| Research Abstract |
For mandibular edentulous patient, biomechanical study was performed on the implant overdeture assisted by one (midline) or two implants (left and right canine regions) on the simulation model.
As for the one implant support, tensile strain was observed on the buccal, right, and left sides, and compressive strain was occurred on the lingual side regardless of kinds of the attachments. The greater pressure distribution was shown on the soft tissue around the first molar region compared to the first premolar region. Similarly, in the two implant support, tensile strain was observed on the buccal and medial sides, and compressive strain was occurred on the lingual and medial sides regardless of kinds of the attachments. The pressure distribution on the soft tissue around the first molar region was higher than that of the first premolar region.
