Abstract

One model was constructed representing mandibular completely edentulous case. On this model, two implants were placed in the canine regions. Two identical experimental overdentures were constructed. The first overdenture was fitted to two ball attachments while the second one was fitted to a curved bar attachment following the arch curvature connecting the two implants. Four strain gauges were installed, on the labial and distal sides of each implant to record the strain induced by the loads applied. A special loading device was used to apply standardized static vertical load on lower central incisors and bilaterally on first molars for each experimental overdenture. It was found that curved bar induce more stresses than ball attachments. It was concluded that Stresses transmitted to the implants using curved bar were much higher than that transmitted by the use of ball attachments.
