Background: It is generally believed that implants placed in extraction sockets have a tendency to shift in the facial direction during insertion. The purpose of this study is to investigate the effect of different thread designs on the final implant position in immediate implant placement. Methods: In a split‐mouth design involving 11 cadaver heads, each specimen received two implants, one with a square and one with a V‐shaped thread design, in maxillary incisor extraction sockets. The facio‐lingual locations of the drills and the implant were tracked, and the displacements were compared between the two groups. Results: No statistically significant differences were observed between the square and V‐shaped thread design groups. The mean displacements of the different groups showed a general tendency of the implants to be positioned facially compared with the initial drill trajectory. This tendency was greater for implants with square thread design. Conclusion: There was no significant effect of implant thread design on the positioning of implants in extraction sockets.
