title: Verification of the influence of the arrangement of implants on the load distribution (a well-known figure by Rangert).
abstract: The purpose of this study is to evaluate the effects of the number and the placement of implants on load distribution for multiple implants with three-dimensional geometric analysis, and to verify the well-known conceptual figure by Rangert. Three teeth missing in left mandibular region was geometrically modelled in clinically simulated situation. Two implants placement as 'control', 'cantilever', 'three-implants' and 'offset placements' were analyzed with geometric analysis. The cantilever received 180-182% load of control, that is, almost same to the result by Rangert (200%). Three implants received 59-65% load of control, that is, almost same to the result by Rangert (67%). Offset arrangement received 59-65% load of control, that is, larger than the result by Rangert (40%). It was concluded that the influence of the arrangement of implants on the load distribution presented in the conceptual figure by (Rangert BR, Sullivan RM & Jemt TM, J Oral Maxillofac Implants. 1997;12:360) was verified except for the effects of the offset arrangement.
