动态导航系统 (DNS) 辅助提取受冲击的上前牙改善了外科手术的准确性. 与传统技术相比,这种方法提供了更高的精度和安全性.
科学领域:
- 口腔和牙面部外科手术
- 牙科技术 牙科技术
- 手术导航 手术导航
背景情况:
- 撞击牙的拔牙是具有挑战性的.
- 评估动态导航系统 (DNS) 对受冲击的上前牙的外科准确性至关重要.
研究的目的:
- 开发一种基于模型的协议,用于评估DNS辅助提取精度.
- 为了比较DNS辅助与传统方法的外科精度.
主要方法:
- 使用定制模型模拟受冲击的上上位牙.
- 术前规划整合了口内扫描和圆束计算机断层扫描 (CBCT).
- 通过DNS指导牙定位,骨切除和细分;通过术后CBCT通过3D偏差测量结果.
主要成果:
- DNS组在细分精度方面显示出明显较低的RMS偏差 (0.43 ± 0.18毫米对比0.85 ± 0.38毫米;P = 0.02).
- 较小的角偏差 (8.97°对比14.76°; P = 0.04) 和曲率RMS (1.72rad对比3.54rad; P = 0.04) 被观察到与DNS.
- 在DNS组中,最大偏差也明显较低 (0.77毫米对1.30毫米;P <0.01).
结论:
- 用DNS辅助的提取显著提高了受冲击的上前牙的外科准确性.
- 与传统方法相比,该技术提高了程序的准确性,稳定性和整体患者安全性.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
