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 from the retromolar area. Cone-beam computed tomographic (CBCT) scans taken at 26 weeks of submerged healing were analyzed for the basal graft integration (i.e., contact between the graft and the host bone in %) (BI26) and the cross-sectional grafted area (mm) (SA26).
Both groups revealed a comparable clinical width of the alveolar ridge at baseline (CWb). Mean BI26 and SA26 values amounted to 69.26 ± 26.01% (median 72.44) and 22.07 ± 12.98 mm (median 18.83) in the TR group and 79.67 ± 15.66% (median 78.85) and 12.42 ± 10.11 mm (median 11.36) in the AB group, respectively. Between-group differences in mean SA26 values were statistically significant (p = 0.031). Linear regression analysis failed to reveal any significant correlations between BI26 and CWb/SA26 values in either group.
TR grafts may be associated with improved SA26 values following lateral alveolar ridge augmentation.

评估并比较使用自体牙根（TR）和自体骨（AB）块进行外侧牙槽嵴增高术后的影像学结果。
总共30例患者，平行分组进行外侧牙槽嵴增高术，一组使用（1）健康的自体牙根（如保留的智齿或阻生牙）（n = 15），另一组使用（2）从磨牙后区获取的皮质自体骨块。对愈合26周时的锥形束计算机断层扫描（CBCT）图像进行分析，测量基底部植骨整合情况（即植骨与宿主骨之间的接触百分比）（BI26）和横断面植骨面积（mm）（SA26）。
两组在基线时牙槽嵴的临床宽度（CWb）相当。TR组的平均BI26和SA26值分别为69.26±26.01%（中位数72.44）和22.07±12.98 mm（中位数18.83），AB组分别为79.67±15.66%（中位数78.85）和12.42±10.11 mm（中位数11.36）。两组间平均SA26值的差异具有统计学意义（p = 0.031）。线性回归分析未发现两组中BI26与CWb/SA26值之间存在任何显著相关性。
外侧牙槽嵴增高术后，TR植骨可能与更好的SA26值相关。
