A Retrospective Evaluation Of Various Methods To Determine Vertical Loss In Full Mouth Rehabilitation Patients

The aim of this study was to retrospectively evaluate the commonly used technique for evaluating vertical dimension loss in patients who are required for full mouth rehabilitation among dental students. A total of 145 data entries were taken after reviewing 86000 patient data, duplicate and missing entries were omitted. So a total of 114 entries were evaluated. The data was collected from patient records in Saveetha Dental College, over a period of one year. The evaluation was based on the technique used by the dental students, to measure the loss of vertical dimension. The results of the study were subjected to statistical analysis. Data analysis was done using SPSS software version 23.0.Chi-square test and frequency evaluation was done to evaluate the most frequently used method to record vertical loss. It was found that about 93.3% of students have used the Niswonger and Thomson method and 6.7% have used the Tactile perception method although found to be statistically not significant. Pearson (Chi-Square Value - 8.559 and p-value - .638) (p>0.05)The present study concluded that most of the dental students preferred Niswonger and Thomson method for determining loss of vertical dimension.
