Outline of Final Research Achievements |
This randomized controlled trial aimed to study the effects of lining mandibular complete dentures with silicone-based resilient denture liners, especially with respect to sensation. The trial included completely edentulous patients who were willing to fabricate new set of complete denture. A random permuted block method was used to assign participants to one of the following groups: mandibular conventional denture (CD) group or mandibular denture with resilient denture liner (RD) group. The outcome was pain threshold for external stimuli measured using the Neurometer. The pain thresholds were significantly higher in the RD group than the CD group. This study concludes that edentulous patients wearing mandibular complete dentures with silicone-based resilient denture liners dull perception mandibular ridge mucosa and felt less pain than those without the liners.

Academic Significance and Societal Importance of the Research Achievements |
現在、軟質リライン材は保険収載され、顎堤条件が悪い無歯顎患者が適応症となり、難症例の患者の福音となっている。これまでに、軟質リライン材を使用することで、満足度が改善される、咀嚼能が向上する。使用時の痛みが少なくなる、歯ぐきに傷ができにくくなる、等の報告が行われていた。今回これに加え、痛みを感じ難くなると言う生理的な効果を提示する事ができた。そしてこの結果は無作為割付臨床試験にて導かれているのでエビデンスの度合いが高い。
