This study presents a method to verify the position of dental implants after insertion without the repeated x-ray exposure.
An implant was inserted into the natural gap between the canines and premolars of 8 domestic pigs and 1 human patient. A scanbody was then connected to the implants and a digital intraoral impression of the jaw segment was acquired using a handheld scanner. In addition, the implant position was radiologically detected by cone beam computed tomography. The position of the implant based on both techniques was compared by digital matching.
The position of the dental implants determined by the scanner accurately represents the position in the radiograph in the pigs and also in the human patient.
Evaluating the position of implants using intraoral scans is a straightforward, accurate, and radiation-free method of 3-dimensional implant position determination.
本研究提出了一种在不进行反复X射线照射的情况下，验证牙种植体植入后位置的方法。
将一枚种植体植入8头家猪和1名人类患者犬齿与前磨牙之间的天然间隙中。然后将扫描体连接到种植体上，并使用手持式扫描仪获取颌骨节段的数字化口内印模。此外，通过锥形束计算机断层扫描对种植体位置进行放射学检测。通过数字匹配比较两种技术确定的种植体位置。
扫描仪确定的牙种植体位置在猪和人类患者中均能准确反映X线片中的位置。
使用口内扫描评估种植体位置是一种直接、准确且无辐射的三维种植体位置确定方法。
