Clinical efficiency of one-piece screw-type implants with telescopic were attachments evaluated in this study. Twenty-four patients received a mandibular implant-supported overdenture and maxillary complete denture. Ninety-six one-piece implants were inserted in the inter-foraminal area. Implants were immediately loaded with an implant-retained overdenture and telescopic attachments which had frictional retention elements. There was 0.25±0.24 mm, 0.32±0.25 mm, 0.43±0.30 mm, 0.61±0.30 mm and of bone resorption after 3, 6, 12 and 24 months, respectively. The need to activate the frictional retention was the most common complication. Treatment outcomes for prefabricated telescopic retained overdentures on one-piece implants are similar to that obtained in cases of delayed loading.
本研究评估了带套筒冠附着体的一体式螺旋种植体的临床疗效。24例患者接受了下颌种植支持覆盖义齿和上颌全口义齿修复。在双侧颏孔间区域植入96枚一体式种植体。种植体即刻负载种植体固位覆盖义齿及带有摩擦固位元件的套筒冠附着体。在3个月、6个月、12个月和24个月时,骨吸收分别为0.25±0.24mm、0.32±0.25mm、0.43±0.30mm和0.61±0.30mm。需要激活摩擦固位是最常见的并发症。预制套筒冠固位覆盖义齿在一体式种植体上的治疗效果与延期负载病例相似。
