Subjective assessment of chewing function of Obturator prosthesis wearers.
The International journal of prosthodontics, 2007Co-Authors: Miwa Matsuyama, Yoshihiro Tsukiyama, Mikiko Tomioka, Kiyoshi KoyanoAbstract:Assessments of masticatory performance and occlusal force for wearers of Obturator prostheses were performed as clinical objective assessments and reported in an earlier study. The purpose of the present study was to evaluate clinically the chewing function of Obturator prosthesis wearers by self-evaluations and to examine their relationship to the objective assessments. Twenty patients with Maxillofacial Obturator prostheses who were having a periodic checkup at the Maxillofacial rehabilitation clinic in Kyushu University Hospital were recruited for this study. Chewing function was evaluated by 3 assessment tools: a self-assessment mastication scale, a chewing function score, and a mastication score. In addition, correlations among these assessments and objective tests--ie, masticatory performance and maximum occlusal force--were analyzed by the Spearman rank correlation coefficient. The mean self-assessment mastication scale was 63.2 (SD 31.8), the chewing function score was 54.0 (SD 30.2), and the mastication score was 51.4 (SD 33.3). There was no statistically significant relationship between the self-assessment mastication scale and each objective test. However, there were significant correlations between each semisubjective score--the chewing function score and the mastication score--and masticatory performance. There was no relationship between each semisubjective score and maximum occlusal force. A self-assessment mastication scale was not always in agreement with objective assessments, and assessments made by patients should be taken into consideration when arranging Maxillofacial rehabilitation. Conversely, both chewing function and mastication scores corresponded with masticatory performance, and these would be useful as screening tests before performing objective tests.

Clinical assessment of chewing function of Obturator prosthesis wearers by objective measurement of masticatory performance and maximum occlusal force.
The International journal of prosthodontics, 2006Co-Authors: Miwa Matsuyama, Yoshihiro Tsukiyama, Mikiko Tomioka, Kiyoshi KoyanoAbstract:Eating, which includes chewing and swallowing, is an oral function that influences quality of life. Though the swallowing ability of maxillectomy patients was reported in our previous study, the chewing function has not been fully reported to date. Thus, the purpose of this study was to evaluate the chewing function of Obturator prosthesis wearers by measurement of masticatory performance and occlusal force. The relationship of these 2 measurements was also investigated. Twenty Maxillofacial Obturator prosthesis wearers undergoing periodic checkup at the Maxillofacial rehabilitation clinic in Kyushu University Hospital were recruited for this study. Additionally, 20 young, healthy individuals were recruited as controls. Data on masticatory performance, which was measured by a sieve method using hydrocolloid material, and maximum occlusal force, which was measured by the Dental Prescale System (Fuji Film), were obtained for each participant. The mean of masticatory performance was 2.6 (SD 1.2) on a 1.40-mm mesh. There was no significant difference in masticatory performance between the patient group and the controls. The mean maximum occlusal force of the patient group was 625.9 N (SD 299.1 N), which was significantly lower than that of the control group. There was no significant correlation between masticatory performance and maximum occlusal force for the patient group in this study (P = .3726). Masticatory performance of Obturator prosthesis wearers with dentate or partially edentulous maxillae was not different from that of young, healthy individuals, though maximum occlusal force of these patients was lower than that of controls.

Evaluation of the speech outcomes in patients with unilateral maxillary defect rehabilitated with maxillary Obturator prosthesis
Shanghai kou qiang yi xue = Shanghai journal of stomatology, 2005Co-Authors: Guo-fang Xing, Jian Sun, Ting Jiao, Yong-lin JiangAbstract:Evaluation of the outcomes in 15 patients with unilateral maxillary defect before and after Maxillofacial Obturator prosthesis. 15 patients with unilateral maxillary defect were included in this study, who received Obturator prosthesis for maxillary rehabilitation. The pronunciation of the examined phonetics such as /a/, /o/, /e/, /i/, /u/ were transferred into CSL4400 before and after treatment. The mean value of the first, second, third formant were measured. Paired t test of SPSS11.0 was used for statistical analysis. There was statistically significant difference on F2 and F3 before and after treatment (P<0.05). After treatment the value of F3 was increased significantly. The soft palate was reconstructed after Obturator treatment. The space between the nasal and oral cavity was sealed,through which a similar normal oral cavity was obtained. Except F1, F2 and F3 of all the vowels changed after treatment. Maxillofacial prosthesis can improve the speech function of patients with unilateral maxillary defect effectively.
