The present study aims to investigate clinical and patient-centered outcomes after the implant-supported rehabilitation of narrow ridges using a novel wedge-shaped implant. Forty-four patients were treated with the insertion of 59 tissue-level wedge implants (1.8 mm bucco-lingual width) in horizontally atrophic ridges (mean bone width 3.8 ± 0.4 mm). The main outcome measures were: implant stability quotient (ISQ), marginal bone loss (MBL) and patient morbidity. Fifty-eight implants were functioning satisfactorily after one year of loading (98.3% survival rate). ISQ values measured in the mesio-distal direction resulted significantly higher than those in the bucco-lingual direction at all time points ( < 0.001). Both mesio-distal and bucco-lingual ISQ values at 6-month follow-up resulted significantly higher than at 4-month follow-up ( < 0.001 for both). Mean MBL was 0.38 ± 0.48 mm at prosthesis delivery (6 months after implant insertion) and 0.60 ± 0.52 mm after one year of functional loading. The majority of patients reported slight discomfort related to the surgical procedure. Postoperative pain score was classified as mild pain on the day of surgery and the first postoperative day and no pain over the following five days. Within the limitations of the present study, the device investigated showed low morbidity and positive short-term clinical results in narrow ridges treatment.
本研究旨在调查使用新型楔形种植体对狭窄牙槽嵴进行种植体支持的修复后的临床和以患者为中心的结果。44例患者在水平萎缩的牙槽嵴（平均骨宽度3.8±0.4mm）中植入了59枚组织水平的楔形种植体（颊舌宽度1.8mm）。主要观察指标为：种植体稳定性商数（ISQ）、边缘骨丢失（MBL）和患者发病率。58枚种植体在加载一年后功能良好（存活率98.3%）。在所有时间点，沿近远中方向测量的ISQ值均显著高于沿颊舌方向测量的值（<0.001）。6个月随访时的近远中向和颊舌向ISQ值均显著高于4个月随访时的值（两者均<0.001）。假体交付时（种植体植入后6个月）的平均MBL为0.38±0.48mm，功能加载一年后的平均MBL为0.60±0.52mm。大多数患者报告与手术过程相关的轻微不适。术后疼痛评分在手术当天和术后第一天为轻度疼痛，在接下来的五天内无疼痛。在本研究的局限性范围内，所研究的器械在狭窄牙槽嵴治疗中显示出低发病率和积极的短期临床结果。
