summary 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.
