At 6-month follow-up examination (T6), the mobility of the removable partial denture (RPD) abutment tooth (PTV) in intervention group was significantly lower than that in control group. PTV was significantly lower at T6 than that at baseline (T0) in intervention group. It can be concluded that a night denture placement might inhibit the increase in mobility of RPD abutment teeth and be effective in protecting them in RPD wearers with sleep bruxism.

Removable partial denture (RPD) wearers with a diagnosis of sleep bruxism (SB) using a miniature electromyogram device (BiteStrip).
The candidates for this trial were removable partial denture (RPS) wearers who visited the Tokyo Medical and Dental University (TMDU) Dental Hospital. The inclusion criteria were as follows: classified B2-B4 based on the Eichner classification, continuous use of RPD(s) for at least 1 month, and reasonable oral hygiene. The exclusion criteria were as follows: acute dental and periodontal disease, all RPD abutment teeth connected to other teeth with fixed prostheses, and current use of RPD or ND during sleep. All candidates were informed of the study purpose in written descriptions of the protocol before they provided consent to participate.
Before recruitment, candidates were screened for SB using a miniature electromyogram device (BiteStrip). BiteStrip counts the amount of masseter muscle activity above the 30% of the maximum voluntary contraction level and produces a four-grade score based on the number of counted events (L: less than 30 events; 1: 31-60 events; 2: 61-100 events; 3: more than 101 events). In this study, candidates with a BiteStrip score of 2 or 3 were diagnosed with SB and recruited as participants. After recruitment, all abutment teeth on which the direct retainers were designed were assessed using clinical periodontal examinations. In addition, participants were also assessed for SB using BiteStrip at the 6-month follow-up assessment.
Afterward, the participants were randomly allocated into two groups: the intervention group (wearing night denture (ND) during sleeping) and the control group (wearing nothing during sleeping).
None.
Mobility of removable partial denture abutment tooth measured using electronic tooth mobility measuring device (Periotest).
