Methods: The 3-dimensional models of experimental round and triangular threads dental implants were made by the measurement data obtained from an actual dental implant with the help of Patran (2010, MSC software)．The experimental dental implants had round and triangular thread design of the implant threads. The bone and implant were represented as elastic-plastic and rigid respectively. The angular speed of the implants was 1.05 rad/sec. The dental implants were inserted into a tapered cavity. The data was analyzed using Marc Mentat (2008 r1, MSC software). The total time for the insertion of the dental implants was 1.3 sec. The movements of both dental implants was analyzed and compared in relation to Von-Misses stress pattern.
Results: The stress pattern, maximum stress, total stress at peri-implant bone and adaptive meshing inside bone were found to be lower in round threads dental implants as compared to triangular threads dental implants.
Conclusions: Within the limitation of this study we can conclude, that the round threads dental implants have less amount, magnitude and simple stress pattern as compared to triangular threads dental implant at peri-implant bone.
