Evaluate and measure the changes in retention of mandibular denture by determining the effect of tongue movement on depth & width of anterior lingual flange

Abstract

Abstract

Background:    To evaluate the changes in retention of mandibular denture by determining the effect of tongue movement on depth & width of anterior lingual flange.

Materials & Methods:A total of10 healthy male and female edentulous subjects werechosen from the outpatient department. The mean age was 59.58 years. A two-tailed test was used for data obtainedby measuring vestibular depth and width at five different locations from the center of crest using periodontal probe and boley’sguageand, the testing apparatus was used to measure magnitudeof forces required to dislodge the denture bases. The result was analysed using SPSS software.

Results:The conventional border molding technique was used for the patients and range of meandepth of alveolo-lingual sulcus was 1.5 mm to 5.5 mm with standard deviation of ± 0.48210, indicating statistically significant result in retention, mean vestibular depth and width of denture bases after conventional border molding

Conclusion: There is a significant change in the retention of mandibular denture and, also on the depth and width of anterior lingual flange by asking the patient to do wide range of tongue movements. Thus, it’s very important to make the patient do the right tongue movements for recording anterior lingual space to provide seal for better retention and stability of lower denture during functional movements.
