Effect of progressive tissue contracture on functionality of obturator prosthesis: A 3-year follow-up

Objectives: This clinical report describes the long-term effect of tissue contracture on functionality obturator prosthesis. Material and Methods: Eleven patients who underwent maxillectomy confined only to hard palate rehabilitated sequentially with immediate surgical followed by interim closed bulb hollow were included in study. These up every 3 months for years prosthesis was relined at each appointment. All evaluated retention, resonating frequency, percentage nasality after wearing following relining till years. Results: At baseline, mean retention score ± SD (Median), % nasality, frequency 7.25 0.62 (7), 12.00 0.74 (12), 0.12 0.05 (0.115) kHz, respectively. During follow-up intervals, scores showed a gradual increase from 6-month itself (7.50 0.52) reached peak value 24 (9.17 0.83). With respect change different periods as compared declining trend observed first (6 months). continued subsequent intervals too values reaching their nadir 30 months. Conclusion: Literature regarding detrimental effects exists; however, little has been talked about beneficial role function. paper provides an insight usefulness related function retention.
