“…The RPDs have been reported to lead to increased plaque accumulation, mainly on tooth surfaces in contact with the denture (33, 34), but also on other tooth surfaces (35, 36). In one clinical study (3), patients wearing RPDs were reported to have experienced more harmful effects on periodontal tissue when compared with controls; however, the authors noted that the oral hygiene of patients in the study was less than optimal, as they were not seen at regular intervals by the same examiners and received no reinforcement of oral hygiene instruction.…”

A 30-month follow-up study was conducted on 36 patients to evaluate the effects of the lingual plate as a major connector in distally extended removable partial dentures (RPDs) on tooth stabilization. At the same time, the study evaluated the effects of lingual plate-type RPDs and lingual bar-type RPDs on periodontal health. The most striking finding of the study was that, with the exception of gingival recession (GR), periodontal conditions improved with both types of RPDs. At the end of 30 months, there were significant differences in plaque index, GR and tooth mobility (TM) values between treatment groups (P < 0.05). Plaque accumulation was greater in the lingual plate treatment group; however, this did not result in periodontal breakdown. There were no statistically significant differences between treatment groups with respect to pocket depth, gingival index or attachment loss (P > 0.05). Moreover, patients treated with lingual plate-type RPDs demonstrated less TM when compared with patients treated with lingual bar-type RPDs at the end of 30 months follow-up. Overall study findings established that with adequate checks on oral and denture hygiene at regular intervals, patients with RPDs may even experience improved periodontal health. Moreover, the clinical interpretation of decreased TM observed in patients treated with lingual plate-type RPDs may be questionable as the plaque accumulation was greater in the lingual plate treatment group inspite of periodic recalls.

Physico-mechanical properties and prosthodontic applications of Co-Cr dental alloys: a review of the literature

Cobalt-Chromium (Co-Cr) alloys are classified as predominantly base-metal alloys and are widely known for their biomedical applications in the orthopedic and dental fields. In dentistry, Co-Cr alloys are commonly used for the fabrication of metallic frameworks of removable partial dentures and recently have been used as metallic substructures for the fabrication of porcelain-fused-to-metal restorations and implant frameworks. The increased worldwide interest in utilizing Co-Cr alloys for dental applications is related to their low cost and adequate physico-mechanical properties. Additionally, among base-metal alloys, Co-Cr alloys are used more frequently in many countries to replace Nickel-Chromium (Ni-Cr) alloys. This is mainly due to the increased concern regarding the toxic effects of Ni on the human body when alloys containing Ni are exposed to the oral cavity. This review article describes dental applications, metallurgical characterization, and physico-mechanical properties of Co-Cr alloys and also addresses their clinical and laboratory behavior in relation to those properties.

Bergman B, Ericson G: Cross-sectional study of padents treated with removable partial dentures with special reference to the caries situation. Scand J Dent Res 1986; 94: 436-42.Abstract -Thirty-four padents provided with removable partial dentures (RPDs) were reexamined after 3 yr. Garies that had developed during the period were analyzed with regard to the following potential caries risk factors: Lactobacilli, Streptococcus mutans, flow rate and buffer pH of paraffin stimulated saliva, oral hygiene and daily sucrose intake. Of 436 initially intact surfaces 31 (7.1%) had decayed and/or were restored during the 3-yr period. Caries recurred in 26 (6.2%) out of 422 initially restored surfaces during the same period. The development of new or recurrent caries had no correlation to whether or not the surfaces affected were in contact with the RPDs. No single caries risk factor seemed to he sufficiently closely correlated to the number of caries lesions developed to be used alone in the selection of patients at risk. When the sum of assumed negative factors was used a correlation was found for the group as a whole hetween the number of negative factors and the development of caries. However predicting the development of caries in any individual case seems to be more complicated.
