Abstract

Objectives:
Panoramic
radiography (PR) is the most commonly used technique to evaluate the dental and
associated structures. The aim of this study was to determine the accuracy of
panoramic radiographs (PRDs) in planning of dental implant treatment and the
magnification rate of a panoramic device for anterior, premolar and posterior
regions.

Materials and Methods: Eighty-eight patients, who received PRD after implant surgery, were
included to the study. A total of 240 dental implants (53 anterior, 69
premolar, and 118 molar regions) of which previously vertical lengths were
known, were re-measured on post-operative radiographic images using the scaling
tools of the panoramic system to determine the magnification rate and the
accuracy of PRDs.  Cause the data had
normal distribution, the paired t test was used for the statistical analysis
(p<0.05). The magnification rate of the three regions was calculated as the
rate of measured vertical length of the implants to the actual vertical length
of the implants.

Results: Statistically
significant difference was found between the actual and measured vertical
length of the implants on the PRD (p<0.05). However, the correlation rate
was found close to 1 for all regions. 
The difference between the actual and measured vertical length of the
implants on the PRD was 0.50 mm for the anterior region, 0.97 mm for the
premolar region, and 0.83 mm for the molar region. The magnification rate of
the panoramic system corrected by Cliniview^TM (Instrumentarium
Corp., Tuusula, FINLAND) software was found around 1 for all the regions.

Conclusions: Due to their readily accessible nature and low radiation dose, PRDs can
be used in implant surgery for vertical measurements with 1 mm confidence
interval.
