The aim of the present study was to evaluate and compare the patient-reported experience and outcome measures (PREMS and PROMS) and three-dimensional augmentation efficacy of the autogenous and allogenic bone block grafts in deficient alveolar ridges through cone beam computed tomography (CBCT).
Twenty patients were equally divided into Groups I and II treated with autogenous and allogenic bone block grafts for ridge augmentation, respectively. The radiographic parameters including the apico-coronal defect height (DH) as well as buccolingual defect depth (DD) and mesiodistal defect width (DW) at apical, middle, and cervical zone were measured using CBCT at baseline, 6 months and 1 year. The PREMS and PROMS were evaluated using Visual analogue scale (VAS) scale and questionnaire method.
The mean DH, apical DD and DW, middle and cervical zone DW were significantly different between two study groups ( < 0.05). The mean apical 11.6 ± 1.91 and middle zone 9.43 ± 0.89 DD were significantly higher (in Group I as compared to Group II, with values 0.016 and 0.004, respectively). The mean bone gains in apico-coronal DH and mesio-distal DW dimension in the apical and middle zone was significantly higher in Group I ( < 0.0001). The comparison of PROM revealed better patient satisfaction in Group II as depicted by significantly higher VAS score ( < 0.0001).
Superior bone gain and reduced graft resorption was observed in Group I when compared to Group II. On the contrary, better PROMs and PREMs were obtained with the allogenic bone block augmentation.
本研究旨在通过锥形束计算机断层扫描（CBCT）评估和比较患者报告的自体骨块移植和同种异体骨块移植在牙槽嵴缺损中的经验和结果指标（PREMS和PROMS）以及三维增高效果。
20例患者平均分为I组和II组，分别接受自体骨块移植和同种异体骨块移植进行牙槽嵴增高术。在基线、6个月和1年时使用CBCT测量包括根尖-冠向缺损高度（DH）以及根尖、中部和颈部区域的颊舌向缺损深度（DD）和近远中向缺损宽度（DW）等影像学参数。使用视觉模拟量表（VAS）和问卷调查法评估PREMS和PROMS。
两个研究组之间的平均DH、根尖DD和DW、中部和颈部区域DW存在显著差异（<0.05）。I组的平均根尖11.6±1.91和中部区域9.43±0.89的DD显著更高（与II组相比，I组的值分别为0.016和0.004）。I组根尖和中部区域的根尖-冠向DH和近远中向DW维度的平均骨增量显著更高（<0.0001）。PROMS的比较显示II组患者满意度更高，VAS评分显著更高（<0.0001）。
与II组相比，I组观察到更好的骨增量和减少的移植物吸收。相反，同种异体骨块增高术获得了更好的PROMS和PREMS。
