Abstract

pose of this study was to clinically assess relationship between freeway space (FWS) and
occlusal schemes, overjet, overbite and wear facets. Methodology: 60 subjects fulfilling the inclusion
criteria within the age range of 20-40 years were included in the study. Vertical dimension at rest (VDR) and
occlusion (VDO) were measured with digital vernier calliper. Lateral occlusal scheme was examined
intraorally. Overjet-overbite were measured at mandibular right central incisor on dental casts. Data were
analysed statistically using chi square test (Ï‡2) and Pearsonâ€™s correlation (r). Results: A significant
association was observed between FWS and occlusal scheme. Group function occlusion was found in 18 out
of 26 subjects with FWS<2mm, whereas canine guided occlusion was found in 20 out of 30 subjects with
FWS of 2-4mm. A significant positive correlation was observed between FWS and anterior overjet. Presence
of occlusal wear facets was found in 20 out of 26 subjects with FWS< 2mm whereas in subjects with
FWS=2-4mm, 8 out of 30 subjects showed presence of occlusal wear facets. Conclusion: Group function
occlusion scheme and an increase in occlusal wear facets were found more prevalent when FWS was less
than 2mm. An increase in FWS resulted in an increase in overjet. [Mehta S Natl J Integr Res Med, 2019;
