Hypothesis
If the difference is small, our method is comparable to that proposed by Čobeljić et al.
Conclusion
Our ruler is convenient for practical use for the rotational osteotomy procedure with equal precision.
Supporting Evidence
- The error of Čobeljić et al. is between -37% to 16% (mean ± SD = -6% ± 9%).
- The absolute difference between both methods ranges from 0 to 0.1 mm with a mean ± standard deviation (SD) of 0.03 ± 0.05 mm.
- Our ruler can be made of paper or stainless steel and used after sterilization.
Takeaway
The researchers created a small ruler to help doctors perform a surgery called rotational osteotomy more easily and accurately.
Methodology
The study involved developing a small ruler based on a four-page numeric table method and verifying its accuracy through computer modeling.
Limitations
Further clinical verification is needed to justify its real significance.
