“…In the present study, masticatory ability was selfassessed by means of a questionnaire designed by Sato et al 11 They surveyed the clinical chewing ability of 110 CD wearers to validate the reliability and reported that the mean score of wearers who were satisfied was 58.7; partly satisfied, 48.5; and not satisfied, 32.4. These results suggested that the questionnaire corresponded closely to masticatory ability and was also useful for chair-side evaluation.…”

“…Masticatory ability was self-assessed by means of a questionnaire designed by Sato et al 11 The survey included questions on the chewing of the following 20 items arranged from easy-to hard-to-chew food: tofu, omelette, boiled potato, boiled carrot, bean sprouts, fish cake, potato chips, burdock, rice-cake cubes, roast meat, peanuts, pickled radish, hard cracker, hard rice cracker, cockle, hard pickled radish, dried squid, dried scallop, chewing gum, and whole apple. The subject was asked to classify each of the 20 food items as ''easy to chew'', ''difficult to chew'', or ''impossible to chew'' without exception.…”

Background: The purpose of this study was to investigate the differences in location of the main occluding area with reduction of occlusal support and to evaluate the subsequent impairment in masticatory ability. Methods: One hundred and two patients were recruited according to the Eichner's index, which is based on the number of occlusal support zones. Each subject was instructed to clench a piece of temporary stopping in the particular occluding area that was preferably used during mastication. The main occluding area was judged by locating the tooth on which the temporary stopping rested. Subjective masticatory ability was self-assessed by means of a questionnaire. Results: Group classification depending upon the location of the main occluding area was significantly associated with the category of the Eichner's index. The level of masticatory ability was significantly associated with the category of the Eichner's index. Moreover, masticatory ability was significantly more impaired in subjects with main occluding areas at the premolar regions compared to those at the molar regions. Conclusions: The location of the main occluding area may differ under the influence of the remaining natural teeth. The location of the main occluding area and the masticatory ability are likely to be closely related.

“…In terms of mastication disorder, the chewing score was 65%, and chewing function was judged to be level IV according to the Sato evaluation. 4 Teeth #11 and #45 were judged to be unsalvageable due to root fracture and irremediable caries, respectively.…”

A 66-year-old man visited our department with the chief complaint of poor esthetics due to loss of a fixed partial denture in a maxillary incisor tooth and difficulty in mastication due to an ill-fitting, mandibular removable partial denture. An analysis of the occlusal vertical dimension resulted in a diagnosis of infraocclusion. After increasing vertical dimension with a provisional restoration and treatment denture which covered the attritioned surface, a definitive prosthesis was applied. Untreated loss of molars and severe attrition of the remaining teeth caused infraocclusion in this patient, which increased occlusal loading on the incisor teeth and induced detachment of the prosthesis in the maxillary incisors. Esthetic appearance was improved and masticatory dysfunction restored by increasing vertical dimension and oral rehabilitation. Mildly invasive prosthetic treatment involved application of a removable partial denture which covered the attritioned surface, not only infraocclusion but masticatory dysfunction and poor esthetics were also treated.

“…On the other hand, the students surveyed the chewing function score, 11 and obtained VAS scale scores evaluating the esthetics and stability of RPDs. Both of them seem to be clinically acceptable and indicate that patients are willing to use students' RPDs.…”

In this study, we confirmed that the principle of rigid support was indispensable for RPD design from the evaluation of a clinical education program. On the other hand, we found out that an objective assessment of the educational system or RPD is necessary to improve the RPD clinical educational program. AbstractPurpose: The aim of this study was to survey the undergraduate removable partial denture (RPD) clinical program and RPD's fabricated by students in 2006, and to identify the problems to be solved in the future. Methods:Sixty-nine students in their final semester at Tokyo Medical and Dental University (TMDU) recorded the following preoperative data: age, gender, chief complaint, and Kennedy and Eichner classifications. The students were requested to present their treated cases and were subjected to an oral examination by the professor to determine the treatment plan and prosthetic design of denture. Additionally, the students surveyed the chewing function score and visual analogue scale (VAS) regarding esthetics and stability of RPD, and the material used for RPD frameworks was summarized. Results: The patients included 35 men and 34women, and their chief complaints were mostly dissatisfaction with their current dentures. More than 80% of cases were classified as Kennedy I or II, and about one-fourth were classified as Eichner B4 or C1, in which the occlusal supports could not easily be reconstructed. Chewing function score significantly improved compared to preoperative state (P<0.05) and postoperative VAS was clinically acceptable. 89% of frameworks, were cast with Co-Cr alloy in one piece and a palatal strap or bar and a lingual bar were applied in 77% of treated RPDs. Conclusion:It is thought that our educational methods for delivery of RPDs are adequate. Since it is suggested by an objective assessment of them that they are unsatisfactory, we should deal with that problem without delay.
