AIM: The aim of the present study was to analyze stress and strain distribution in dental implants with different abutment's inclination inserted in D1 and D4 bone. METHODS: The biomechanical behavior of 5 mm x 16 mm dental implants with straight, 15 degrees and 25 degrees angulated abutments subjected to static loads, in contact with D1 and D4 bone, was evaluated by Finite Element Analysis (FEA). RESULTS: The lowest stress and strain values were found in the system composed by implants with straight abutments loaded with a 200-N vertical strength, while the highest stress and strain values were found in implants with 15 degrees angulated abutment loaded with a tilted strength (FY=200 N and FZ=140 N). Stress value increased from D1 to D4 bone, while strain value decreased due to the effect of normal elasticity mode of biological tissues. CONCLUSION: The different stress and strain distribution in D1 and D4 bone tissue surrounding dental implants with a tapered neck could favor prosthetic load and play a role in implant long-term success.
