N2  - Background: To volumetrically assess the bone microstructure following vertical alveolar ridge augmentation using differently conditioned autogenous tooth roots (TR) and second‐stage implant placement.
Materials and methods: The upper premolars were bilaterally extracted in n = 4 beagle dogs and randomly assigned to either autoclavation (TR‐A) or no additional treatment (TR‐C). Subsequently, TR were used as block grafts for vertical alveolar ridge augmentation in both lower quadrants. At 12 weeks, titanium implants were inserted and left to heal 3 weeks. Microcomputed tomography was used to quantify bone volume per tissue volume (BV/TV), trabecular thickness (Tb.Th), and trabecular spacing (Tb.Sp) at vestibular (v) and oral (o) aspects along the implant and in the augmented upper half of the implant, respectively.
Results: Median BV/TV [TR‐C: 51.33% (v) and 70.42% (o) vs TR‐A: 44.05% (v) and 64.46% (o)], Tb.th [TR‐C: 0.22 mm (v) and 0.27 mm (o) vs TR‐A: 0.23 mm (v) and 0.29 mm (o)] and Tb.Sp [TR‐C: 0.26 mm (v) and 0.13 mm (o) vs TR‐A: 0.29 μm (v) and 0.15 mm (o)] values were comparable in both groups.
Conclusion: Both TR‐C and TR‐A grafts were associated with a comparable bone microstructure within the grafted area.
