To compare the complications and implant survival rates of localized alveolar ridge deficiencies in the horizontal dimension reconstructed by alveolar ridge splitting (ARS) or autogenous onlay bone grafting (OBG).
Twenty-eight ARS and 28 OBG were performed. The survival rate of the all included implants was evaluated using the clinical and radiographical evaluation criteria of Misch et al. Temporary exposure of graft, mild infection, temporary paresthesia, and bad split were defined as minor complications; permanent exposure of graft, loss of graft, and permanent paresthesia were defined as major complications. Major and minor complications of ARS and OBG groups were statistically compared.
When the minor and major complication rates are considered, there was not any statistically significant difference between OBG (P = 0.099) and ARS (P = 0.241) groups. The satisfactory survival rate of OBG group was 92% and was 100% in the ARS group, and the difference was not statistically significant (P = 0.116).
When reconstructing vertically sufficient but horizontally insufficient alveolar ridges, ridge splitting technique could shorten the treatment period, decrease postoperative swelling and pain, eliminate the need for a second surgical site, reduce the treatment cost, and ease the patient cooperation to the surgery.
比较采用牙槽嵴劈开术（ARS）或自体块状骨移植术（OBG）重建水平维度局部牙槽嵴缺损的并发症及种植体存活率。
实施了28例ARS和28例OBG。采用Misch等人的临床和影像学评估标准评估所有纳入种植体的存活率。移植物临时暴露、轻度感染、临时感觉异常和不良劈开被定义为轻微并发症；移植物永久暴露、移植物丢失和永久感觉异常被定义为严重并发症。对ARS组和OBG组的严重及轻微并发症进行统计学比较。
考虑轻微和严重并发症发生率时，OBG组（P = 0.099）和ARS组（P = 0.241）之间无统计学显著差异。OBG组的满意存活率为92%，ARS组为100%，差异无统计学意义（P = 0.116）。
在重建垂直高度足够但水平宽度不足的牙槽嵴时，牙槽嵴劈开技术可缩短治疗周期，减轻术后肿胀和疼痛，无需第二个手术部位，降低治疗成本，并便于患者配合手术。
