It is very difficult to achieve denture support, stability and retention in single-maxillary complete denture patients with flabby tissue. A 57-year-old male patient was uncomfortable with the existing denture and wanted treatment. The reduction of flabby tissue was confirmed using the treatment denture. Non-pressure impression was obtained using an intraoral scanner during the definitive denture process. This is reported because the resulting denture improved when observing the retention, support and stability of the denture during occlusion.

This study summarizes the recent cutting-edge approaches for dentin regeneration that still do not offer adequate solutions. Tertiary dentin is formed when odontoblasts are directly affected by various stimuli. Recent preclinical studies have reported that stimulation of the Wnt/β-catenin signaling pathway could facilitate the formation of reparative dentin and thereby aid in the structural and functional development of the tertiary dentin. A range of signaling pathways, including the Wnt/β-catenin pathway, is activated when dental tissues are damaged and the pulp is exposed. The application of small molecules for dentin regeneration has been suggested as a drug repositioning approach. This study reviews the role of Wnt signaling in tooth formation, particularly dentin formation and dentin regeneration. In addition, the application of the drug repositioning strategy to facilitate the development of new drugs for dentin regeneration has been discussed in this study.
