Limited studies focused on the bone profile maintenance at the alveolar ridge crest applying horizontal bone augmentation.
A novel approach named as "in-situ bone ring technique" was introduced to be compared with tent-pole technique to evaluate their horizontal bone gain, resorption, and postoperative perception.
A total of 30 patients were included in this retrospective cohort study. All patients required horizontal bone augmentation at anterior site. Accordingly, quantitative and qualitative analyses were conduct radiographically and histologically between in-situ bone ring (ring group) and tent-pole technique (tent group). Moreover, the visual analog scale (VAS) was introduced to assess the patients' perception toward both treatments.
Cone-beam computed tomography results showed great significant difference regarding horizontal bone width at 0 mm and 3 mm from alveolar ridge crest between two groups (P < .05). On the basis of histological outcomes, delightful bony fusion was shown 6-month postoperatively in ring group. The VAS ratings for pain and swelling reflected similar results between two groups.
In-situ bone ring technique evidently increased and maintained horizontal bone mass at the alveolar ridge crest compared to tent-pole technique, which might be favorable for implant rehabilitation in anterior area. Meanwhile, no further discomfort was caused according to VAS scoring between two groups.
有限的研究集中在应用水平骨增量时牙槽嵴顶的骨轮廓维持。
引入了一种名为“原位骨环技术”的新方法，与帐篷杆技术进行比较，以评估它们的水平骨增量、吸收和术后感知。
这项回顾性队列研究共纳入 30 名患者。所有患者均在前部需要水平骨增强。因此，在原位骨环组（环组）和帐篷杆技术组（帐篷组）之间进行了影像学和组织学的定量和定性分析。此外，还引入了视觉模拟评分（VAS）来评估患者对两种治疗方法的感知。
锥形束 CT 结果显示，两组在牙槽嵴顶 0mm 和 3mm 处的水平骨宽度有显著差异（P<0.05）。根据组织学结果，环组术后 6 个月显示出令人愉悦的骨融合。疼痛和肿胀的 VAS 评分在两组之间反映出相似的结果。
与帐篷杆技术相比，原位骨环技术明显增加和维持了牙槽嵴顶的水平骨量，这可能有利于前牙区的种植体修复。同时，根据 VAS 评分，两组之间没有引起进一步的不适。
