Abstract
The aim of this study was to examine the designs and performance of maxillary complete dentures in patients with torus palatinus. Maxillary impressions of one hundred and fifty patients with torus palatinus were taken and study casts were obtained using yellow stone (Calstone, France). The size of torus palatinus for individual cast was measured using MyCast (patented at Universiti Sains Malaysia) and Australis software, Version 6.01 (Photometrix, Australia) and graded into slight, moderate and marked size. Patients with slight, moderate and marked torus palatinus who were wearing maxillary complete denture were called for an appointment (n=20 patients for each group). The designs (full coverage or horse-shoe) of the patient‟s maxillary complete dentures were examined and recorded. In addition, the dentures were examined for its retention and stability using National Health and Nutrition Examination Survey (NHANES III, examination and adult data files, 1988-1994). The patient‟s satisfaction upon wearing the denture was also assessed using a validated questionnaire. Data was entered into SPSS software and analyzed using chi-square test whereby results with p<0.05 was considered statistically significant. This study found that the mean for length, width and height of the torus palatinus were (23.18 mm ± 3.78), (14.84 mm ± 1.61) and (3.53 mm ± 1.32) respectively. Among 150 patients, 71 (47.3%) slight, 59 (39.3%) moderate and 20 (13.3%) marked size torus platinus were found. Fourty three male patients (28.7%) and 107 (71.3%) female patients with torus palatinus were also recorded. The male to female ratio was 1:2.5. Torus palatinus was most commonly found in 40-59 years of age. Among 60
patients with different sizes of torus palatinus, 24 horse-shoe and 36 full coverage denture designs were found. 38 patients were wearing retentive denture while 22 patients were having non retentive denture. Moreover, 37 patients with stable dentures and 23 patients with unstable dentures were found in the present study. Satisfaction of wearing maxillary denture was commonly found in slight and moderate size compared to marked size torus palatinus patients.
