Effect of home reliner on occlusal relationships and oral mucosa: viscoelastic analyses by smoothed particle hydrodynamics simulation

Abstract

It was found that when an improper amount of HR was applied, the occlusal vertical dimension increased and the oral mucosa was pressured more than that under non-HR conditions.

Smoothed particle hydrodynamics method applied to oral region: A narrative review

“…Denture adhesives, soft relining materials, and tissue conditioners are used in removable dental prostheses. Given the effectiveness of the SPH method in analyzing soft materials, it was employed to assess the stress distribution on the mucosa in several studies 34,35) .…”

“…Hirayama et al created an SPH model of denture adhesive in a previous study 34) . This study aimed to analyze the displacement of dentures and the stress on the mucosa associated with the use of denture adhesive.…”

The potential effect of ethyl alcohol elution from liner type denture adhesives on breath alcohol concentration and determination of drunk driving

“…Liner type denture adhesives, namely, home reliners or cushion type denture adhesives, are designed to fill the gap between the intaglio surface of the denture and the basal seat mucosa by enhancing the fit. 8 , 9 , 12 , 13 , 14 Improper use of liner type denture adhesives may lead to absorption of the residual ridges. 15 , 16 The long-term use of such materials may cause the loss of flexibility and dimensional change, resulting in ill-fitting between the denture and mucosa and in instability of the dentures.…”

“…However, several researchers have reported that proper use of liner type denture adhesives reduces displacement and stress concentration on the basal seat mucosa, 13 , 17 , 18 reduces masticatory pain, 19 and improves masticatory function and patient satisfaction. 20 , 21 Furthermore, it has been reported that significant differences in satisfaction and functional outcomes were not found between maxillary complete dentures lined with liner type denture adhesives and those with tissue conditioners.…”

Influence of water immersion on the transmitted load of home reliners

“…By filling the gap between an ill-fitting denture and the denture-bearing mucosa, home reliners attenuate the pain caused to thin mucosa 1) . Previous studies have shown that the denture shift and the concentration of stress on the denture-base mucosa may be reduced by the appropriate use of home reliners 2,3) . Furthermore, several researches have shown that chewing ability and patient satisfaction levels are improved using home reliners [4][5][6] .…”
