Dimensión vertical oclusal: comparación de 2 métodos cefalométricos

Objective

The purpose of this study was to compare the Occlusal Vertical Dimension (OVD) determined with the “Knebelman Craniometric method” and with the “Willis method” on the same patient.

Material and method

The study was conducted on a sample of 74 subjects with their full dentition. The mean age was, They were students of fourth year, with a mean age of 22 years ± 0.99, from the Faculty of Dentistry at Mayor University. The measurement instruments used were the Knebelman Craniometer and the Willis Device. They were used according to the methodology recommended by their manufacturers. The results were analysed using the Paired T-test, with the OVD determined by each method expressed in millimetres.

Results

No significant differences were found when comparing the OVD determined using the Knebelman Craniometer and the Willis Device on the same patient (mean difference of 0.7 mm between both methods).

Conclusion

There were no significant statistical or clinical differences between both studied instruments. In this context complementing with both instruments, the Knebelman Craniometer and the Willis Device, could be a valuable tool to fine-tune and simplify the measurement of OVD in edentulous patients.
