Caries incidence following restoration of shortened lower dental arches in a randomized controlled trial

Abstract

Two years after restoration of lower shortened arches for an elderly sample of patients, there was a significantly greater incidence of new and recurrent caries lesions in subjects restored with RPDs compared with cantilever RBBs.

A systematic review of prosthetic restoration in patients with shortened dental arches

“…Two RCTs found that caries developed more frequently after treatment with RPDs compared to CFPD treatment [35,39]. Gingival inflammation and plaque accumulation on abutment teeth of RPDs were higher than those of CFPDs 2 and 5 years after treatment, while probing pocket depth, tooth mobility and alveolar bone height were almost identical for both treatments [40,41].…”

“…However, there was no statistically significant difference in the patient satisfaction between patients with RPDs and those with CFPDs [36]. An RCT found that OHRQoL improved after treatment with RPDs, while no statistically significant difference was found between patients with RPDs and those with CFPDs due to small sample size [33].…”

“…An RCT reported that treatment with RPDs improved patient satisfaction in terms of chewing ability and oral comfort [36]. However, there was no statistically significant difference in the patient satisfaction between patients with RPDs and those with CFPDs [36].…”

Association of removable partial denture use with oral and systemic health

“…62,64 In a randomised controlled trial that compared the use of RPDs or single pontic cantilever resin-bonded fixed partial dentures to restore severely shortened mandibular arches, there were significant improvements in satisfaction scores for both treatments but a larger clinical effect for the fixed partial denture group. 65 In a somewhat underpowered cross-sectional study, it was found that patients with shortened dental arches only perceived a benefit of RPD provision to their quality of life if the RPD included replacement of missing anterior teeth. 66 There was no perceived benefit from the use of RPDs if only posterior teeth were replaced.…”

Influence of molar support loss on stress and strain in premolar periodontium: A patient-specific FEM study

“…The effect of molar support loss on the migration of the remaining teeth, 1,2 possible interactions with temporomandibular disorders, 3,4 and chewing functions 5,6 has been assessed extensively. The results of these studies generally suggest that, following the loss of molar teeth, an initial, minor migration of the remaining teeth may lead to a new occlusal equilibrium.…”
