Abstract
This study evaluated the advantages of computed tomography (CT) in comparison to routine panoramic radiography for dental implant treatment planning. An in vitro validation study was performed to assess the accuracy of CT and panoramic radiography film images for measurement of anatomic structures and distances between anatomic structures. After correcting by a standard 25% magnification on the panoramic images, a significant difference in measurements was found between the CT and panoramic radiography images. Ten subjects requiring implants in compromised ridges were treatment planned with either CT and panoramic radiographs or panoramic radiographs alone. The ideal implant length was determined at surgery with direct digital radiography. The dentists were significantly more confident using CT and panoramic images than panoramic radiographs alone. Implant length treatment planned with panoramic radiography alone underestimated length significantly compared with the implant length determined to be ideal during surgery.whereas treatment planning with CT and panoramic radiography demonstrated no significant difference. The data indicate the CT may be of value in treatment planning for dental implants, especially when gaining maximum length is of critical importance.
