Studies in Partial Dental Prosthesis iv. Final Results of a 4-year Longitudinal Investigation of Dentogingivally Supported Partial Dentures

The aims of the study were to determine the periodontal status of the teeth in contact with removable partial dentures (RPDs) and to compare them with other teeth in the opposing arch not related to any prosthesis. The periodontal status was also assessed in relation to the age of the dentures. Four hundred and twenty-seven patients treated with RPDs from 1981 to 1986 were recalled for examination. Prior to prosthetic treatment they were given periodontal treatment and fillings when required. Initially all were given oral hygiene instructions and motivation. They were reviewed regularly only on a short-term basis. Eighteen patients were suitable for the present study comprising of eight males and 10 females whose mean age was 41 years. The RPDs were in use from 1.5 to 8 years (mean 4.6 years). The following parameters were assessed: Plaque index (P1I), Gingival index (GI), loss of attachment (LA) and tooth mobility. The wearing of RPDs resulted in higher P1I, GI and LA compared to the controls and these differences were statistically significant. There was an increased frequency of higher P1I, GI and LA with the increase in denture age. Minor changes in tooth mobility were observed. It was concluded that the wearing of RPDs was detrimental to periodontal health in patients whose oral hygiene was less than adequate.

Periodontal status of teeth in contact with denture in removable partial denture wearers

1994

“…Removable partial dentures, if optimally constructed, can be well tolerated by patients (Carlsson, Hedegard & Koivumaa, 1965;Bergman, Hugoson & Olsson, 1971). Such prosthetic appliances can, however, not be used in situations where several or all abutment teeth have excessive mobility related to extensive bone loss.…”

“…The 100 kg fork was used for maximum registrations exceeding 25 kg. The apparatus has been described elsewhere (Carlsson, Helkimo & Helkimo, 1971). Registrations were made in the most distal part of the dentition, in the region of the central incisors and in the canine regions.…”

The present study examines the function of fixed bridges on abutment teeth with reduced but non-inflamed periodontal tissues. Eighteen patients with advanced periodontal breakdown and indication for oral rehabilitation received periodontol treatment and their dentitions were restored with fixed bridgework. The analysis of function performed 2-5 years after insertion of the reconstructions was made by (1) evaluation of the patients' opinion on chewing ability and function of the masticatory system; (2) clinical examination of the border movements of the mandible, the status of the temporomandivular joints and the chewing muscles, and (3) measurements of the bite force indifferent areas of the dentition. The results of the study show that the functional capacity of the type of extensive bridgework discussed is good and that the patients--in spite of severe loss of periodontal tissue--achieve bite force values that are almost comparable to those in individuals with natural teeth. Comparison of the function of fixed bridges and that of removable dentures is also discussed.

“…Studies have shown that partial dentures in the mouth increase plaque formation, (Bates & Addy, 1978;Bergman, 1987;Kratochvil, Davidson & Guijt, 1982;Schwalm, Smith & Erickson, 1977;Brill et al, 1977) particularly on tooth surfaces in contact with the partial denture (El Ghamrawy, 1976). An increase in caries has been reported in partial denture wearers (Carlsson, Hedegard & Koivumaa, 1965) and in a study by Bergman and Ericson (1986), 64-5% of the incidence of new caries and 88-5% of recurrent caries occurred on abutment teeth. There are studies, however, that do not support the hypothesis that removable partial dentures increase the likelihood of caries development (Bergman, Hugoson & Olsson, 1977).…”

The oral status of elderly removable partial denture wearers

Drake

Beck

1993

A random sample of 1019 elderly home dwelling persons participated in this study. There were 809 dentate respondents, 28.6% of whom wore removable partial dentures. They were examined for coronal and root caries, gingival recession, pocket depth and loss of gingival attachment. The removable partial dentures were also evaluated. Abutment teeth were found to be more likely to have caries and periodontal disease than all other teeth. Using a MANOVA statistical procedure, the analysis indicated that the partial denture itself, irrespective of any professionally determined problems with the denture, appears to affect coronal and root caries on the teeth of partial denture wearers. Partial dentures judged to need repair or adjustment were related to periodontal status. The data on adverse effects of partial dentures suggest a need for patient education by the dentist and through public health measures, and good oral self care and regular professional recall for people who wear removable partial dentures.
