Background and Purpose To evaluate the clinical outcome of “simpli5y” concept where in 3 and 2 implant placed cross arch in maxilla and in mandible respectively, restored with screw retained prosthesis. Materials and Methods Total of 30 patients were randomized, with 15 in group1 with an average of 45 Ncm insertion torque with delayed loading and 15 in group 2 with above 65 Ncm inertion torque with immediate loading with equal number of male and female in each group following parallel design with 3 implants in maxillary and 2 implants in mandibular arch placed which was supported by a 3Dimensional finite analysis comparing the stress dissipation around implants of this concept—“Simplif5y” with All‐on‐4 concept. Results Von Mises strain recorded in the bone in the maxillary and mandibular arch models were higher in All‐on‐four than that in the “simpli5y”, which was vice‐versa in the framework. Three‐year post loading marginal peri implant bone loss for the group 1 was less than group 2. Conclusions These results, suggest that in both delayed loading and immediate loading protocol that cross arch prostheses can be successfully supported by 3 and 2 implants in maxillary and mandibular arch respectively—“Simpli5y” concept of full mouth restoration.
