Influence of using oral appliances during sleep on conditions of remaining teeth and residual ridges in removable partial denture wearers

Not Applicable

• Conditions: partially edentulous dental arch sleep bruxism

• Registration Number: JPRN-UMIN000033316
• Lead Sponsor: Tokyo Medical and Dental University (TMDU)

Brief Summary

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.
