Statement of problem: The recording of vertical jaw relation in the treatment of edentulous patients aim at facilitating the adaptation of complete dentures to the masticatory system to give them an optimal and comfortable function. There are various techniques described in the literature to record vertical jaw relation, but there is a need to intercompare these methods based on patient’s acceptance. Aim: To determine the efficiency of different method to establish vertical dimension at occlusion comparing three conventional methods and analyzing patients acceptance of these   respective   methods. Methodology: ten completely edentulous subjects, each of three groups which includes methods to record vertical jaw relations (physiological method, phonetics and swallowing threshold) on patients between age group of 45-60 years were selected for the study. Vertical dimension at rest and at occlusion were determined by operator1(OP1-prosthodontist. After each recording, operator-2 (OP-2 patient &, or person accompanying patient) was asked about the appearance, which one was better to  look at, and the comfort and this clinical acceptance was recorded  on a scale from 1 to 3  by both Operator and the patient. Student’s paired t-test was used to know whether there was any statistically significant difference between two independent sample means with Significance tested at  1% level of confidence (p<0.01). Results: It can be concluded from the study that, statistically the mean values of swallowing threshold (OP I – 1.5000, OP II – 2.200) significant compared to the values of physiologic rest position (OP I – 2.90, OP II – 2.84) and phonetic method (OP I –1.80, OP II –2.51). Conclusion: Swallowing threshold was acceptable to both operator and the patient, as statistical significant difference was found with the vertical dimension values obtained by other two methods. Therefore it is suggested that swallowing threshold method may be employed for establishing vertical dimensions, however other two methods must be used for evaluation of vertical dimension and interocclusal distance.
Keywords: freeway space, vertical dimension at rest, vertical dimension at occlusion.
