Abstract

To assess the influence of autoclavation on the efficacy of extracted tooth roots (TR) used for vertical alveolar ridge augmentation and two-stage osseointegration. Maxillary premolars were randomly assigned to either autoclavation (TR-A) or were left untreated (TR-C) and used as block grafts for vertical alveolar ridge augmentation in both lower quadrants (n = 4 beagle dogs). At 12 weeks, titanium implants were inserted and left to heal for 3 weeks. Histological analyses considered vertical bone gain (BD-BC), augmented area (AA) and bone-to-implant contact (BIC) at vestibular (v) and oral (o) aspects. Both TR-C and TR-A (exposures n = 3) grafts were associated with a replacement resorption and marked vertical bone gain. Median BD-BC (TR-C: 1.45 [v] to 1.62 mm [o] versus TR-A: 0.97 [v] to 1.79 mm [o]) and AA (TR-C: 0.64 [v] to 2.36 mm2 [o] versus TR-A: 0.22 [v] to 2.36 mm2 [o]) values were comparable in both groups. V BIC (TR-C: 49.32 [v] to 52.97% [o] versus TR-A: 25.34 [v] to 46.11% [o]) values were significantly higher in the TR-C group. Both TR-C and TR-A grafts equally supported vertical alveolar ridge augmentation; however, osseointegration was partially facilitated in the TR-C group.
