New Design for an Adjustable Cise Space Maintainer

OBJECTIVE: The aim of this study is to present a new adjustable Cise space maintainer for preventive orthodontic applications. METHODS: Stainless steel based new design consists of six main components. In order to understand the major displacement and stress fields, structural analysis for the design is considered by using finite element method. RESULTS: Similar to major displacement at y-axis, critical stresses σ(x) and τ(xy) possess a linear distribution with constant increasing. Additionally, strain energy density (SED) plays an important role to determine critical biting load capacity. CONCLUSION: Structural analysis shows that the space maintainer is stable and is used for maintaining and/or regaining the space which arouses early loss of molar tooth.
