背景有限的研究集中在应用水平骨增量维持牙槽嵴顶部的骨轮廓。目的介绍一种名为“原位骨环技术”的新型方法，与帐篷柱技术进行比较，以评估其水平骨增量、吸收和术后感知。材料和方法这项回顾性队列研究共纳入30例患者。所有患者均需要在前部进行水平骨增量。并对原位骨环组和帐篷-杆技术组的X线片和组织学进行定量和定性分析。结果锥形束CT检查结果显示，两组患者距牙槽嵴0 mm和3 mm处的水平骨宽度差异有统计学意义（P < .05）。根据组织学结局，成形环组术后6个月显示良好的骨融合。结论原位骨环技术较帐篷-杆技术明显增加并维持了牙槽嵴顶部水平骨量，有利于前牙区种植修复。两组VAS评分均无进一步不适。
Background Limited studies focused on the bone profile maintenance at the alveolar ridge crest applying horizontal bone augmentation.Purpose 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.Materials and methods 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.Results 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.Conclusions 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.
