  1. Inference: (laterals recorded the highest stresses in all models)
  2. Group I: In consolidation, 10-mm implant height and non-consolidation 13-mm implant height showed highest von Mises stresses. Principle tensile stresses are high in 10-mm consolidation implant model and 13-mm non consolidation implant model
  3. Group II: In consolidation and non-consolidation, von Mises stresses are high in 13-mm implant height, and principle stresses are more in 10-mm in consolidation and 13-mm in non-consolidation implant heights
