Abstract

Aim:- To evaluate and compare the effect of thread geometry i.e. V-shape, Square and Buttress under 100 N force on peri-implant bone via Finite Element. Materials & Method:- Three virtual models was prepared having implants with different thread designs:- V– thread design Model I; Square thread design Model II and Buttress thread design Model III. Loading points were marked on the superstructure (crowns virtually fabricated for each of the abutments) and 100N of vertical and oblique forces at an angle of 45º were applied. ANSYS software was used for qualitative and quantitative stress analysis. Maximum von Mises stresses and strain values at the implant surface and abutment were recorded. Results:- Highest displacement was seen in square shaped thread designed implants (0.46) followed by buttress shaped and then V-shaped thread design of implants (0.056). The mean stress for V-shaped design implants, square shaped design implants and buttress design implants were 6.12, 6.18 and 6.11 respectively. Highest difference in stress on abutment was 33.84, 32.59 and 20.53 in V shaped, square shaped and buttress shaped designs respectively. Conclusion:- Square shape thread design has biomechanical advantages in terms of reducing stress concentration and microstrain in bone.
