Abstract

OBJECTIVE

To evaluate clinical results of implant supported telescopic overdenture.

METHODS

21 patients with edentulous jaws underwent telescopic overdenture restoration. A total of 28 prostheses were fabricated. Of them, 13 were in the upper jaws, 15 in the lower jaws. Among 139 placed implants, 74 were Camcog, 28 IMZ, and 37 Frialit-2. The secondary crown was fabricated by electroforming technique and wax-lost cast method. Clinical examination and radiographs were conducted. Changes in the marginal bone level around the implants were evaluated with radiograph. The mean follow-up time was 26.5 months (range 12 - 39 months).

RESULTS

This type of restoration could provide sufficient stability and maintain peri-implant hygiene easily. Peri-implantitis and prosthetic complications were not observed. Marginal bone around implants was stable. No implant was lost during the loading time.

CONCLUSIONS

The preliminary clinical results of this research showed that implant supported telescopic overdentures were predictable for edentulous patients.

摘要

目的

评估种植体支持的套筒冠覆盖义齿的临床效果。

方法

21例无牙颌患者接受套筒冠覆盖义齿修复。共制作了28副义齿，其中上颌13副，下颌15副。在植入的139枚种植体中，74枚为Camcog种植体，28枚为IMZ种植体，37枚为Frialit-2种植体。采用电铸技术和失蜡铸造法制作二级冠。进行临床检查和影像学检查。通过影像学评估种植体周围边缘骨水平的变化。平均随访时间为26.5个月（范围12 - 39个月）。
