volume of graft in the right sinus.
  
  
  CONCLUSIONS
  The planning dental software is an effective tool in determining the volume of bone graft given the tool's simplicity, rapidness and possibility of standardization in all pre-surgical procedures.
