The aim of this retrospective analysis was to report on the clinical outcome of immediate provisionalization using one-piece narrow-diameter implants.
The dental records of patients who received narrow implants were reviewed. Narrow-diameter (3.0-mm) one-piece implants were used to support restorations of missing maxillary lateral incisors and mandibular incisors. All implants were placed in a one-stage procedure according to the protocol recommended by the manufacturer, with immediate placement of provisional restorations. Following an average healing period of 3 months in the mandible and 5 months in the maxilla, the definitive prostheses were fabricated. The survival rate of the implants was analyzed, and radiographic evaluation was performed. RESULTS. Thirty-six patients (20 men and 16 women), aged from 42 to 72 years (average age of 53 years), were treated with 62 one-piece narrow implants. A success rate of 100% was observed over a period up to 33 months (mean, 23 ± 4.3 months). Among these, 8 implants were placed in maxillary lateral incisor positions and 54 implants were placed in mandibular incisor areas. Forty-four implants supported fixed partial prostheses, and 18 implants supported single crowns. The majority of the implants were 15 mm in length. Mean marginal bone loss at the 12-month follow-up visit was 0.53 ± 0.37 mm (range, 0 to 1.4 mm).
The results obtained in this retrospective analysis suggest that the one-piece narrow-diameter implant can predictably restore missing maxillary lateral incisors and mandibular incisor with narrow interdental spaces and labiolingual widths.
本回顾性分析旨在报告使用一体式窄径种植体即刻临时修复的临床效果。
回顾了接受窄径种植体治疗的患者的牙科记录。使用窄径（3.0 毫米）一体式种植体来修复上颌侧切牙和下颌切牙缺失。所有种植体均按照制造商推荐的方案在一期手术中植入，并立即放置临时修复体。在下颌平均愈合期 3 个月和上颌平均愈合期 5 个月后，制作最终修复体。分析了种植体的存活率，并进行了影像学评估。
36 名患者（20 名男性和 16 名女性），年龄 42 至 72 岁（平均年龄 53 岁），接受了 62 颗一体式窄径种植体治疗。在长达 33 个月的随访期内（平均 23 ± 4.3 个月），观察到 100%的成功率。其中，8 颗种植体植入上颌侧切牙位置，54 颗种植体植入下颌切牙区域。44 颗种植体支持固定局部义齿，18 颗种植体支持单冠。大多数种植体长度为 15 毫米。12 个月随访时平均边缘骨丧失为 0.53 ± 0.37 毫米（范围 0 至 1.4 毫米）。
本回顾性分析结果表明，一体式窄径种植体可稳定地修复缺牙间隙和唇舌宽度较窄的上颌侧切牙和下颌切牙。
