Summary 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.
