“…Thus, prosthodontic output (as requested by dentists) of dental laboratories in Sofia indicates that dentists tend to provide fixed dental prostheses to restore incomplete dentitions to a functional level and not necessarily to complete dentitions. These findings are in line with contemporary treatment concepts, based on the assumption that reduced dentitions can offer sufficient oral function [14–16]. Moreover, it has been suggested that fixed rather than removable prostheses should be used even in elderly patients [17].…”

Objective. To describe prosthodontic production related to mutilated dentitions in Sofia, Bulgaria. Methods. Prosthodontic production from 5 dental laboratories was recorded during a 14-day period. Production was related to dentitions as noted from casts. Dentitions were classified as edentulous, interrupted/reduced, slightly interrupted, shortened, and complete. The representativeness of the laboratory sample was verified trough comparison with a Sofia population sample using proportions of crowned or replaced teeth per dental region. Results. The total production consisted of 243 crowns, 16 post and cores, 82 fixed dental prostheses, and 41 removable dentures. Proportions of crowned teeth were significantly different between the samples; proportions of replaced teeth were not. Of the 58 incomplete dentitions analyzed, 19 were restored to the level of completeness, 15 resulted in slightly interrupted, and 24 in shortened dentitions. Conclusions. Predominantly fixed restorations were provided to restore mutilated dentitions to a functional level and not necessarily to complete dentitions.

The purpose of this study was to determine how elderly Japanese people subjectively value treatment options for missing molars. Subjects were 528 independently community-dwelling elderly people. They were presented with photographs and descriptions of the process and expected outcomes of five possible treatment options: cantilever fixed dental prosthesis (FDP); resin or metal removable partial denture prosthesis (RPDP); implant-supported fixed prosthesis; and no replacement (shortened dental arch: SDA) for missing lower bilateral first and second molars. The participants filled in the questionnaire on subjective importance for treatment and indicated on a visual analogue scale how they valued the treatment (utility value: UV). Values were analysed by Mann-Whitney U-tests and multiple logistic regression analyses. Overall, the UVs for the FDP and the metal RPDP were the highest, and the UV for the SDA was the lowest. With respect to subjective importance, 'chewing ability' and 'no pain during function' were significantly selected more frequently. Multiple logistic regression analyses showed that the UV for the resin RPDP had significant positive associations with denture wearers and low treatment cost, whereas the implant had significant negative associations with denture wearers and older age. The SDA had significant positive associations with men and low treatment cost and a negative association with appearance. In conclusion, these elderly Japanese preferred cantilever FDPs and metal RPDPs to implants and 'no replacement.' It suggests that the SDA as an oral health goal can be questionable from the patients' point of view, even if it is biologically correct.

“…The concept of the shortened dental arch (SDA) has been developed as a treatment option for partially edentulous individuals. 1,6,12 There is consensus that ten pairs of teeth are required in occlusion (20 teeth distributed from the 2 nd premolar to the 2 nd premolar in both arches). According to Witter et al, 26 a SDA with three to fi ve occlusal units or functional posterior occluding pairs (POPs), with or without free-end removable partial dentures, provides suffi cient occlusal stability for a prolonged period of time.…”

OBJECTIVE:To describe the distribution of edentulism and estimate the prevalence of functional dentition and shortened dental arch among elderly population. METHODS:A population-based epidemiological study was carried out with a sample of 5,349 respondents aged 65 to 74 years obtained from the 2002 and 2003 Brazilian Ministry of Health/Division of Oral Health survey database. The following variables were studied: gender; macroregion of residence; missing teeth; percentage that met the World Health Organization goal for oral health in the age group 65 to 74 years (50% having at least 20 natural teeth); presence of shortened dental arch; number of posterior occluding pairs of teeth. The Chi-square test assessed the association between categorical variables. The Kruskal-Wallis and Mann-Whitney tests were used to assess differences of mean between number of posterior occluding pairs teeth, macro-region and gender. RESULTS:The elderly population had an average of 5.49 teeth (SD: 7.93) with a median of 0. The proportion of completely edentulous respondents was 54.7%. Complete edentulism was 18.2% in the upper arch and 1.9% in the lower arch. The World Health Organization goal was achieved in 10% of all respondents studied. However, only 2.7% had acceptable masticatory function and aesthetics (having at least shortened dental arch) and a mean number of posterior occluding pairs of 6.94 (SD=2.97). There were signifi cant differences of the percentage of respondents that met the World Health Organization goal and presence of shortened dental arch between men and women. There were differences in shortened dental arch between macroregions. CONCLUSIONS:The Brazilian epidemiological oral health survey showed high rate of edentulism and low rate of shortened dental arch in the elderly population studied, thus suggesting signifi cant functional and aesthetic impairment in all Brazilian macroregions especially among women.
