A computer-assisted measurement technique to assess bone proximal to oral implants on intraoral radiographs

A computer-assisted measurement technique for measuring bone levels proxima l (mesial and distal) to oral implants imaged on standardized intraoral rad iographs offers promise for accuracy and reliability. There were no differe nces between bone measurements made directly from bone proximal to implants placed in a dry mandible and those resulting from the computer-assisted me asurement technique. In addition, there were no differences between measure ments made of bone proximal to oral implants in vivo using the microscope a nd the computer techniques. The computer technique had a low intra- and int er-operator variability, and operators found fewer "unreadable" sites compa red to the microscope technique. The computer-assisted measurement of bone levels proximal to oral implants on standardized intraoral radiographs offe rs accuracy and reliability.
