objective: The purpose of this study is to compare the stresses induced within the bone surrounding the Trabecular Metal Dental Implant (Zimmer Dental Inc., Carlsbad, CA, USA) in comparison to the stresses induced within the bone surrounding its predicate Tapered Screw Vent Implant (Zimmer Dental Inc., Carlsbad, CA, USA) using three dimensional finite element analysis. materials and methds: The current finite element analysis simulated a clinical situation where an edentulous mandible was restored with an entirely implant supported cantilever bar overdenture retained by five implants placed parallel to each other in the interforaminal region opposed by a complete denture. Two models were constructed with difference only in the structures of the implants used. In model I Tapered Screw Vent Implants with MTX Surface were used. In model II Trabecular Metal Dental Implants the premium addition to Tapered Screw Vent Implants were used. 150 N vertical load was applied at the area of second premolar and first molar. results: Trabecular Metal Dental Implants induced less stresses within the surrounding bone than Tapered Screw Vent Implants. conclusion: Trabecular Metal Dental Implant introduces a new dimension to implant dentistry.
