Comparison of Stresses Transmitted to One-Piece and Two-Piece Narrow-Diameter Implants in Mandibular Over Dentures (A Finite Element Stress Analysis)

Sarah Mohamed Moustafa | Mohamed Sherein Elattar | Tamer M. Ahmed


Abstract: The purpose of this study is to determine, using 3-dimensional finite element analysis, whether 1-piece and 2-piece narrow diameter implants with equivalent geometries exhibit stresses and strains differently under applied loading conditions when used to retain a mandibular overdenture and, to evaluate how stresses are transmitted to the surrounding bone. Materials and methods A computer based numerical model is structured for the anterior segment of the mandible with, 2 narrow diameter implants retaining a mandibular overdenture, one being a 1-piece and the other being a 2-piece. A 35N, and a 100N loads were applied through the overdenture, and Von Mises stresses were analyzed along the implants and the surrounding bone. Results Stresses around the 2-piece design were greater than those around the 1-piece design, but the values recorded were still below the yield strength of implants and bone. Conclusion A 2-piece narrow diameter implant can be a reliable treatment option to retain overdentures in cases where immediate loading is not recommended.
