The effect of implant number and position on the stress behavior of mandibular implant retained overdentures: A three-dimensional finite element analysis

Stress Distribution of Dental Implants in Lateral or Canine Areas: A Three-Dimensional Finite Element Analysis

“…Implant-retained overdentures are the primary treatment method applied to edentulous patients today 3 . However, the distribution of stress in dental implants remains a highly controversial issue in the literature 1,6,7,15,16 . Kan et al 6 described that the inter-implant distance is important in the distribution of stress.…”

“…The FEA is the adequate method for evaluating stress analyzes of implants. Few FEA studies comparing the locations of endosseous anterior implants in the edentulous mandible are available 1,6,7,17 and most of the published research evaluates the number of implants to be applied using FEA 1,18 . Topkaya and Solmaz 1 reported that the stresses measured in four-implant-supported models are lower than those measured in two-implant-supported models.…”

“…In previous studies, the force was applied to the implant, abutment, and prosthetic materials at an angle 1,6,7,16,17 . Meijer et al 7 applied vertical, 35 N; horizontal, 10 N; and oblique, 70 N static forces on an angular bar.…”

“…Preservation of esthetics and restoration of lost tissues has long been the main purpose of dentistry 1 . The invention of osseointegrated dental implants has increased the usability of prosthetic applications in edentulous patients 2 .…”

Clinical Performance of Implant Overdenture Versus Fixed Detachable Prosthesis

“…11 Concerning stresses around the implant site, a four implants model demonstrated less stress than two implants in all directions of loading. 12 While clinical and radiographical data revealed no difference between two and four implants. 9…”
