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.
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.
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.
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.
本研究旨在计算使用不同长度种植体进行修复所需的移植物体积，并评估规划牙科软件在确定上颌窦底提升术中骨移植术前体积方面的有用性。
使用 CompuDent 程序，我们计算了 62 例鼻窦提升所需的移植物体积。为了将每个窦腔的底部抬高到 13.4 和 15 毫米的高度，我们对该体积进行了测量。
为了实现 13.4 毫米的提升，右侧上颌窦的平均移植物体积为 2.61 ± 0.69 cm³，范围为 1.38-4.1 cm³，左侧上颌窦的平均移植物体积为 2.68 ± 0.81 cm³，范围为 1.1-4.25 cm³。为了实现 15 毫米的提升，右侧上颌窦的平均移植物体积为 3.13 ± 0.75 cm³，范围为 1.59-4.81 cm³，左侧上颌窦的平均移植物体积为 3.29 ± 1.02 cm³，范围为 1.48-5.11 cm³。统计结果显示，右侧窦平均高度与移植物体积之间存在显著的负相关关系。
规划牙科软件是一种有效的工具，可以确定骨移植的体积，该工具具有简单、快速和标准化所有术前程序的可能性。
