Abstract Objectives To assess biomechanical, micro‐computed tomographic (micro CT ) and immunohistochemical characteristics of early osseous integration at titanium implants placed following lateral ridge augmentation using autogenous extracted tooth roots. Material & Methods The roots of healthy maxillary premolars ( PM ) and retromolar cortical autogenous bone ( AB ) blocks were used for lateral ridge augmentation at chronic‐type defects in the lower quadrants of n = 16 foxhounds. At 12 weeks, titanium implants were inserted and left to heal for another 3 weeks. Osteocalcin ( OC ) antigen reactivity, removal torque values ( RT ) and the bone volume per tissue volume (micro CT ‐ BV / TV ) along the implants were assessed. Results Median OC ( PM : 6.71 vs. AB : 2.73%), RT ( PM : 61.97 vs. AB : 44.8 Ncm) and BV / TV ( PM : 0.34 vs. AB : 0.21) values were comparable in both PM and AB groups. Conclusions PM and AB grafted sites equally supported the early stages of osseointegration.
