Abstract

OBJECTIVE

The aim of this prospective clinical study was to evaluate the survival rates at 5 years of expanded platform implants placed in the anterior zone of the maxilla and immediately restored with single crowns.

MATERIALS AND METHODS

Implants incorporating the platform-switching concept were placed in fresh extraction sockets in the maxillary arch, with each patient receiving a provisional restoration immediately after implant placement. After 15 days, final screwed restorations were inserted. Mesial and distal bone heights were evaluated using digital radiography on the day following implant placement and at 1, 3, 6, 9, 12, 24, 36 months and 5 years. Primary stability was measured with resonance frequency analysis (RFA) using the Osstell Mentor device. Sixty-four implants were placed in 32 men and 32 women ranging in age between 29 and 60 (mean: 39.64 ± 5.16 years).

RESULTS

Mean mesial bone loss was 0.08 mm (SD 0.42). Mean distal bone loss was 0.14 mm (SD 0.56). Over the course of the 5 years, the mean RFA value was 72.5 ± 3.1 SD.

CONCLUSION

The platform-switched implants remained stable over the course of 5 years and had an overall survival rate of 97.1%.

摘要

目的

本前瞻性临床研究旨在评估在前上颌区域植入扩大型平台种植体并即刻用单冠修复的 5 年生存率。

材料与方法

将采用平台转换理念的种植体植入上颌牙槽骨的新鲜拔牙窝内，每位患者在种植体植入后即刻获得临时修复体。15 天后，插入最终螺丝固位修复体。在种植体植入后的第 1 天、第 1、3、6、9、12、24、36 个月和 5 年，使用数字化 X 线片评估近中和远中骨高度。使用 Osstell Mentor 设备的共振频率分析（RFA）测量初始稳定性。将 64 个种植体植入 32 名男性和 32 名女性患者，年龄 29-60 岁（平均 39.64±5.16 岁）。
