Objectives The aim of this study was to perform a histomorphometric and biomechanical comparison of three implants with different designs of the apical area to promote a better bone initial stability and its correlation with the osseointegration. Material and methods Fifty‐four tapered implants with same length, diameter and surface properties but with three different apical configurations (Group I: MK 4: Group II : C1 and Group III : MK 7) were inserted in the tibia of rabbits. Implant stability and bone formation were evaluated by resonance frequency analysis measured at 0, 6, 8 and 12 weeks and by histomorphometric analysis performed at 6, 8 and 12 weeks. Results Statistical test to compare the stability through the implant stability quotient in the four times showed few differences between the groups and time periods proposed, with significance set at P < 0.05. In the bone–implant contact, by comparing the groups in the three times proposed, it was possible concluded that there is a similar behavior among the three implant design ( P < 0.05). Conclusion With the limitations of this animal study, it can be concluded that the design of the apical area influences the implant stability and the bone‐to‐implant contact.
