Abstract

Objective: To evaluate the tongue pressure exerted on the loop of transpalatal arch in different craniofacial patterns at different heights from the palatal mucosa.
Material and Method: 15 subjects were divided into three groups according to Schudy’s facial divergence angle as: Group I (Normodivergent), Group II (Hypodivergent) and Group III (Hyperdivergent). TPA was fabricated and placed at 2mm, 4mm and 6mm heights from the palatal mucosa in each subjects and tongue pressure was measured during swallowing using pressure sensors placed on the loop of TPA. The data obtained were recorded and subjected to statistical analysis.
Result: On intergroup comparison, maximum tongue pressure was found in Group III followed by Group I and Group II and the difference was statistically significant (p<0> by 4mm and 2mm in each group and difference was statistically significant (p<0> Conclusion: The maximum tongue pressure was observed in Hyperdivergent and minimum in Hypodivergent craniofacial pattern. It increases as the distance of the TPA from the palatalmucosa increases in all craniofacial patterns.
