The aim of this study was to analyze the stress state caused by biting forces upon insertion of partial dentures into the assembly, and to understand the influence of the resulting contact pressure on its retention behavior. For this purpose, a numerical model of a removable partial denture is proposed based on 3D models developed using computer tomography data of the jawbone and the removable partial denture. The denture system rests on the oral mucosa surface and three abutment teeth. The application of bite forces on the denture generated a stick condition on the loaded regions of the denture\u2010oral mucosa interface, which indicates positive retention of the denture onto the oral mucosa surface. Slip and negative retention were observed in the regions of the contact space that were not directly loaded. The contact pressures observed in the regions of the oral mucosa in contact with the denture were below the clinical pressure pain threshold value for soft tissue, which potentially lowers the risk of pain being experienced by denture users. Further, the variation of the retention behavior and contact pressures across different regions of the denture assembly was observed. Thus, there is a need for adhesives or restraining mechanisms for the denture system in order to avoid bending and deformation of sections of the denture as a consequence of the applied bite force.<\/jats:p>","DOI":"10.1002\/cnm.3604","type":"journal-article","created":{"date-parts":[[2022,4,14]],"date-time":"2022-04-14T01:58:47Z","timestamp":1649901527000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Numerical study of the stress state on the oral mucosa and abutment tooth upon insertion of partial dentures in the mandible"],"prefix":"10.1002","volume":"38","author":[{"given":"Anantha Narayanan","family":"Ramakrishnan","sequence":"first","affiliation":[{"name":"Department of Biological and Macromolecular Materials Fraunhofer Institute for Microstructure of Materials and Systems IMWS  Halle Germany"},{"name":"Institute for Modelling and Simulation of Biomechanical Systems University of Stuttgart  Stuttgart Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oliver","family":"R\u00f6hrle","sequence":"additional","affiliation":[{"name":"Institute for Modelling and Simulation of Biomechanical Systems University of Stuttgart  Stuttgart Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Ludtka","sequence":"additional","affiliation":[{"name":"J.
