In conclusion and within its limitations, the present clinical study revealed that TR grafts may be associated with improved SA26 values following lateral alveolar ridge augmentation.
When further analyzing the present data, it was also noted that both TR and AB grafts were associated with comparable BI26 values, thus corroborating the clinical observation of a firm graft connection to the host bone at 26Â weeks, which allowed for a proper placement of adequately dimensioned titanium implants at all sites investigated [9]. The regression analysis also revealed that BI26 values ...
The present analysis aimed at assessing and comparing CBCT outcomes following lateral alveolar ridge augmentation using TR and AB grafts. After a healing period of 26Â weeks, it was observed that TR grafts were associated with significantly higher mean SA26 values when compared with the AB group. A similar tendency was also noted for mean BI26 values; however, this difference did not reach statist...
Mean CWb and GT values were comparable in both groups and amounted to 4.53 ± 1.54 mm (median 4.50; 95% CI 3.68, 5.38) and 5.66 ± 1.75 mm (median 5.0; 95% CI 4.69, 6.64) in the TR group and 5.26 ± 1.25 mm (median 5.00; 95% CI 4.57, 5.95) and 4.96 ± 1.75 mm (median 5.0; 95% CI 4.24, 5.68) in the AB group, respectively. Between-group differences did not reach statistical signi...
All measurements were performed by one previously calibrated investigator.
The sample size calculation considered a standard normal distribution (type I error set at .05; type II error set at .20) and a sigma which was estimated based on the standard deviations observed in a recent preclinical animal study [4]. The clinical width of the alveolar ridge was defined as the primary outcome variable, ...

This analysis was based on the radiographic (i.e., cone-beam computed tomographic—CBCT) data derived from a prospective controlled clinical monocenter study including a total of 30 patients [9]. Each participant exhibited either a tooth gap or a free-end situation with an inadequate horizontal ridge width and was in need of an implant-supported fixed restoration.
In brief, lateral ridge augment...
Autogenous bone (AB) blocks harvested from intraoral donor sites (i.e., retromandibular, chin) are the most commonly used procedure for lateral alveolar ridge augmentation [1]. However, despite significant horizontal bone gains, cortical bone blocks were noted to undergo an incomplete replacement resorption [2, 3], thus featuring a composition of non-vital residual and newly formed vital bone in t...
To assess and compare the radiographic outcomes following lateral alveolar ridge augmentation using autogenous tooth roots (TR) and autogenous bone (AB) blocks.
In a total of 30 patients, lateral ridge augmentation was conducted in parallel groups using either (1) healthy autogenous tooth roots (e.g., retained wisdom or impacted teeth) (n = 15) or (2) cortical autogenous bone blocks harvested...
