Description
Eduardo Borie and four colleagues published a dental simulation study in two thousand twenty-five on how many implants a full upper denture needs. Implant-held overdentures can rest on two, three, or four posts. Computer stress modelling can show which counts keep bone loads safe.
A three-dimensional model of a shrunken toothless upper jaw was built from CT scans. Six versions varied implant count and outer bone thickness. Two-implant versions strained the spongy bone past the safety limit. Three- and four-implant versions kept stresses comfortably low. The three-implant tripod spread loads about as well as four. The authors call three implants a sound, cheaper option, with four plus thicker bone best overall.
