Abstract

Background: One of the main uses of CBCT is the design of implant therapies, and linear calculations in these therapies are important in quantifying bone (height and width). However, previous researches have all been conducted on dry skulls and no research has been performed in patients' clinical conditions.

Aim of the Study: The aim of this research was to determine the correlation between CBCT linear measurements and actual measurements during surgery in patients undergoing implant surgery.

Materials and Methods: In diagnostic research, 54 patients were selected for implant treatment in the premolars and the distance of the mental foramen to the apex of the ridge was measured using a caliper during surgery. The same calculations were repeated in CBCT images with Romex is software by two observers at two 2-week intervals. The difference in bone height calculations in CBCT images and actual measurements during surgery were analyzed by repeated values and ANOVA.

Results: The difference in absolute value of bone height in CBCT images (second observer) and its actual values was 0.811 ± 0.54, 0.894 ± 0.67 between the first observer and its actual values,0.871 ± 0.63 between the first observer in the next 2 weeks later and the actual values,0.804 ± 0.57 between second observer in 2 weeks later and its actual values. The mean difference of bone height observations by 2 observers in 2 weeks from its actual values was equal to 0.0 ± 828.89 mm. No significant differences were observed between the absolute magnitude values of bone height measurements in CBCT images and their actual values at the time of surgery after exposure.

Conclusion: Given the limited bone height difference in CBCT images from its actual values, this imaging modality appears to be a useful and accurate tool for estimating bone height in implant surgery in clinical settings.
