Objectives The aim of this animal study was to examine the effects of thread size in the implant neck area on peri‐implant tissues in terms of BIC and hard‐ and soft‐tissue dimensions. Materials and methods Six Beagle dogs received experimental implants in the mandible 3 month after the removal of premolars and first molars (P2, P3, P4, and M1). Two different types of implants were installed in each animal: Anyone microthread ® as Group 1 and Anyone ® as Group 2. Resonance frequency test, intraoral radiography, micro‐ CT , and histomorphometry were used to evaluate peri‐implant tissue after implantation periods of 4 and 8 weeks. Results No remarkable complication was observed during the healing period in either group. Resonance frequency testing revealed no significant difference between groups. In radiographic evaluation, Group 2 showed more bone loss than Group 1. However, this difference was not statistically significant. In the micro‐ CT analysis, BIC and BIV values and soft‐tissue height were not significant in both groups. Histological analysis revealed no significant difference in BIC ratio, bone density, or bone loss between groups. However, soft‐tissue height was significantly greater in Group 2 than in Group 1 ( P = 0.0004). Conclusion No difference in peri‐implant hard or soft tissues was observed according to thread size in the implant neck area.
