To address the problem of insufficient bone mass in the implant area, we focused on the vertical increment of the posterior mandibular area to increase bone mass with the aid of a healing abutment. Data of patients with insufficient vertical bone height in the posterior mandibular area were collected, and vertical increment of alveolar bone operations was performed with the aid of a healing abutment. Preoperative residual alveolar bone height, immediate postoperative alveolar bone height, and 6-month postoperative alveolar bone height were recorded, with peri-implant soft tissue results 6 months after surgery using the modified plaque index and sulcus bleeding index. Twelve patients, aged 42–73 years, with an average age of 55.91 ± 11.58 years, received vertical bone augmentation in the posterior mandibular region supported by implant healing abutments. Fifteen SLA TSIII OSSTEM implants were utilized in the 12 patients; one patient failed in vertical bone augmentation at one site (H0 = 0 mm). The vertical bone augmentation effect of two patients at two sites was 0 mm < H0 < 1 mm, and the vertical bone augmentation effect of 12 sites in nine patients was H0 ≥ 1 mm. The implant success rate was 93.3%, and the mean vertical bone gain was 2.91 mm. Peri-implant soft tissue parameters are as follows: mean modified plaque index, 1.92; mean modified sulcus bleeding index, 1.21; and mean probing depth, 3.18. No clinically observable complications occurred. Bone augmentation supported by the implant healing abutment showed the characteristics of “platform transfer”, with good formation of the implant–bone interface. The bone augmentation surgery was completed at the same time as the implant placement, which reduced the pain of multiple operations and shortened waiting times. We provide a novel idea to solve the problem of insufficient vertical bone height in the posterior mandibular region.

支持垂直骨增量的种植体愈合基台在下颌后牙区的应用
针对种植区骨量不足的问题，我们着重于下颌后牙区的垂直增量，借助愈合基台增加骨量。收集下颌后牙区垂直骨高度不足患者的资料，借助愈合基台进行牙槽骨垂直增量手术。记录术前残余牙槽骨高度、术后即刻牙槽骨高度和术后 6 个月牙槽骨高度，并使用改良菌斑指数和牙龈沟出血指数记录术后 6 个月的种植体周围软组织结果。12 名患者，年龄 42-73 岁，平均年龄 55.91 ± 11.58 岁，在种植体愈合基台的支持下，在下颌后牙区接受了垂直骨增量术。12 名患者使用了 15 个 SLA TSIII OSSTEM 种植体；一名患者在一个部位（H0 = 0 mm）的垂直骨增量失败。2例2个部位的垂直骨增量效果为0 mm < H0 < 1 mm，9例12个部位的垂直骨增量效果为H0 ≥ 1 mm。植入成功率为 93.3%，平均垂直骨增量为 2.91 mm。种植体周围软组织参数如下：平均改良菌斑指数，1.92；平均改良沟出血指数，1.21；和平均探测深度，3.18。没有发生临床可观察到的并发症。种植体愈合基台支持的骨增量表现出“平台转移”的特点，种植体-骨界面形成良好。骨增量手术与种植体植入同时完成，减少了多次手术的痛苦，缩短了等待时间。我们提供了一种解决下颌后牙区垂直骨高度不足问题的新思路。
