To assess the clinical, radiographic, aesthetic, and patient-centred outcomes of a new implant system applied for an immediate implant placement and restoration approach in single tooth replacement of anterior maxillary teeth. . Three cases were treated with a bone level tapered implant. All patients were treated with the same strategy involving flapless extraction and implant placement with simultaneous augmentation. Implants were provisionally restored with a screw-retained restoration at the day of surgery. Definitive restoration was fabricated after 3 months. Follow-up was one year after definitive restoration.
At the 1-year follow-up, the implants were stable and no complications had occurred. Peri-implant bone levels had increased with a mean value of 0.24 ± 0.30 mm between definitive restoration placement and 1 year of follow-up. Clinical outcome scores showed healthy soft tissues. Mean Pink and White Esthetic scores were rated 7.0 and 7.3, respectively. Mean patient satisfaction had improved from 55.7 (pretreatment) to 90.0 (1-year follow-up) on a 0-100 VAS scale.
Immediate implant placement and restoration with the new tapered bone level implant system are accompanied by good initial clinical and radiographic results as well as high patient satisfaction.
评估一种新型种植系统用于上颌前牙单颗牙即刻种植和修复的临床、影像学、美学及以患者为中心的效果。3例患者采用骨水平锥形种植体治疗。所有患者均采用相同策略,即不翻瓣拔牙并同期进行种植体植入及增量手术。手术当天用螺丝固位修复体对种植体进行临时修复。3个月后制作最终修复体。最终修复后随访1年。
在1年随访时,种植体稳定,未发生并发症。在最终修复体就位至1年随访期间,种植体周围骨水平平均增加了0.24±0.30毫米。临床结果评分显示软组织健康。粉色美学评分和白色美学评分的平均值分别为7.0和7.3。在0至100的视觉模拟量表上,患者满意度平均值从治疗前的55.7提高到了1年随访时的90.0。
使用新型锥形骨水平种植系统进行即刻种植和修复,具有良好的初始临床和影像学效果以及较高的患者满意度。
